During the 1980s, increasing numbers of developing countries unilaterally liberalized their trade regimes. This paper presents an overview of this dramatic shift from protectionism toward freer trade. South Asia, Latin America, and East Asia have implemented extensive reforms, yet each region has shown a distinct difference in approach and in the degree of liberalization actually achieved. Latin America stands out as moving sharply toward the level of openness of the East Asian Newly Industrialized Countries (NICs). Only in Africa is there little progress toward freer trade.  相似文献

Despite the predictions of several attitude change theories, most empirical research suggests that humorous communications are no more persuasive than their serious counterparts. The present study adopted a trace consolidation theory approach and tested the hypothesis that humorous appeals are more persuasive than serious appeals when time for trace consolidation is allowed. The trace consolidation theory hypothesis was supported most directly by shifts in cognitive responses. On some measures, sex differences were also observed. Specifically, males were found to be more susceptible than females to the humorous persuasive appeal.  相似文献

We use the US International Trade Commission's uniquely detailed 1995–2007 Chinese Customs data to better understand the pattern of trade between China and its two largest trading partners, Japan and the United States. Our review finds that only a small share of these flows can be characterized as arm's length, one-way trade in final goods. Instead, we find extensive two-way trade, deep vertical specialization, concentration of trade in computer and communication devices, and a prominent role for foreign-invested enterprises. While these characteristics define both bilateral relationships, important differences between the two pairs do emerge, suggesting that trade costs influence the method by which multinationals choose to integrate their production with China. Consequently, we argue that dialogue on East Asian trade liberalization should include the possibility of significant production gains for the US from its inclusion in any regional agreements.  相似文献

Abstract

Knowledge about preferences for campsite attributes is needed so that management strategies can be guided by users’ preferences for settings and experiences. However, results of campsite choice studies have shown great variability across settings. Reexamination of this research shows a hierarchical typology of attributes: most important are necessity attributes, which supply basic camping needs, followed by experience attributes, which enhance preferred experience outcomes, and finally amenity attributes, which are relatively minor but can improve site quality. A survey of Whitewater boaters confirmed the predicted order of attribute importance and generally supported the proposed definitions of attribute types. A tentative model of campsite choice is offered in which sites are evaluated first for their ability to provide necessity attributes, then experience attributes, and finally, if more than one potential site remains, amenity attributes. Constraints may cut the evaluation process short anytime after the initial (necessity attribute) stage.  相似文献

We study the merits of capped retirement products with guarantee for investors who have the flexibility to dynamically adjust their investment strategy. All contracts under consideration are fairly priced such that the net profit of the provider is zero. Without the rider, an expected utility maximizing CRRA investor does not want an investment cap. Here, she commits herself to a strategy a priori. With the flexibility rider, the optimization problem changes and the optimal strategy is a response to an exogenously set price. A fair pricing then anticipates the optimal response of the investor. We show that the maximum expected utility of the investor can, for anticipated fairly priced products, be obtained for a finite cap. Thus, a capped product design can give a Pareto improvement to the otherwise uncapped contract version.  相似文献

Recurrent tasks such as pricing, calibration and risk assessment need to be executed accurately and in real time. We concentrate on parametric option pricing (POP) as a generic instance of parametric conditional expectations and show that polynomial interpolation in the parameter space promises to considerably reduce run-times while maintaining accuracy. The attractive properties of Chebyshev interpolation and its tensorized extension enable us to identify broadly applicable criteria for (sub)exponential convergence and explicit error bounds. The method is most promising when the computation of the prices is most challenging. We therefore investigate its combination with Monte Carlo simulation and analyze the effect of (stochastic) approximations of the interpolation. For a wide and important range of problems, the Chebyshev method turns out to be more efficient than parametric multilevel Monte Carlo. We conclude with a numerical efficiency study.  相似文献

This paper addresses the usefulness of a longitudinal data file constructed from records on employers from the Michigan Employment Security Commission. We describe the main features of the data file, which includes quarterly (and in some cases, monthly) data from the third quarter of 1978 through the first quarter of 1983, plus the fourth quarters of 1983–87. We then illustrate the uses of the data with two examples: (1) studying changes in the Michigan economy, in particular the early growth and survival of new units of different sizes; and (2) studying the behavior of wages and employment following changes in ownership.Judith Connor and Steven Heeringa are primarily responsible for Section II and the Appendix, John Jackson for Section III, and Charles Brown for Section IV.  相似文献

The paper reinterprets Schumpeter's views on the dynamic effects of taxation, as originally expressed in Crisis of the Tax State, from a Kaleckian perspective. In light of Schumpeter's rejection of Keynesian and Marshallian approaches to taxation, the paper argues that a recently developed Kaleckian approach provides an appropriate basis from which to analyse the effects on the business cycle of balanced changes in the structure of taxation. It is shown that, under certain shifting assumptions, increases in the taxation of wages or profits will stimulate investment and attenuate the amplitude of the business cycle. Ultimately, the shifting of taxes reduces to a conflict over income shares. The changing distribution of income in the United Kingdom in recent years suggests that investment is likely to remain sluggish unless there is a significant reversal of income shares. This may give rise to increasing economic and political tensions into the 21st century.  相似文献
