We develop an heterogeneous agent model of consumption and health choices in order to estimate the effect of heath status in the marginal utility of consumption. We use micro data from the HRS, PSID, and CEX to identify the parameters of interest from the observed consumption growth for...

We develop a theory on the joint dynamics of labor share and technology at the business cycle frequency. Our main motivating fact is the overshooting property of the labor share: After a positive technology shock, the share of output that corresponds to labor falls temporarily but it quickly...

This paper develops a new quantitative theory of long-term unsecured credit contracts. Households can default and can switch credit lines. Banks can change the credit limit at any time, but must commit to the interest rate or not depending on the regulatory setting. Without commitment, the...

Between the mid 1970's and the beginning of the 2000's the share of single females grew dramatically in the U.S. (from 21% to 32%). So did the share of single mothers (from 10% to 14%). At the same time relative wages within and between sexes underwent huge changes. In this paper we measure the...

consequently, have different redistributional properties which is what we explore in this paper. For Canada, which has a positive net asset position with respect to the rest of the world in Canadian dollar-denominated claims, we show that the magnitude of the effects of an unexpected price level...

We explore the effects of financial shocks in heterogeneous agent economies with aggregate savings and with frictions in some consumption markets, where demand contributes to productivity. Households of various wealth and earnings levels search for goods at different intensities and pay...

In this paper, we use data of life insurance holdings by age, sex, and marital status to infer how individuals value consumption in different demographic stages. Essentially, we use revealed preference to estimate equivalence scales and altruism simultaneously in the context of a fully specified...

We show that a theory of earnings and wealth inequality, based on the optimal choices of ex ante identical households that face uninsured idiosyncratic shocks to their endowments of efficiency labor units, accounts for the U.S. earnings and wealth inequality almost exactly.

The authors study, theoretically and quantitatively, the general equilibrium of an economy in which households smooth consumption by means of both a riskless asset and unsecured loans with the option to default. The default option resembles a bankruptcy filing under Chapter 7 of the U.S....
