Models that assume bonds denominated in different currencies are perfect substitutes can not explain certain empirical puzzles: the exchange rate volatility puzzle is that these models can not explain the observed volatility in real and nominal exchange rates; the Backus-Smith puzzle is that these models can not explain the observed low correlation between real exchange rates and the ratio of home to foreign consumption; the Backus-Kehoe-Kydland puzzle is that these models can not explain the observed low correlation between home and foreign consumption; and finally, the uncovered interest parity puzzle is that these models can not explain the observed deviations from that parity. These long standing puzzles make the models harder to defend. In this paper, we present a symmetric two country portfolio balance model in which home and foreign bonds are imperfect substitutes for money in each country’s transactions technology; this of course makes home and foreign bonds imperfect substitutes for each other. Our calibrated model is capable of addressing the Backus-Smith puzzle and the Backus-Kehoe-Kydland puzzle. It does not fully resolve the exchange rate volatility puzzle, but it makes some headway. And finally it generates deviations from uncovered interest parity, though by some estimates these deviations are not large enough to be consistent with the data. 相似文献

There has been great focus in the recent trade theory literature on the introduction of firm heterogeneity into trade models.
This introduction has highlighted the importance of the entry/exit decision of firms in response to changes in trade barriers.
However, it is typical in many of these models to use iceberg transport costs as a general form of trade barriers that can
be interchangeable with ad valorem tariffs. I show that this is not always an appropriate conclusion. Specifically, I illustrate
that profit for an exporter is more elastic in response to tariffs than iceberg transport costs, which affects the entry/exit
decision of firms. This has implications for welfare analysis and empirical specifications. 相似文献

The coordination required to successfully implement supply chain initiatives suggest that supply chain management change processes may possess some unique characteristics. Yet, empirical studies are scarce to support this logic. Using an empirical design and data obtained from managers, and drawing largely from Lewin's change process conceptualization, this study compares the process of supply chain management change to non‐supply chain management change. Further investigation into monitoring and control of supply chain management change is advised. 相似文献

One path to black entrepreneurship is via the franchise. This article analyzes the basic issues of progress and success in
the development of black-owned franchise units, with a focus on the measurement and promotion of such progress and success.
Existing measures and promotional efforts are evaluated, and the perspectives of both the franchisor and the franchisee are
probed. Secondary sources of data are analyzed, as are a series of in-depth telephone interviews conducted with a sampling
of top executives of both large and small franchisor companies and also with a variety of black owners of franchise units.
Recommendations and conclusions, for both franchisors and franchisees, are presented. 相似文献

There are many situations where two interacting individuals can benefit from coordinating their actions. We examine the endogenous choice of partners in such social coordination games and the implications for resulting play. We model the interaction pattern as a network where individuals periodically have the discretion to add or sever links to other players. With such endogenous interaction patterns we see multiple stochastically stable states of play, including some that involve play of equilibria in the coordination game that are neither efficient nor risk-dominant. Thus the endogenous network structure not only has implications for the interaction pattern that emerges, but it also has a significant impact on the play in the coordination game relative to what would arise if the same interaction network were exogenous. 相似文献

Despite widespread uncertainty, if not scepticism, about the precise nature of the expertise that consultants bring to bear in their client engagements, organisations continue to employ consultants in large numbers, especially in information technology-related projects. Drawing on a participant observation study of IT/management consultancy practice, this paper seeks to explore the different ways in which consultants are seen as experts in the light of the pressures of the consultancy market place. The ongoing construction of consultancy expertise through the interaction of consultants and their clients with an array of elements, including technical knowledge, skilled practice, individual and collective experience, and commercial interests is discussed. It is suggested that, rather than being a relatively-enduring property of individuals, based on their mastery of a body abstract knowledge or their skills at managing the perceptions of their clients, the precarious and multi-faceted character of their expertise means that consultants are continuously engaged in its active construction through their situated practice. 相似文献
