I examine the varying responses of countries to foreign trade and direct investment liberalization on spatial concentration of their economic activity by taking into consideration moderating factors such as their market size and level of economic development. I argue that liberalization increases the concentration under normal conditions but large market size, and underdevelopment can disperse economic activity. Using data from 168 countries for the period of time starting in 1980s, I found support for all hypotheses. 相似文献

The present study contributes to the literature on multiple store patronage in two important directions. First, it examines whether consumers׳ perceived importance of store characteristics have effects on multiple store patronage. Second, it examines the relationship between multiple store patronage and consumers׳ share of wallet at the primary store. Our results show that consumers who attach high value to sales promotions are more likely to visit multiple stores. However, store characteristic factors generally did not exert significant effect on multiple store patronage. Furthermore, we find that multiple store patronage and share of wallet are not interdependent and the profiles of consumers in terms of them do not share many common characteristics. 相似文献

随着我国加入WTO进行的加快,商业银行上市已是大势所趋,日益激烈的竞争加剧了我国金融业的系统性风险。目前商业银行的风险监管和救助主要依靠的中央银行和“最后贷款人”制度,这不利于推进政府市场的金融改革的宏观调控,因此,我国应借鉴发达国家的经验,尽快建立存款保险制度。 相似文献

Public capital, endogenous growth, and endogenous fluctuations 总被引:1,自引:0,他引:1
Cazzavillan [Cazzavillan, G., 1996. Public spending, endogenous growth, and endogenous fluctuations. Journal of Economic Theory 71, 394–415] studies a discrete-time, one-sector endogenous growth model with a flow of publicly enjoyable goods and productive services financed through income taxation. He demonstrates how equilibrium paths are indeterminate, for a large range of the consumption externality of public spending. This study extends [Cazzavillan, 1996] by considering an otherwise identical production function, except with public capital stock as an input. The results support the robustness of multiple growth paths even in a one-sector growth model with public capital stock, and modify the set of the consumption externality of public spending, in determining growth dynamics in a similar model with non-accumulated public spending. 相似文献

We consider an extension of the Markowitz mean–variance optimization framework to multiple return and risk scenarios. It is well known that asset return forecasts and risk estimates are inherently inaccurate. The method proposed provides a means for considering rival representations of the future. The optimal portfolio is computed, simultaneously with the worst case, to take account of all rival scenarios. This is a min-max strategy which is essentially equivalent to a robust pooling of the scenarios. Robustness is ensured by the noninferiority of min–max. For example, a basic worst-case optimal return is guaranteed in view of multiple return scenarios. If robustness happens to have too high a cost, guided by the min–max pooling, it is also possible to explore other pooling alternatives. A min–max algorithm is used to solve the problem and illustrate the robust character of min–max with return and risk scenarios. We study the properties of the min–max risk–return frontier and compare with the potentially suboptimal worst-case where the investment strategy and the worst case are computed separately. 相似文献

To secure their membership in a popular group, individuals may contribute more to the group's local public good than they would if group formation were exogenous. Those in the most unpopular group do not have this incentive to contribute. This may result in substantial differences in individual effort level between groups. Our model thus provides one explanation for the existence of group‐specific behavioral norms. A principal will prefer exogenous or endogenous group formation depending on whether he prefers high or low levels of the local public good. We analyze two stylized examples: social interaction in schools, and multiple‐task teamwork. 相似文献

We propose a rational expectations framework for understanding speculative hyperinflations that end in response to ‘orthodox’ stabilization programs. Motivated by a strong degree of hysteresis in the stock of real balances after the end of hyperinflations, we provide a cash-and-credit model in which the money demand exhibits persistence because individuals can establish long-lasting credit relationships. We use the model to show that if hysteresis in real balances is possible then a fiscal–monetary reform that successfully stops a speculative hyperinflation may fail to prevent it. We argue that speculative hyperinflationary equilibria are consistent with some key stylized facts observed in extreme hyperinflations. 相似文献

This paper deals with the phenomenon of clearance sales of fashion type goods which have an intertemporal aspect similar to durable goods. Using the Van Praag and Bode (1992) model, the case of clearance sales in a store selling more than one commodity is analyzed. Conditions and rules of thumb are shown in which it is optimal to increase the price of one product while decreasing the price of another. A linear demand model and a numerical example are presented, showing that the price of one product decreases while the price of the other product may increase or decrease in different periods. 相似文献
