We study the portfolio selection problem of an investor who can optimally exert costly effort for more income. The possibility of generating more income, if necessary, increases the risk-taking appetite of the investor. We find the optimal allocation to the risky security as a proportion of financial wealth and as a proportion of the total wealth, defined as the combination of the financial wea...

Campbell (1993) has employed a log-linearized approximation to an aggregate budget constraint to show how the ratio of consumption to total (human and non-human) wealth summarizes agents’ expectations concerning both future labor income and future asset returns. A problem with implementing this approach empirically is the unobservability of human wealth. Recently, Lettau and Ludvigson (2001a) h...

Wealth Distribution within Couples While most studies on wealth inequality focus on the inequality between households, this paper examines the distribution of wealth within couples. For this purpose, we make use of unique individual level micro data from the German Socio-Economic Panel Study (SOEP). In married and cohabiting couples men’s net worth, on average, is 33,000 euros higher than women...

This paper examines the permanent and transitory effects of changes in wealth, the top federal marginal income tax rate, and capital gains tax rate on the distribution of Adjusted Gross Income (AGI). This paper establishes the importance of wealth in determining the distribution of AGI, and results here suggest that its effects can negate the permanent effect of a change in both tax rates. Of t...

We use survey data to compare the income and consumption of baby boomers in 1989 with that of their parents' generation in the early 1960s when they were the same ages. Various adjustments allow for changes in household composition and living arrangements. We also assess how wealth accumulation by baby boomers compares to that of their parents' generation. We find that boomers on average have a...

This paper suggests multidimensional affluence measures for the top of the distribution. In contrast to commonly used top income shares, they allow the analysis of the extent, intensity and breadth of affluence in several dimensions within a common framework. We illustrate this by analyzing the role of income and wealth as dimensions of multidimensional well-being in Germany and the US in 2007 ...
