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....

This paper examines whether a Northern firm prefers to export or to engage in FDI to serve the South. If the firm engages in FDI, its technology is imitated, and a Southern firm enters the market that may sell in both markets. The Northern firm may invest to prevent product piracy in the North....

We develop a structural framework that allows us to quantify the evolution of aggregate bilateral trade costs and markups over time. With minimal assumptions, we can disentangle aggregate markup and trade cost changes from observed changes in trade flows. We apply our method to trade data...

This paper examines the forms, goals, and results of price discrimination. It reviews various economic analyses and critiques of the three Pigovian types of price discrimination. It observes that economists' traditional concern with aggregate welfare has not, until recently, been accompanied by...

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...

The arm's length principle states that the transfer price between two associated enterprises should be the price that would be paid for similar goods in similar circumstances by unrelated parties dealing at arm's length with each other. This paper examines the effect of the arm's length...

To examine the impact of globalization on managerial compensation, we consider a matching model where firms compete both in the product market and in the managerial market. We show that globalization, that is, the simultaneous integration of product markets and managerial pools, leads to an...

This paper presents an industry equilibrium model where firms have a choice to engage in corporate social responsibility (CSR) activities. We model CSR as an investment to increase product differentiation that allows firms to benefit from higher profit margins. The model predicts that CSR...
