If countries anticipate Bertrand competition in tax rates, they may expend effort that makes some of their tax payers less mobile or increases the mobility of tax payers elsewhere. I provide piecemeal evidence on what activities countries use. I analyse how such activities interact with Bertrand...

In this paper, we analyse the effects of a unilateral change in an emissions tax in a model of international trade with heterogeneous firms. We find a positive effect of tighter environmental policy on average productivity in the reforming country through reallocation of labour towards exporting...

This paper examines the link between a firm's ownership of productive assets and its choice of foreign-market entry strategy. We find that, controlling for industry- and country-specific characteristics, the most productive firms (i.e., those owning the most assets) will enter through greenfield...

We analyze spying out a rival’s price in a Bertrand market game with incomplete information. Spying transforms a simultaneous into a robust sequential moves game. We provide conditions for profitable espionage. The spied at firm may attempt to immunize against spying by delaying its pricing...

We study an infinitely repeated oligopoly game in which firms compete on quantity and one of them is capacity constrained. We show that collusion sustainability is non-monotonic in the size of the capacity constrained firm, which has little incentive to deviate from a cartel. We also present...

Government investment in university research results in greater output and impact. To better capture economic benefits stemming from university research, governments have developed funding programs specifically targeting university-industry collaboration. However, little is known about the...

We investigate the dimensions through which R&D spillovers are propagated across firms via cooperation through Research Joint Ventures (RJVs). We build on the framework developed by Bloom et al. (2013) which considers the opposing effects of technology spillovers and product market rivalry, and...

We examine friendships and study partnerships among university students over several years. At the aggregate level, connections increase over time, but homophily on gender and ethnicity is relatively constant across time, university residences, and different network layers. At the individual...
