We propose a stylized monopolistic competition model of international trade where firms differ with respect to the expected economic lifetime of their innovations. Upon entry, they receive a commonly observed signal which is updated over time. Jointly with partial irreversibility of investment,...

We develop a heterogeneous-firms model with trade in goods, labor mobility and credit constraints due to moral hazard. Mitigating financial frictions reduces the incentive of high-skilled workers to migrate to one region such that an unequal distribution of industrial activity becomes less...

Firms facing uncertainty about demand at the time of production expose their shareholders to volatile returns. Risk-averse investors trading multiple assets will favor stocks that tend to yield high returns in bad times, that is, when marginal utility of consumption is high. In this paper, I...

In this paper we analyze the impact of public export credit guarantees on firms' exports. Earlier studies show that export credit guarantees stimulate exports, employment, and value added. Furthermore, there is evidence at the aggregate level that financial market imperfections are key to...

When countries open their financial sectors, foreign-owned banks appear to bring superior efficiency to their host markets but also charge higher markups on borrowed funds than their domestically owned rivals, with unknown impacts on interest rates and welfare. Using heterogeneous, imperfectly...

The model and related empirical examination in this paper explain why previous studies document both positive and negative correlations between exchange rate volatility and observed levels of foreign direct investment. Using a simple model of cross-border mergers and acquisitions, it argues that...
