While information technologies (IT) are credited with the recent acceleration in productivity in the United States, many other industrial countries have not experienced a pickup in productivity growth. To explain this productivity divergence, we use panel data from 1992 to 1999 for 13 industrial...

We study whether aggregation residuals in U.S. private investment in information technology (IT) exhibit a predictable pattern that is consistent with Hicks' composite-good theorem and that may be used for forecasting. To determine whether one can extract such a pattern, we apply the...

One of the most remarkable macroeconomic developments of the past decade has been the widespread decline in inflation despite declines in unemployment rates. For the United States, these seemingly contradictory developments have been reconciled in terms of three factors: (1) an acceleration in...

One cannot exaggerate the importance of estimating how international trade responds to changes in income and prices. But there is a tension between whether one should use models that fit the data but that contradict certain aspects of the underlying theory or models that fit the theory but...

This paper provides a comprehensive study of the interplay between the Federal Reserve's balance sheet and overnight interest rates. We model both the supply of and the demand for excess reserves, treating assets of the Federal Reserve as policy tools, and estimate the effects of conventional...

Summarizing Hendry's forty years of work on taming uncertainty is "clear and distinct": Test, test, test. Sure - but test what? Test the maintained assumptions of the disturbances. Test the parameter restrictions of a given model. Test the explanatory power of a model against a rival model. In...
