This brief introduction celebrates the 20th Anniversary of the Journal, Defence and Peace Economics. Suggesting elements of an agenda for the future of this branch of economics, I raise several topics that are new and that seem to indicate that the field will expand and shift focus substantially in future years. 相似文献

Abstract The article evaluates the security challenges that are likely to occur along international borders in East Africa with the advent of the East African Community Common Market in July 2010. In an attempt to illustrate the porosity of borders and the likelihood that criminals could take advantage of the situation, the author describes the ease with which transnational crime could thrive (in the absence of efficient border security measures) under the guise of informal cross-border trade that derives its basis largely from the customs and historical linkages in the region. Border towns in the region are considered zones of risk but also opportunities for quick money-making ventures and deals that tend to attract a variety of criminals. While the danger is not alarmingly high, there is a likelihood that with the opening up of the East African Community to the free movement of goods and people, criminals will exploit this freedom to commit crimes such as human trafficking, drug smuggling and moving terrorists and contraband goods unless mechanisms are put in place to curtail these activities. Should this not happen, the mission of the East African Community could be jeopardised. 相似文献

This article assesses the prospects for a strategy of incrementalism to lead to achievement of the core bargain of the Treaty on the Non-Proliferation of Nuclear Weapons: non-nuclear weapon states' nuclear nonproliferation in exchange for nuclear weapon states' nuclear disarmament to the point of “global zero.” Game theory, prospect theory, and liberal international theory are used to evaluate the potential of a strategy of incrementalism. While separately each has insights to offer, it is when all three theoretical approaches are used in tandem that meaningful explanatory gains emerge. The article concludes that incrementalism probably cannot lead to complete nonproliferation and global nuclear zero. Instead, signal events (as described by prospect theory) are needed to “punctuate” incremental processes in negotiations (best explained by liberal international theory) in order to move past hindrances such as international structural constraints (exemplified by game theory) and the conservative risk-taking propensities of state elites (described by prospect theory). 相似文献

This article analyzes the public side of the NH90 network consisting of four participating countries (Germany, France, Italy, and the Netherlands) and their industrial partners. Comparable to observations in earlier international projects in the defense sector, the development and production of the NH90 defense helicopter did not match original plans and costs estimates. On the basis of four mechanisms that were intended to facilitate the cooperation between the partnering countries (the General Memorandum of Understanding; coalition formation; the role of the central agency; and the process of vertical escalation) the question is posed whether or not there was a true alignment of national interests and “logics.” The lack of standardization, as well as program delays and issues concerning the division of the work-share, lead to the emerging alignment being characterized as “quasi-alignment” at best. 相似文献

Selling to strategic and loss‐averse consumers: Stocking,procurement, and product design policies 下载免费PDF全文
Motivated by the presence of loss‐averse decision making behavior in practice, this article considers a supply chain consisting of a firm and strategic consumers who possess an S‐shaped loss‐averse utility function. In the model, consumers decide the purchase timing and the firm chooses the inventory level. We find that the loss‐averse consumers' strategic purchasing behavior is determined by their perceived gain and loss from strategic purchase delay, and the given rationing risk. Thus, the firm that is cognizant of this property tailors its inventory stocking policy based on the consumers' loss‐averse behavior such as their perceived values of gain and loss, and their sensitivity to them. We also demonstrate that the firm's equilibrium inventory stocking policy reflects both the economic logic of the traditional newsvendor inventory model, and the loss‐averse behavior of consumers. The equilibrium order quantity is significantly different from those derived from models that assume that the consumers are risk neutral and homogeneous in their valuations. We show that the firm that ignores strategic consumer's loss‐aversion behavior tends to keep an unnecessarily high inventory level that leads to excessive leftovers. Our numerical experiments further reveal that in some extreme cases the firm that ignores strategic consumer's loss‐aversion behavior generates almost 92% more leftovers than the firm that possesses consumers’ loss‐aversion information and takes it into account when making managerial decisions. To mitigate the consumer's forward‐looking behavior, we propose the adoption of the practice of agile supply chain management, which possesses the following attributes: (i) procuring inventory after observing real‐time demand information, (ii) enhanced design (which maintains the current production mix but improves the product performance to a higher level), and (iii) customized design (which maintains the current performance level but increases the variety of the current production line to meet consumers’ specific demands). We show that such a practice can induce the consumer to make early purchases by increasing their rationing risk, increasing the product value, or diversifying the product line. © 2015 Wiley Periodicals, Inc.

Revenue management is the process of actively managing inventory or capacity to maximize revenues. The active management typically occurs through managerial levers such as price, promotion, or availability. We present a novel real options approach to revenue management that is specifically suited to the car rental business. We illustrate the concept with actual car rental data. The model produces minimally acceptable prices and inventory release quantities (number of cars available for rent at a given price) as a function of remaining time and available inventory. The pricing and inventory release recommendations of the developed model confirm earlier empirical analysis that suggested current practises discount too deeply early in the booking cycle. © 2004 Wiley Periodicals, Inc.

Standard approaches to classical inventory control problems treat satisfying a predefined demand level as a constraint. In many practical contexts, however, total demand is comprised of separate demands from different markets or customers. It is not always clear that constraining a producer to satisfy all markets is an optimal approach. Since the inventory‐related cost of an item depends on total demand volume, no clear method exists for determining a market's profitability a priori, based simply on per unit revenue and cost. Moreover, capacity constraints often limit a producer's ability to meet all demands. This paper presents models to address economic ordering decisions when a producer can choose whether to satisfy multiple markets. These models result in a set of nonlinear binary integer programming problems that, in the uncapacitated case, lend themselves to efficient solution due to their special structure. The capacitated versions can be cast as nonlinear knapsack problems, for which we propose a heuristic solution approach that is asymptotically optimal in the number of markets. The models generalize the classical EOQ and EPQ problems and lead to interesting optimization problems with intuitively appealing solution properties and interesting implications for inventory and pricing management. © 2003 Wiley Periodicals, Inc.
