If borrowing capacity of indebted households is tied to the value of their home, house prices should enter a correctly specified aggregate Euler equation for consumption. I develop a simple two-agent, dynamic general equilibrium model in which home (collateral) values affect debt capacity and...

The weight of the average American adult male and female has increased by 16 and 14 pounds respectively and obesity rates have doubled since the early 1960s. Recent studies show these changes in weight can be attributed to the dramatic rise in the consumption of food away from home. We...

Entrepreneurs often face undiversifiable idiosyncratic risks from their business investments. Motivated by this observation, we extend the standard real options approach to investment to an incomplete markets environment and analyze the joint decisions of business investments, consumption-saving...

This paper investigates the role of discount rate heterogeneity for wealth inequality. The key idea is to infer the distribution of preference parameters from the observed age profile of wealth inequality. The contribution of preference heterogeneity to wealth inequality can then be measured...

A central puzzle for asset pricing theory is that stock prices are much more volatile than corporate dividends. One possible resolution is to modify standard models by introducing stochastic discount factors that induce large variation in prices for relatively smooth sequences of dividends. But...

Detailed macroeconomic data to accompany the article in the Review of Economic Dynamics

Using US quarterly post-war data, this paper documents the existence of two common trends among non-housing non durable and housing consumption, financial and real estate wealth, and labour income (a proxy for human wealth). The first equilibrium relationship reflects the stationarity of the...

Since 1975, the aggregate value of residential land has averaged approximately 90% of GDP and has recently risen to 125% of GDP. In this paper, I use a calibrated general-equilibrium model with idisyncratic labor productivity draws to attempt to measure the extent to which current tax policies,...
