The view that Australian protection discriminates against the less developed countries (LDCs) is examined in this paper. It distinguishes between direct discrimination through tariff preferences and indirect discrimination through inter-commodity differences in rates of protection. The second mechanism proves to be more important. While Australian protection did not discriminate against the LDCs in 1968–49, by 1977–78 it did. This reflects changes in the commodity composition of Australia's imports from the LDCS . 相似文献

This article deals with some aspects of the compilation of input-output tables (I.O. tables). A global view is given of the way in which I.O. tables are compiled in The Netherlands. It is indicated that in The Netherlands a number of developments are in progress that have led to an extension of the uses that are made of I.O. tables. The changing demands on I.O. tables that result from these developments can be met in future to an important degree. This has been made possible by extending and improving basic statistics and by increasing the uses made of automation facilities. Some problems remain, however, and one of these problems takes a central place in this article. This is the problem of accuracy and continuity: how can yearly I.O. tables be compiled that combine accuracy with consistency over time. Accuracy means here that the tables should be as complete as possible and in optimal accordance with all available information. Consistency over time means that estimates of details of I.O. tables compared with the same estimates for previous years reflect real economic developments. It is obvious that those two demands may conflict, particularly for years in which new information becomes available. It then must be decided whether accuracy or consistency in time deserves priority. What problems result from this decision and what are the consequences for the yearly I.O. tables? The problems arising from the conflicting demands of accuracy and continuity apply to the Netherlands in the last few years. This led to a revision of I.O. tables and national accounts for 1977. This revision resulted in an increase of estimated national income of more than 6 percent. For some components the adjustments have been much larger; this is particularly true for the services sector. More information on the 1977 revision is given in an annex. 相似文献

We show the existence of an equilibrium in a model where private goods are allocated by markets and the public good (bad) is allocated by majority rule voting. 相似文献

This paper specifies and analyzes a generalized disequilibrium macroeconomic model that explicitly includes the concept of spillover in nontatonnement financial and real markets. It is shown that the dynamic quantity and expenditure theories of income determination are special cases of the model which depend upon the degree of spillover from the bond to the commodity market. Simulation experiments designed to produce a vigorous monetary shock to the system clearly show that national product is very sensitive to the degree of spillover, and thus, the design of monetary policy within the context of gradual market clearing should consider the size of spillover. 相似文献

This paper presents an asymptotic property of a joint spot-futures market equilibrium established in Cheng-Magill (1982). As speculators diversity over a large number of markets, the equilibrium risk premium converges to an asymptotic premium, the behaviour of which depends solely on the stochastic dependence between the spot price and an index of average returns on other markets. Risk arising from the variability of the spot price itself is diversified away. The results are related to the arbitrage pricing theory of Ross (1976). 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

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
