We study the interaction of multiple large economies in dynamic stochastic general equilibrium. Each economy has a monetary policymaker that attempts to control the economy through the use of a linear nominal interest rate feedback rule. We show how the determinacy of worldwide equilibrium...

Since the third quarter of 2000, the U.S. economy began to experience a slowdown in its rate of growth. This slowdown serves as a reminder that the business cycle is still alive and raises the following questions: What do we know about the driving forces behind the business cycle? What should...

This paper offers an explanation of the resilience of IS-LM models, which are still alive more than sixty years after the birth of the first prototype despite growing criticism within the profession. To this end two significant episodes of their evolution are examined in some detail: the genesis...

Macroeconomists have largely converged on method, model design, reduced-form shocks, and principles of policy advice. Our main disagreements today are about implementing the methodology. Some think New Keynesian models are ready to be used for quarter-to-quarter quantitative policy advice; we do...

This paper identifies a novel form of dynamic inconsistency of stabilization policy in increasing returns models that generate multiple equilibria. We present a two-period version of the Benhabib-Farmer (1994) externalities model and derive closed-form solutions for all endogenous variables in...

This paper compares different methods for estimating forward-looking output and inflation Euler equations and shows that weak identification can be an issue in conventional GMM estimation. The authors propose a GMM procedure that imposes the dynamic constraints implied by the forward-looking...

After a brief review of classical, Keynesian, New Classical and New Keynesian theories of macroeconomic policy, we assess whether New Keynesian Economics captures the quintessential features stressed by JM Keynes. Particular attention is paid to Keynesian features omitted in New Keynesian...

Underconsumption theories played an important part in the economic policy debates during the Great Depression of the 1930s. The commonsense appeal of the arguments and the clear cut policy advice secured their proponents' popular support. Here, the contributions of John A. Hobson, Emil Lederer,...

In the data, prices change both temporarily and permanently. Standard Calvo models focus on permanent price changes and take one of two shortcuts when confronted with the data: drop temporary changes from the data or leave them in and treat them as permanent. We provide a menu cost model that...
