We argue that there are interesting examples of privately provided public goods that do not satisfy the assumption of strict normality, and reconsider voluntary-contribution games in a more general framework. We show that, in general, (1) equalizing transfers between individuals with identical tastes can increase total supply of the public good, and (2) more of the public good can be supplied if agents move sequentially rather than simultaneously. These results are in sharp contrast to earlier conclusions derived in the literature under the assumption of strict normality.  相似文献

This paper deals with local public expenditures, and the analysis is based on cross-section data for the Swedish municipalities. Two models are estimated; one is the basic median voter model where the decisive voter is assumed to be the voter with median income, while the other is a more general statistical alternative. The statistical alternative nests the basic median voter model as a special case, which makes it easy to test the null hypothesis that the basic median voter model is the correct model, given that the alternative is the true general structure. Although our results indicate a rejection of the null hypothesis, the estimation results are, nevertheless, similar for the two models.  相似文献

ABSTRACT

Using exchange-traded fund (ETF) options data, we examine the predictive power of variance risk premium on returns of four commodities: crude oil, natural gas, gold and silver. We also analyze the predictive power of upside and downside variance risk premiums using a decomposition model conditional on the direction of the underlying market movement. We find that both the undecomposed and decomposed variance risk premiums are able to predict commodity prices. The decomposed variance risk premiums, however, outperform the undecomposed premium. The importance of upside and downside variance risk premiums differs across markets, related to hedging demand. In energy markets, both upside and downside premiums have strong predictive power, while in precious metal markets, only the upside premium is predictive.  相似文献

We examine the phenomenon of the expanded use of non-tenure-track positions (“adjuncts”) and construct a supply-side Harris–Todaro model. Low adjunct wages are attributable to a “Hope Rent” from the gap between private opportunities and tenure-track utility.  相似文献

The ecological footprint is a measure of the resources necessary to produce the goods that an individual or population consumes. It is also used as a measure of sustainability, though evidence suggests that it falls short. The assumptions behind footprint calculations have been extensively criticized; I present here further evidence that it fails to satisfy simple economic principles because the basic assumptions are contradicted by both theory and historical data. Specifically, I argue that the footprint arbitrarily assumes both zero greenhouse gas emissions, which may not be ex ante optimal, and national boundaries, which makes extrapolating from the average ecological footprint problematic. The footprint also cannot take into account intensive production, and so comparisons to biocapacity are erroneous. Using only the assumptions of the footprint then, one could argue that the Earth can sustain greatly increased production, though there are important limitations that the footprint cannot address, such as land degradation. Finally, the lack of correlation between land degradation and the ecological footprint obscures the effects of a larger sustainability problem. Better measures of sustainability would address these issues directly.  相似文献

This study attempts to develop and empirically estimate an average cost and output reltion for average total for higher education. Statistical results based on data for top PhD granting institutions suggest there are economies of scale in higher education. Academic reputation is also an important variable in explaining variations in average total cost.  相似文献

Economic transition, higher education and worker productivity in China   总被引:1,自引:0,他引:1  
We investigate the role of education on worker productivity and firms' total factor productivity using a panel of firm-level data from China. We estimate the returns to education by calculating the marginal productivity of workers of different education levels based on estimates of the firm-level production function. We also estimate how the education level of workers and CEO contributes to firms' total factor productivity. Estimated marginal products are much higher than wages, and the gap is larger for highly educated workers. Our estimate shows that an additional year of schooling raises marginal product by 30.1%, and that CEO's education increases TFP for foreign-invested firms. Estimates vary substantially across ownership classes, the effect of schooling on productivity being highest in foreign-invested firms. We infer that market mechanisms contribute to a more efficient use of human capital within firms.  相似文献

The purpose of the study is to discuss some issues raised by K.J. Arrow in a recent study in this journal, ‘Higher education as a filter’. It is shown that the higher education system specified by Arrow utilizes known information to sort students according to their abilities. An alternative higher education system is developed which creates new information about the abilities of students by testing them. These two approaches are then compared and evaluated.  相似文献
