We use new international price measures we have developed for machinery and transport equipment to explain changes in exports and export shares of the United States, Germany, and Japan. The effects of relative price changes on export shares are fairly large, producing relative quantity changes that are 50 to 100 per cent and as much as 200 per cent greater than the price changes. The effects of price changes seem to stretch out over 3 to 5 years and possibly longer. We also find that delays between order and delivery may affect measures of export quantity and of its response to price. Equations for individual countries suggest that exports by the United States are most responsive to relative price changes and those of Germany least responsive. The income elasticities are very sensitive to ...

In this paper, we will investigate the effect of six factors on occupational earnings inequality across all occupations in our sample and across occupations in five major Census subgroups. Those six factors are: differences in tasks, different levels of efficiency, institutional factors, time worked, the demand for labor and discrimination. Age and schooling will receive primary attention in our work and it will be shown that they are important determinants of earnings inequality among professional and clerical occupations but not among skilled, semi-skilled or unskilled occupations. Ability is also hypothesized as an important factor, but no measure of ability is provided in our sample. Differences in time worked and labor demand conditions, as measured by industrial and urban-rural mix,...
