What Determines Debt Maturity?
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 firms with better current earnings and better growth prospects issue debt with longer maturity, while firms operating in more-volatile environments issue debt with shorter maturity. Yield to maturity is a poor indicator of the risk of debt issued by a firm. The reason is simple: Yield to maturity captures ...

Optimal Monetarist Arithmetic or How to Inflate If You Must
In their celebrated 1981 paper ”Some Unpleasant Monetarist Arithmetic,” Sargent and Wallace show that when a central bank is required to transfer resources to the fiscal authority, it faces a trade-off: if it chooses to keep inflation low in the short run, then it must be willing to accept higher inflation in the long run. In this paper I characterize the optimal interest rate (and inflation) policy by a central bank faced with a version of the Sargent-Wallace scenario. I explore this question in a setting in which a certain amount has to be transferred for an uncertain period of time. I ...

Frictionless technology diffusion: the case of tractors
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 this to be incorrect. Once the appropriate driving forces are taken into account, the neoclassical model can account for 'slow' adoption. We illustrate this by developing an industry model to study the equilibrium rate of diffusion of tractors in the U.S. between 1910 and 1960.

Optimal Management of an Epidemic: Lockdown, Vaccine and Value of Life
This paper analyzes the optimal management of a pandemic (stay-at-home and vaccination policies) in a dynamic model. The optimal lockdown policies respond to the spread of the virus with significant restrictions to employment, followed by partial loosening before the peak of the epidemic. Upon the availability of a vaccine, the optimal vaccination policy has an almost bang-bang property, despite the loss of immunity of the vaccinated: vaccinate at the highest possible rate, and then rapidly converge to the steady state. The model illustrates interesting trade-offs as it implies that lower ...

Growth and business cycles
We present a class of convex endogenous growth models and analyze their performance in terms of both growth and business cycle criteria. The models we study have close analogs in the real business cycle literature. We interpret the exogenous growth rate of productivity as an endogenous growth rate of human capital. This perspective allows us to compare the strengths of the two classes of models. ; To highlight the mechanism that gives endogenous growth models the ability to improve upon their exogenous growth relatives, we study models that are symmetric in terms of human and physical capital ...

Why are married women working so much?
We study the large observed changes in labor supply by married women in the United States over 1950-1990, a period when labor supply by single women has hardly changed at all. We investigate the effects of changes in the gender wage gap, technological improvements in the production of nonmarket goods and potential inferiority of these goods on understanding this change. We find that small decreases in the gender wage gap can explain simultaneously the significant increases in the average hours worked by married women and the relative constancy in the hours worked by single women, and single ...

Frictionless technology diffusion: the case of tractors
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 this fact is inconsistent with the predictions of the frictionless neoclassical model. In this paper we study the specific case of the diffusion of the tractor in American agriculture between 1910 and 1960. There are three important driving forces: changes in quality, wage rates and prices of substitutes such as horses and mules. We demonstrate that once these exogenous forces are taken into account, the standard ...
