Knowledge that Transforms

This paper examines how personal bankruptcy and bankruptcy exemptions affect the supply and demand for credit. While generous state-level bankruptcy exemptions are probably viewed by most policy-makers as benefiting less-well-off borrowers, our results using data from the 1983 Survey of Consumer Finances suggest that they increase the amount of credit held by high-asset households and reduce the availability and amount of credit to low-asset households, conditioning on observable characteristics. Thus, bankruptcy exemptions redistribute credit toward borrowers with high assets. Interest rates on automobile loans for low-asset households also appear to be higher in high exemption states.

No. This paper investigates the relationship between financing constraints and investment-cash flow sensitivities by analyzing the firms identified by Fazzari, Hubbard, and Petersen as having unusually high investment-cash flow sensitivities. We find that firms that appear less financially constrained exhibit significantly greater sensitivities than firms that appear more financially constrained. We find this pattern for the entire sample period, subperiods, and individual years. These results (and simple theoretical arguments) suggest that higher sensitivities cannot be interpreted as evidence that firms are more financially constrained. These findings call into question the interpretation of most previous research that uses this methodology.

Explaining cross-country differences in growth rates requires not only an understanding of the link between growth and public policies, but also an understanding of why countries choose different public policies. This paper shows that ethnic diversity helps explain cross-country differences in public policies and other economic indicators. In the case of Sub-Saharan Africa, economic growth is associated with low schooling, political instability, underdeveloped financial systems, distorted foreign exchange markets, high government deficits, and insufficient infrastructure. Africa's high ethnic fragmentation explains a significant part of most of these characteristics.

This paper documents how plant-level wages, occupational mix, workforce education, and productivity vary with the adoption and use of new factory automation technologies such as programmable controllers, computer-automated design, and numerically controlled machines. Our cross-sectional results show that plants that use a large number of new technologies employ more educated workers, employ relatively more managers, professionals, and precision-craft workers, and pay higher wages. However, our longitudinal analysis shows little correlation between skill upgrading and the adoption of new technologies. It appears that plants that adopt new factory automation technologies have more skilled workforces both pre- and postadoption.

We propose that dispersed outside ownership and the resulting managerial discretion come with costs but also with benefits. Even when tight control by shareholders is ex post efficient, it constitutes ex ante an expropriation threat that reduces managerial initiative and noncontractible investments. In addition, we show that equity implements state contingent control, a feature usually associated with debt. Finally, we demonstrate that monitoring, and hence ownership concentration, may conflict with performance-based incentive schemes.

This paper argues that the typical household's saving is better described by a “buffer-stock” version than by the traditional version of the Life Cycle/Permanent Income Hypothesis (LC/PIH) model. Buffer-stock behavior emerges if consumers with important income uncertainty are sufficiently impatient. In the traditional model, consumption growth is determined solely by tastes. In contrast, buffer-stock consumers set average consumption growth equal to average labor income growth, regardless of tastes. The model can explain three empirical puzzles: the “consumption/income parallel” documented by Carroll and Summers; the “consumption/income divergence” first documented in the 1930s; and the stability of the household age/wealth profile over time despite the unpredictability of idiosyncratic wealth changes.

This paper reports measures of preference parameters relating to risk tolerance, time preference, and intertemporal substitution. These measures are based on survey responses to hypothetical situations constructed using an economic theorist's concept of the underlying parameters. The individual measures of preference parameters display heterogeneity. Estimated risk tolerance and the elasticity of intertemporal substitution are essentially uncorrelated across individuals. Measured risk tolerance is positively related to risky behaviors, including smoking, drinking, failing to have insurance, and holding stocks rather than Treasury bills. These relationships are both statistically and quantitatively significant, although measured risk tolerance explains only a small fraction of the variation of the studied behaviors.

A survey of 184 firms was conducted to investigate the reasons for wage rigidity. The strongest support was found for explanations based on adverse selection in quits and on the effect of wages on effort. In addition, survey respondents indicated that reducing turnover is an important explanation of wage rigidity for white-collar workers, and that implicit contracts are an important explanation for other workers. Respondents also believed that effort responds more strongly to wage decreases than to wage increases and that wage decreases have a greater impact on the effort of low-skilled workers than of high-skilled workers.

Two core meanings of “utility” are distinguished. “Decision utility” is the weight of an outcome in a decision. “Experienced utility” is hedonic quality, as in Bentham's usage. Experienced utility can be reported in real time (instant utility), or in retrospective evaluations of past episodes (remembered utility). Psychological research has documented systematic errors in retrospective evaluations, which can induce a preference for dominated options. We propose a formal normative theory of the total experienced utility of temporally extended outcomes. Measuring the experienced utility of outcomes permits tests of utility maximization and opens other Unes of empirical research.
