HOME OWNERSHIP AND THE WEALTH POSITION OF BLACK AND WHITE AMERICANS*

This paper examines the wealth position of blacks relative to whites, on the basis of data in the Survey of Economic Opportunity. The analysis indicates that at the same levels of both income and wealth blacks consistently invest more in consumer durables, especially housing, than do whites. The paper then explores possible explanations for this finding, suggesting that these investment differences are not solely due to the income and wealth position of blacks, but may be due to a smaller set of investment opportunities institutionally fostered by discriminatory forces.     

Using simulated mergers to evaluate corporate diversification strategies

This study suggests that simulated mergers can be used to help evaluate the effects of diversification on corporate performance. The results, which are consistent with a risk-reduction motive for conglomerate diversification, imply that conglomerate strategies focused on fewer and larger units may be advantageous in terms of certain measures of risk and return. Forecast error is used here to measure strategic risk, and return on equity is used to measure return.     

The structure and management of dual purpose funds

Dual fund shares allow individuals to satisfy their divergent preferences for the ordinary income and the capital gains components of return. Institutional restrictions on short selling are shown to permit discounts on dual funds to fluctuate within wide bounds. However, these fluctuations are shown to be consistent with informational efficiency. The average discount is shown to have a contemporaneous association with net redemptions of diversified open-end funds. It is shown that the high turnover of dual fund portfolios is not warranted by their portfolio performance and causes redistributions of wealth between income and capital shareholders.     

An econometric application of the theory of the farm-household

Employing a Cobb-Douglas specification for the production function and a modified linear expenditure system, the paper presents an econometric model of household production, consumption and labor supply behaviour for a semi-commercial farm with a competitive labor market. The model, estimated from primary, cross-sectional, Malaysian data, is used to analyse the impact of migration, output price intervention and technological change on the agricultural sector. In doing so, the wage-rate is treated as an endogenous variable to be determined by the interaction of aggregate labor demand and supply curves obtained from the estimated micro functions.

Price and margin rigidity in deflation: The great depression

The major hypothesis tested in this paper states that rigid price-cost margins in concentrated industries are an important cause of price rigidity. According to this view, while prices in all industries change with unit variable costs, prices in concentrated industries, where unit margins are rigid, change less than those in unconcentrated industries, where unit margins are more flexible. Three earlier and conflicting studies of price behavior in The Great Depression (1929–33) are reexamined. When these studies are subject to the same or similar tests, it is found that price rigidity is identified with concentration in the period considered.     

The concept of strategic groups: Theoretical construct or analytical convenience

Despite the fact that a great deal of empirical research confirms the existence of strategic groups, not enough attention has been paid to their theoretical development. This paper links the theories of spatial competition and cognitive taxonomy to the very existence of strategic groups in a competitive environment. It is shown that the concept of strategic groups is not an analytical convenience but a theoretical construct.     

Out of sight but not out of mind: Why failure to account for left truncation biases research on failure rates

We note at least three major issues in entrepreneurship theory that can be clarified by studying the survival chances of new ventures: the extent to which entrepreneurs are so constrained by initial founding conditions that they are unable to learn; the degree to which heterogeneity and innovative capabilities are lost due to the failure of new ventures; and the imprinting effects of new ventures' early days on their subsequent development. However, previous research on these issues has been inconclusive because of problems in research design and data analysis. In this paper, we shed light on new venture failure rates by assessing the validity and generalizability of previous findings. We argue that research using registration data to study new ventures is very likely to generate biased results and that research attempting to track new ventures from a very early stage can still suffer from selection bias due to left truncation. Using a sample of new ventures from the Panel Study of Entrepreneurial Dynamics II, we provide evidence for the extent of such biases. We offer a statistical solution to left truncation that can be easily applied in widely used statistical programs.
