This study uses univariate and multivariate unit root tests to analyze the random walk behavior of real exchange rates for the period 1979–1989. The univariate test fails to reject the random walk model, but the multivariate test indicates that part of the real exchange rates is predictable, a result supporting purchasing power parity. Further analysis of the random walk component in real exchange rates shows that it is quite persistent: for all currencies it takes about five to eight years for this shock to diminish to half its size.  相似文献

Drugs available in the market today, selected several years ago under very uncertain future scenario, have experienced a long and expensive process of research and development carried out following both a closed and an open innovation path. To support this critical selection process, we propose a Decision Support System, able to choose among different candidates the most promising drugs along their best development path. The Decision Support System, based on a real options portfolio optimization model, mapping tools, and what‐if rules as well, has been applied to a numerical example available in literature, and the research findings show interesting managerial and academic implications.

Research summary : Acquiring knowledge on a partner's pre‐existing resources plays an important yet ambiguous role in collaborative relationships. We formally model how contracts trade off productive and destructive uses of knowledge in a buyer‐supplier relationship. We show that, when the buyer's pre‐existing resources are vulnerable to the revelation of sensitive knowledge, the supplier overinvests in knowledge acquisition as it expects to use the knowledge as a threat in price negotiations. A non‐renegotiable closed‐price contract prevents such overinvestment and reduces the supplier's ability to expropriate the buyer ex post. Our results extend to the cases of renegotiable closed‐price contracts, repeated interactions between a buyer and a supplier, and the use of nondisclosure policies. We draw theoretical, empirical, and managerial implications from our model. Managerial summary : This study yields new insights regarding the use of contract design in protecting pre‐existing, nonrelationship specific assets in buyer‐supplier arrangements. Anecdotal examples illustrate the “dark side” of these arrangements where opportunistic suppliers exploit knowledge of buyers' pre‐existing resources to seek rent and appropriate value. When a supplier is likely to act harmfully, a closed‐price contract that specifies the price of the supplier's component upfront may reduce the supplier's incentives to overinvest in acquiring and exploiting knowledge of the buyer's pre‐existing resources. As such, when a buyer's pre‐existing resources are highly valuable, and thus more vulnerable to use by the supplier outside of the arrangement, a non‐renegotiable closed‐price contract is more efficient. Additionally, limited disclosure policies and informal agreements based on repeated interactions complement indirect governance via price contracts. Copyright © 2015 John Wiley & Sons, Ltd.  相似文献

A framework of E-SCM multi-agent systems in the fashion industry   总被引:3,自引:2,他引:1  
The fashion industry's supply chain is full of uncertainty and unpredictability. Thus, building an intelligent system to effectively capture the requirements of customers and help manage the supply chain is very important. Typical quick response (QR) systems have been broadly used in the fashion industry to serve as a way of maintaining an efficient supply chain management (SCM). The original functions of a QR system cannot, however, completely overcome the challenge of quickly satisfying the requirements of customers with effective customer relationship and quality of service. In this paper, we have integrated the typical management information system (MIS) development procedure with that of an e-fashion SCM multi-agent system. Some related research and reports from different countries have been thoroughly surveyed in order to find possible IT and non-IT methods for use in the SCM of fashion retailers. This paper thus provides an electronic fashion SCM system by adopting the techniques of the Semantic Web and multiple agents. The proposed system can integrate different information technologies to make its behavior more intelligent and to catch more useful information from customers. Its implementation also considers some practical issues in the fashion retailing SCM.  相似文献

By extending an underdeveloped idea of Lachmann, I show that the Austrian theory of the market process à la Kirzner is unable to explain the diversity of market processes because it neglects the imperfect inter-market mobility of factors of production. I show that by taking into account the imperfect mobility of capital equipment and the associated reshuffling costs, it is possible to formulate a set of empirically testable implications about the unfolding of the market process. Furthermore, I show that reshuffling costs shape the context in which the learning process takes place and that the epistemic assumption of structural opacity on which the Austrian theory of the market process relies is not incompatible with the epistemics assumption of structural transparency of neoclassical economics. These epistemic assumptions can be seen as the two poles of a “knowledge spectrum”, from potential omniscience to sheer ignorance.  相似文献

We study a widely used ordering process (“Early Bird Discounts”) whereby a profit-maximizing manufacturer permits his dealers to place advance orders at a discount before they set retail prices. We show that such discounts may be used to shift just enough channel profits to dealers to enable them to cover their fixed costs and stay in business. If the manufacturer instead simply cut his wholesale price in order to generate gross margins for his dealers, these margins would soon dissipate as price competition among dealers selling the same product forced retail prices back down to the per-unit cost. We show that when dealer fixed costs are low, the manufacturer offers an Early Bird Discount to his multiple dealers that induces all but two of them to exit; when fixed costs are high, the manufacturer offers no preorder discount (i.e. switches to linear pricing) and induces all but one dealer to exit. Although uniform slotting allowances could also be used to reward dealers, a sales-based alternative like an Early Bird Discount sometimes has a key advantage when the manufacturer has dealers in cities of different sizes. If the same Early Bird Discount is offered, dealers in markets with more consumers, who typically have larger fixed costs, will preorder larger amounts and will automatically receive higher gross margins. To duplicate such payments with slotting allowances, non-uniform allowances would have to be offered to firms in different markets, which is divisive and possibly illegal.  相似文献
