Using a new model of heterogeneous, imperfectly competitive lenders and a simple search process, we show how endogenous markups (the net interest margin commonly used to proxy lending-to-deposit rate spreads) can increase with FDI while the rates banks charge to borrowers remain largely...

Using a model with upfront sunk costs, heterogeneous firms, and endogenous exchange rates, this paper demonstrates theoretically that volatility in fundamental variables such as the nominal interest rate that drive exchange rate volatility can simultaneously impact the entry behavior of...

Stephen Hymer (1960, 1976) argues that a desire to increase market power is a strong motive for foreign takeovers. Yet the market-power motive for FDI flows has been largely unexplored in the modern theory of heterogeneous firms. This paper shows that foreign direct investment can increase...

Can allowing foreign participation in the banking sector increase real output, despite the imperfectly competitive nature of the industry? Using a new model of heterogeneous, imperfectly competitive lenders and a simple search process, we show how endogenous markups (the net interest margin...

We show that an ostensibly disparate set of stylized facts regarding firm pricing behavior can arise in a Ricardian model with Bertrand competition. Generalizing the Bernard, Eaton, Jenson, and Kortum (2003) model allows firms' markups over marginal cost to fall under trade liberalization, but...

While bank lending contracts during the typical recession, liquidity in bond markets may not.

Does the mere presence of big banks affect macroeconomic outcomes? In this paper, we develop a theory of granularity (Gabaix, 2011) for the banking sector, introducing Bertrand competition and heterogeneous banks charging variable markups. Using this framework, we show conditions under which...

The purpose of this paper is to understand the effects of endogenous markups and trade costs on the pricing behavior of exporters when firms are heterogeneous in productivity. Using new analytical distributions for markups under Bertrand competition, we uncover Ricardian patterns of export...
