Models for converting expert-coded data to estimates of latent concepts assume different data-generating processes (DGPs). In this paper, we simulate ecologically valid data according to different assumptions, and examine the degree to which common methods for aggregating expert-coded data (1) recover true values and (2) construct appropriate coverage intervals. We find that the mean and both hierarchical Aldrich–McKelvey (A–M) scaling and hierarchical item-response theory (IRT) models perform similarly when expert error is low; the hierarchical latent variable models (A-M and IRT) outperform the mean when expert error is high. Hierarchical A–M and IRT models generally perform similarly, although IRT models are often more likely to include true values within their coverage intervals. The median and non-hierarchical latent variable models perform poorly under most assumed DGPs.

This paper estimates the effect of automatic voter registration (AVR) on voter turnout in California and Oregon. AVR systems register to vote all eligible individuals who transact with proscribed government agencies, most commonly the Department of Motor Vehicles (DMVs). The article isolates one part of the causal impact of AVR on turnout by taking advantage of a temporal feature of license renewals. Many individuals interact with the DMV periodically due to the need to renew drivers' licenses. Because licenses in both California and Oregon expire on birthdays, an individual's birth date can be treated as an exogenous variable discriminating between some individuals who are registered to vote in time for the election, while others are not. Our instrumental variable analysis compares registration and voting rates for individuals with birth dates prior and subsequent to the voter registration deadline. After calculating a causal effect of AVR on turnout at the individual level, we extrapolate this AVR “birthday” effect to overall voter turnout for these states.

Research on Russian troll activity during the 2016 US presidential campaign largely focused on divisive partisan messaging. Here, we document the use of apolitical content—content that could counteract mobilization efforts and escape detection in future campaigns. We argue this resembled techniques used by autocratic regimes domestically, in “flooding” social media with entertainment content to distract from and displace mobilizing messaging. Using automated text analysis and hand coding to construct a timeline of IRA messaging on Twitter, we find left-leaning trolls posted large volumes of entertainment content in their artificial liberal community and shifted away from political content late in the campaign. Simultaneously, conservative trolls were targeting their community with increases in political content. This suggests the use of apolitical content might be an overlooked strategy to selectively manipulate levels of attention to politics.

How does trade openness affect individuals’ social policy preferences in emerging markets? Drawing upon the theories of economic openness, risk, and social policy preference, we examine how trade openness and job sectors jointly shape preferences on social protection in China, the largest emerging market. Using the World Value Survey (WVS) Wave VI and archival macroeconomic indicators in 2012, we find that trade openness is associated with higher demands for government responsibility in social protection. We also find, compared with public-sector employees, private-sector employees exhibit lower levels of support to the role of government in social protection. The public–private divide in policy preferences, nevertheless, diminishes in regions with high levels of trade openness. This research provides new evidence to the risk-model of social policy preferences in the Chinese context. It also highlights the importance of considering the significant differences between public and private-sector employees in their social policy preferences.

When analyzing data, researchers are often less interested in the parameters of statistical models than in functions of these parameters such as predicted values. Here we show that Bayesian simulation with Markov-Chain Monte Carlo tools makes it easy to compute these quantities of interest with their uncertainty. We illustrate how to produce customary and relatively new quantities of interest such as variable importance ranking, posterior predictive data, difficult marginal effects, and model comparison statistics to allow researchers to report more informative results.

People's willingness to forgive corrupt government officials has intrigued many researchers. According to a prominent explanation, citizens tolerate corrupt officials in exchange for their ability to deliver public benefits, such as promoting economic development. We contextualize this corruption–competence tradeoff thesis by assessing individuals' evaluations of local officials in China. We conduct a nationwide vignette experiment with 5527 citizens, and find that the corruption–competence tradeoff exists and is hierarchical. Respondents prefer competent but corrupt low-level officials over those who are honest but incompetent, but this relative preference vanishes when they evaluate high-level local officials. Our interviews reveal that proximity to citizens and position in the power hierarchy primarily drive citizens' sophisticated assessments of officials at different levels.

Elected representatives have more means of public-facing communication at their disposal than ever before. Several studies examine how representatives use individual mediums, but we lack a baseline understanding of legislators’ relative use patterns across platforms. Using a novel data set of the four most widely used forms of written, constituent-facing communication (press releases, e-newsletters, Facebook posts, and Twitter tweets) by members of the US House of Representatives in the 114th (2015–2017), 115th (2017–2019), and 116th (2019–2021) Congresses, we generate a baseline understanding of how representatives communicate across mediums. Our analyses show that institutional, legislator, and district characteristics correspond with differential use of mediums. These findings underscore why medium choice matters, clarifying how a researcher's choice of mediums might amplify the voices of certain legislators and dampen those of others. In addition, they provide guidance to other researchers on how to select the medium(s) that best correspond with different research aims.

This research note investigates how mainstream party strategies affect the success of radical right parties (RRPs). It is a widespread view that mainstream party accommodation of radical right core issue positions would reduce the radical right's success. Empirical evidence for this claim, however, remains inconclusive. Using party level data as well as micro-level voter transitions between mainstream and RRPs, we re-evaluate the effectiveness of accommodative strategies and also test whether they work contingent on specific conditions, e.g., the newness of radical right challengers or the existence of a cordon sanitaire. We do not find any evidence that accommodative strategies reduce radical right support. If anything, our results suggest that they lead to more voters defecting to the radical right. Our findings have important implications for the study of multi-party competition as they challenge what has become a core assumption of this literature: that accommodative strategies reduce niche party success.

Do agencies implement the president's particularistic goals uniformly? This paper clarifies the presidential particularism literature by explicitly considering the mechanism through which the president pursues their policy goals: executive agencies. The constellation of bureaucratic agencies responsible for allocating grants plays a key role in facilitating or frustrating presidential policy priorities. Using a dataset of 21 agencies over 14 years, I find that only agencies ideologically proximate to the president engage in particularism benefiting the president. I find no evidence that politicization influences agency implementation of particularism. Critically, the moderating effect of the bureaucracy on particularism only occurs for distributive programs over which agencies have discretion. When disbursing formula grants written by Congress but administered by the bureaucracy with little or no discretion, ideological distance between agencies and presidents has no effect on particularism.

Is terrorism effective as a tool of political influence? In particular, do terrorists succeed in affecting their targets’ attitudes, and how long does the effect last? Existing research unfortunately is either limited to small samples or does not address two main difficulties: issues of endogeneity and the inability to assess the duration of the effect. Here, we first exploit the exogeneity to the selection process of the success or failure of an attack as an identification mechanism. Second, we take advantage of the random allocation of survey respondents to interview times to estimate the duration of the impact of terrorist events on attitudes. Using survey data from 30 European democracies between 2002 and 2017, we find first that terrorism affects people's reported life satisfaction and happiness—a proxy for the cost of terrorism in terms of utility. However, we also find that terrorist attacks do not affect respondents’ attitude toward their government, institutions, or immigrants. This suggests that terrorism is ineffective at translating discontent into political pressure. Importantly, we also find that all effects disappear within less than two weeks.

Political actors often interact spatially, and move around. However, with a few exceptions, existing political research has analyzed spatial dependence among actors with fixed geographic locations. Focusing on fixated geographic units prevents us from probing dependencies in spatial interaction between spatially dynamic actors, which are common in some areas of political science, such as sub-national conflict studies. In this note, we propose a method to account for spatial dependence in dyadic interactions between moving actors. Our method uses the spatiotemporal histories of dyadic interactions to project locations of future interactions—projected actor locations (PALs). PALs can, in turn, be used to model the likelihood of future dyadic interactions. In a replication and extension of a recent study of subnational conflict, we find that using PALs improves the predictive performance of the model and indicates that there is a clear relationship between actors’ past conflict locations and the likelihood of future conflicts.

Research from the United States has shown that the 9/11 terrorist attacks activated individuals’ ethnocentric predispositions to structure public opinion toward several political and social issues. Beyond this overall finding, several aspects of the activation hypothesis remain unexplored, including its geographical and substantive scope. Using the quasi-random timing of terrorist attacks during the collection of the 2016 GGSS, we demonstrate the terrorism-induced activation of ethnocentrism in Germany. Specifically, a cascade of terrorist attacks involving immigrants in the summer of 2016 activated ethnocentrism among native Germans to predict (lower) support for civil liberties relative to security concerns after its influence had been absent just a month before. Further, we show that the activation of ethnocentrism holds up in a series of robustness checks and is not explained by alternative factors, including other predispositions.

In this research note, we examine how Hong Kong voters respond to police violence in the recent social movement. We use causal forests, a machine learning algorithm, to estimate the impact of tear gas usage specific to each constituency. Based on the 2019 District Council Election outcome, we find that there is heterogeneity in the effect of state coercion on the vote share of pro-democracy candidates, depending on many socioeconomic characteristics of the constituency. The results imply that economic concerns still matter in the struggle to obtain democracy: citizens who sense economic insecurity in social unrest show less disapproval of state violence.

Oil discoveries, paired with delays in production, have created a new phenomenon: sustained post-discovery, pre-production periods. While research on the resource curse has debated the effects of oil on governance and conflict, less is known about the political effects of oil discoveries absent production. Using comprehensive electoral data from Uganda and a difference-in-differences design with heterogeneous effects, we show that oil discoveries increased electoral support for the incumbent chief executive in localities proximate to discoveries, even prior to production. Moreover, the biggest effects occurred in localities that were historically most electorally competitive. Overall, we show that the political effects of oil discoveries vary subnationally depending on local political context and prior to production, with important implications for understanding the roots of the political and conflict curses.

In light of important political events that go beyond the nation state (e.g., migration, climate change, and the coronavirus pandemic), domestic politicians are increasingly pressured to scrutinize and speak out on European policy-making. This creates a potential trade-off between allocating effort to domestic and supranational affairs, respectively. We examine how citizens perceive legislator involvement in European Union (EU) politics with a pre-registered conjoint experiment in Germany. Our results show that Members of Parliament (MPs) are not disadvantaged when allocating effort to European affairs as compared to local and national affairs. In addition, voters tend to prefer MPs who engage in EU policy reform over those who do not. As demand for legislator involvement in European politics is on the rise, we provide empirical evidence that MPs can fulfill this demand without being disadvantaged by the electorate.

Extensive research on gender and politics indicates that women legislators are more likely to serve on committees and sponsor bills related to so-called “women's issues.” However, it remains unclear whether this empirical regularity is driven by district preferences, differences in legislator backgrounds, or because gendered political processes shape and constrain the choices available to women once they are elected. We introduce expansive new data on over 25,000 US state legislators and an empirical strategy to causally isolate the different channels that might explain these gendered differences in legislator behavior. After accounting for district preferences with a difference-in-differences design and for candidate backgrounds via campaign fundraising data, we find that women are still more likely to serve on women's issues committees, although the gender gap in bill sponsorship decreases. These results shed new light on the mechanisms that lead men and women to focus on different policy areas as legislators.

Substantial evidence exists that members of the US Congress vary in their lawmaking effectiveness. Less known, however, is whether constituents are sufficiently informed and inclined to hold their representatives accountable, based on their effectiveness. We conduct two separate survey experiments, informing some constituents about lawmakers' effectiveness and comparing their responses to those with the baseline level of information. We find that voters demonstrate little knowledge of their elected officials' lawmaking effectiveness. When presented with objective and credible information about lawmaking effectiveness, however, respondents express greater approval of more effective lawmakers. Effects are strongest among ideological moderates, but are even pronounced among partisans, who approve of effective representatives of the opposing party, and disapprove of ineffective representatives from their own party.

Previous research finds that policy complexity affects important political processes including legislative delegation and policy diffusion. However, policy complexity is not directly observable and the search for a reasonable proxy constitutes a major challenge for scholars. This research note presents a concise and measurable definition of complex policy based on two aspects: a policy's textual sophistication and its ties to other rules and regulations. Using crowdsourcing and a pairwise comparison framework it is shown that the proposed defining features are crucial for humans’ understanding of policy text. The proposed definition is then operationalized using a large corpus of European Union rules and is shown to outperform alternative operationalizations of policy complexity in predicting the level of legislative delegation.

Inequalities in voter participation between groups of the population pose a problem for democratic representation. We use administrative data on 6.7 million registered voters to show that a previously-ignored characteristic of voters—access to a personal automobile—creates large disparities in in-person voting rates. Lack of access to a car depresses election day voter turnout by substantively large amounts across a variety of fixed-effects models that account for other environmental and voter characteristics. Car access creates the largest hindrance to voting for those people who live farther from the polls. These effects do not appear for absentee voting, suggesting a simple policy solution to solve large disparities in political participation. This study contributes to the theoretic understanding of political participation as well as the impact of potential policy reforms to solve participatory gaps.

High temperatures have been linked to aggression and different forms of conflict in humans. We consider whether exposure to heat waves increases discriminatory behavior toward outgroups. Using data from two large-scale field experiments in Germany, we find a direct causal effect of exposure to heat shocks on discrimination in helping behavior. As temperature rises, German natives faced with a choice to provide help to strangers in every-day interactions help Muslim immigrants less than they do other German natives, while help rates toward natives are unaffected by temperature. This finding suggests that there may be a physiological basis for discriminatory behavior toward outgroups.
