摘要：This paper compares the performance of U.K. plants that were acquired by the foreign-owned sector during 1987-1992 with other comparable subgroups of plants operating at the same time (including plants acquired by U.K.-owned companies). The principal aim is to consider the types of plants that were acquired and whether after acquisition they performed above or below average when compared to other manufacturing plants. The results show that foreign-owned enterprises acquired the most-productive...

摘要：This paper analyzes both theoretically and empirically how an absolute grading standard that allows only a small number of distinct grades affects student course performance outcomes. The clearest prediction of the model is that course performance of grade-motivated students will tend to be clustered slightly above the boundaries that separate grades, as long as the variance of the random component of performance is not too large. A more tenuous prediction is that the proximity of a grade-moti...

摘要：This study evaluates the roles of ideology, constituency, and political party for roll-call voting in the U.S. Senate on a broad set of environmental issues. The study estimates a model of political support using voting scores from the League of Conservation Voters (LCV) for the period 1988-1998, including observations on 91 senators for 130 roll-call votes. The study decomposes the scale-adjusted scores into relative weights due to the general electorate, the senator's support constituency, p...

摘要：This paper uses an updated and revised panel data set on ambient air pollution in cities worldwide to examine the robustness of the evidence for the existence of an inverted U-shaped relationship between national income and pollution. We test the sensitivity of the pollution-income relationship to functional forms, to additional. covariates, and to changes in the nations, cities, and years sampled. We find that the results are highly sensitive to these changes, and conclude that there is littl...

摘要：We use data from a sample of child care centers to estimate the relationships between cost and child care quality, and between revenue and quality. We use a measure of child care quality, designed by developmental psychologists, that is positively associated with child development. Taking the estimated cost-quality and revenue-quality relationships as given, we estimate the objective functions of firms and compute the quality supply function. The results indicate that the supply of quality is ...

摘要：The use of incentive regulation and other alternative regulatory programs in U.S. electricity markets has grown during the past two decades. Within a stochastic frontier framework, I investigate the effect of individual programs on the technical efficiency of a large set of coal and natural gas generation units. I find that those programs tied directly to generator performance and those that modify traditional fuel cost pass-through programs, to provide a greater incentive to reduce fuel costs...

摘要：For a genuine small open economy that has experienced both dictatorship and democracy, we find support for the predictions of the Grossman-Helpman (1994) Protection for Sale model. In contrast to previous studies, we use various protection measures (including tariffs, the direct measure of the theoretical model) and perform both single-year and panel regressions. Using Turkish industry-level data, the government's weight on welfare is estimated to be much larger than that on contributions. Mor...
