Definitive evidence regarding a rapid mean reversion of the real exchange rate is not present when using standard linear methodology, including unit root tests and fractional integration. To consider the robustness of these results, we use an encompassing model, the Gegenbauer AutoRegressive Moving Average (GARMA) model, which nests as special cases the existing linear methods. The GARMA model accommodates a complete notion of persistence and allows shocks to dissipate slowly in a cyclical manner. We find evidence supporting a weak version of purchasing power parity, where equilibrium errors are long memory with strongly persistent cycles. However, this new form of cyclical mean reversion is likely too slow to be economically meaningful. The inability to find a strong equilibrium attractor process, using a very general encompassing linear methodology provides support for the recent models that allow for a nonlinear attraction process and for shifting real exchange rate equilibria.  相似文献

Despite the call for increased theoretical diversity in franchising research, the incorporation of organizational theory into this literature has been minimal. In response, we examine how aspects of organizational identity are represented in franchisee recruitment Web sites. We develop the concept of franchise branding to understand how franchisors position franchise opportunities to attract potential franchisees. We find that firms in the Franchise 500 use more language associated with market orientation, entrepreneurial orientation, and charismatic rhetoric when compared to a sample of lower-performing franchises. We also examine the impact of franchisor size and age to examine how liabilities of size and newness impact language use. We find that larger firms tend to use more rhetoric but detect no significant differences based on age. We conclude by discussing future possibilities for incorporating additional theoretical perspectives into the franchising literature.  相似文献

We report on lessons and insights concerning an interview-based, qualitative research thesis undertaken by an honours year university student in actuarial studies, who had no previous experience with qualitative research. Motivations and the need for research of this nature are provided in depth. Observations are presented on key areas of the research process, from the perspective of both research student and supervisors. This informs future students who may be considering qualitative research, who have not previously engaged in this approach. It also informs supervisors in predominantly quantitative disciplines who may be unfamiliar with some of the nuances of interview-based approaches.  相似文献

The correlation structure of asset returns is a crucial parameter in risk management as well as in theoretical finance. In practice, however, the true correlation structure between the returns of assets can easily become obscured by time variation in the observed correlation structure and in the liquidity of the assets. We employed a time‐stamped high‐frequency data set of exchange rates, namely, the US$–deutsche mark and the US$–yen exchange rates, to calibrate the observed time variation in the correlation structure between their returns. We also documented time variation in the liquidity structure of these rates. We then attempted to link the observed correlations with the liquidity via an application of an illiquid trading model first developed by Scholes and Williams (1976). We show that the observed correlation structure is strongly biased by the liquidity and that it is possible to effect at least a partial rectification of the otherwise downward‐biased observed correlation. The rectified sample correlation is, therefore, more appropriate for input into models used for forecasting, option pricing, and other risk management applications. © 2001 John Wiley & Sons, Inc.

This article introduces endogenous institutional changeinto a neoclassical growth model. For some parameter values,all Markov perfect equilibria involve a shift from common propertyto private property followed by a shift back to common property.Even in the presence of a linear production technology, thissequence of switches generates growth rates that are increasingat low levels of capital and decreasing at high levels of capital.This result rationalizes the hump-shaped growth path followedby some countries through history, as well as the conditionalconvergence observed in postwar data. For other parameter values,there are also equilibria in which common property prevails forever.This result rationalizes the low-growth traps in which many poorcountries find themselves.  相似文献

Catastrophic mortality events are characterized by a sudden and concentrated increase in mortality and as such present a major risk to life insurers. Such events include pandemics, war, natural disasters, terrorist attacks, and industrial, transport, and other accidents. Of these, pandemics arising from influenza are considered the most significant threat to the life insurance industry due to their capacity to cause a major increase in claims. We review the features and mortality implications of an influenza pandemic for life insurers, and describe a range of other risks that are likely to emerge as well.  相似文献

The e-government movement advocates increased use of technology to improve government efficiency and reduce corruption by reducing the discretionary power of government officials. This paper studies the relationship between improvements in inspection technology within a Principal-Supervisor-Agent model, where the supervisor is an inspector who is hired by the principal to investigate the agent’s potentially illegal actions. We show that when technology increases the marginal or total productivity of the supervisor’s effort, improvements in inspection technology encourage some types of bribery. Although such technological improvements induce an equilibrium with bribery, compliance and social welfare can still rise. However, when technology and supervisory effort are sufficiently substitutable, improvements in technology may reduce compliance when bribery occurs in equilibrium even when those same technological improvements would have raised compliance in the absence of bribery. We also characterize the relationship between the principal’s socially optimal technology and the anti-corruption policy available to the principal and find that the socially optimal inspection technology may be a substitute for or a complement to the anti-corruption policy. Finally, we show that for any set of policies that optimally induces a no-bribe equilibrium, there exists another set of policies that induces an equilibrium with bribery that is pareto superior to it.  相似文献

Over the past decade, the exponential growth in Professional in Human Resources (PHR) and Senior Professional in Human Resources (SPHR) certifications awarded by the Human Resource Certification Institute substantiates the need to reexamine the base rate of HR job announcements that require or prefer such certification. Based on a sample of Web‐based job announcements in 2002, Aguinis, Michaelis, and Jones (2005) reported that only 1.4 percent required or preferred PHR/SPHR certification. Using a similar design, the current study found that 15.6 percent of job announcements required or preferred PHR/SPHR certification, which is nearly 11 times the rate found in the Aguinis et al. (2005) study. Results also suggested the demand for PHR/SPHR certification was positively related to experience, educational level, and job title level, with the base rate reaching 25.1 percent for managerial HR roles.  相似文献
