This paper considers two central problems in our statistical frameworks which impair the ability to use wealth to assess economic sustainability or the impacts of economic downturns. Some increases in wealth may reflect increased economic rents--in particular, land and exploitation rents--and...

We examine the detailed structure of family income inequality in the United States, Canada, and Australia at various points during the 1980s. In each of these countries we find that income inequality increased among married couple families and that the increases are closely associated with...

This paper attempts to measure and explain recent changes in the distributions of family income in Canada and the U.S. using comparable micro-data for the two countries for 1979 and 1987. Three main sets of conclusions are reached. First, the distributions of total family income (pre-tax,...

This paper explores the relationship between technological change and inequality in the U.S. since the late 1960's. The analysis focuses primarily on studying patterns and trends in the dispersion of various distributions of earnings and income during this recent period of rapid technological...

Inequality is one of the main challenges posed by the proliferation of artificial intelligence (AI) and other forms of worker-replacing technological progress. This paper provides a taxonomy of the associated economic issues: First, we discuss the general conditions under which new technologies...

Technological diffusion implies a form of 'conditional convergence' as lagging countries catch up with technological leaders. We find strong evidence of technological diffusion but not full convergence; differences in total factor productivity (TFP) persist even in the long run due to differences...

A significant amount of the increase in the wealth income ratio in recent decades is due to an increase in the value of land. We present a series of models that explain why land prices may have increased. These models help us understand the increase in both the wealth income ratio and wealth...

A second extension analyzes the effects of land. We ask whether land holding displaces the holding of capital, resulting in workers being worse off. A tax on land, while reducing the value of land, leaves unchanged the capital-labor ratio, output per capita, and wages. But the tax reduces the...

Among the key results are: (i) The magnitude of wealth inequality does not, in general depend on the difference between the rate of interest (r) and the rate of growth (g); the former is itself an endogenous variable that needs to be explained. In the standard generalization of the Solow model,...

Explaining why the concepts of "capital" and "wealth" are distinct, we show that appropriately defined aggregates for wealth may be (and in the case of some countries appear to be) moving in opposite directions
