IST shocks are often interpreted as multi-factor productivity (MFP) shocks in a separate investment-producing sector. However, this interpretation is strictly valid only when some stringent conditions are satisfied. Some of these conditions are at odds with the data. Using a two-sector model whose calibration is based on the U.S. Input-Output Tables, the authors consider the implications of relaxing several of these conditions. They show how the effects of IST shocks in a one-sector model differ from those of MFP shocks to an investment-producing sector of a two-sector model. MFP shocks induce a positive short-run correlation between consumption and investment consistent with U.S. data, while IST shocks do not. Illus. This is a print on demand report.

Our answer: Not so well. We reached that conclusion after reviewing recent research on the role of technology as a source of economic fluctuations. The bulk of the evidence suggests a limited role for aggregate technology shocks, pointing instead to demand factors as the main force behind the strong positive comovement between output and labor input measures.

Understanding the joint dynamics of internat. prices and quantities remains a central issue in internat. bus. cycles. Internat. relative prices appreciate when domestic consumption and output increase more than their foreign counterparts. In addition, both trade flows and trade prices display sizable volatility. This paper incorporates Hicks-neutral and investment-specific TS into a standard two-country general equilibrium model with variable capacity utilization and weak wealth effects on labor supply. Investment-specific TS introduce a source of fluctuations in absorption similar to taste shocks, thus reconciling theory and data. Also presents implications for the transmission mechanism of TS across countries. Illus. This is a print on demand pub.

American business has recently been under fire, charged with inflated pricing and an inability to compete in the international marketplace. However, the evidence presented in this volume shows that the business community has been unfairly maligned—official measures of inflation and the standard of living have failed to account for progress in the quality of business equipment and consumer goods. Businesses have actually achieved higher productivity at lower prices, and new goods are lighter, faster, more energy efficient, and more reliable than their predecessors. Robert J. Gordon has written the first full-scale work to treat the extent of quality changes over the entire range of durable goods, from autos to aircraft, computers to compressors, from televisions to tractors. He combines and extends existing methods of measurement, drawing data from industry sources, Consumer Reports, and the venerable Sears catalog. Beyond his important finding that the American economy is more sound than officially recognized, Gordon provides a wealth of anecdotes tracing the postwar history of technological progress. Bolstering his argument that improved quality must be accurately measured, Gordon notes, for example, that today's mid-range personal computers outperform the multimillion-dollar mainframes of the 1970s. This remarkable book will be essential reading for economists and those in the business community.

The classic introduction to the New Keynesian economic model This revised second edition of Monetary Policy, Inflation, and the Business Cycle provides a rigorous graduate-level introduction to the New Keynesian framework and its applications to monetary policy. The New Keynesian framework is the workhorse for the analysis of monetary policy and its implications for inflation, economic fluctuations, and welfare. A backbone of the new generation of medium-scale models under development at major central banks and international policy institutions, the framework provides the theoretical underpinnings for the price stability–oriented strategies adopted by most central banks in the industrialized world. Using a canonical version of the New Keynesian model as a reference, Jordi Galí explores various issues pertaining to monetary policy's design, including optimal monetary policy and the desirability of simple policy rules. He analyzes several extensions of the baseline model, allowing for cost-push shocks, nominal wage rigidities, and open economy factors. In each case, the effects on monetary policy are addressed, with emphasis on the desirability of inflation-targeting policies. New material includes the zero lower bound on nominal interest rates and an analysis of unemployment’s significance for monetary policy.
