Models featuring increasing returns to scale in at least one factor of production have been used to study two separate phenomena: (1) multiplicity of self-fulfilling rational expectations equilibria (i.e. sunspots), and (2) production schedules that optimally feature bunching. We show in a...

The effect of credit market competition on borrower default is theoretically ambiguous, because the quantity of credit supplied may rise or fall following an increase in competition. We investigate empirically the relationship between credit market competition, lending to households, and...

Mutual funds have become an important intermediary between households and financial markets, especially the equity market. About half of all households have a mutual fund account, and mutual funds hold about one-fifth of household financial assets. Because households have favored equity...

Fannie Mae and Freddie Mac are government-sponsored enterprises (GSEs) that purchase mortgages and issue mortgage-backed securities (MBS). In addition, the GSEs are active participants in the primary and secondary mortgage markets on behalf of their own portfolios of MBS. Because these...

Consumer bankruptcy laws, which vary across states and over time, permit debtors to keep assets below a statutory exemption while debts are forgiven. High exemptions distort household portfolio decisions and tempt households to default on debts, but they also provide a crude form of consumption...

Governments use monetary policies to counteract the effects of financial crises. In this paper we examine the subsidy that such "safety net" policies provide to the banking industry. Using a model of uncertainty-driven financial crises, we show that any monetary policy designed to maintain risky...

I study the effect of improved financial intermediation on the process of capital accumulation by augmenting a standard model with a general contract space. With the extra contracts, intermediaries endogenously begin using ROSCAs, or Rotating Savings and Credit Associations. These contracts...

The return on assets depends on the joint behavior of all savers; if all sell the asset simultaneously, then there will be a financial "Armageddon." We assume that risk-neutral savers' information about aggregate investment is too vague to form precise probability estimates, so they have...

The Community Reinvestment Act (CRA) encourages lenders to make mortgage loans to certain classes of borrowers. However, the law does not apply to all lenders, and lenders do not necessarily receive credit for all loans made to borrowers of a particular class. We use this variation to test...

I test the credit-market effects of housing wealth shocks by estimating the consumption elasticity of house price shocks among households in different age quintiles. Younger households face faster expected income growth and hence would like to borrow more than older households. I estimate...
