In this paper, I show that nineteenth century US interest rates are relatively more volatile before 1874 and I propose, and demonstrate how, commodity futures trading is the likely principal proximate explanation for this change in behavior. Borrowing from Turnovsky [Econometrica 51 (1983) 1363], I model the optimizing behaviors of risk averse producers and risk neutral speculators in the absence and presence of futures contracts and I show that, so long as one party to a futures contract was risk averse, futures markets would have quelled interest rate volatility caused by variations in planting and harvesting conditions.  相似文献

This paper presents a model of innovations and endogenous economic growth with two main assumptions: first, the cost of searching for innovations differs across innovations, and second, innovations take time to find. The paper shows that given these two assumptions together, competition leads to patent races and to duplication of innovative activity. The paper then shows that duplication significantly reduces the effect of scale on growth. It also shows that competitive R&D creates too much research on easy innovations, and too little research on the difficult ones. Finally, the paper shows that risk sharing might increase duplication and reduce growth.  相似文献

Investigating the impact of public subsidies on farm technical efficiency is becoming a critical issue in applied agricultural policy analysis. This article presents a meta-analysis of empirical results on this issue, based on data gathered from a systematic literature review. We find that, in the empirical literature, subsidies are commonly negatively associated with farm technical efficiency. Meta-regression estimation results show that the direction (significantly negative, significantly positive or non-significant) of the observed effects is sensitive to the way subsidies are modelled in the empirical studies.  相似文献

There is an ongoing debate over the impact of corporate pro-environment actions and strategies (reflected, for example, in pollution prevention and emission reductions, product re-design, materials stewardship) on corporate financial performance in US corporations today. A review of the existing literature in this area yields no consistent pattern of relationships between corporate environmental proactivism and financial performance when historical corporate accounting performance and stock market measures of performance are used. We revisit this relationship using a novel measure of firm performance: security analyst earnings forecasts. Specifically, we demonstrate a significant, negative relationship between environmental proactivism (using Toxic Release Inventory data) and industry analyst 1- and 5-year earnings-per-share performance forecasts for a sample of 523 US firms in 1992. We discuss the implications of these findings and provide suggestions for future research. © 1997 John Wiley & Sons, Ltd and ERP Environment.  相似文献

This paper is a study of the perceptions of young adults in the U.S. and China on the relations between the two nations. We conducted a case study by distributing a 17 question survey to 201 American undergraduate students (NYC) and 164 Chinese undergraduate students (Shanghai). The questions probed their views of U.S. and China’s economic and political systems, the future economic growth and political power in the world of the two nations, and the future political and economic relations between the two powers. The results of our study reveal a number of important perceptions that both U.S. and Chinese students have, some being similar and others being in sharp contrast. Most students in both countries view future political and economic relations between the U.S. and China predominantly as cooperative but only based on each nation’s self-interests. Both Chinese and American students agree that China is gaining political strength and economic influence among the advanced and the emerging nations of the world. While most of the U.S. students believe that China has been and will continue to grow at a much faster rate than the U.S., Chinese students are more likely to believe that this rate of growth is unsustainable. The results from our survey are compared and contrasted to the findings of national surveys for both countries. We believe that the study provides valuable insights into the similarities and differences in viewpoints of the next generation of adults in both nations about future U.S.-China relations.  相似文献

This paper investigates whether momentum trading strategies are profitable in the Hong Kong stock market, and examines the sources of such profitability. Momentum portfolios are significantly profitable in the intermediate term in Hong Kong, but the profits become insignificant after risk adjustment by the Chordia and Shivakumar (2001) model. The stock-specific return strategy and factor-related return strategy are analyzed to examine which portion of the total return causes stocks to enter extreme portfolios. The Chordia and Shivakumar factor-related return strategy obtains profits with a magnitude that is close to that which is attained by the total return momentum strategy. Additional evidence further supports the view that the Chordia and Shivakumar model captures momentum profits.  相似文献

To understand the link between inequality and development, a decomposition of the Gini index by income sources is used that emphasizes the role of three components measuring the impact of the shares of the sources, the degree to which they are unequally distributed, and their correlation with total income. Such a breakdown explains why the rising section of the Kuznets curve is mainly the consequence of the increasing share of wages while its declining section reflects the decreasing share of entrepreneurial income and the negative correlation between transfers and total income. The data sources were provided by the International Labour Office.  相似文献

Using the tripartite model of attitude structure as a conceptual basis, this article investigates voter attitudes toward presidential candidates, including cognitive and affective assessments of these leaders as well as behavioral intentions and voting behavior. Data collected from the seven most recent U.S. presidential elections were used to compare Democratic and Republican Party candidates who were successful in securing votes to those who were unsuccessful. Here, follower perceptions of leader intelligence, feelings of pride and hope, as well as feelings of fear and anger were found to be statistically different between the two groups. Additionally, regression analysis using follower assessments of candidates' leadership quality, as dependent upon certain perceptual traits of that leader, are presented. Candidates perceived to be higher in intelligence, considered to possess stronger degrees of inspirational quality, and judged more “likeable,” in terms of generating stronger degrees of positive follower affect and lower degrees of negative follower affect, are considered better quality leaders. Followers' perceptions of these traits are found to be key predictors of whether that follower will consider a leader to be of high quality.  相似文献
