This paper looks at the ways in which air transport has affected economic growth in metropolitan areas in the Asia-Pacific region. Two primary influences are identified: level of service to a particular airport; and local airline industry activities. The paper examines the former by means of an historical overview of the factors influencing the development of economic 'control centers' in the Pacific Rim. The level of a service at an airport in the region has depended greatly on local economic activity, as well as on geography, aircraft technology, and intergovernmental regulation. Data on non-stop international flights in the Asia-Pacific region for 1970, 1980, and 1990 are used to document the emergence of major hubs such as Hong Kong, Los Angeles, and Tokyo. It is argued that as technology advances, services will become even more concentrated in a few places, causing further congestion and strain on infrastructure capacity.  相似文献

This paper presents the results of a survey on the capital investment practices of large corporations in Malaysia, Singapore and Hong Kong. Our findings are fairly consistent with those from similar U.S. surveys. However, Malaysia, Singapore and Hong Kong companies seem to use multiple techniques, both simple and sophisticated, in evaluating investment projects, while U.S. companies appear to make great use of discounted cash-flow rate of return. Although Malaysia, Singapore and Hong Kong companies often make annual cash-flow forecasts over the life of a project, they do not undertake much analysis of risk involved in the project. Moreover, there is room for improving the practice of project implementation, the post-audit of implemented projects, and the use of post-audit data.Dr Wong Kie Ann is with the School of Management, National University of Singapore; Dr Edward J Farragner is with the Department of Finance, DePaul University, U.S.A.; and Mr Rupert K.C.

This paper examines allocations of industrial milk quota across provinces in Canada under two hypothetical scenarios. The study focuses on the case where considerable reallocation of production occurs across farms and provinces due to changes in the distribution of quota holdings. The allocations are determined using linear programming (LP) analysis, where the objective of the optimization problem is to minimize the delivered cost of products such as cheese, butter, ice cream, and yogurt. The LP model seeks to meet provincial targets for domestic disappearance on a milk-equivalent basis in the short to medium term, where limits are imposed on the maximum achievable growth of production and processing capacity in any one I he conclusions are that reallocation of existing quota across farms and provinces has a potential to reduce considerably the costs of industrial milk production and the cost of transporting manufactured products.  相似文献

Conclusions The presence of young children decreases women’s labor supply as shown by the LFPRs for women with young children (which are always considerably lower than those for women without young children). Also, the number of young children is almost always negatively related to annual hours of labor supplied (significantly so in half the regressions). Black and white women are found to have an inelastic labor supply, but with increasing elasticity from 1969 to 1974. There is a statistically significant difference in the estimated regression coefficients of the labor supply model for black and white married women in 1969 and 1974 in both the arithmetic and logarithmic forms. The husband’s earnings are significantly negatively related to white married women’s annual hours of work in 1974, while the relationship is not significant for black married women. Crosselasticity terms show that white married women decrease their annual hours of work in response to an increase in husband’s earnings to a greater extent than black married women in 1971 and 1974. These results are consistent with the hypothesis that black women do not rely on their husband’s earnings to as great an extent as white women.  相似文献

This paper presents the results of a micro study of the influence of the shift differential factor on utilization rates in Kenyan manufacturing. Qualitative information about the nature of technology and of shift differentials is incorporated into models of the choice of utilization rate under the alternative assumptions of constant returns to scale and increasing returns to scale. Econometric tests are then used to show that 1971 data is consistent with the theoretical predictions, although the results suggest that the quantitative significance of the shift differential factor in causing excess capacity should not be overstated.  相似文献

This paper presents a model of entrepreneurial wealth maximization for the pricing of initial public offerings (IPOs). It is an extension of one previously presented in the literature. The model shows that personal tax rates on ordinary income and capital gains may, in part, determine IPO pricing: an increase in the capital gains tax rate should lower the degree of underpricing. An empirical analysis of the effect of the Tax Reform Act of 1986, which raised the capital gains tax rate, shows that the average degree of underpricing did decrease as predicted, and that this occurs after controlling for other possible influences.  相似文献

This study evaluated consumer behavioural patterns in relation to meat products, with special reference to the African sharptooth catfish, in the Northern Province. Personal interviews were conducted in rural Ga‐Mamphaka and urban Giyani. The major meat type purchased was found to be chicken (71 per cent in the rural and 46 per cent in the urban community). The sharptooth catfish was found to be acceptable to the majority of respondents, both urban (69 per cent) and rural (57 per cent). Most respondents also indicated that they would like to purchase canned catfish. A potential market for catfish would seem to exist at a price competitive with that of chicken.  相似文献

This article uses data from a 1992 survey of manufacturing enterprisesin Ghana to describe the importance of apprenticeship in themanufacturing sector and analyze the structure of the contractsin which apprenticeship takes place. The article presents threemajor findings. First, the training of apprentices is both awidespread activity and a part of the training of a large fractionof entrepreneurs and manufacturing workers. Second, two primarytypes of contracts are apparent in the data: those in whichapprentices pay fees for their training and those in which theydo not. Third, for those firms training apprentices, the choiceof contract type is strongly correlated with other characteristicsof the firm, particularly its use of credit. Apprenticeshipfees are one among many informal sources of firm finance.  相似文献
