This paper traces the evolution of John Maynard Keynes's theory of the business cycle from his early writings in 1913 to his policy prescriptions for the control of fluctuations in the early 1940s. The paper identifies six different "theories" of business fluctuations. With different theoretical...

Monetary and fiscal policy do not determine the stochastic path of prices: in the absence of financial policy, there remains indeterminacy indexed by an arbitrary probability measure over the set of states of the world. With an interest rate policy, and only if the asset market is complete,...

We use a new panel dataset of credit card accounts to analyze how consumers responded to the 2001 federal income tax rebates. We estimate the monthly response of credit card payments, spending, and debt, exploiting the unique, randomized timing of the rebate disbursement. We find that on average...

The consumption of households with liquid financial assets responds much more to transitory income shocks than the permanent-income hypothesis predicts. That is, middle class households with assets act as if they face liquidity constraints. This paper addresses this puzzling observation with a...

This paper studies the design of optimal fiscal policy when a government that fully trusts the probability model of government expenditures faces a fearful public that forms pessimistic expectations. We identify two forces that shape our results. On the one hand, the government has an incentive...

Does fiscal policy have qualitatively different effects on the economy in a liquidity trap? We analyze a nonlinear stochastic New Keynesian model and compare the true and loglinearized equilibria. Using the loglinearized equilibrium conditions, the answer to the above question is yes. However,...

We examine the impact of different degrees of fiscal feedback on debt in an economy with nominal rigidities where monetary policy is optimal. We look at the extent to which different degrees of fiscal feedback enhance or detract from the ability of the monetary authorities to stabilize output...

Japan is in the midst of a demographic transition that is both rapid and large by international standards. As recently as 1990, Japan had the youngest population among the Group of 6 large, developed countries. However, the combined effects of aging of the baby boomer generation and low...
