摘要：Studying the U.S. personal computer industry from its inception in 1974 through 1994, we address the following questions. What product technology strategies increase the survival chances of entrants into new, technologically dynamic industries? Does the effectiveness of these strategies differ by pre-entry experience? Does the effectiveness of these strategies differ by when firms enter a new industry? Consistent with the published literature, we find that diversifying entrants have an initial...

摘要：Empirical evidence on the distributional characteristics of common stock returns indicates: (1) A power-law tail index close to three describes the behavior of the positive tail of the survivor function of returns (pr(r > x) similar to x(-alpha)), a reflection of fat tails; (2) general linear and nonlinear dependencies exist in the time series of returns; (3) the time-series return process is characterized by short-run dependence (short memory) in both returns as well as their volatility, the ...

摘要：We study competitive interactions between Intel and Microsoft, two producers of complementary products. In a system of complements, like the PC, the value of the final product depends on how well the different components work together. This, in turn, depends on the firms' investment in complementary R&D. We ask whether Intel and Microsoft will want to cooperate and make the final product as valuable as possible. Contrary to the popular view that two tight complements will generally have well a...

摘要：This paper presents a field study into the effects of statistical information concerning risks on willingness to take insurance, with special attention being paid to the usefulness of these effects for the clients (the insured). Unlike many academic studies, we were able to use in-depth individual interviews of a large representative sample from the general public (N = 476). The statistical information that had the most interesting effects, individual own past-cost information, unfortunately e...

摘要：We develop a model of consumer learning and choice behavior in response to uncertain service in the marketplace. Learning could be asymmetric, that is, consumers may associate different weights with positive and negative experiences. Under this consumer model, we characterize the steady-state distribution of demand for retailers given that each retailer holds a constant in-stock service level. We then consider a noncooperative game in steady state between two retailers competing on the basis o...

摘要：This paper studies a procurement problem with one buyer and multiple potential suppliers who hold private information about their own production costs. Both the purchase quantity and the price need to be determined. An optimal procurement strategy for the buyer requires the buyer to first design a supply contract that specifies a payment for each possible purchase quantity and then invites the suppliers to bid for this contract. The auction can be conducted in many formats such as the English ...

摘要：This paper studies how judicious resource allocation in networks mitigates risk. Theory is presented for general utility functions and mean-variance formulations and is illustrated with networks featuring resource diversification, flexibility (e.g., inventory substitution), and sharing (commonality). In contrast to single-resource settings, risk-averse newsvendors may invest more in networks than risk-neutral newsvendors: some resources and even total spending may exceed risk-neutral levels. W...

摘要：In recent years, understanding the structure and function of complex networks has become the foundation for explaining many different real-world complex biological, technological, and informal social phenomena. Techniques from statistical physics have been successfully applied to the analysis of these networks, and have uncovered surprising statistical structural properties that have also been shown to have a major effect on their functionality dynamics, robustness, and fragility. This paper e...

摘要：Both noncooperative and cooperative game theory have been applied to business strategy. We propose a hybrid noncooperative-cooperative game model, which we call a biform game. This is designed to formalize the notion of business strategy as making moves to try to shape the competitive environment in a favorable way. (The noncooperative component of a biform game models the strategic moves. The cooperative component models the resulting competitive environment.) We give biform models of various...

摘要：Horizontal scope-the set of products and services offered-is an important dimension of firm strategy and a potentially significant source of competitive advantage. On one hand, the ability to build close buyer-supplier relationships over multiple transactions can give an advantage to broad firms that offer buyers one-stop shopping. On the other hand, the existence of organizational tradeoffs can give an advantage to firms that specialize in a narrower range of products or services. We develop ...
