In 1991, the U.S. Council of Economic Advisers undertook an initiative to increase the quality of economic statistics. One specific objective was to reduce the size of revisions in GNP estimates. The authors present evidence that one straightforward and inexpensive way of forwarding this objective is for the Department of Commerce to utilize better publicly available information released by other governmental agencies. An important caveat, however, applies: the relationship appears to be nonlinear. Specifically, the inefficient use of information is concentrated in those quarters where the change in the preliminary GNP estimate is large in absolute value.

The authors use the comparative behavior of real output growth and inflation behavior of members and nonmembers of the exchange rate mechanism (ERM) to analyze the importance of ERM membership on macroeconomic performance. An econometric procedure for identifying temporary and permanent shocks to output is proposed and executed. The results confirm that the ERM has acted as a vehicle for macropolicy coordination between members. The authors also investigate several issues relating to the hypothesis of global economic 'tri-polarity' between the United States, Germany, and Japan.

This paper proposes a methodology for obtaining estimates of firm-specific technical change econometrically and contrasts those estimates with a multilateral total factor productivity index. Based on a panel data set of airlines, two measures are contrasted in a variety of ways. To the extent that output characteristics differ as in the case of airlines, the two measures differ significantly. Both measures are regressed on a variety of factors potentially influencing technical efficiency, confirming that improvements in fuel efficiency and load factor have played major roles, with hubbing and competition playing smaller roles, in explaining efficiency improvements.
