A skill-biased change in technology can account at once for the changes observed in a number of important variables of the US labour market between 1970 and 1990. These include the increasing inequality in wages, both between and within education groups, and the increase in unemployment at all...

This article studies the effects of demographics on the mix of tax rates on labor and capital. It uses a quantitative general-equilibrium, overlapping-generations model where tax rates are voted without past commitments in every period and characterized as a Markov equilibrium. In the United...

Credit cards offer a limit, rather than a specific loan size, at a pre-approved interest rate. This paper studies the determination of these credit limits jointly with default in the presence of one-period debt. I adapt the standard incomplete markets macroeconomic model of one-period unsecured...

A generalized rise in unemployment rates for both college and high-school graduates, a widening education wage premium, and a sharp increase in college education participation are characteristic features of the transformations observed in the U.S. labor market between 1970 and 1990. This paper...

This paper studies economies with complete markets where there is positive default on consumer debt. In a simple tractable two-period model, households can default partially, at a finite punishment cost, and competitive intermediaries price loans of different sizes separately. This environment...

This paper studies informal default in consumer credit as the start of a process of negotiation with the lender. We consider an economy with uninsurable individual risk where households in debt have also the option of declaring formal bankruptcy. In a calibrated version of the model, informal...

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...

This paper develops a new theory of long term unsecured credit contracts based on costly contracting that matches the data in a variety of dimensions. Credit lines are long term relations between lending firms and households that pre-specify a credit limit and interest rate in each period....
