This article deals with goal programming as an aid to resolving transportation problems. The objective of this study is to demonstrate the use of goal programming as an approach to reducing total cost in transportation problems that possess variable supply and demand requirements. A generalized goal programming model is formulated and applied to a series of transportation problem situations based on the empirical data provided by a medium-size trucking firm. Comparison of the results demonstrates the cost advantage of using the goal programming model in place of the transportation method and integer interval linear programming. 相似文献

Using a stylized oligopoly model, we analyze the effect of cartel deterring fines, taking into consideration exemptions granted to cartel members cooperating with the competition authorities. We conclude that the fines can act as a deterrent to breaking collusive agreements, thus stabilizing the cartel. 相似文献

In this article, a new numerical procedure is used to compute the equilibrium of a vintage capital growth model with nonlinear utility, where the scrapping time is nonconstant. We show that equilibrium investment and output converge nonmonotonically to the balanced growth path due to replacement echoes. We find that the average age of capital is inversely related to output, which is consistent with recent micro evidence reinforcing the importance of the embodied question. We also find that an unanticipated permanent increase in the rate of embodied technological progress causes labor productivity to slowdown in the short run. 相似文献

The Loan Guarantee Scheme was initiated in 1981 in order to alleviate a perceived constraint in the ability of small firms to secure bank finance due to a lack of collateral. This paper shows that a national small firms support scheme has, at the point of delivery, had quite different coverage across regions. Briefly, the initial evidence suggests that the Northern regions of England have been the major net beneficiaries of the scheme, primarily at the expense of Northern Ireland and Scotland. Further analysis identified house prices as the single most important determinant of loan size, acting via a collateral effect. On loan numbers and value, fixed regional effects were dominant particularly in the South East and North West. 相似文献

This paper develops a tractable, heterogeneous agents general equilibrium model where individuals have different endowments of the factors that complement the schooling process. The paper explores the relationship between inequality of opportunities, inequality of outcomes, and aggregate efficiency in human capital formation. Using numerical solutions we study how the endogenous variables of the model respond to two different interventions in the distribution of opportunities: a mean-preserving spread and a change in the support. The results suggest that a higher degree of inequality of opportunities is associated with lower average level of human capital, a lower fraction of individuals investing in human capital, higher inequality in the distribution of human capital, and higher wage inequality. In particular, the model does not predict a trade-off between aggregate efficiency in human capital formation (as measured by the average level of human capital in the economy) and equality of opportunity. 相似文献

In Belgium, financial and industrial groupings play a crucial role in the accumulation and allocation of capital in the economy. In this paper, it is hypothesized that Belgian firms for which investment is partly financed on an internal capital market, will not be subject to financing constraints to the same extent as firms which have to borrow from banks. Moreover, it is hypothesized that firms belonging to a group, transfer internal surpluses of funds to other group members by investing in financial assets. An empirical analysis confirms the first hypothesis, but rejects the second hypothesis. 相似文献

Mining cycles have had an enormous impact in the evolution of the localisation of economic activity, in particular of industry, in Chile. The nitrate cycle was characterised by a labour‐intensive extraction process and activity which was geographically very concentrated. The copper cycle was geographically more dispersed and its activity more capital‐intensive. We stress the role played by the State in the latter de‐concentration due to the impact of regional development policies and assess the importance of factor endowments and agglomeration economies, in the localisation of the manufacture. 相似文献

This paper proposes four criteria for the selection of a better measure of living standards: it should be comprehensive, correlation sensitive, preference based, and fairness based. These criteria are applied to the following measures: income, equivalent income, capabilities, and satisfaction. The paper then explores the relationship between the space of goods and services, the space of budgets, and the more fundamental space of the aspects of life that people really care about. The importance of the fairness principles guiding interpersonal comparisons is highlighted. 相似文献
