|May 2018||The other 1%: Class Leavening, Contamination and Voting for Redistribution|
with Lars Lefgren, Olga Stoddard: w24617
We perform an experiment to measure how changes in the effort exerted by a small fraction of a low-reward group affect the willingness of the high-reward group to vote for redistributive taxation. We find that a substantial fraction of high reward subjects vote in favor of greater redistribution when a very small fraction of high-effort individuals is added to a pool of otherwise low-effort poor. Contaminating a group of high-effort poor with a small number of low-effort individuals causes the most generous rich subjects to vote for less redistribution. These results suggest that anecdotes about the deservedness of a small group of transfer recipients may be effective in changing support for redistribution. We find large gender differences in the results. Relative to men, women respond ...
|June 2008||The Persistence of Teacher-Induced Learning Gains|
with Brian A. Jacob, Lars Lefgren: w14065
Educational interventions are often narrowly targeted and temporary, and evaluations often focus on the short-run impacts of the intervention. Insofar as the positive effects of educational interventions fadeout over time, however, such assessments may be misleading. In this paper, we develop a simple statistical framework to empirically assess the persistence of treatment effects in education. To begin, we present a simple model of student learning that incorporates permanent as well as transitory learning gains. Using this model, we demonstrate how the parameter of interest - the persistence of a particular measurable education input - can be recovered via instrumental variables as a particular local average treatment effect. We initially motivate this strategy in the context of tea...
