Summary. A model that includes the cost of producing money is presented and the nature of the inefficient equilibria in the model
are examined. It is suggested that if one acknowledges that transactions are a form of production, which requires the consumption
of resources, then the concept of Pareto optimality is inappropriate for assessing efficiency. Instead it becomes necessary
to provide an appropriate comparative analysis of alternative transactions mechanisms in the appropriate context.

According to the essential features of urban economic strips, this paper is intended to point out that Chengdu-Chongqing strip has so far been an urban area in geographic or spatial sense, but not an urban economic strip in economic sense. On further basis of analyzing several problems existing in the developrnent of Chengdu-Chongqing economic strip, some countermeasures are correspondingly put forward hereafter. 相似文献

Competition was introduced into the electric utility industry with the passage of the Public Utilities Regulatory Policy Act (PURPA) of 1978. Increasing interest has appeared in structuring the PURPA purchase market into an auction system. This paper addresses the design issues associated with setting up such markets and introduces a simulation model to study them. The simulation analysis is guided by theoretical issues such as the alleged inefficiency of first-price auctions. We find that efficiency concerns raised about first-price auctions turn out to be less important than simple theoretical concerns would suggest. 相似文献

This paper integrates the analytic hierarchy process (AHP) with scenario analysis techniques to explore the commercialization of future hydrogen fuel processor technologies. AHP is a multi-attribute decision analysis tool useful for evaluating decisions with multiple criteria and alternatives. In this paper, AHP is extended using a technique called perspective-based scenario analysis (PBSA). In PBSA, scenario analysis is conducted based on potential future decision-maker perspectives that are integrated into the AHP framework. This paper discusses this method and applies it to the evaluation of hydrogen fuel processor technologies 15–20 years hence. The results provide an added layer of insight into the opportunities and barriers for the commercialization of these technologies as well as the methodological opportunities for using AHP and PBSA as a futures tool. 相似文献

On the concept of optimum population 总被引:4,自引:0,他引:4
Dasgupta PS 《The Review of economic studies》1969,36(3):295-318
The economic welfare of a community is affected by policies that determine both the rate of capital accumulation and the rate of growth of population. The optimum size of population at any point is time will depend on the size of the existing capital stock and the optimum rate of savings will depend on the existing number of people. Consequently, in this sense, a population policy cannot be developed without a concurrent savings policy. The criterion of optimality that will be used is the ma ximization of the total discounted welfare of all generations from now to infinity. The problem will be to select that rate of savings and that size of population at every moment which will achieve this maximum welfare if, in fact, a maximum exists. An inquiry is made into the existence of an optimum policy under various circumstances. An attempt is made to evaluate the consequences of various ethical beliefs. 相似文献

The attempt was made to obtain an improved estimate of the economic value of birth control programs in developing countries. A medium sized econometric simulation model -- based on data covering a cross-section of 67 countries -- was constructed to investigate the implications to a developing economy of birth prevention. Fertility measures were included in the model as important endogenous variables in the economic process, and parameter values were supplied by formal estimation rather than expert judgment. A matrix of age-specific birth and survival rates was used. The model has sufficient detail to generate a complete age distribution for the population, yielding improved estimates of the value of birth control and other growth policies. Initial focus is on the construction of the model. This is followed by simulation of the system with simulated paths compared to observed paths for a few countries. Projections of real per capita output and other variables with and without the presence of a birth control program are presented. The size of the differential economic effect associated with lower fertility is examined for 17 sets of initial conditions corresponding to a selection of 17 developing countries. Comparisons of birth control with other forms of investment are made. 相似文献

This article on the distribution of wealth among individuals in the United Kingdom presents recent work on the effects of including pension rights and the significance of sex, age and marital status. It describes the rationale for including the accrued rights in occupational and State pension schemes (funded or unfunded) and the methods of estimation used. For funded schemes the rights are valued as the accrued liability of the schemes to their members, and for unfunded schemes similar liabilities are hypothecated; these estimates of the value of accrued pension rights involve assumptions about future earnings and interest rates. The trend in average marketable wealth with age is upwards until advanced years when it slows down or slightly reverses. Adding occupational pension rights only slightly raises the trend for females but has a bigger effect for males. Adding State pension rights raises these upward trends until the age of 60 after which there is a decline. For marketable wealth on the average males are wealthier than females but less wealthy if single, divorced or widowed. Adding occupational pension rights improves the relative position of males; adding State pension rights cancels this out. The effect of marital status rises with both age and sex and therefore a detailed three-way analysis is made. For females widows are on average the wealthiest; for young males the married; for older males the single. Using Theil's coefficient of entropy for comparing the inequality of wealth, the addition of pension rights reduces inequality by two-thirds. Age accounts for only 6 percent of inequality for marketable wealth but for 31 percent if pension rights are included. 相似文献
