Optimal control theory is used to analyze the implications of the adoption of price and LDC export revenue stabilization objectives by an international buffer stock for cocoa. The results obtained for the period 1956–76 suggest that the stabilization of either price or revenue at systematic trend would reduce the instability of both variables from that during the sample period. Although the stabilization of revenues at systematic trend decreases their average level, the stabilization of price has the opposite effect. Because of this, it may be financially feasible for the LDCs to provide the necessary resources for a price-stabilizing buffer stock.  相似文献

Economists have concentrated on aggregate economic growth to measure countries' development progress and in recent years have also considered income distribution performance. This paper reverses the conventional emphasis by placing income distribution at the forefront. I examine what is known about the distributions of income and poverty in the developing countries of the world and probe the correlations between poverty, inequality, and development. I explore the main sources of inequality and the extent to which individual countries have managed to alleviate poverty and reduce inequality in the course of economic growth. Employing evidence from case studies of six developing nations. I suggest some explanations for differing patterns of development and call for development planning founded on a firm commitment to helping the poor.  相似文献

During the past few years, the international agencies have been playing down economic growth as the main road to the elimination of poverty and emphasizing the role of asset and income redistribution. The latest reflection of this attitude is the so-called “basic needs” approach. This essay attempts to demonstrate that where economic growth has been sufficiently high and sustained, it has been a powerful means of alleviating poverty. Growth has not “failed”; there is simply not enough International agencies should be cautious in advocating redistribution, for the results .  相似文献

Changes in the discovery of U.S. spatial milled rice prices due to the shift from stable economic conditions and government policy of supply control in the 1960s to the more variable economic conditions and market-oriented rice farm policy of the 1970s are investigated. Efficiency of the markets was evaluated in terms of the magnitude and speed of price adjustments over three different time periods. The efficiency of the price discovery process is of concern to policymakers because firms must receive price signals quickly and accurately in order to use their resources optimally.  相似文献

The developing economies have been advocating the indexation of the prices for their primary commodity exports by tying such prices to other relevant international prices, such as the prices of imports to the less-developed countries. We have used econometric models to simulate a program of indexation of the prices of the ten UNCTAD core commodities at their 1963 levels for 1963–1975. The results suggest definite difficulties in such a program. Most notably the order of magnitude of the costs of buffer stock operations and financing is likely to be prohibitive. Also the distribution of benefits and losses among the less-developed countries is quite arbitrary. Therefore we are very skeptical about indexation by buffer stock operations.  相似文献

In formulating empirically tractable, economywide models, researchers are often forced to employ “convenient” functional forms. These forms embody restrictive maintained hypotheses. Alternatively, flexible functional forms may be utilized in a partial equilibrium setting. Estimation and incorporation of flexible functions into computable general equilibrium models is considerably more demanding of research resources. Assuming that shortcuts will continue to be necessary for researchers attempting to respond to current policy problems, this paper compares these two alternatives. Specifically, a general equilibrium model for New York State is employed to evaluate the relative performances of flexible partial equilibrium models and their more restrictive, general equilibrium counterpart. In the particular application considered, the former approach is found to dominate the latter.  相似文献

The LINK system of world trade is used to examine present tendencies toward protectionism. In protectionist scenarios we increase the prices of manufactured imports into 13 LINK-OECD countries by 5, 10, and 20 percent respectively, for 1978–1979. If a country's import equations do not depend significantly on relative price, we impose corresponding quantitative import restrictions of 5, 10, and 20 percent. Smaller OECD countries, developing countries, and socialist countries are assumed to be nonprotectionist in these scenarios. The discrepancies between the values of leading variables in the protectionist scenarios and in a baseline case show the effects of the different degrees of protectionism assumed. The results describe and validate Adam Smith's principles of the gains from free trade.  相似文献

Self-sufficiency and free trade are two of the most frequently advocated foodgrain policies. This paper presents a methodology for simulating the impact of thse two policy alternatives on a country's production, consumption, farm price, retail price and trade of a staple foodgrain. Simple formulas are also derived for estimating the effect of different policies on consumer and producer welfare. A simulation of the two policy alternatives is conducted for the case of rice in the Dominican Republic.  相似文献

This paper presents a system analysis approach for the investigation of the most effective agricultural and nutrition-intervening programs for improving the nutritional standards of the rural poor in a lesser developed country. The research is framed within a four-stage process. First, by means of observation, stylized patterns of nutritional status, food consumption, autoconsumption, and crop production are inferred. Second, based on previous anthropological case studies and statistical surveys, a theoretical model of the peasant household is specified. Third, the model is validated by comparing its empirical solution with the observed patterns. Fourth, the model is used to illustrate a method for evaluating alternative programs for improving the nutritional intakes of peasants. Programs appraised are credit for agricultural production, policies for affecting corn prices and input prices, and programs for subsidizing purchases of foods.The empirical study is about the peasant economy of Puebla in Mexico. The major foods of the typical diet and crop pattern of this area are corn (an energy food) and beans (a protein food). This diet is representative of other areas in Mexico and Central America.  相似文献

The paper develops a methodology for designing and evaluating the performance of emergency stocks. The system is required to meet consumers' demands in all emergency situations at a given level of reliability and least possible costs. The model takes into account the various stochastic elements that determine the performance of the system, including the frequency of emergency situations and their expected duration, the pace of replenishing the stocks, the consumption rate in an emergency situation, and the opportunity for stock building prior to the occurance of an emergency on the basis of advance information about the severity of the strategic situation.  相似文献

We examine the effects of the U.S.-Japan trade restraint on automobile prices and quality upgrading, for both Japanese imports and American small cars. From April 1981 to April 1984 the suggested retail price of all Japanese models increased by 15.8 percent, or 5.3 percent per year. We find that nearly the entire amount of this rise can be explained by the upgrading of individual models. This upgrading may benefit consumers who would purchase a luxury import in any case, but harms those who desire the basic imports. In addition to upgrading, we conclude that a second cost of the trade restraint has been to prevent the yen depreciation from being passed onto American consumers, in terms of lower imported auto prices. For U.S. small cars we find a 9.1 percent rise in the suggested retail price, or 3 percent per year, with a fraction of this amount due to model upgrading. If the yen depreciation had led to lower import prices without the trade restraint, then we expect that U.S. auto prices would have been lower, too.  相似文献

We present in this paper a computational model of world production, trade, and employment that is disaggregated by country and sector and report on the application of the model to the changes in tariffs and quantifiable nontariff barriers negotiated in the Tokyo Round that was concluded in 1979. The model incorporates supply and demand functions and market-clearing conditions for 22 tradable industries, plus markets for 7 nontradable industries, in each of the 18 major industrialized countries and 16 major developing countries. The equations of the model are presented in the text and the explicit functional forms in an appendix. The implementation of the model is discussed briefly.Application of the model to the Tokyo Round suggested that there will be small but beneficial effects on trade, domestic prices, and economic welfare in practically all the major industrialized countries and in some of the major developing countries. Because many of the NTB codes negotiated in the Tokyo Round were stated in advisory terms, their impact cannot be evaluated unambiguously at present. Further, many existing NTBs of importance were exempted altogether from the negotiations. The Tokyò Round must be viewed accordingly as having dealt with a somewhat limited part of all interferences with trade.  相似文献

This paper develops bureaucratic response functions within a “deviation from trend” econometric model to determine those factors that were related to fluctuations in aggregate investment finding and in the sectoral distribution of that aggretate during 1960–1975. Investment in buildings and investment in machinery are analyzed separately. On the national level, investment funding is found to respond to indicators of well-being, plan targets, bottlenecks, and foreign trade variables. Sectoral investment funding is based mainly on priority considerations.  相似文献

Exports of manufacturers from newly industrializing countries have increased dramatically in recent years. Yet, in the importing countries—largely the highly developed, “old” industrial countries—the NICs' exports constitute even now an almost insignificant proportion of total imports of manufacturers. Is there, then, some particular reason why the exports concerned seem to be strongly resented by the importing countries, and particularly likely to be faced with trade barriers? The paper examines this issue, and identifies four possible sources of demand for such protection: (1) the factor content of the NICs' exports—specifically, their relative intensity in unskilled and semiskilled labor; (2) the nature of the exported goods, which consist largely of final consumer goods rather than of machinery and equipment; (3) the NICs' lack of retaliatory power; and (4) the context of a relatively stagnant world economy, suffering from high unemployment, which the expansion of manufactured exports from the NICs has had to face.  相似文献

A general equilibrium model that is applicable for simulating the directions in which resources would be reallocated under alternative trade regimes, in particular, a free trade regime, is developed and applied to the Turkish economy. Because of the likelihood that Turkey will gain full entry into the EEC, the model is also used to identify sectors in which Turkey may have a comparative advantage relative to the EEC countries and to estimate magnitudes of static gains from full entry. To provide some tests of important generalizations from the theory of customs unions, these estimates of static gains are compared with some estimates of total welfare effects of the entry of the United Kingdom into the EEC.  相似文献

An earned family income distribution model for Massachussets is described. This model could be estimated and used for other national or subnational regions for which the micro data required to generate earned family income distribution at working period rates are available. The model is distinguished by its explicit inclusion of male- and female-headed families without earnings and by its attention to employment structure, labor market conditions, and wage acceleration. There is presented a policy simulation that shows the effects on earned family income distribution of cutting the Massachusetts corporate profits tax and offsetting the lost revenue with a luxury goods sales tax.  相似文献

A modification of optimal control for an economy under uncertainty, by splitting the technique into a simulation phase and a control phase, makes policy optimization feasible for large-scale nonlinear models. The advantages of this approach in a policy search are clearly illustrated by an application to Dutch economic planning. A historical analysis shows that it is important to treat unemployment and the balance of payments as the key targets. That dual target strategy, worked out for the current planning period, leads to economic expansion and employment creation rather than retreachment.  相似文献
