摘要：We present evidence on components of productivity change in the public accounting industry toward the end of the 20th century. Using revenue and human resource data from 64 of the 100 largest public accounting firms in the United States for the 1995-1999 period, we analyze productivity change, technical progress, and relative efficiency change over time. The average public accounting firm experienced a productivity growth of 9.5% between 1995 and 1999. We find support for the hypothesis that t...

摘要：Managers often employ market response models as decision aids and historical information of competitors' market outcomes to aid their competitive decisions in oligopolistic settings. However, little is known about how access to a decision aid or the availability of competitors' market outcomes impact a firm's competitive decisions (e.g., prices) or market outcomes resulting from those decisions (e.g., profits), or how managers make these decisions across such informational conditions. Hence, t...

摘要：Computing the optimal portfolio policy of an investor facing capital gains tax is a challenging problem: because the tax to be paid depends on the price at which the security was purchased (the tax basis), the optimal policy is path dependent and the size of the problem grows exponentially with the number of time periods. Dammon et al. (2001, 2002, 2004), Garlappi et al. (2001), and Gallmeyer et al. (2001) address this problem by approximating the exact tax basis by the weighted average purcha...

摘要：In many business transactions, labor-management relations, international conflicts, and welfare-state reforms, bargainers hold strong entitlements that are often generated by claims that are not feasible anymore. These entitlements seem to shape negotiation behavior considerably. By using the novel setup of a bargaining with claims experiment, we provide new systematic evidence tracking the influence of entitlements and obligations through the whole bargaining process. We find strong entitleme...

摘要：One of the key problems in database marketing is the identification and profiling of households that are most likely to be interested in a particular product or service. Principal component analysis (PCA) of customer background information followed by logistic regression analysis of response behavior is commonly used by database marketers. In this paper, we propose a new approach that uses artificial neural networks (ANNs) guided by genetic algorithms (GAs) to target households. We show that t...

摘要：Inventory turnover varies widely across retailers and over time. This variation undermines the usefulness of inventory turnover in performance analysis, benchmarking, and working capital management. We develop an empirical model using financial data for 311 publicly listed retail firms for the years 1987-2000 to investigate the correlation of inventory turnover with gross margin, capital intensity and sales surprise (the ratio of actual sales to expected sales for the year). The model explains...

摘要：We analyze the allocation of priority in queues via simple bidding mechanisms. In our model, the stochastically arriving customers are privately informed about their own processing time. They make bids upon arrival at a queue whose length is unobservable. We consider two bidding schemes that differ in the definition of bids (these may reflect either total payments or payments per unit of time) and in the timing of payments (before or after service). In both schemes, a customer obtains priority...

摘要：An algorithm is developed to rapidly compute approximations for all the standard steady-state performance measures in the basic call-center queueing model M/GI/s/r + GI, which has a Poisson arrival process, independent and identically distributed (IID) service times with a general distribution, s servers, r extra waiting spaces and IID customer abandonment times with a general distribution. Empirical studies of call centers indicate that the service-time and abandon-time distributions often ar...

摘要：Flexible capacity has been shown to be very effective to hedge against forecast errors at the investment stage. In a make-to-order environment, this flexibility can also be used to hedge against variability in customer orders in the short term. For that purpose, production levels must be adjusted each period to match current demands, to give priority to the higher margin product, or to satisfy the closest customer. However, this will result in swings in production, inducing larger order variab...

摘要：In this paper, we present a new perspective on flexibility in manufacturing and service operations by exploring a type of operational flexibility that we term structural flexibility (SF). We focus on strategic-level issues of how flexibility can be created by using multipurpose resources such as cross-trained labor, flexible machines, or flexible factories. The proposed structural flexibility method uses the structure of the capability pattern to generate indices that quantify the ability of a...
