What determines the technology that a country adopts? While many factors affect technological adoption, the efficiency of the country's financial system may also play a significant role. To address this question, a dynamic contract model is embedded into a general equilibrium setting with...

Many basic economic theories with perfectly functioning markets do not predict the existence of the vast number of microenterprises readily observed across the world. We put forward a model that illuminates why financial and managerial capital constraints may impede experimentation, and thus...

Technological progress is typically a result of trial-and-error research by competing firms. While some research paths lead to the innovation sought, others result in dead ends. Because firms benefit from their competitors working in the wrong direction, they do not reveal their dead-end...

This paper studies the effect of interest rates on investment in an environment where firms make irreversible investments and learn over time. In this setting, changes in the interest rate affect both the cost of capital and the cost of delaying investment. These two forces combine to generate...

This paper studies a simple model of experimentation and innovation. Our analysis suggests that patents may improve the allocation of resources by encouraging rapid experimentation and efficient ex post transfer of knowledge across firms. Each firm receives a private signal on the success...

Firms spend substantial resources on marketing and selling. Interpreting this as evidence of frictions in product markets, which require firms to spend resources on customer acquisition, this paper develops a search theoretic model of firm dynamics in frictional product markets. Introducing...

In this paper, we analyze the determinants of corporate saving in the form of changes in the stock of cash for 11 Asian economies using firm-level data from the Oriana Database for the 2002-2011 period. We find some evidence that cash flow has a positive impact on the change in the stock of...

This paper develops a theory of how angel and venture capital markets interact. Entrepreneurs first receive angel then venture capital funding. The two investor types are 'friends' in that they rely upon each other's investments. However, they are also 'foes', because at the later stage the...

This paper analyzes a model where investors use a credit rating to decide whether to finance a firm. The rating quality depends on the unobservable effort exerted by a credit rating agency (CRA). We analyze optimal compensation schemes for the CRA that differ depending on whether a social...

We evaluate the performance of limited partners' (LPs) private equity investments over time. Using a sample of 14,380 investments by 1,852 LPs in 1,250 buyout and venture funds started between 1991 and 2006, we find that the superior performance of endowment investors in the 1991-1998 period,...
