摘要:In this paper, we revisit and clarify the celebrated machine maintenance and sale age model of Kamien and Schwartz (KS) involving a machine subject to failure. KS formulate and solve the problem as a deterministic optimal control problem with the probability of the machine failure as the state variable. Thus, they obtain deterministic optimal maintenance and sale date. We study two underlying stochastic models with known and random machine modes, and clarify the relationship between the result...

摘要:Performance-based contracting is reshaping service support supply chains in capital-intensive industries such as aerospace and defense. Known as ''power by the hour'' in the private sector and as ''performance-based logistics'' (PBL) in defense contracting, it aims to replace traditionally used fixed-price and cost-plus contracts to improve product availability and reduce the cost of ownership by tying a supplier's compensation to the output value of the product generated by the customer (buye...

摘要:This paper develops empirical proxy measures of information technology (IT) risk and incorporates them into the usual empirical models for analyzing IT returns: production function and market value specifications. The results suggest that IT capital investments make a substantially larger contribution to overall firm risk than non-IT capital investments. Further, firms with higher IT risk have a higher marginal product of IT relative to firms with low IT risk. In the market value specification...

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:Selection procedures are used in a variety of applications to select the best of a finite set of alternatives. ''Best'' is defined with respect to the largest mean, but the mean is inferred with statistical sampling, as in simulation optimization. There are a wide variety of procedures, which begs the question of which selection procedure to select. The main contribution of this paper is to identify, through extensive experimentation, the most effective selection procedures when samples are in...

摘要:In this paper, we examine the pattern of correlation among consumer price sensitivities for customer purchase incidence decisions across complementary product categories. We use a hierarchical Bayesian multivariate probit model to uncover this pattern. We estimated this model using purchase incidence data for six categories involving three pairs of complementary products. Our results show a new and interesting pattern of correlation among price parameters of complementary products. For example...

摘要:In a stylized model of biopharmaceutical. contract manufacturing, this paper shows how the potential for renegotiation influences the optimal structure of supply contracts, investments in innovation and capacity; the way scarce capacity is allocated, and firms' resulting profits. Two buyers contract for capacity with a common manufacturer. Then, the buyers invest in innovation (product development and marketing) and the manufacturer builds capacity. Finally, the firms may renegotiate to allow ...

摘要:Because of the heterogeneous nature of different data sources, data integration is often one of the most challenging tasks in managing modern information systems. While the existing literature has focused on problems such as schema integration and entity identification, it has largely overlooked a basic question: When an attribute value for a real-world entity is recorded differently in different databases, how should the ''best'' value be chosen from the set of possible values? This paper pro...

摘要:A manufacturer writes supply contracts with N buyers. Then, the buyers invest in innovation, and the manufacturer builds capacity. Finally, demand is realized, and the firms renegotiate the supply contracts to achieve an efficient allocation of capacity among the buyers. The court remedy for breach of contract (specific performance versus expectation damages) affects how the firms share the gain from renegotiation, and hence how the firms make investments ex ante. The firms may also engage in ...
