International Capital Flows And Credit Market Imperfections: A Tale Of Two Frictions
The financial crisis of 2007-08 has underscored the importance of adverse selection in financial markets. This friction has been mostly neglected by macroeconomic models of financial imperfections, however, which have focused almost exclusively on the effects of limited pledgeability. In this paper, the authors fill this gap by developing a standard growth model with adverse selection. Their main results are that, by fostering unproductive investment, adverse selection: leads to an increase in the economy's equilibrium interest rate, and; it generates a negative wedge between the marginal return to investment and the equilibrium interest rate. Under financial integration, they show how this translates into excessive capital inflows and endogenous cycles.
