March 2017Instrumental Variables and Causal Mechanisms: Unpacking The Effect of Trade on Workers and Voters
with Robert Gold, Stephan Heblich, Rodrigo Pinto: w23209
We investigate the impact of import exposure on regional labor markets and voting behavior. Using a standard IV model, we find in German data from 1987–2009 that import exposure caused both significant labor market adjustments and increasing support for extreme-right parties. Our focus is on the question that naturally follows: to what extent was the effect of import exposure on labor markets responsible for the political response? The standard IV model cannot answer this question. We propose a new framework for mediation analysis in IV settings that can, while making minimal additional assumptions on the causal relations between the unobserved variables. We find that the effect of import exposure on voting that is mediated by labor market adjustments is larger than the total effect of imp...
October 2016Elite Identity and Political Accountability: A Tale of Ten Islands
with Jean-Paul Carvalho: w22777
This paper examines the relationship between elite identity and political outcomes from a theoretical and empirical perspective. Elite members with distinct economic and social identities vote for or against an extractive policy, which benefits them at the expense of the citizenry. Voting is disciplined by the threat of citizen revolt, with some elite members being more accountable than others. The relationship between elite identity and political accountability is complex and non-monotonic. As their share in the elite grows, accountable elite members are more likely to vote for extractive policies. When the elite becomes too accountable as a whole, elite members may pursue extractive policies by altering the institutional framework. The model is grounded in an empirical exploration of ten...
December 2015Globalization and Its (Dis-)Content: Trade Shocks and Voting Behavior
with Robert Gold, Stephan Heblich: w21812
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.
February 2015Outside Options, Coercion, and Wages: Removing the Sugar Coating
with Avner Greif, Daniel Trefler: w20958
In economies with a large informal sector firms can increase profits by reducing workers’ outside options in that informal sector. We formalize this idea in a simple model of an agricultural economy with plantation owners who lobby the government to enact coercive policies—e.g. the eviction and incarceration of squatting small-hold farmers—that reduce the value to working outside the formal sector. Using unique data for 14 British West Indies ‘sugar islands’ from the year of slave emancipation in 1838 until 1913, we examine the impact of plantation owners’ power on wages and coercion-related incarceration. To gain identification, we utilize exogenous variation in the ease with which smallholders could evade the plantation system in the different islands over time. Where evading the plantat...
