In macroeconomics, life-cycle models are typically used to address exclusively life-cycle issues. This paper shows that modeling the life-cycle may be important when addressing public policy issues, in this case the welfare costs of inflation. In the representative agent model, the optimal...

A widely cited failing of real business cycle models is their inability to account for the cyclical patterns of financial variables. Perhaps less well known is the fact that the return to capital and equity are identical in the neoclassical growth model. This paper constructs a measure of the...

Tax-based deficit reduction experiments for the U.S.\@ and EMU-12 are conducted using an open economy model. In welfare terms, raising the consumption tax is the least costly, followed by the labor income tax, then the capital income tax. Use of an open economy model means that the incidence of...

Capturing the boom phase of Pigou cycles and resolving the comovement problem requires positive sectoral comovement. This paper addresses these observations using a two sector New Keynesian model. Price rigidities dampen movements in the relative price of durables following a monetary policy...

In a neoclassical growth model with life-cycle households in which money is held to satisfy a cash-in-advance constraint, the optimal steady state inflation rate is not the Friedman rule -- it is in excess of $20\%$. Lump-sum, age-independent money injections twist and flatten the lifetime...

Shimer's puzzle is that the textbook Diamond-Mortensen-Pissarides model exhibits fluctuations in labor market variables that are an order of magnitude too small. Introducing search effort of the unemployed brings the model's predictions for these fluctuations very close to those seen in the...

It is well known that the Diamond-Mortensen-Pissarides model exhibits a strong trade-off between cyclical unemployment fluctuations and the size of rents to employment. Introducing endogenous job search effort reduces the strength of the trade-off while bringing the model closer to the data....

Based on a two sector dynamic new Keynesian model with sticky prices, this paper makes two contributions to the Pigou cycle literature. First, the paper quantifies the contribution of `news shocks' -- signals of future productivity changes. Maximum likelihood estimates indicate that nondurable...

Several approaches to finding the second-order approximation to a dynamic model have been proposed recently. This paper differs from the existing literature in that it makes use of the Magnus and Neudecker (1999) definition of the Hessian matrix. The key result is a linear system of equations...
