"Aggressive deregulation of the mortgage market in the early 1980s triggered innovations that greatly reduced the required home equity of U.S. households. This allowed households to cash-out a large part of accumulated equity, which equaled 71 percent of GDP in 1982. A borrowing surge followed:...

The consumption of households with liquid financial assets responds much more to transitory income shocks than the permanent-income hypothesis predicts. That is, middle class households with assets act as if they face liquidity constraints. This paper addresses this puzzling observation with a...

"Market innovations following the financial reforms of the early 1980's relaxed collateral constraints on households' borrowing. This paper examines the implications of this development for macroeconomic volatility. We combine collateral constraints on households with heterogeneity of thrift in...

"This paper characterizes the labor supply and borrowing of a household facing collateral requirements that limit its debt and compel it to accumulate equity in its durable goods stock. The household's discount rate exceeds the market rate of interest, so it would otherwise finance increased...

The financial labor supply accelerator links hours worked to minimum down payments for durable good purchases. When these constrain a household's debt, a persistent wage increase generates a liquidity shortage. This limits the income effect, so hours worked grow. The mechanism generates a...

"This paper evaluates the simplifying assumption that producers compete in a large market without substantial strategic interactions using nonparametric regressions of producers' choices on market size. With such atomistic competition, increasing the number of consumers leaves the distributions...

This paper considers monetary and fiscal policy when tangible assets can be accumulated after shocks that increase desired savings, like Joseph's biblical prophecy of seven fat years followed by seven lean years. The model's flexible-price allocation mimics Joseph's saving to smooth consumption....

This paper summarizes interviews from 1998 with 590 individuals trying to create a business centered around five questions: “Who are you?”, “What are you trying to accomplish?”, “What have you and others put into the business?”, “What have you accomplished?”, “What remains to...

"This paper extends the static analysis of oligopoly structure into an infinite- horizon setting with sunk costs and demand uncertainty. The observation that exit rates decline with firm age motivates the assumption of last-in first- out dynamics: An entrant expects to produce no longer than any...

"This paper considers the effects of raising the cost of entry for potential competitors on infinite-horizon Markov- perfect industry dynamics with ongoing demand uncertainty. All entrants serving the model industry incur sunk costs, and exit avoids future fixed costs. We focus on the unique...
