Since Christopher Sims's quot;Macroeconomics and Realityquot; (1980), macroeconomists have used structural VARs, or vector autoregressions, for policy analysis. Constructing the impulse response functions and variance decompositions that are central to this literature requires factoring the...

Longstanding speculation about the likelihood of a housing market collapse has given way in the past few months to consideration of just how far the housing market will fall and how much damage the debacle will inflict on the economy. In this paper, we discuss recent developments related to the...

The Gibson paradox, long observed by economists and named by John Maynard Keynes (1936), is a positive relationship between the interest rate and the price level. This paper explains the relationship by means of interest-rate, cost-push inflation. In the model: spending is driven in part by...

In his presidential address to the American Economic Association, Robert Lucas claimed that the welfare costs of the business cycle in the United States equaled .05 percent of consumption. His calculation compared the utility of a representative consumer receiving actual per-capita consumption...

The process of constructing impulse-response functions (IRFs) and forecast-error variance decompositions (FEVDs) for a structural vector autoregression (SVAR) usually involves a factorization of an estimate of the error-term variance-covariance matrix V. Examining residuals from a monetary VAR,...
