Abstract This paper derives a closed form solution for the Ramsey model with CRRA utility and Cobb-Douglas technology, for the case where capital's share is equal to the reciprocal of the intertemporal elasticity of substitution. The solution sheds light on the dynamics of the model and provides...

Abstract Since the seminal work of Blanchard and Katz, it has been widely believed that interstate migration causes state-level employment rates in the United States to revert rapidly to normal following a regional employment shock. This paper identifies two sources of bias in conventional...

Abstract This paper considers whether the sticky information model of Mankiw and Reis (2002) can robustly deliver inflation inertia. I find that four features of the model play a key role in determining inflation inertia: the frequency of information updating, the degree of real rigidities, the...

Abstract We study an optimal growth model with one-hoss-shay vintage capital, where labor resources can be allocated freely either to production, technology adoption or capital maintenance. Technological progress is partly embodied. Adoption labor increases the level of embodied technical...

Abstract Search-theory has become the main paradigm for the micro-foundation of money. But no comprehensive business cycle analysis has been undertaken yet with a search-based monetary model. This paper extends the model with divisible goods and divisible money of Shi (JET, 1998) to allow for...

Abstract Is the Great Depression amenable to real business cycle theory? In the 1970s and 1980s Lucas and Prescott took an abstentionist stance. They maintained that, because of its exceptional character, an explanation of the Great Depression was beyond the grasp of the equilibrium approach to...

Abstract We study standard monetary-policy rules with inflation-rate targets and either interest-rate or money-supply instruments using a flexible-price, perfect-foresight model. We focus mainly on interest-rate rules, but the results for money-supply rules are analogous. A locally-unique target...

Abstract Inflation can “grease” the wheels of the labor market by relaxing downward wage rigidity but it can also increase uncertainty and have a negative “sand” effect. This paper studies the grease effect of inflation by looking at whether the interaction between inflation and labor...

Abstract In recent decades there has been a worldwide shift toward market-oriented economic policies, sometimes termed 'neoliberalism’. In the policy arena this trend has been most apparent in the widespread move toward privatization and deregulation. And in the academic world there has been...

Abstract Inflation-targeting central banks have only imperfect knowledge about the effect of policy decisions on inflation. An important source of uncertainty is the relationship between inflation and unemployment. This paper studies the optimal monetary policy in the presence of uncertainty...
