For smart phones, most apps and websites use a simplification version of the personal computer version. To the best of our knowledge, we are the first to consider the functionality of apps. We show when the equilibrium functionality is efficient, excessive or insufficient. For the case of...

By combining two large data sets (on international trade flows and cross-border mergers and acquisitions - M&As), we test two implications of Neary’s (2003, 2007) general oligopolistic equilibrium (GOLE) model (incorporating strategic interaction between firms in a general equilibrium...

We build a model of tacit collusion between firms that operate in multiple markets to study the effects of trade costs. A key feature of the model is that cartel discipline is endogenous. Thus, markets that appear segmented are strategically linked via the incentive compatibility constraint....

Despite a variety of measures taken by high tax countries, the international fight against tax havens so far remained rather ineffective. This paper introduces lobbying as a possible explanation for this observation. I analyze the international fight against tax havens in a two country model in...

By combining two large data sets (on international trade flows and on mergers and acquisitions - M&As), we are able to test two implications of Neary's (2003, 2004a) recent theoretical work. Analyzing M&As in a General Oligopolistic Equilibrium (GOLE) model incorporating strategic interaction...

Do international trade and technological change influence how firms create incentives for human capital? I present a model that incorporates agency problems into a framework with firm heterogeneity and human capital. My model indicates that trade liberalizations and skill-biased technological...
