We develop a life-cycle model of the labor market in which different worker-firm matches have different quality and the assignment of the right workers to the right firms is time consuming because of search and learning frictions. The rate at which workers move between employment, employment and...

In the 2001 U.S. Survey of Consumer Finances (SCF), 27% of households report simultaneously revolving significant credit card debt and holding sizeable amounts of liquid assets. These consumers report paying, on average, a 14% interest rate on their debt, while earning only 1 or 2% on their...

In the 2001 U.S. Survey of Consumer Finances, 27% of households report simultaneously revolving significant credit card debt and holding sizeable amounts of low-return liquid assets; this is known as the "credit card debt puzzle". In this article, I quantitatively evaluate the role of liquidity...

We investigate quantitative implications of precautionary demand for money for business cycle dynamics of velocity and other nominal aggregates. Accounting for such dynamics is a standing challenge in monetary macroeconomics: standard business cycle models that have incorporated money have...

Precautionary demand for money is significant in the data, and may have important implications for business-cycle dynamics of velocity and other nominal aggregates. Accounting for such dynamics is a standing challenge in monetary macroeconomics: standard business-cycle models that have...

The authors study empirically and theoretically the patterns of home equity withdrawal among retirees, using a model in which retirees are able to own or rent a home, save, and borrow against home equity, in the face of idiosyncratic risks concerning mortality, health, medical expenditures, and...

the model account for relevant properties of the data, but not very significantly. The biggest quantitative potential for search frictions in this setting appears to be in the dynamic implications they generate for inventories and markups in the retail sector. Assessment of this potential is in...
