This paper investigates the empirical relevance of the Lucas critique. A database is constructed of all articles in the Social Science Citation Index that cite Lucas (1976). Those articles are characterized by the nature of the article, the context in which Lucas (1976) is cited, and the...

This paper demonstrates two advantages of well-known block variants of standard algorithms for solving nonlinear systems. First, if a problem is suf­ficiently close to block-diagonal, block algorithms may offer significant speed advantages on a single processor. Second, block Jacobi algorithms...

FRB/Global is a large-scale macroeconomic model developed and maintained by the Board's staff. This article provides a historical perspective on the development of the model, gives an overview of its structure, and highlights its dynamic properties with three simulation experiments: a reduction...

This paper examines variations on a baseline Fair-Taylor algorithm used to solve multi-country, rational expectations models. One notable feature of these variations is the ability to exploit small-scale distributed processing using a network of workstations or PCs. Using four processors to...

This paper describes the structure and illustrates the key features of FRB/Global, a large-scale macroeconomic model used in analyzing exogenous shocks and alternative policy responses in foreign economies and in examining the impact of these external shocks on the U.S. economy. FRB/Global...

The FRB Multicountry Model (MCM) is a linked system of five quarterly national macroeconometric models of the United States, Canada, Germany, Japan, and the United Kingdom. The MCM emphasizes international linkages, and has equations for trade in goods and services, investment income flows, and...

This overview describes the concepts of cointegration and exogeneity, focusing on analytical structure, statistical inference, and implications for policy analysis. Examples help clarify the concepts. The remainder of the overview summarizes the articles in a special issue of the Journal of...

A "structural" error correction model (in Boswijk's sense) is a rep­resentation of a conditional error correction model that satisfies certain restrictions. This paper examines the conditions under which such a struc­tural error correction model exists and when the associated representation is...

This paper provides an introduction to forecast uncertainty in empirical economic modeling. Forecast uncertainty is defined, various measures of forecast uncertainty are examined, and some sources and consequences of forecast uncertainty are analyzed. Empirical illustrations with the U.S. trade...

Both future disturbances and estimated coefficients contribute to the uncertainty in model-based ex ante forecasts, but only the first source is usually taken into account when calculating confidence intervals for practical applications. Schmidt (1974) and Baillie (1979) provide an easily...
