The Populist Backlash In opposition to Globalization: A Meta-Evaluation of the Causal Proof | British Journal of Political Science
The explosive progress of populism has remodeled politics to its core. Within the post-Second World Struggle period, dominated by liberal consensus, populism appeared primarily a Latin American phenomenon. Then, within the 2000s, populism – particularly its right-wing selection – started to unfold in Europe, as Fig. 1 exhibits. Its prominence jumped considerably with the 2014 European Parliament election, elevating UKIP and the Entrance Nationwide to the centre of consideration, adopted by the election of populist governments in Greece and Poland in 2015. Then, in 2016, populism reached the heartlands of the present world order with the Brexit referendum and the election of President Donald Trump.

The causes of populism are on the coronary heart of essentially the most important political and social science debates. One narrative contends that financial globalization resulted in actual struggling amongst less-educated working-class voters, catalyzing populism (Colantone and Stanig Reference Colantone and Stanig2018c; Rodrik Reference Rodrik2021). One other narrative contends that populism is an opposed response to cultural progressivism and that financial components aren’t related or solely related symbolically by way of perceptions of lack of cultural standing (Margalit Reference Margalit2019; Norris and Inglehart Reference Norris and Inglehart2019; Sides et al. Reference Sides2019). Though the proof means that the generational change argument urged by the canonical e book of Norris and Inglehart (Reference Norris and Inglehart2019) doesn’t maintain empirically (Grasso et al. Reference Grasso2019; Schäfer Reference Schäfer2022), the cultural narrative nonetheless appears to be notably influential. Of their evaluate of the structural determinants of right-wing populist voting, Amengay and Stockemer (Reference Amengay and Stockemer2019, 35) concluded that the ‘outcomes don’t lend assist to the financial hardship breeds extremism speculation’. Walter (Reference Walter2021, 9) concluded her evaluate by saying, ‘the proof that these instantly damage by globalization usually tend to vote for anti-globalization events or proposals is blended’. Lastly, Berman (Reference Berman2021, 75–76) reached an analogous conclusion, highlighting that ‘the proof linking particular person financial grievances to populist voting shouldn’t be notably sturdy’.
We enter the controversy on the populist backlash towards financial globalization by presenting the primary systematic evaluate and meta-analysis of the causal proof that financial insecurity considerably catalyzes populism. A key issue contributing to the widespread notion in regards to the lack of affiliation between financial components and populism is the dearth of readability concerning the definition of financial components. This vagueness manifests within the one-sided deal with individual-level financial hardships up to now and the neglect of contextual-level financial shocks and the temporal dimension; that’s, adjustments in financial components versus their degree.
Nevertheless, an absence of clear, cross-sectional, static affiliation between previous materials deprivation and populism doesn’t indicate that financial components are unimportant. As Mughan and Lacy (Reference Mughan and Lacy2002, 513) famous, financial insecurity is ‘a novel type of financial discontent that’s distinctive … from retrospective evaluations of short-term financial efficiency’. We’d like a extra fine-grained strategy to the economics of populist demand, reminiscent of financial insecurity. Latest research have proven that financial insecurity ‘has risen steadily for the reason that mid-Nineteen Eighties for just about all sub-groups of Individuals’ (Hacker et al. Reference Hacker2014, S5). Insecurity can also be widespread in Europe, extending ‘throughout revenue teams and occupational lessons, reaching into the center lessons’ (Ranci et al. Reference Ranci2021, 539). Subsequently, we deal with financial insecurity because the causal issue.
Systematic critiques (Dacombe Reference Dacombe2018) and meta-analyses (Borenstein et al. Reference Borenstein2009) are more and more fashionable in political science; they discover matters reminiscent of immigration and assist for anti-immigration events (Cools et al. Reference Cools2021), the impact of framing on political attitudes and habits (Amsalem and Zoizner Reference Amsalem and Zoizner2022), and the impact of the scale of the legislature on public spending (Freire et al. Reference Freire2023). Though the time period systematic evaluate is typically used to indicate narrative critiques performed with a scientific intent (Obinger and Petersen Reference Obinger and Petersen2017), systematic critiques differ from narrative critiques in vital methods. A scientific evaluate ‘locates current research, selects and evaluates contributions, analyzes and synthesizes knowledge, and experiences the proof in such a manner that permits fairly clear conclusions to be reached about what’s and isn’t recognized’ (Denyer and Tranfield Reference Denyer, Tranfield, Buchanan and Bryman2009, 672). By conforming to the requirements anticipated of major analysis, systematic critiques can considerably scale back bias, enhance transparency, and be topic to replication (Dacombe Reference Dacombe2018, 149). In addition they assist accumulate data and ‘present a foundation for planning and decoding new major analysis’ (Gough et al. Reference Gough and Gough2012, 3).
We mix a tutorial database search with a backward quotation search of the eligible research and a evaluate of lately revealed narrative critiques. We embrace research specializing in populist political habits as the end result and financial insecurity because the therapy and comply with a analysis design devoted to figuring out causality. We reviewed and synthesized thirty-six research fulfilling our inclusion standards, extracting 144-point estimates and learning their precision. We numerically summarize the principle outcomes and formally take a look at for publication bias. All thirty-six quasi-experimental research report a sturdy causal hyperlink between financial insecurity and populism. We additionally establish important geographic, methodological, and disciplinary divisions within the literature; the affiliation is powerful throughout these dimensions of heterogeneity. We discover important proof of publication bias, however the causal affiliation between financial insecurity and populism stays important after controlling for it.
Our paper proceeds as follows. First, we describe our systematic search technique and outline populism, financial insecurity, and quasi-experiments. After describing the method of inclusion and exclusion, we current the leads to three sections. First, we overview the principle outcomes and the geographic, methodological, and disciplinary divisions. Second, we synthesize the important thing outcomes utilizing the ‘vote counting’ strategy, which is appropriate for an exploratory numerical abstract of findings from extensively heterogeneous research. Third, we carry out formal statistical exams for publication bias. We begin by testing the density discontinuity of the distribution of t-statistics. Subsequent, we estimate a partial correlation coefficient to deal with heterogeneity within the therapy and final result variables and conduct a funnel plot asymmetry take a look at. Lastly, we current the conclusions.
Systematic Evaluate Methodology
Search Technique
We comply with the up to date 2020 model of the Most well-liked Reporting Objects for Systematic Evaluations and Meta-Analyses (PRISMA) pointers (Web page et al. Reference Page2021). These pointers set requirements for strong, clear, and replicable systematic critiques. Right here, we summarize the important thing search parameters and current an in depth overview of the search technique in Complement S1.
We searched three tutorial databases: Net of Science, Scopus, and EBSCO Discovery Service. The searches occurred between 26 January and 6 February 2022 and had been repeated between 19 and 25 July 2022. We included a mix of key phrases overlaying the end result of pursuits (populism), the therapy (financial insecurity), and the analysis design (causal inference). Desk S1.1 within the Complement (p.1) exhibits the entire search technique verbatim.
We looked for research that analyze populist political habits by way of final result. A lot of the tradition versus economic system debate is centred on far-right or right-wing populism. Nevertheless, left-wing populism can also be vital, particularly in Latin America and Southern Europe. Some posit that totally different types of populism is perhaps aggressive alternate options. For instance, the supply of left-wing populism would possibly scale back the demand for right-wing populism. Subsequently, we deal with populism basically, not simply right-wing populism. This strategy permits us to investigate whether or not the literature recognized important variations within the determinants of left-wing and right-wing populism.
Probably the most standard strategy within the literature identifies populism as a ‘thin-centred ideology’ that frames the elemental political cleavage between the elite and the pure folks (Mudde Reference Mudde2007). The strengths of this strategy are that it’s agnostic concerning the causes and the precise coverage content material of populism; is broad sufficient to seize a variety of the phenomenon, reminiscent of left- and right-wing; inclusionary or exclusionary populism; and particular sufficient to exclude non-populism. Regardless of the ubiquity of this definition, empirical researchers usually embrace events influenced by the notion of anti-establishment politics, a time period intently associated to populism (Barr Reference Barr2009; Mudde Reference Mudde2007).Footnote 1 Our goal is to not make clear the idea of populism or determine between totally different approaches however to seize all kinds of populist outcomes to replicate the heterogeneity of the literature. Thus, our definition contains the novel left, the novel proper, and historic precedents of populism, reminiscent of fascism in Europe or Latin-American import-substitution populism, reminiscent of Peronism (Guriev and Papaioannou Reference Guriev and Papaioannou2022, 11–13).
We began from a ‘nearest neighbor’ systematic evaluate and extracted the search string from Starvation and Paxton (Reference Hunger and Paxton2022), whose search technique relied on the phrase stem ‘populis*’. Along with populism, we included key phrases that cowl anti-establishment politics and totally different variations of the novel proper and the novel left to cowl totally different valances of populism, even when the phrase populism shouldn’t be talked about within the summary or title.
Financial insecurity captures a number of dimensions of vulnerability and depends on a dynamic focus to investigate change throughout time (Whelan and Maître Reference Whelan and Maître2005). We outline financial insecurity because the ‘danger of financial loss confronted by employees and households as they encounter the unpredictable occasions of social life’ (Western et al. Reference Western2012, 342). Western et al. argue that these adjustments are linked to opposed occasions or exterior shocks (originating within the labor market, the housing market, the monetary market, over-indebtedness, well being occasions, and so forth.). Thus, we embrace search phrases to cowl varied types of materials hardship and different sources of financial insecurity, reminiscent of ‘financial uncertainty’, ‘monetary uncertainty’, or ‘labor market uncertainty’. As a result of ‘residents’ financial worries largely monitor publicity to substantial financial shocks’ (Hacker et al. Reference Hacker2013, 23), we additionally used key phrases that seize upstream shocks, reminiscent of ‘commerce shocks’, ‘import publicity’, austerity, or robotization.
Research following a causal inference analysis design (additionally known as ‘pure experiments’ or ‘quasi-experiments’) ‘goal to make causal inferences concerning the results of an publicity or interventionFootnote 2 of curiosity on outcomes by exploiting exogenous variation in therapy project’ (Glanville et al. Reference Glanville2017, 68). Research following a causal inference analysis design attempt to establish causality and mimic experimental designs by figuring out an exogenous ( ‘nearly as good as random’) supply of variation in therapy project. Nevertheless, ‘quasi-experiments’ aren’t experiments; they depend on a number of figuring out assumptions which might be generally credible and generally extra demanding.Footnote 3 Cools et al. (Reference Cools2021) performed a scientific evaluate of the causal proof on populist proper voting however didn’t present a precise search string, so we extracted the search string from El Soufi and See (Reference El Soufi and See2019). We prolonged their string with different key phrases based mostly on causal inference textbooks (Cunningham Reference Cunningham2021; Huntington-Klein Reference Huntington-Klein2022) – instrumental variables, difference-in-differences, regression discontinuity, artificial management designs, survey experiments, discipline experiments, and randomized managed trials.Footnote 4
Developing the search this manner runs the danger of lacking research that don’t consult with their causal design within the title or summary. We minimized this danger by counting on two extra search methods described under. First, we performed a backward quotation search based mostly on the bibliography of the seventeen research we recognized after screening and eligibility. Second, we reviewed the bibliographies of lately revealed narrative critiques on populism.
Inclusion and Exclusion
The PRISMA move diagram in Fig. 2 describes the screening course of. Our preliminary database search recognized 1,234 research: 483 by way of EBSCO Discovery, 461 by way of Scopus, and 290 by way of Net of Science. Of those, we recognized 446 duplicates utilizing automated identification in EndNote. This left 788 research for screening. As well as, we recognized 625 information by way of quotation looking out (553 on Scopus, 62 on Net of Science, and 6 by way of evaluate of critiques) and 4 additional research by way of Google Scholar. These 625 research had been included within the second spherical of screening based mostly on the inclusion and exclusion standards detailed under. We included research in the event that they fulfilled the next inclusion standards:
-
(a) the end result variable is instantly associated to populist political habits or orientation,
-
(b) the therapy is said to financial insecurity broadly outlined,
-
(c) the examine identifies a causal affiliation by way of a quasi-experiment, discipline experiment, or survey experiment,
-
(d) the examine depends on authentic, major empirical analysis.
Determine 2. PRISMA move diagram.
Screening the titles and abstracts of the 788 research recognized by way of major database search, we excluded 702 research. This left 86 research whose full texts had been retrieved and assessed for eligibility by studying the entire examine. At this stage, we excluded 69 research. Nevertheless, we recognized 17 eligible research through the first spherical.
As talked about above, we additionally recognized 625 research for screening by way of a backward quotation search and a evaluate of critiques. After screening and eligibility, we searched the bibliographies of the 17 research we recognized. We used Scopus and Net of Science to extract the references cited and located 553 additional research in Scopus and 62 in Net of Science. We reviewed the bibliographies of lately revealed critiques on populism (Berman Reference Berman2021; Guriev and Papaioannou Reference Guriev and Papaioannou2022; Starvation and Paxton Reference Hunger and Paxton2022; Mansfield et al. Reference Mansfield2021; Rodrik Reference Rodrik2021; Scheiring Reference Scheiring and Sajó2021; Tuğal Reference Tuğal2021; Walter Reference Walter2021) and recognized 6 additional research for screening. Lastly, we recognized 4 research by way of a Google Scholar quotation search. Of those 625 research, we excluded 541 throughout screening on summary and title. We retrieved 84 full-text research for an in depth evaluation of eligibility. Of those, we excluded 65. This fashion, the quotation search and evaluate of critiques yielded 19 eligible research for inclusion.
We extracted the principle examine parameters right into a abstract desk, which included creator(s), title, nations analyzed, sampled models, pattern dimension, examine time, major final result, therapy, degree of the therapy and final result variable, experimental design, knowledge construction, modelling particulars, strategy to missingness, and abstract outcomes, amongst others. This detailed evaluate desk is accessible as a part of the replication knowledge. Altogether, we discovered thirty-six eligible research, as summarized in Table 1.
Desk 1. Overview of the research
Overview of the Literature
We discovered important heterogeneity in a number of dimensions. Most research analyze Western Europe and North America, the place most authors are situated. Japanese Europe outdoors the EU, Latin America (besides Brazil), Asia, and Africa are uncared for, as Tuğal (Reference Tuğal2021) and Mansfield et al. (Reference Mansfield2021) famous.
This geographic skew results in a neglect of particular sources of financial insecurity. Shocks associated to robotization are concentrated in essentially the most superior economies (Anelli et al. Reference Anelli2021; Frey et al. Reference Frey2018). Eurozone nations had been extra uncovered to import shocks than non-Eurozone European nations (Guiso et al. Reference Guiso2019). Nevertheless, this doesn’t imply that different types of globalization shock weren’t essential in rising economies. Ahlquist et al. (Reference Ahlquist2020) and Gyongyosi and Verner (Reference Gyongyosi and Verner2022) present that overseas foreign money debt shocks had been vital components behind the rise of right-wing populism in Japanese Europe, whereas Barros and Santos Silva (Reference Barros and Santos Silva2019) present that male-specific labor market insecurity fuelled assist for Bolsonaro.
Most research analyze the populist radical proper by way of the end result variable. A smaller group of research explores the entire populist spectrum (each left and proper), some research analyze populist attitudes, however just one concentrates on the populist left. Instrumental variables dominate the sector in major causal inference design, however difference-in-differences and regression discontinuity designs are additionally fashionable. Economists strongly desire contextual-level measurements of populism, whereas political scientists are extra open to individual-level variables. These disciplinary variations would possibly affect substantive findings. Berman (Reference Berman2021, 75–6) lately famous that financial grievance-based explanations are stronger on the contextual degree, whereas cultural explanations are stronger on the particular person degree. Complement S2 (pp.3–6 of the net Complement) presents an in depth overview of the research’ geographic, methodological, and disciplinary heterogeneity.
To synthesize the substantive outcomes of the evaluate, Fig. 3 presents a conceptual overview of the multi-channel causal relationship between financial insecurity and populism based mostly on the reviewed research (with the variety of research assessing the precise therapy in parentheses). Relating to the experimental therapy, the supply of financial insecurity and import publicity (‘the China shock’) stands out within the variety of research that analyze it. Labor market uncertainty is the second most frequently analyzed trigger. Different therapy variables deal with austerity, redistribution, automation, overseas foreign money debt shocks, subjective financial hardship, financial institution failure, and housing demand shock. The literature additionally recognized vital moderators, reminiscent of class, schooling, age, intercourse, race/ethnicity, political provide, and social safety insurance policies. These moderators affect how the lived expertise of financial shocks interprets into populism. Complement S3 (pp.10–16) presents an in depth narrative overview of the literature specializing in the principle causes of the populist backlash.
Determine 3. The multi-channel causal relationship between financial insecurity and populism.
All thirty-six research report a sturdy causal hyperlink between financial insecurity and populism. A number of research report a robust impact. A recurring impact is that financial shocks and financial insecurity clarify round one-third of latest surges in populism. A number of research additionally confirmed that greater financial safety by way of redistribution dampens voters’ enthusiasm for populism (Albanese et al. Reference Albanese2022; Crescenzi et al. Reference Crescenzi2020). As Guiso et al. (Reference Guiso2019, 101) concluded, ‘if one desires to defeat populism, one should first defeat financial insecurity’.
Some research recommend that adjustments in political provide affect how financial insecurity interprets into political outcomes. For instance, as soon as the 5 Star Motion appeared in Italy, it efficiently attracted the votes of commerce victims beforehand channeled by radical-right events. Thus, when introduced with an alternate, victims of commerce shocks don’t essentially select a radical proper populist social gathering (Caselli et al. Reference Caselli2021). America gives an reverse instance. Right here, the Democrats benefited from the discontent of commerce victims through the presidential elections earlier than 2012. Nevertheless, since 2012, Republicans have change into extra profitable in attracting the victims of commerce shocks, resulting in Trump’s 2016 victory (Autor et al. Reference Autor2020; Che et al. Reference Che2016). This aligns with the extant literature displaying that centre-left events are notably susceptible to transferring towards the best in financial coverage (Bagashka et al. Reference Bagashka2022; Fervers Reference Fervers2019; Mudge Reference Mudge2018; Snegovaya Reference Snegovaya2024). With out left-wing progressive insurance policies and narratives, radical-right populists can mobilize dissent by way of culturally symbolic points, utilizing the nation as an imagined solidarity neighborhood that protects towards globalization (Berman and Snegovaya Reference Berman and Snegovaya2019; Scheiring Reference Scheiring2020).
Six research discover that the cultural backlash shouldn’t be an alternate mechanism however a mediator. For instance, Anelli et al. (Reference Anelli2021) discover that robotization will increase nativism, standing threats, and cultural traditionalism in Europe. Autor et al. (Reference Autor2020) discover that import publicity in the USA (US) within the 2000s elevated the recognition of the conservative media and conservative viewpoints. Utilizing an revolutionary survey experiment, Rhodes-Purdy et al. (Reference Rhodes-Purdy2021) present that financial decline induces cultural discontent mediated by financial anger, whereas cultural discontent, in flip, catalyzes populism. Colantone and Stanig (Reference Colantone and Stanig2018a) discover that financial insecurity by way of import publicity results in a shift in direction of anti-liberal values within the area of politics however not within the extra-political area, reminiscent of child-rearing. This consequence implies that the populist backlash is neither a results of a persistent authoritarian outlook nor an expression of a common shift within the route of the authoritarian persona. As an alternative, Colantone and Stanig (Reference Colantone and Stanig2018a) argue that scepticism in direction of liberal values and liberal democracy is a political manifestation of misery pushed by financial insecurity. In fact, the existence of such mediation, the place financial insecurity is the first trigger, doesn’t imply that cultural components aren’t vital; they are often unbiased major causes, too. It implies that juxtaposing economic system and tradition is much less productive than exploring their interactions.
Research following causal inference designs are thought of among the many highest high quality research within the universe of observational research. Subsequently, we didn’t carry out a scientific high quality evaluation. Nevertheless, some research make use of much less efficient identification methods that require extra demanding assumptions. The sector is riddled with methodological controversies and frequent improvements. Finally, the credibility of causal inference designs depends upon the authors’ skill to show the exogeneity of the therapy. As customers of empirical analysis, we must always at all times think about these design limitations.
It’s uncommon for a scientific evaluate to yield such conclusive outcomes, with all research pointing in the identical route. This unanimity would possibly replicate publication bias. Publishing solely outcomes that discover a important impact disturbs the standard and reliability of the general image rising from the literature (Brodeur et al. Reference Brodeur2020; Thornton and Lee Reference Thornton and Lee2000). To maximise the probabilities of discovering null outcomes, we searched the out there gray literature, together with working papers and PhD theses which might be extra more likely to report null outcomes than revealed articles or convention papers (Thornton and Lee Reference Thornton and Lee2000, 211). Nevertheless, non-published papers additionally all report a major constructive impact of financial insecurity on populism.
Meta-Evaluation
Due to the appreciable heterogeneity in examine designs, populations, remedies, and outcomes, evaluating the impact sizes throughout research counting on a typical meta-regression shouldn’t be acceptable. To sort out this problem, we depend on two totally different approaches. First, we quantify the outcomes utilizing the extensively used however considerably naïve ‘vote counting’ strategy, which counts the variety of important and insignificant associations (Amengay and Stockemer Reference Amengay and Stockemer2019; Bushman and Wang Reference Bushman, Wang and Cooper1994; Geys Reference Geys2006). Whereas this methodology has vital limitations (Stanley and Doucouliagos Reference Stanley and Doucouliagos2012, 43–5), it permits for an exploratory numerical abstract of outcomes throughout a variety of heterogeneous research.
Second, to formally take a look at for publication bias and additional analyze the heterogeneity within the outcomes, we depend on a standardization process borrowed from latest meta-analysis literature by calculating a partial correlation coefficient (Borenstein et al. Reference Borenstein2009; Brodeur et al. Reference Brodeur2020; Filomena and Picchio Reference Filomena and Picchio2023; Gechert and Heimberger Reference Gechert and Heimberger2022; Jin et al. Reference Jin2015; Stanley and Doucouliagos Reference Stanley and Doucouliagos2014). We consider publication bias by conducting a funnel-asymmetry and precision-effect take a look at and analyzing the density discontinuity of t-statistics.
We constructed a meta-dataset by together with the principle estimates reported within the thirty-six research, which included 144 estimates from the research (see Complement S4 for the inclusion standards). The variety of estimates per examine ranged between a minimal of 1 and a most of 10. For every estimate, we extracted the t-statistic and normalized their signal so {that a} constructive signal means a rise in populism derived from elevated financial insecurity.Footnote 5
‘Vote Counting’ Method Statistics
We counted the variety of important positives (generally known as ‘successes’), important negatives (generally known as ‘anomalies’), and insignificant associations (additionally known as ‘failures’) and calculated the share of positives (generally known as the ‘success fee’ of the precise variable). The upper the share of positives, the extra assured we will be in uncovering a ‘true’ affiliation. We summarize the outcomes of this ‘vote counting’ strategy in Table 2. Whereas every examine experiences a minimum of one mannequin that exhibits a majorFootnote 6 constructive affiliation, some estimates diverge from this total image. Of the 144 estimates, 96 present a major constructive affiliation, 7 present a major destructive affiliation, and 41 present no important affiliation. The destructive anomalies come from varied sub-samples, revealing fascinating patterns of heterogeneity.
Desk 2. Summarizing the impact of financial insecurity on populism
For instance, Guiso et al. (Reference Guiso2019) discover that import publicity boosts populism in Eurozone nations however discover a important destructive hyperlink in non-Eurozone nations (primarily Japanese Europe).Footnote 7 One other fascinating instance is Baccini and Weymouth (Reference Baccini and Weymouth2021), who discover that non-white voters’ publicity to deindustrialization led to greater assist for the Democrats in 2016, whereas white voters uncovered to deindustrialization turned to the Republicans to assist Trump. These variations present that id politics and financial dislocations work together in producing assist for populism. Barros and Santos Silva (Reference Barros and Santos Silva2019) additionally discover that gender id interacts with labor market insecurity in Brazil: males uncovered to labor market insecurity had been considerably extra more likely to vote for Bolsonaro. The alternative is true for girls.
Table 2 additionally exhibits that every therapy has a share of positives exceeding 50 per cent, with the typical share reaching 67 per cent. In different phrases, the modal class is ‘success’ for every therapy. The pattern dimension is small as a result of the research/remedies weren’t randomly chosen. Consequently, the variations are important throughout remedies, and we have to be cautious when evaluating the share of positives throughout the therapy classes. The variability throughout the remedies may replicate a mixture of true impact heterogeneity, publication bias, specification bias, or variations in sampling. Automation, financial institution failure, import publicity, labor market uncertainty, and redistribution (reversed) appear extra ambiguous predictors of populism than financial insecurity on ‘common’. Austerity, overseas foreign money debt shock, housing demand shock, and subjective financial hardship appear much less ambiguous predictors to foretell populism extra robustly.
Table 3 exhibits the outcomes damaged down by the kind of populism. Altogether, 15 fashions had been estimated for left-wing and 100 for right-wing populism. The remaining 29 estimates don’t differentiate between left and proper. Total, financial insecurity appears to foretell right-wing populism extra robustly (share of positives 65 per cent) than left-wing populism (40 per cent). Automation, labor market uncertainty, and redistribution might sound most related for left-wing populism. Austerity, overseas foreign money debt shocks, housing demand shocks, and import publicity appear extra related for right-wing populism. The identical caveat applies: we have to be cautious when evaluating the share of positives throughout the therapy classes.
Desk 3. The impact of financial insecurity on left-wing and right-wing populism
Publication Bias
Figure 4 plots the density operate of t-statistics of the estimates included within the meta-analysis. If there is no such thing as a publication bias, there needs to be no important discontinuities within the distribution at vital values reminiscent of t = 1.96 (when the p-value would equal 0.05). Fig. 3, we will infer a discontinuity within the distribution of t-values round these vital factors.
Determine 4. Density discontinuity of the t-statistics.
Notes: The strong strains characterize the non-parametric native polynomial density estimator of Cattaneo et al. (Reference Cattaneo2018). The coloured areas round are 95 per cent confidence intervals. The null speculation of no discontinuity at t = 1.96 can’t be rejected at a 5 per cent significance degree (p-value = 0.607). The highest and backside 1 per cent of the t-statistic distribution had been excluded from the graph for illustrating functions however not from the density estimator and the take a look at.
Nevertheless, utilizing the non-parametric native polynomial density estimator with strong bias-correction of Cattaneo et al. (Reference Cattaneo2018), we can’t reject the null speculation of no discontinuities at a worth t = 1.96 (p-value of the take a look at = 0.607). Following Filomena and Picchio (Reference Filomena and Picchio2023), we ran a two-sided binomial take a look at for the null speculation of equal mass throughout totally different home windows across the t = 1.96 cut-off. On this case, all exams reject the null speculation and level towards important publication bias (see Desk S4.1 on p.17 of the Complement).
Does publication bias invalidate the general affiliation? The funnel plot take a look at can present a statistical reply. Nevertheless, as already famous, the causal impact of financial insecurity on populism shouldn’t be instantly comparable throughout the fashions utilized in every examine. Subsequently, we calculate the partial correlation coefficient as a standardized ‘impact dimension’ to make the estimates comparable. This measure has been utilized in earlier social science meta-analyses (Filomena and Picchio Reference Filomena and Picchio2023; Stanley and Doucouliagos Reference Stanley and Doucouliagos2014) and is calculated as follows:
the place t i is the t-statistic from the causal estimate, and dk i is the levels of freedom within the mannequin from which the estimate is derived. For the reason that variety of covariates shouldn’t be reported in many of the fashions, we substitute dk i by the variety of observations minus one, following Filomena and Picchio (Reference Filomena and Picchio2023). The partial correlation coefficient p i varies from −1 to 1. A p i better (decrease) than zero implies that populism will increase (decreases) due to financial insecurity. p i measures the energy of the statistical significance of the impact, though it doesn’t have a direct quantitative that means of the impact dimension (Filomena and Picchio Reference Filomena and Picchio2023; Gechert and Heimberger Reference Gechert and Heimberger2022; Stanley and Doucouliagos Reference Stanley and Doucouliagos2014).Footnote 8
The inverse funnel plot in Fig. 5 serves as a visible inspection take a look at for publication bias. The funnel plot in Fig. 5 doesn’t appear to be totally symmetric.Footnote 9 Whereas extra exact estimates (on the prime) appear nearer to zero, much less exact estimates (on the backside) are targeting the best, displaying a stronger impact of financial insecurity on populism. This might point out publication bias.
Determine 5. Inverse funnel plot.
Notes: Every circle represents the totally different estimates included within the meta-analysis (n = 144). The purple vertical line represents the imply of the partial correlation coefficient (p = 0.0579).
The Funnel Asymmetry Precision Impact take a look at (FAT-PET) formally exams for a correlation between the partial correlation coefficient and its normal error. It’s based mostly on the next regression:
the place p i,j is the partial correlation coefficient of the estimate I from examine j, SE (p i,j) is the usual error, and e i,j is the error time period. If ∝1 = 0, there is no such thing as a proof for publication take a look at (Funnel Asymmetry Check, FAT). On the similar time, if ∝0 ≠ 0, we will conclude that there stays a ‘true’ impact after accounting for publication bias (Precision-Impact take a look at) (Gechert and Heimberger Reference Gechert and Heimberger2022; Stanley and Doucouliagos Reference Stanley and Doucouliagos2014). To account for heteroskedasticity, we estimate equation (2) by weighted least squares (WLS) utilizing the inverse of the squared normal errors as weights (Gechert and Heimberger Reference Gechert and Heimberger2022; Stanley and Doucouliagos Reference Stanley and Doucouliagos2014). We cluster normal errors on the examine degree j to account for correlation between estimates from the identical examine.
Table 4 experiences the outcomes of the regression. Mannequin (1) experiences the straightforward mannequin. Mannequin (2) experiences an instrumental variable estimation utilizing the sq. root of the variety of observations as an instrumental variable since SE (p i,j) is perhaps endogenous attributable to measurement error (Filomena and Picchio Reference Filomena and Picchio2023). In Mannequin (3), we substitute SE (p i,j) by its sq. to account for non-linearities, as this was the popular mannequin within the presence of publication bias (Stanley and Doucouliagos Reference Stanley and Doucouliagos2014).
Desk 4. Funnel-asymmetry precision-effect take a look at outcomes
All mannequin outcomes level towards the presence of publication bias; they report a major affiliation between the partial correlation coefficient and its normal error ( ∝ 1 > 0). Nevertheless, crucially, additionally they present a remaining ‘true’ impact after accounting for publication bias ( ∝ 0 > 0). After adjusting for publication bias, the ‘true’ partial correlation coefficient can be 0.016,Footnote 10 in comparison with the imply of 0.058. Whereas the partial correlation coefficient doesn’t have a quantitative interpretation, these outcomes level to a ‘true’ constructive impact of financial insecurity on populism after accounting for publication bias. Nevertheless, it’s not as sturdy because the one we’d get from a easy common of the standardized ‘impact sizes’.
Heterogeneity Evaluation
Lastly, following Gechert and Heimberger (Reference Gechert and Heimberger2022) and Filomena and Picchio (Reference Filomena and Picchio2023), we take a look at whether or not totally different examine traits affect the probability of reporting a major impact. We do that by extending Fashions 1 and three in Table 4, together with the explanatory categorical variables measuring examine traits that we additionally used within the vote-counting strategy. These are the populism final result variable, major therapy variable, area, self-discipline, and first experimental design. The omitted baseline classes characterize the classes with the biggest pattern dimension in every case. Suppose a examine attribute considerably correlates with the Partial Correlation Coefficient (PCC). In that case, it may be interpreted as statistical proof that research with the attribute in query usually tend to report a major impact between financial insecurity and populism in comparison with the omitted baseline class whatever the pattern dimension (Stanley and Doucouliagos Reference Stanley and Doucouliagos2012).
Table 5 presents the outcomes. First, the kind of populism final result appears to make no distinction to the probability of discovering an impact from financial insecurity. In alignment with the outcomes based mostly on the vote-counting strategy, we discover that research testing the impact of austerity, financial institution failure, overseas foreign money debt shock, housing demand shock, and subjective financial hardship are considerably extra more likely to report a major impact on populism than research testing the impact of import publicity, internet of the impact of publication bias. Research from totally different areas are equally more likely to report important results. Research revealed in political science journals usually tend to report a extra important impact than research revealed in economics journals. Lastly, research counting on difference-in-differences and survey experiments to establish causality are statistically much less more likely to report a major impact of financial insecurity on populism. The fixed is critical in every specification, which displays the presence of a major ‘true’ impact of financial insecurity on populism in a ‘typical’ examine,Footnote 11 internet of publication bias.

Concluding Dialogue
We introduced the primary systematic evaluate and meta-analysis of the causal proof of financial insecurity as a catalyst of populism. We performed a two-pronged systematic search to establish eligible research, combining a database search with a seek for citations of eligible research and lately revealed narrative critiques. We included research that targeted on populist political habits as the end result of financial insecurity as therapy and adopted a causal inference analysis design. Though we discovered important heterogeneity in a number of dimensions, all thirty-six research report a major affiliation between financial insecurity and populism. A recurring impact dimension is that financial insecurity explains round one-third of latest surges in populism. Tallying the variety of profitable, constructive important associations throughout 144 causes exams performed within the thirty-six research, we discovered that the general share of great constructive associations (successes) was 67 per cent, with every causal therapy exceeding the 50 per cent threshold.
Financial insecurity appears notably related for explaining right-wing populism, whereas the outcomes for left-wing populism seem extra ambiguous. Researchers have ceaselessly analyzed import shocks, with strong causal proof throughout 13 research. Nevertheless, judging by the robustness of particular person exams extracted from the research, housing demand shocks, subjective financial hardship, austerity, and overseas foreign money debt shocks look like essentially the most strong causes of populism.
Altogether, the prevailing scholarship presents sufficient proof to conclusively disperse any doubts concerning the causal function of financial insecurity within the populist backlash towards globalization. We explored whether or not the affiliation displays the underlying affiliation or is contaminated by publication bias. We estimated a partial correlation coefficient to standardize the outcomes, performed a funnel-plot asymmetry take a look at, and examined the density discontinuity of the distribution of t-statistics. These exams confirmed appreciable proof for publication bias. The underlying impact is probably going smaller than the general impact from the thirty-six research. Nevertheless, the affiliation between financial insecurity and populism stays important after controlling for publication bias.
The robustness of this causal affiliation contrasts with the picture rising from some latest narrative critiques that elevate doubts concerning the relationship between financial insecurity and populism. We are able to establish three components to clarify this distinction. First, we outlined financial safety extra broadly than political scientists utilizing correlational designs with individual-level attitudinal knowledge usually do. We included measures of financial hardship, reminiscent of unemployment, and contextual-level shocks and types of financial insecurity that didn’t result in absolute materials deprivation. On the particular person degree, political-cultural attitudes would possibly cancel out the impact of financial hardship. Against this, the impact of contextual-level shocks and financial insecurity on populism is perhaps stronger.
Second, most informal designs require measuring temporal change, whereas correlational research are sometimes cross-sectional. Cross-sectional designs foreground the results of slow-changing or secure attributes reminiscent of political tradition. Proper-wing populist attitudes are highly effective predictors of right-wing populist voting. Nevertheless, dynamic designs foreground change. These marginal results would possibly spotlight the centrality of particular populations with particular experiences that change their voting habits between elections, even when they continue to be a minority within the social gathering’s total electoral base. In brief, dynamic designs higher seize the causes of the rise/change in assist for populism. Against this, cross-sectional designs can higher seize the long-standing traits of populist supporters.
Third, systematic critiques and meta-analyses systematically map the out there proof. Against this, narrative critiques aren’t systematic, leaving extra room for the researchers’ assumptions, pre-analytical visions, methodological preferences, and discipline-specific data to affect the research analyzed – as famous above. Totally different disciplines may also have a look at the causes of populism from totally different angles. Economists would possibly dedicate extra vitality to analyzing financial components, whereas political scientists would possibly dedicate extra vitality to political provide or political tradition. We managed for a number of of those examine traits, which didn’t affect the principle affiliation between financial insecurity and populism. Along with methodological and disciplinary results, the impact of prevalent views in scholarly publications and the general public media may additionally affect non-systematic, narrative critiques. Whereas our examine establishes strong causal proof between financial insecurity and populism, a lot stays to be executed to systematize what now we have realized up to now. Our examine is only a first step.
By specializing in causal designs, we bracket a major physique of literature that follows correlational designs. We don’t assume that causal designs are inherently superior to correlational designs. Correlational designs have a number of vital benefits over causal designs. They’re extra versatile, their exterior validity is normally stronger, and they are often utilized to investigate a variety of phenomena for which it will be unimaginable to assemble a reputable causal design. Nevertheless, our major goal is to handle the widespread notion within the literature that the affiliation between financial insecurity and populism is weak. The strongest reply to this query emerges from quasi-experimental research that set up a causal affiliation and prioritize inside validity. We designed our search standards with this major goal in thoughts.
Regardless of this narrower deal with causal inference, the outcomes of our systematic evaluate match properly with the broader correlational literature. First, a central debate in political science has revolved across the altering political cleavage constructions of superior Western democracies. New populist proper events gained growing momentum by combining their conventional middle-class base with working-class voters; that’s, the ‘losers of modernization’ (Betz Reference Betz1993; Swank and Betz Reference Swank and Betz2003) or the ‘losers of globalization’ (Hooghe and Marks Reference Hooghe and Marks2018; Kriesi et al. Reference Kriesi2006). Within the age of organized Fordist welfare capitalism, working-class members had an opportunity to enter the center class. This pattern has stopped and even been reversed in superior democracies.
Second, a newer stream of research, partly from the cleavage literature, has examined the results of latest labour market dangers and financial insecurities, arguing that juxtaposing losers vs. winners is perhaps deceptive. Help for right-wing populism is linked to the rising sense of insecurity amongst previously protected ‘labor market insiders’ who’ve a level of fabric safety to lose however aren’t among the many greatest victims (Häusermann Reference Häusermann2020; Kurer Reference Kurer2020). Researchers have highlighted a number of associated channels, reminiscent of social decline (Engler and Weisstanner Reference Engler and Weisstanner2021), the geographical focus of financial discontent (Rodríguez-Pose Reference Rodríguez-Pose2018), revenue inequality (Han Reference Han2016), housing costs (Adler and Ansell Reference Adler and Ansell2020), and relative group deprivation (Burgoon et al. Reference Burgoon2018; Rico and Anduiza Reference Rico and Anduiza2019).
Third, associated to the notion of insecurity, standing lossFootnote 12 (Gidron and Corridor Reference Gidron and Hall2017), and standing discordanceFootnote 13 (Kurer and Van Staalduinen Reference Kurer and Van Staalduinen2022) look like a stronger predictor of the populist vote than extra direct measures of financial deprivation, reminiscent of unemployment. This underpins the significance of using fine-grained measures of financial insecurity, as emphasised in our examine. The notion of standing loss or discordance additionally permits researchers to know the mutually reinforcing – financial and cultural – double devaluations of working-class abilities, values, and existence which might be more and more at odds with the calls for of the globalized post-industrial economic system (Friedman Reference Friedman and Friedman2003; Kalb Reference Kalb2023). Recognizing the interrelations between cultural and financial devaluations permits researchers to establish how broad populist social coalitions emerge (Halikiopoulou and Vlandas Reference Halikiopoulou and Vlandas2020). These correlational research make clear essential points of the financial insecurity-populism mechanism, in keeping with the conclusions arising from the current evaluation.
Our systematic evaluate has a number of coverage implications. The literature exhibits that there’s not one sort of populist voter however a number of varieties, which implies there is perhaps a number of related coverage channels to handle the rise of populism. Traditional welfare insurance policies, reminiscent of a greater social security internet and extra redistribution, are essential to guard the victims of globalization. New insurance policies that shield towards rising insecurities and dangers would possibly scale back the urge for food for populism among the many downwardly cell working-middle class. We don’t see these coverage selections as alternate options however as complementary options. These insights resonate with the coverage conclusions rising from the extant correlational literature. Swank and Betz (Reference Swank and Betz2003) have already reported that globalization is extra robustly related to assist for the populist proper in nations with decrease ranges of social safety. This affiliation was later confirmed by Foster and Frieden (Reference Foster and Frieden2019). In a associated examine, Vlandas and Halikiopoulou (Reference Vlandas and Halikiopoulou2019) confirmed that unemployment advantages and employment safety restricted the affect of unemployment on far-right social gathering assist.
Relating to newly rising dangers, reminiscent of automation, Gingrich (Reference Gingrich2019) discovered that whereas compensation for automation could assist left-wing events retain vote share among the many uncovered, it doesn’t appear to forestall the rise of the populist proper. Against this, Vlandas and Halikiopoulou (Reference Vlandas and Halikiopoulou2022) discovered that welfare state insurance policies scale back the probability of supporting the far proper amongst people uncovered to excessive dangers, together with the unemployed, pensioners, low-income employees, workers on non permanent contracts, people in giant households, and people who’re disabled/completely sick. Our evaluate confirms the relevance of a number of redistributive and protecting welfare insurance policies recognized within the literature.
Lastly, our systematic evaluate and meta-analysis uncovered a number of blind spots and open questions. First, whereas the examine area doesn’t have an effect on the probability of reporting a major impact, the literature exhibits important substantive impact heterogeneity throughout geographical contexts. For instance, some causes related in Western Europe is perhaps much less related in Japanese Europe. Thus, correcting the heavy geographical skew of the literature is crucial. Focusing extra on the expertise of growing and rising economies may yield new insights into how financial insecurity impacts populism. Second, researchers ought to pay extra consideration to cross-study comparability. The disciplinary variations in design may strengthen disciplinary silos and result in divergent outcomes throughout research and disciplines, which needs to be prevented.
Third, the outcomes recommend {that a} strict juxtaposition of interest-based financial determinants vs. symbolic cultural components shouldn’t be fruitful. Specializing in the lived expertise of financial insecurity, co-evolution, and the interplay of cultural-symbolic and financial components permits researchers to bypass this tradition/economic system dichotomy. Lastly, the function of political provide and redistributive insurance policies in mitigating the impact of financial insecurity on populism stays an under-researched space. Politics can scale back financial insecurity, taking the wind from populists’ sails. Future analysis ought to pay extra consideration to those questions, which haven’t obtained sufficient consideration up to now.
