|May 2019||Pay Transparency and the Gender Gap|
with Michael Baker, Kory Kroft, Alexandre Mas, Derek Messacar: w25834
We examine the impact of public sector salary disclosure laws on university faculty salaries in Canada. The laws, which enable public access to the salaries of individual faculty if they exceed specified thresholds, were introduced in different provinces at different points in time. Using detailed administrative data covering the universe of faculty in Canada and an event-study research design, we document three key findings. First, the disclosure laws reduced salaries on average. Second, the laws reduced the gender pay gap between men and women. Third, the closure of the gender gap is primarily in universities where faculty are unionized.

with Brian Knight: w20681
In this paper, we investigate political communications in social networks characterized both by homophily–a tendency to associate with similar individuals–and group size. To generate testable hypotheses, we develop a simple theory of information diffusion in social networks with homophily and two groups: conservatives and liberals. The model predicts that, with homophily, members of the majority group have more network connections and are exposed to more information than the minority group. We also use the model to show that, with homophily and a tendency to produce like-minded information, groups are disproportionately exposed to like-minded information and the information reaches like-minded individuals more quickly than it reaches individuals of opposing ideologies. To test the hypothes...
