Conventional models predict that workers consider employment opportunities and monetary rewards expected over their lifetimes when making current period decisions such as whether to quit a job. This article tests the hypothesis that later career opportunities affect quit decisions by examining the relationship between teaching and school administration. Evidence on the extent to which administrative positions are available to teachers, and the salary premia associated with them, is presented. Discrete time logit-hazard models of teacher quits, estimated using data from New York State, provide some support for the hypothesis, though the magnitudes of the estimated effects are small.

The variances of pricing errors (transitory changes in prices) at the NYSE open and the close are analyzed for U.S. stocks that are traded in London or Tokyo, British and Japanese stocks that are listed on the NYSE, and U.S. stocks that are not traded abroad. The variance of pricing errors is significantly greater at the open than at the close for U.S. stocks, but not foreign stocks. These differences are explained by differences in order flow at the open and the close, a relation that is the same whether stocks are foreign or domestic and whether they trade abroad or notJournal of Economic LiteratureClassification Numbers: G10, D23.

This article explores a Census Bureau survey of the small business sector, the 1982 Characteristics of Business Owners survey, which contains information on both small businesses and the managers running them. A number of patterns are documented. For example, among small businesses of the same age, the probability that a business fails and the probability that a business is sold are both initially decreasing in the tenure of the manager at the business. Among businesses with managers who have the same tenure at their business, the probability that a business fails is decreasing in the age of the business.

We use data from the Canadian 2-year longitudinal Labour Market Activity Survey of 1986-87 to estimate the effect of the Unemployment Insurance (UI) system on job duration. Particular attention is focused on the "entrance requirements" of the UI system, which relate eligibility for UI benefits to an individual's recent employment history. The article makes operational the UI entrance requirement provisions which take into account variations in the regional unemployment rate. Controlling for many personal and job characteristics, we find evidence that a significant number of jobs terminate when they have reached the duration that would permit a UI claim.

Price improvement is the difference between the execution price of an order and the quoted bid or ask when the order was submitted. We show that expected price improvement falls off dramatically as the size of the order approaches the quoted depth, and becomes negative for larger orders. This is particularly important for small firms because the quoted depths are low. Using quoted spreads and depths and our estimate of expected price improvement, we show that trading strategies that attempt to exploit the weekly predictability of small-firm returns would be swamped by transaction costs.

The papers by Venkatachalam (1996) and Aboody (1996) provide some interesting evidence on issues that are important to accounting regulators as well as accounting academics. However, for econometric as well as economic reasons, there are limits to what we can learn from this type of research (cross-sectional ‘levels’ studies). Careful attention to methodological issues in this type of research design can reduce, but likely will not eliminate, these interpretational difficulties.
