The stock market and investment

Changes in stock prices have substantial explanatory power forU.S. investment, especially for long-term samples, and evenin the presence of cash flow variables. The stock market dramaticallyout-performs a standard q-variable because the market-equitycomponent of this variable is only a rough proxy for stock marketvalue. Although the stock market did not predict accuratelyafter the crash of October 1987, the errors were not statisticallysignificant. Parallel relationship for Canada raise the puzzlethat Canadian investment appears to react more to the U.S. stockmarket than to the Canadian market.     

International data on educational attainment: updates and implications

This paper presents a data set that improves the measurementof educational attainment for a broad group of countries. Weextend our previous estimates to 1995 for educational attainmentfor the population over ages 15 and 25. We also provide projectionsfor 2000. We discuss the estimation method for the measuresof educational attainment and relate our estimates to alternativeinternational measures of human capital stocks.     

Social security and consumer spending in an international cross section

This paper expands the base of empirical evidence on the social security aggregate private saving issue by examining the behavior of consumer expenditure in 16 industrialized countries over the 1951–60 period. The results are mixed in that time series movements of social security exhibit a positive relation to consumer spending, while the cross-sectional variations reveal a negative association. Our overall conclusion is that the cross-country evidence provides neither empirical support for the hypothesis that social security depresses private saving nor an empirical refutation of that hypothesis. We argue that this indeterminacy of results applies also to previous studies of U.S. time series and to analyses of household cross sections in the U.S.     

Recent developments in monetary theory

This paper surveys recent work in monetary theory, with primary emphasis on material that has appeared since the writing of Harry Johnson's 1962 survey. The discussion deals with the following topics: (1) the theory of money demand, with special attention to inventory approaches; (2) money, inflation and growth; (3) the welfare cost of inflation, the optimum quantity of money, and inflationary finance; (4) disequilibrium theory; (5) the general equilibrium approach to monetary theory; (6) the new microfoundations of money; and (7) rational expectations and the Phillips Curve.     

Output and employment in a macro model with discrete transaction costs

The paper develops a macro model for determining output and employment when discrete transaction costs exist for paying wages and for purchasing commodities. Household labor supply is a function of an effective real wage, which modifies the apparent real wage to take account of the length of the payment period and the costs associated with buying and holding commodities. Firm labor demand is derived in a model where there are lumpy payroll costs associated with making wage payments. The behavior of households and firms is brought together in a market-clearing framework to determine the values of the real wage, employment and output, as well as the time intervals between wage payments and purchases of commodities. The effects of changes in the transaction and holding cost parameters are then examined by comparative-static techniques. An increase in any of these cost parameters turns out to reduce output and the amount of labor employed in production, but also tends to raise the amount of labor absorbed by the process of transacting. The tendency of transaction labor to move in the opposite direction from production labor implies that the net effects on total work are ambiguous.
