Money market funds (MMFs) are popular around the world, with over $9 trillion in assets under management globally. From their origins in the 1970s, MMFs have operated in a niche between the capital markets and the banking system, as investment funds that offer private money-like assets with...

During times of economic crises, the public policy response is to abandon basic economic thinking and engage in ‘emergency economic’ policies. We explore how the current financial crisis was in part caused by previous emergency economic measures. We then investigate the theoretical...

This paper provides a quantitative account of the tri-party repo market during the recent financial crisis. Using data from July 2008 to January 2010, we show that the level of haircuts and the amount of funding were surprisingly stable in this market. The stability of the haircuts contrasts...

This paper develops an infinite-horizon model of financial institutions that borrow short-term and invest in long-term assets that can be traded in frictionless markets. Because these financial intermediaries perform maturity transformation, they are subject to potential runs. We derive distinct...

The recent financial crisis has shown that short-term collateralized borrowing may be a highly unstable source of funds in times of stress. The present paper develops a dynamic equilibrium model and analyzes under what conditions such instability can be a consequence of market-wide changes in...

We build a model in which financial intermediaries provide insurance to households against a liquidity shock. Households can also invest directly on a financial market if they pay a cost. In equilibrium, the ability of intermediaries to share risk is constrained by the market. This can be...

In many models of financial intermediation, markets reduce welfare because they limit the amount of risk-sharing intermediaries can offer. In this paper we study a model in which markets also promote investment in a productive technology. A trade-off between risk sharing and growth arises...
