We identify the causal effect of trade-integration with China and Eastern Europe on voting in Germany from 1987 to 2009. Looking at the entire political spectrum, we find that only extreme-right parties respond significantly to trade integration. Their vote share increases with import competition and decreases with export access opportunities. We unpack mechanisms using reduced form evidence and a causal mediation analysis. Two-thirds of the total effect of trade integration on voting appears to be driven by observable labor market adjustments, primarily changes in manufacturing employment. These results are mirrored in an individual-level analysis in the German Socioeconomic Panel.
Studying Native American reservations, and their historical formation, I find that their forced integration of autonomous polities into a system of shared governance had large negative long‐run consequences, even though the affected people were ethnically and linguistically homogenous. Reservations that combined multiple sub‐tribal bands when they were formed are 30% poorer today, even when conditioning on pre‐reservation political traditions. The results hold with tribe fixed effects, identifying only off within‐tribe variation across reservations. I also provide estimates from an instrumental variable strategy based on historical mining rushes that led to exogenously more centralized reservations. Data on the timing of economic divergence and on contemporary political conflict suggest that the primary mechanism runs from persistent social divisions through the quality of local governance to the local economic environment.

Terms of use: Documents in AbstractIt is often the case that an endogenous treatment variable causally affects an intermediate variable that in turn causally affects a final outcome. Using an Instrumental Variable (IV) identifies the causal effect of the endogenous treatment on both the intermediate and the final outcome variable, but not the extent to which the intermediate variable affects the final outcome. We present a new testable framework in which a single IV suffices to also estimate the causal effect of the intermediate variable on the final outcome. We use this framework to investigate to what extent German voters responded to the labor market turmoil caused by increasing trade with low-wage manufacturing countries. We first establish that import competition increased voters' support for only extreme (right) parties. We then decompose this populist 'total effect' into a 'mediated effect' running through labor market adjustments and a 'direct effect' of trade exposure on voting behavior. We find the total consists of a large populist effect driven by labor markets and a relatively smaller but moderating direct effect. Our approach provides a template that may be useful in a broad range of empirical applications studying causal mechanisms in observational data.
In this article, we describe the use of ivmediate, a new command to estimate causal mediation effects in instrumental-variables settings using the framework developed by Dippel et al. (2020, unpublished manuscript). ivmediate allows estimation of a treatment effect and the share of this effect that can be attributed to a mediator variable. While both treatment and mediator can be potentially endogenous, a single instrument suffices to identify both the causal treatment and the mediation effects.
We investigate economic causes of the rising support of populist parties in industrialized countries. Looking at Germany, we find that exposure to imports from low wage countries increases the support for nationalist parties between 1987–2009, while increasing exports have the opposite effect. The net effect translates into increasing support of the right-populist AfD after its emergence in 2013. Individual data from the German Socioeconomic Panel reveal that low-skilled manufacturing workers’ political preferences are most responsive to trade exposure. Using a novel approach to causal mediation analysis, we identify trade-induced labor market adjustments as economic mechanism causing the voting response to international trade.
