October 2017Vertical Integration, Supplier Behavior, and Quality Upgrading among Exporters
with Christopher Hansman, Jonas Hjort, Matthieu Teachout: w23949
We study the relationship between exporters' organizational structure and output quality. If only input quantity is observable, theory predicts that vertical integration may be necessary to incentivize suppliers to increase input quality. Using data on suppliers' behavior, supplier ownership, supply transactions, and manufacturers' output by quality grade and exports from the Peruvian fishmeal industry, we show the following. After integrating with the plant being supplied and losing access to alternative pay-per-kilo buyers, suppliers take more quality-increasing and less quantity-increasing actions. Integration consequently causally increases output quality, and manufacturers integrate suppliers when facing high relative demand for high quality grades.
May 2016Compulsory Voting, Turnout, and Government Spending: Evidence from Austria
with Mitchell Hoffman, María Lombardi: w22221
We study a unique quasi-experiment in Austria, where compulsory voting laws are changed across Austria's nine states at different times. Analyzing state and national elections from 1949-2010, we show that compulsory voting laws with weakly enforced fines increase turnout by roughly 10 percentage points. However, we find no evidence that this change in turnout affected government spending patterns (in levels or composition) or electoral outcomes. Individual-level data on turnout and political preferences suggest these results occur because individuals swayed to vote due to compulsory voting are more likely to be non-partisan, have low interest in politics, and be uninformed.

October 2013Transportation Choices and the Value of Statistical Life
with Edward Miguel: w19494
This paper exploits an unusual transportation setting to estimate the value of a statistical life (VSL). We estimate the trade-offs individuals are willing to make between mortality risk and cost as they travel to and from the international airport in Sierra Leone (which is separated from the capital Freetown by a body of water), and choose from among multiple transport options - namely, ferry, helicopter, hovercraft, and water taxi. The setting and original dataset allow us to address some typical omitted variable concerns, and to compare VSL estimates for travelers from different countries, all facing the same choice situation. The average VSL estimate for African travelers in the sample is US$577,000 compared to US$924,000 for non-African travelers. Individual job earnings can largely a...
