The D4 RIN is the tradable compliance certificate for the biomass-based diesel mandate in the Renewable Fuel Standard (RFS). Understanding the price dynamics of the D4 RIN is important for understanding the RFS because its price sets a ceiling on the ethanol RIN (D6) and because some observers...

A firm may acquire additional caoital input by purchasing new capital or by increasing the utilization of its current capital. The margin between capital accumulation and capital utilization is studied in a model of dynamic factor demand where the firm chooses capital, labor, and their rates of...

China eventually becomes the world's saver and, thereby, the developed world's savoir with respect to its long-run supply of capital and long-run general equilibrium prospects. And, rather than seeing the real wage per unit of human capital fall, the West and Japan see it rise by one fifth by...

The New-Keynesian aggregate supply derives from micro-foundations an inflation-dynamics model very much like the tradition in the monetary literature. Inflation is primarily affected by: (i) economic slack; (ii) expectations; (iii) supply shocks; and (iv) inflation persistence. This paper...

Much recent monetary policy analysis has featured stochastic simulations with small structural macroeconomic models that include: a spending vs. saving ( IS') sector; a price-adjustment sector; and an interest rate policy rule. The first two are frequently specified so as to reflect optimizing...

In this paper, we derive and estimate relationships governing variable utilization of capital and labor for a firm solving a dynamic cost-minimization problem. Our method allows for (i) imperfect competition, (ii) increasing returns to scale, (iii) unobserved changes in utilization, (iv)...

It has long been argued that cyclical fluctuations in labor and capital utilization and the presence of overhead labor and capital are important for explaining procyclical productivity. Here I present two simple and direct tests of these hypotheses, and a way of measuring the relative importance...

This paper studies the relationship between real wages and unernployment in Europe. It finds no evidence that high real wages are responsible for the differing behavior of unemployment in Europe as contrasted with the U. S., and across European countries finds patterns of real wage behavior that...

I investigate the effects of an increase in the nominal interest rate on inflation and output in the United States and Japan during the postwar period. I postulate a structural autoregressive model that allows for transitory and permanent nominal and real shocks. I find that nominal...

We study the employment and output effects of the short-time work (STW) policy in Germany between 2009 and 2010. This intervention facilitated reductions in hours worked per employee with the goal of preventing layoffs. Using confidential German micro-level data we estimate a search model with...
