Needed: a theory of total factor productivity

This paper evaluates the argument that differences in physical and intangible capital can account for the large international income differences that characterize the world economy today. The finding is that they cannot. Savings rate differences are of minor importance. What is all-important is total factor productivity. In addition, the paper presents industry evidence that total factor productivities differ across countries and time for reasons other than differences in the publicly available stock of technical knowledge. These findings lead me to conclude a theory of TFP is needed. This theory must account for differences in TFP that arise for reasons other than growth in the stock of technical knowledge.Income distribution ; Productivity

Some observations on the Great Depression

The Great Depression in the United States was largely the result of changes in economic institutions that lowered the normal or steady-state market hours per person over 16. The difference in steady-state hours in 1929 and 1939 is over 20 percent. This is a large number, but differences of this size currently exist across the rich industrial countries. The somewhat depressed Japanese economy of the 1990s could very well be the result of workweek length constraints that were adopted in the early 1990s. These constraints lowered steady-state market hours. The failure of the Japanese people to display concern with the performance of their economy suggests that this reduction is what the Japanese people wanted. This is in sharp contrast with the United States in the 1930s when the American people wanted to work more.Depressions

Why do Americans work so much more than Europeans?

Americans now work 50 percent more than do the Germans, French, and Italians. This was not the case in the early 1970s when the Western Europeans worked more than Americans. In this paper, I examine the role of taxes in accounting for the differences in labor supply across time and across countries, in particular, the effective marginal tax rate on labor income. The population of countries considered is that of the G-7 countries, which are major advanced industrial countries. The surprising finding is that this marginal tax rate accounts for the predominance of the differences at points in time and the large change in relative labor supply over time with the exception of the Italian labor supply in the early 1970s.Hours of labor ; Taxation ; Labor supply
