在系统分析了区域交通与土地利用特征的基础上,对区域交通与土地利用的相互作用机制进行了研究,并提出了区域交通-土地利用耦合系数的概念.以黄石市1996-2004年间的交通、城镇建设和耕地的用地规模进行分析,结果显示近年来黄石市的交通-土地利用存在较为密切的关系,近年来交通得到较大发展,因而耦合系数呈增长趋势.  相似文献

The patterns of daily returns in over-the-counter (OTC) stocks are examined to determine if a holiday effect exists in the OTC market. For the sample period of 1973–1989, test results provide evidence of unusually high returns on pre-holiday trading days and unusually low returns on post-holiday trading days in the OTC market. Additional analyses indicate that other documented calendar anomalies do not cause the pre-holiday effect, but the day-of-the-week effect apparently drives the post-holiday effect.  相似文献

Agriculture's importance in the process of economic growth highlights the role of sustained advances in farm production practices by improving the quantity and quality of farm products. In this context, investment in improved agricultural technology continues to be an important avenue of assistance to the developing countries. However, the increased resource pressures facing both aid donors and recipients have emphasised the need for the prior assessment of the potential benefits of aid projects to assist effective aid planning and management. Here, the main requirements are to establish viable project goals for translation into effective programmes, to predict the likely project impacts, and to evaluate the potential benefits and costs of adopting the project's outcomes. An ex ante assessment of assistance in controlling a major livestock disease in Indonesia's eastern islands is described in this paper. The annual net benefits from controlling this disease ranged between $A0.45 and $A2.5 million according to the mortality rate reduction achieved. The benefits were shared between beef producers and consumers according to the market elasticity conditions assumed.  相似文献

We examine the effect of 269 cross‐border listings on rivals in the listing and domestic markets and find that U.S. rivals experience significant gains whereas domestic rivals do not. Both competitive and information effects are important in explaining the reaction of U.S. rivals. Regarding the competitive effects, the reaction of rivals is less favorable when listings originate in developed countries and more favorable when listing firms do not have prior operating presence in the United States. Regarding the information effects, the reaction is less favorable when listings are combined with equity offerings and more favorable when the listing is the first to occur within an industry.  相似文献

Several studies estimate the demand for watching English professional football (soccer) as highly inelastic, a puzzling result given that clubs appear to possess a degree of monopoly power. We discuss weaknesses in earlier studies and offer an alternative method of assessing elasticity based on travel costs of spectators living different distances from the grounds. We find that elasticity varies across the 20 senior clubs for which data were available but in almost every case demand is more elastic than reported in the existing literature and pricing policy appears therefore to be more orientated towards profit maximisation than previously thought.  相似文献

The authors show that an increase in international borrowing increases specialization and unemployment in a small open economy that is subject to terms‐of‐trade risks. The economy has a production advantage in the export sector. However, the size of the export sector is limited by the available funds. To insure workers against income fluctuations arising from terms‐of‐trade risks, firms in the export sector offer workers a stable wage rate with the possibility of unemployment. An increase in international borrowing increases specialization in the export sector, which leads to higher unemployment when the terms‐of‐trade shock is bad. A state‐contingent price subsidy can reduce unemployment without inefficiently reducing specialization. The results are robust to the introduction of risk‐averse firms.  相似文献
