Our general objective is to characterize the recent and well publicized diffusion of Twitter among politicians in the United States 111th House of Representatives. Ultimately, Barrack Obama, Facebook and peers matter when it comes to the propensity and speed of Twitter adoption. A basic analysis...

We study the early adoption of Twitter in the 111th House of Representatives. Our main objective is to determine whether successes of past adopters have the tendency to speed up Twitter adoption, where past success is defined as the average followers per Tweet (i.e. "Twitter clout") among all...

We study the early adoption of Twitter in the 111th House of Representatives. Our main objective is to determine whether successes of past adopters have the tendency to speed up Twitter adoption, where past success is defined as the average followers per Tweet - a common measure of "Twitter...

This paper offers a new identification strategy for disentangling structural state dependence from unobserved heterogeneity in preferences. Our strategy exploits market environments where there is a choice-consumption mismatch. We first demonstrate the effectiveness of our identification...

Under the context of a dynamic oligopoly model of entry and exit with two firms, we analytically derive a set of sufficient conditions for deterrence-motivated entry. In particular, the conceptual framework we present yields a set of testable hypotheses that can be conducted using inferred...

This paper presents a new decomposition approach for measuring deterrence motives in dynamic oligopoly games. Our approach yields a scale-free and interpretable measure of deterrence motives that informs researchers about the proportion for which deterrence motives account of all entry motives....

We study the impact of premium adoption on mHealth user engagement and its weight loss effectiveness. Our empirical analysis uses unique panel data from a popular mobile food and exercise tracking app. To estimate the causal effect of premium adoption we use a propensity score matching method....
