Renewed interest in fiscal policy has increased the use of quantitative models to evaluate policy. Because of modelling uncertainty, it is essential that policy evaluations be robust to alternative assumptions. We find that models currently being used in practice to evaluate fiscal policy...

Much of the recent economic debate about the impact of stimulus packages has focused on the size of the crucial government purchases multiplier. But equally crucial is the size of the government purchases multiplicand--the change in government purchases of goods and services that the multiplier...

Recently we were asked to serve on the President's Commission to Strengthen Social Security (CSSS) along with 14 other members drawn equally from both major political parties. The Commission's charge was to provide recommendations to modernize the Social Security system, restore its fiscal...

Subsidies for health insurance for chronically ill, high-cost individuals may increase coverage in the broader population by improving the functioning of insurance markets. In this paper, we assess an historical example of a policy intervention of this sort, the extension of Medicare to the...

This paper examines the causes of the decline in black male teenage employment from 1950 to 1970. During this period, the employment-to-population ratio of black youth (age 16-19) declined from 46.8 percent to 27 percent. The white teenage employment ratio, in contrast, remained constant. The...

In this paper, we calculate the consequences for health spending and federal revenues of an above-the-line deduction for out-of-pocket health spending. We show how the response of spending to this expansion in the tax preference can be specified as a function of a small number of behavioral...

In this paper, we estimate the effect of the tax preference for health insurance on health care spending using data from the Medical Expenditure Panel Surveys from 1996-2005. We use the fact that Social Security taxes are only levied on earnings below a statutory threshold to identify the impact...

Research in the early 1980s found that the gains from international coordination of monetary policy were quantitatively small compared to simply getting domestic policy right. That prediction turned out to be a pretty good description of monetary policy in the 1980s, 1990s, and until recently....

The purpose of this paper is to report on a comparison of several alternative numerical solution techniques for nonlinear rational expectations models. The comparison was made by asking individual researchers to apply their different solution techniques to a simple representative agent, optimal,...

At the center of the financial market crisis of 2007-2008 was a highly unusual jump in spreads between the overnight inter-bank lending rate and term London inter-bank offer rates (Libor). Because many private loans are linked to Libor rates, the sharp increase in these spreads raised the cost...
