In this paper we use a standard neoclassical model supplemented by some frictions to understand large price swings in the housing market. We construct a two good general equilibrium model in which housing is a composite good produced using structures and land. We revisit the connection between...

We develop a model of retirement and human capital investment to study the effects of tax and retirement policies. Workers choose the supply of raw labor (career length) and also the human capital embodied in their labor. Our model explains a significant fraction of the US-Europe difference in...

Perhaps no question has attracted as much attention in the economics literature as “Why are some countries richer than others?� In this article, the author revisits the “development problem� and provides some estimates of the importance of human capital in accounting...

We study the endogenous determination of corporate debt maturity in a setting with default risk. We assume that firms must access the bond market and they issue debt with a flexible structure (coupon, face value, and maturity). Initially, the firm is in a low growth/illiquid state that requires...

What determines the maturity structure of debt? In this article, I develop a simple model to explore how the optimal maturity of debt issued by a firm (or a country) depends both on the firm’s cyclical state and other features of the economic environment in which it operates. I find that...

Many new technologies display long adoption lags, and this is often interpreted as evidence of frictions inconsistent with the standard neoclassical model. In this paper we study the diffusion of the tractor in American agriculture between 1910 and 1960 – a well known case of slow diffusion...

Empirical evidence suggests that there is a long lag between the time a new technology is introduced and the time at which it is widely adopted. The conventional wisdom is that these observations are inconsistent with the predictions of the frictionless neoclassical model. In this paper we show...
