Previous tests for convexity in the Phillips curve have been biased because researchers have employed filtering techniques for the NAIRU that have been fundamentally inconsistent with the existence of convexity. This paper places linear and nonlinear models of the Phillips curve on an equal...

This paper develops a 2-country New Keynesian overlapping generations model suitable for the joint evaluation of monetary and fiscal policies. We show that a permanent increase in U.S. government deficits raises the world real interest rate and significantly increases U.S. current account...

The Phillips curve has generally been estimated in a linear framework. This paper investigates the possibility that the Phillips curve is indeed a curve, and shows that a convex short-run Phillips curve may be a more accurate representation of reality than the traditionally used linear...

This paper examines the macroeconomic implications of life-cycle and dynastic saving behavior for closed and small, open economies. Using an extended version of Blanchard’s overlapping agents model, the analytical framework nests these two competing views, treating agents as either dynastic...

This paper uses the IMF's Global Integrated Monetary and Fiscal Model to compute shortrun multipliers of fiscal stimulus measures and long-run crowding-out effects of higher debt. Multipliers of two-year stimulus range from 0.2 to 2.2 depending on the fiscal instrument, the extent of monetary...
