Unlike the traditional futures contract risk‐based approach to margining, new security futures contracts are margined under a strategy‐based margining system similar to that which applies in the equity options markets. As a result, these new margin requirements are potentially much less sensitive to changes in market conditions. This article performs a simulation to evaluate whether these alternative margining methodologies can be expected to produce comparable outcomes. The analysis suggests that a 1‐day settlement period will likely lead to collection of customer margins that are virtually always greater than that which its traditional risk‐based counterpart would require. A 4‐day settlement period would lead to margin requirements that both significantly under‐ and overmargin relative to a comparable risk‐based system. This study argues that exchanges may approach the preferred probability of customer exhaustion by managing margin settlement intervals. Thus, the new strategy‐based rules, in and of themselves, will not necessarily inhibit new security futures trading activity. © 2003 Wiley Periodicals, Inc. Jrl Fut Mark 23:989–1002, 2003 相似文献

Cash settlement of derivative contracts makes them susceptible to manipulation by traders who expect to close large positions upon final settlement. Cash settlement also increases underlying volatility when hedgers unwind their hedges if they have no incentives to control their trading costs. Limits on the positions that traders can carry into final settlement can be used to mitigate associated economic inefficiencies when surveillance is insufficient. This article develops a model that regulators can use to set these limits that is based upon microstructure theory. The empirical findings indicate that existing position limits are largely inconsistent with those suggested by the model. © 2005 Wiley Periodicals, Inc. Jrl Fut Mark 25:945–965, 2005 相似文献

This paper examines a simple model of North-South trade and capital flows along structuralist lines. The South can choose its growth rate, but must finance its growth in excess of its savings by borrowing from the North. The long-run consequences of this process for the process of uneven development and for Southern debt-dependence are explored. The appropriate responses to a debt crisis are considered. 相似文献

This paper examines differences in the rate and potential of firms' capability development trajectories. Capability development trajectories are the paths over which firms' capabilities change with experience and other activities. While prior research focused on factors affecting capability development rate (the fraction of the gap between a firm's current and potential capability eliminated with each unit of activity), we argue that capability development trajectories also differ in potential (the maximum capability level a firm could achieve through repeating a given set of activities over time). We develop and estimate a formal model of capability development, showing that larger underwriting projects lead to a lower rate of improvement toward higher potential capabilities, and derive implications for research on industry dynamics and the nature of competitive advantage.

ABSTRACT This paper proposes an integrative view of the marketing concept (i.e., the ability to understand and satisfy customers) and examines its prevalence and effect on competitiveness in organizations operating in an isolated and less economically developed country. The marketing concept manifests as marketing expertise, market orientation, and externally directed organizational values. Based on a sample of 86 firms operating in Fiji, the results indicate that these three mechanisms promote organizational competitiveness, thus supporting the universality of the marketing concept. These findings confirm the important role of the marketing concept in the competitiveness of firms in a less developed economy. 相似文献

It has often been claimed that a relative expansion of the service sector has a deleterious effect on economic growth. This paper uses cross-section country-level data from three decades –1960s, 1970s and 1980s – to see whether in fact this negative relation is reflected in the data. It is found that the effect is negative or positive depending on how the role of the service sector is measured, but there is a strong case that effect is in fact usually negative. 相似文献

有关收入分配与经济增长的非正统模型一般只考虑工人与资本家这两个阶级,但是近期围绕不平等问题的讨论开始关注由工资不平等和高收入人群财富增加所带来的收入分配变化。为了分析这些因素,本文建立了两个分别遵循古典—马克思主义和后凯恩斯—卡莱斯基主义的简单模型,讨论存在这样两类人时——一类是拥有资本的生产工人,另一类是公司高管、金融资本家和传统意义上的资本家——的收入分配的变化由哪些因素决定,又会对经济增长产生什么影响。 相似文献

We use 6-digit bilateral trade data to document the effect of WTO/GATT membership on the extensive and intensive product margins of trade. We construct gravity equations for the two product margins motivated by Chaney (2008). The empirical results show that standard gravity variables provide good explanatory power for bilateral trade on both margins. Importantly, we show that the impact of the WTO is concentrated almost exclusively on the extensive product margin of trade, i.e. trade in goods that were not previously traded. In our preferred specification, WTO membership increases the extensive margin of exports by 25%. At the same time, WTO membership has a negative impact on the intensive margin. Based on novel comparative statics results about how fixed and variable trade costs impact the product margins of trade, our results suggest that WTO membership works by reducing primarily the fixed rather than the variable costs of trade. 相似文献
