We evaluate and qualify Friedman's, 1953, “case for flexible exchange rates” in the presence of sticky prices in a two country
model. We find that a flexible regime performs indeed better when the degree of nominal price rigidity is high while a bilateral
peg does better when prices are fairly flexible. This result obtains independent of whether monetary policy is activistic
or not and is mostly due to the negative relationship between employment and productivity shocks when prices are relatively
sluggish (Gali, 1999). A unilateral peg tends to produce the lowest level of world welfare but it sometimes represents the
best monetary arrangement for the pegger.

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

Previous studies on strategic groups have mainly focused on their static characteristics in order to test the theory of strategic groups and intraindustry performance differences (Porter, 1979; Cool and Schendel, 1988; Fiegenbaum and Thomas, 1990). In contrast, this study takes a longitudinal, dynamic perspective and describes the forces driving strategic group membership and structural evolution. It proposes that a strategic group acts as a reference point for group members in formulating competitive strategy. A partial adjustment model of strategic mobility is then developed which incorporates the idea of a strategic group as a reference group. It models strategic change in an industry both within and across strategic groups. The model is tested in the context of an in-depth industry analysis of the more significant firms in the insurance industry over the 1970-84 time period. The results suggest that strategic groups act as reference points for firm strategies and that predictions of future firm strategies and industry/group structures may also be successfully derived. 相似文献

The purpose of this study was to explore evidence of gender-based vicarious sensitivity to disempowering behavior in organizations, expanding the concept of hostile working environment beyond the context of sexual harassment. Male and female graduate and undergraduate students viewed 10 video segments of Anita Hill's interview by U.S. senators during the October 1991 confirmation hearings of Supreme Court Justice Nominee, Clarence Thomas. Although no significant relationship was found between the personal attributes of age and ethnicity to perceptions of disempowering behavior, female participants reported seeing significantly more offensive behavior in the video segments than did male participants. The results are discussed in terms of greater female sensitivity to common forms of disempowering behavior in organizations, and having a disparate negative impact and systematically placing women at a disadvantage in today's workforce. 相似文献

Entrepreneurs and the Process of Obtaining Resources 总被引:1,自引:2,他引:1
This paper examines the process of how entrepreneurs assemble resources. In the model, the entrepreneur's challenge is to convince two complementary resource providers to commit their resources to a new venture. Before committing their resources, one of them needs to perform a costly evaluation. The entrepreneur has a problem with getting sufficient attention, because each provider has an incentive to wait and free-ride on the other's evaluation. For some parameters the entrepreneur solicits both partners with equal intensity ("knocking on every door"); for others, the entrepreneur always solicits the same partner ("pestering"). For many but not all parameter ranges, the process of assembling resources takes too much time relative to what is socially efficient. The model thus explores what factors facilitate or hinder the creation of new firms. 相似文献

Based on economic methodology we model an ecosystem with two species in predator–prey relationship: mice feed on grain and grain feeds on a resource. With optimizing behavior of individual organisms a short-run ecosystem equilibrium is defined and characterized that depends on the farmer's use of fertilizer and pesticide and on the mice population which, in turn, is affected by pesticides. In that way, a microfounded agricultural production function is derived. Linking a sequence of short-run ecosystem equilibria yields the growth function of the mice population which is thus derived rather than assumed. In each period the farmer harvests all grain in excess of some given amount of seed. If she maximizes her present-value profits, optimal farming is characterized by either using no pesticide or a moderate amount of pesticide or by applying a chattering control. Pest eradication is never optimal. On the other hand, if the farmer takes into account steady-state mice populations only, it may be optimal to eradicate mice or to use no or a moderate amount of pesticide depending on prices as well as on the shape of the grain production function which is determined by microparameters of grain reproduction. 相似文献

Group decision-making: Head-count versus intensity of preference 总被引:1,自引:0,他引:1
This paper puts forth a framework for reshaping the group decision-making process. The proposed framework extends from the usual one-issue-at-a-time decision-making to one that involves several related issues simultaneously. Weaknesses of the traditional majority voting mechanism are first identified, and then a different voting method that takes each individual voter's sentiment into account is discussed. Specifically, a decision-maker is asked to express his/her intensity of preference for the issues encountered. Three hierarchical structures—benefits, costs, and risks—are developed to evaluate the alternatives. Due to the nature of pairwise comparisons and synthesis, the proposed method is amenable to consensus building and has higher reliability and consistency. It can be used for candidate selection, e.g. governmental election, when a large population is involved. It is also effective for resource allocation and prioritization when a small group or business is concerned. We believe the proposed approach has potential for resolving deficiencies of the conventional voting mechanism, and can be applied to many real-world problems. Its implementation on the Internet is also discussed. 相似文献

Prior research has employed a number of methods to test for speculative bubbles in asset prices, including a method based
on the concept of duration dependence. This study explores whether duration dependence tests for speculative bubbles are sensitive
to specification decisions. Our results question the efficacy of using measures of duration dependence to test for speculative
bubbles. In particular, we find that evidence of duration dependence is sensitive to the method of correcting for discrete
observation of continuous duration, the use of value-weighted versus equally weighted portfolios, and the use of monthly versus
weekly runs of abnormal returns. (JEL C41, G12) 相似文献

An empirical test of trust-building processes and outcomes in sales manager-salesperson relationships 总被引:1,自引:0,他引:1

This study examines three trust-building processes and outcomes in sales manager-salesperson relationships. This study, based
on a sample of more than 400 business-to-business salespeoples from a variety of industries, shows two trust-building processes
(predictive and identification) to be significantly related to salesperson trust in the sales manager. Interpersonal trust
was found to be most strongly related to shared values and respect. Trust was directly related to job satisfaction and relationalism,
and indirectly related to organizational commitment and turnover intention.
