  摘要：Acompanion paper (Campbell et al. 2005) introduces new hub arc location models and analyzes optimal solutions, with special attention to spatial pattens and relationships. This paper provides integer programming formulations and optimal solution algorithms for these problems. We describe two optimal solution approaches in detail and compare their performance, using standard hub location data sets. We present implementation details and show how algorithms can be fine tuned based on characterist...
• Hub arc location problems: Part I - Introduction and results AI翻译

  摘要：Hub networks play an important role in many transportation and telecommunications systems. This paper introduces a new model called the hub arc location model. Rather than locate discrete hub facilities, this model locates hub arcs, which have reduced unit flow costs. Four special cases of the general hub arc location model are examined in detail. We provide motivation for the new models, and present examples and optimal solutions, using data for U.S. air passenger traffic. Results are used to...
• Two-sided network effects: A theory of information product design AI翻译

  摘要：How can firms profitably give away free products? This paper provides a novel answer and articulates trade-offs in a space of information product design. We introduce a formal model of two-sided network externalities based in textbook economics-a mix of Katz and Shapiro network effects, price discrimination, and product differentiation. Externality-based complements, however, exploit a different mechanism than either tying or lock-in even as they help to explain many recent strategies such as ...
• Weak-form and semi-strong-form stock return predictability revisited AI翻译
  作者：Ferson, WE; Heuson, A; Su, T

  摘要：This paper makes indirect inference about the time variation in expected stock returns by comparing unconditional sample variances to estimates of expected conditional variances. The evidence reveals more predictability as more information is used, and there is no evidence that predictability has diminished in recent years. Semi-strong-form evidence suggests that time variation in expected returns remains economically important.
• Bundling with customer self-selection: A simple approach to bundling low-marginal-cost goods AI翻译
  作者：Hitt, LM; Chen, PY
  作者单位：University of Pennsylvania; Carnegie Mellon University
  摘要：With declining costs of distributing digital products comes renewed interest in strategies for pricing goods with low marginal costs. In this paper, we evaluate customized bundling, a pricing strategy that gives consumers the right to choose up to a quantity M of goods drawn from a larger pool of N different goods for a fixed price. We show that the complex mixed-bundle problem can be reduced to the customized-bundle problem under some commonly used assumptions. We also show that, for a monopo...
• Optimal policies for transshipping inventory in a retail network AI翻译
  作者：Wee, KE; Dada, M
  作者单位：Singapore Management University; Purdue University System; Purdue University
  摘要：Motivated by recent reports of improved customer service facilitated by the use of transshipment to pool inventory, we develop a formal model that focuses on the role of transshipment in a system of n-retailers who stock a good. In addition, some stock may be kept at a warehouse. If a retailer faces a stockout, he makes an attempt to fill backorders by using a transshipment that may come either from the warehouse or from another retailer that has excess stock. We determine that the optimal tra...
• Conspicuous consumption and sophisticated thinking AI翻译
  作者：Amaldoss, W; Jain, S
  作者单位：Duke University; University System of Maryland; University of Maryland College Park
  摘要：Consumers purchase conspicuous goods to satisfy not only material needs but also social needs such as prestige. In an attempt to meet these social needs, producers of conspicuous goods like cars, perfumes, and watches, highlight the exclusivity of their products. In this paper, we propose a monopoly model of conspicuous consumption using the rational expectations framework, and then examine how purchase decisions are affected by the desire for exclusivity and conformity. We show that snobs can...
• Using capital markets as market intelligence: Evidence from the pharmaceutical industry AI翻译
  作者：Markovitch, DG; Steckel, JH; Yeung, B
  作者单位：Hautes Etudes Commerciales (HEC) Paris; New York University
  摘要：Financial theory posits that capital markets convey through stock prices their expectation of the firm's future performance. We use concepts from principal-agent theory and prospect theory to provide a theoretical explanation for the role stock price variation plays in managerial decision making. We then empirically investigate what specific decisions managers undertake in response to stock price variation. We perform our empirical analyses in the context of the pharmaceutical industry. We fin...
