摘要：The application of Internet-based virtual stock markets (VSMs) is an additional approach that can be used to predict short- and medium-term market developments. The basic concept involves bringing a group of participants together via the Internet and allowing them to trade shares of virtual stocks. These stocks represent a bet on the outcome of future market situations, and their value depends on the realization of these market situations. In this process, a VSM elicits and aggregates the asse...

摘要：This paper deals with a single-echelon inventory system consisting of a number of parallel local warehouses facing compound Poisson demand. There are standard holding and backorder costs as well as ordering costs at all warehouses. Normally, the warehouses replenish from an outside supplier. However, lateral transshipments between the warehouses are also possible. Such transshipments take no time but incur additional costs. When a demand,occurs at a warehouse, the question is whether the whole...

摘要：We explore opportunities for targeted pricing for a retailer that only tracks weekly store-level aggregate sales and marketing-mix information. We show that it is possible, using these data, to recover essential features of the underlying distribution of consumer willingness to pay. Knowledge of this distribution may enable the retailer to generate additional profits from targeting by using choice information at the checkout counter. In estimating demand we incorporate a supply-side model of t...

摘要：Many clinics that offer in vitro fertilization (IVF) have begun to market the following options to couples: (1) an a la carte program where the couple pays $7,500 per attempt regardless of the outcome; or (2) a money-back-guarantee program where the couple pays a $15,000 fee that covers up to three attempts, however, if after three cycles there is no live-birth delivery, then the full $15,000 is refunded. We assess the a la carte versus the money-back-guarantee programs, and find the surprisin...

摘要：his paper surveys the underlying theory and practice in the use of options in support of emerging business-to-business (B2B) markets. Such options, on both capacity and output, play an important role in integrating long- and short-term contracting between multiple buyers and sellers in such markets. This trend is especially important in capital-intensive industries, where improvements in fine tuning the coordination of supply and demand carry large economic benefits. Typically, such options ar...

摘要：Combinatorial auctions have two features that greatly affect their design: computational complexity of winner determination and opportunities for cooperation among competitors. Dealing with these forces trade-offs between desirable auction properties such as allocative efficiency, revenue maximization, low transaction costs, fairness, failure freeness, and scalability. Computational complexity can be dealt with algorithmically by relegating the computational burden to bidders, by maintaining f...

摘要：Opportunism is a central construct in exchange theory. Economists contend that despite the firm's best efforts to erect governance structures that reduce opportunism and preserve outcomes, there is always some opportunism that remains once the transaction is in,place. Despite this, there are few studies that systematically investigate the safeguarding efficacy of relationship attributes in the presence of such ex post opportunism. In this research, we develop a theoretical framework and provid...

摘要：We study a generic, minimization problem with separable nonconvex piecewise linear costs, showing that the linear programming (LP) relaxation of three textbook mixed-integer programming formulations each approximates the cost function by its lower convex envelope. We also show a relationship between this result and classical Lagrangian duality theory.

摘要：In this paper, we develop an analytical model of outside. directors' signaling role-a role that is especially important for entrepreneurial firms. We formally demonstrate that in the face of a market failure in which stakeholders refuse to align themselves with new firms, high-quality new ventures may be able to credibly signal their type by appointing reputable directors to their boards. However, this option is not universally feasible. Both directors' reputations and the quality of their inf...

摘要：The Pratt-Arrow measure of local risk aversion is generalized for the n-dimensional state-preference model of choice under uncertainty in which the decision maker may have inseparable subjective probabilities and utilities, unobservable stochastic prior wealth, and/or smooth nonexpected-utility preferences. Local risk aversion is measured by the matrix of derivatives of the decision maker's risk-neutral probabilities, without reference to true subjective probabilities or riskless wealth positi...
