I address the controversy over whether the financial services industry is "too big." We should be asking whether the finance industry is functioning properly instead. The facts suggest that demand for financial services increased, perhaps temporarily, rather than suggesting a changing distortion...

This paper introduces a framework for analyzing the role of financial factors as a source of instability in small open economies. Our basic model is a dynamic open economy model with a tradeable good produced with capital and a country-specific factor. We also assume that firms face credit...

This paper provides an overview of the complex conceptual and practical challenges that emerging market economies face as they attempt to reform their frameworks for financial regulation. These economies are striving to balance the quest for financial stability with the imperatives of financial...

Financial institutions may be vulnerable to predatory short selling. When the stock of a financial institution is shorted aggressively, leverage constraints imposed by short-term creditors can force the institution to liquidate long-term investments at fire sale prices. For financial...

Nonbank lenders have been playing an increasing role in supplying debt, especially after the Great Recession. How important are the distortions in the greater regulation of banks that differentially limit risk-taking across alternative providers of credit? How might the growing role of nonbanks...

I characterize the optimal financial regulation policy in an economy where financial intermediaries trade capital assets on behalf of households, but must retain an equity stake to align incentives. Financial regulation is necessary because intermediaries cannot be excluded from privately...

The paper provides an overview of cryptocurrencies and decentralized finance. The discussion lays out potential benefits and challenges of the new system and presents a comparison to the traditional system of financial intermediation. Our analysis highlights that while the DeFi architecture...

This paper explores the behavior of the U.S. economy during the interwar period from the perspective of a model in which the existence of non-convexities in the intermediation process gives rise to a multiplicity of equilibria. The resulting indeterminancy is resolved through a sunspot process...

This paper investigates the quantitative implications of two business cycle models in which aggregate fluctuations arise in response to variations in the process of financial intermediation. In the first, fundamental shocks in the capital accumulation process lead to fluctuations in the real...

The principal rationales that give rise to financial intermediation are benefits of size and specialization, the diversification of specific asset risks, and the pooling of even broader classes of risk. Each is a significant factor in accounting for the U.S. economy's reliance on intermediation....
