This paper examines the determinants of the EPAs litigation strategy between 1977 and 1996 focusing on the tenure of Ann Gorsuch. Two hypotheses about this period are tested: (1) that changes in the EPAs litigation strategy were in fact an effort to reduce the expected penalty for violating environmental laws or (2) that the changes made in litigation strategy were consistent with efforts to reduce transaction cost. Contrary to previous research, I find no conclusive evidence of an overall shift toward business interests in EPA prosecutions. There is, however, clear evidence of shifts in the EPAs litigation strategy across administrations.  相似文献

Abstract

This paper examines the connections linking recent changes in Latino migration, the American meatpacking industry, and American immigration policy. As the meatpacking industry has vertically integrated and shifted to rural non-union areas throughout the South, it has grown increasingly dependent on short-term low-skilled employees. This process can be understood as the industrialization of meatpacking, where profitability depends on continuous high-throughput production. To succeed, the industrialization of meatpacking requires a large pool of easily replaceable labor that has no control over the pace work on of the shop floor. At the same time, as immigrants have been drawn to these new company towns, American immigration policy has turned increasingly towards border enforcement. We argue that the presence of illegal immigrants within the factories reduces the bargaining power of shop workers and increases employer control. Most studies of immigration have focused on the supply of migrant labor, the immigrants attracted to higher paying jobs. We argue that valuable insight is gained by looking at the manufacturers' demand for cheap labor and the implementation of an industrial strategy that requires it.  相似文献

Price-cap regulation is widely applied to network industries. However, regulators often encounter the problem of asymmetric information on efficient costs. Benchmarking can help reduce this problem. We present a benchmarking analysis, conducted for an Australian regulator, that derives measures of efficiency for Australian gas distributors relative to U.S. counterparts. Several techniques, such as data envelopment analysis and stochastic frontier analysis, are used to ensure that our measures are robust to methodology choice. We conclude with a discussion of how the regulator used the benchmarking results, along with other information, to help it determine appropriate price caps.  相似文献

Precautionary Demand for Education, Inequality, and Technological Progress   总被引:1,自引:1,他引:1  
This paper offers an explanation for the evolution of wage inequality within and between industries and education groups over the past several decades. The model is based on the disproportionate depreciation of technology-specific skills versus general skills due to technological progress, which occurs randomly across sectors. Consistent with empirical evidence, the model predicts that increasing randomness is the primary source of inequality growth within uneducated workers, whereas inequality growth within educated workers is determined more by changes in the composition and return to ability. Increasing randomness generates a precautionary demand for education, which we show empirically to be significant.  相似文献

Bipolar disorders (BD) are among the most significantly impairing of childhood and adolescent psychiatric disorders. Although BD symptoms may begin in adolescence, they are frequently not diagnosed until adulthood, and accordingly BD scales could aid diagnostic assessment in paediatric populations. This review aims to synthesis the evidence for the accuracy of BD symptom index tests for discriminating BD from non-BD (other diagnoses or healthy controls) in paediatric population. Additionally, several theoretically relevant moderators of diagnostic accuracy were evaluated.  相似文献

In this paper, we use a unified framework of competing exporters and competing importers models where political biases in both exporting and import-competing sectors influence governments' decisions in trade agreement formation and external tariff setting. Using an endogenous trade agreement formation model, we show that the relative strength of political biases in import-competing and exporting sectors are pivotal in determining the free-riding incentives, exclusion incentives and whether the ability to form free trade areas acts as building or stumbling blocks towards multilateral free trade. When the political biases toward exporting and import-competing sectors are sufficiently weak, the ability to form free trade agreements acts as strong building blocks toward free trade. However, when the political bias towards exporting sectors is at the intermediate range and political bias towards import-competing sectors is sufficiently strong, the ability to form free trade agreements acts as strong stumbling blocks.  相似文献

This article investigates the relation between risk and individual well-being. We propose a theoretical model of happiness that makes a distinction between ex ante evaluations of happiness and ex post assessments. The main assumptions of the model are tested through three studies based on anchoring vignettes. We show that, even if, ex ante, consumers fear high risk and do not associate it to a high level of happiness, their ex post evaluation of well-being is generally higher when identical consequences result from a high-risk situation than from a low-risk situation. Control over risk-taking reinforces the gap between ex ante and ex post measures of happiness. Thus, our article provides empirical evidence about a positive relation between risk and individual well-being, suggesting that risky experiences have the potential to increase consumer well-being.  相似文献

The aggregation of individual random AR(1) models generally leads to an AR(∞) process. We provide two consistent estimators of aggregate dynamics based on either a parametric regression or a minimum distance approach for use when only macro data are available. Notably, both estimators allow us to recover some moments of the cross-sectional distribution of the autoregressive parameter. Both estimators perform very well in our Monte-Carlo experiment, even with finite samples.  相似文献

This paper develops an air passenger model that deals with city-pair demand generation and demand assignment in a single framework. Using publicly available and regularly collected panel data, the model captures both time series and cross-sectional variation of air travel demand. The empirical analysis finds that pattern of correlations among alternatives can be described by a three-level nested logit model. Fare, frequency, flight time, direct routing, on-time performance, income, and market distance have significantly effects on air demand. Correcting for the problem of endogenous air fares using instrumental variables yields more plausible estimates of price sensitivity and value of time.  相似文献
