This study sets forth a method to calculate the passenger benefits of an international airport project and assesses the passenger benefits brought about by two international airport projects.An international airport project mainly increases the number of flights and the possibility of determining convenient timetables. It does not significantly decrease the flight time of international travel. Thus, the user benefits brought about by an international airport project cannot be expressed by the conventional concept of ‘traveling time’, which is the term generally used.In this study, the ‘Expected Value of Traveling Time’ and ‘Expected Value of Generalized Cost’ are presented as indexes to evaluate improvements in convenience brought about by international airport projects. The passenger benefits of two airport projects in Japan are measured by consumer surplus calculated from the demand function using these indexes.These indexes are accurately calculated taking into consideration factors such as scheduling connections between domestic and international transport, and so enable a grasp not only of reductions in flight time, but also of passenger benefits resulting from international airport projects, such as increases in the number of flights and reductions in the time required to make transfers during domestic travel. 相似文献

This paper analyses the population change and urbanization process in post‐war Japan. We trace the process of population concentration into urban areas, in parallel with economic development after the war. The concentration of population into urban areas can be characterized by three major metropolitan regions: Tokyo, Keihanshin (Kyoto‐Osaka‐Kobe) and Nagoya. We also show that the urbanization process of Japan in the period from 1965 to 1985 can be characterized by two spatial phenomena; firstly, the suburbanization of the existing metropolitan areas and, secondly, the spatial dispersal of urbanized areas. 相似文献

Summary. Suppose that an economic agent is
100% certain that uncertainty she faces is characterized by a particular probability measure, but that she has a fear that, with
100% chance, her conviction is completely wrong and she is left perfectly ignorant about the true measure in the present as well as in the future. This situation is often called
-contamination of confidence. The purpose of this paper is to provide a simple set of behavioral axioms under which the decision-makers preference is represented by the Choquet expected utility with the
-contamination of confidence.Received: 25 November 2002, Revised: 15 November 2004, JEL Classification Numbers:

This study examines how the demand and supply of healthcare services have responded to the expansion of health insurance coverage in Vietnam by using biyearly provincial panel data from 2006 to 2014. The results of our analysis indicate significant progress towards universal health coverage (UHC) in Vietnam, with the expansion of health insurance coverage being accompanied by increases in admissions and inpatient days. However, some concerns remain. Our findings show a positive response of supply capacity only in terms of doctors and nurses at higher‐level hospitals (provincial hospitals), and none in other relevant aspects. Moreover, we find no positive response of the number of outpatient visits. Another concern is the issue of financial protection. The decline in out‐of‐pocket payments is not significant throughout our observation period, suggesting that lowering the cost of healthcare is not straightforward and that the expansion of health insurance coverage alone cannot achieve this. We believe that the Vietnamese experience has valuable implications for other emerging and developing countries, considering that the expansion of health insurance coverage is likely to increase utilization of healthcare services significantly and that the supply side needs to be prepared for the increase. 相似文献

This paper analyzes regional determinants of the start-up ratio in the Japanese manufacturing sector. A major contribution
of this study is the comparison between high-tech and low-tech industries. The empirical results using a sample of 253 industrial
districts suggest that business density, weight of the manufacturing sector, and the average business size significantly influence
the start-up ratio in both high-tech and low-tech industries. Distinct differences between these industries were found with
regard to the effects of human capital, research institutes, and the weight of high-tech industries.

This study examines how information broadcasting through television (TV) media influences stock market activities. Consistent with the effect of TV information to attract investor attention, we find that increased information flow through TV is significantly associated with greater trading volume and larger price change. For information type, hard news from business-oriented programmes and earnings-related news strongly contributes to the attention effect, while the effect of soft news is weaker. Bid–ask spread widens for more TV information flows, suggesting that new information arrival in the market expands information asymmetry. Finally, the impact of TV is more influential for stocks with more individual shareholders than those with institutional shareholders. 相似文献

This paper examines the welfare effects of short-sale constraints in an overlapping generations model of a financial economy with heterogeneous beliefs by focussing on the case of rational beliefs in the sense of Kurz (Econ Theory 4:877–900, 1994). To measure the social welfare, we adopt a measure that is based on the ex post social welfare concept in the sense of Hammond (Economica 48:235–250, 1981), instead of the standard ex ante criterion, since heterogeneity in beliefs invalidates it. Simulation results indicate the existence of socially optimal short-sale constraints. 相似文献

This paper examines whether importing intermediate goods improves plant performance. While addressing the issue of simultaneous productivity shocks and decisions to import intermediates, we estimate the impact foreign intermediates have on plants' productivity using plant-level Chilean manufacturing panel data. Across different estimators, we find evidence that becoming an importer of foreign intermediates improves productivity. 相似文献
