Optimal inventory and pricing policies for remanufacturable leased products

In this paper we consider a company which leases new products and also sells remanufactured versions of the new product that become available at the end of their lease periods. When the amount of end-of-lease items in stock is not sufficient to meet the demand for remanufactured products, the firm may purchase additional cores from a third-party supplier. We develop a dynamic programming formulation for determining the optimal price of remanufactured products, and optimal payment structure for the leased products. Our objective is to maximize the discounted system-wide profit over a finite horizon. The profit function consists of revenues that are obtained from remanufactured product sales and leasing, remanufacturing and manufacturing costs, inventory holding and shortage costs. We consider a consumer choice based demand model for mapping a potential customer into one of the product segments (a remanufactured product customer or a customer for a leased product with a particular lease period) for a given price/lease payment vector. We explore several properties of the discounted profit function and provide insight on the behavior of pricing and inventory policies. We also investigate the effect of key product characteristics such as deterioration in age, cost of shortage in remanufacturable product inventory, and key market characteristics such as relative willingness-to-pay for buying a remanufactured product and relative willingness-to-pay for leasing a new product on optimal pricing policies through a computational study.     

Information Measures in Perspective

Information-theoretic methodologies are increasingly being used in various disciplines. Frequently an information measure is adapted for a problem, yet the perspective of information as the unifying notion is overlooked. We set forth this perspective through presenting information-theoretic methodologies for a set of problems in probability and statistics. Our focal measures are Shannon entropy and Kullback–Leibler information. The background topics for these measures include notions of uncertainty and information, their axiomatic foundation, interpretations, properties, and generalizations. Topics with broad methodological applications include discrepancy between distributions, derivation of probability models, dependence between variables, and Bayesian analysis. More specific methodological topics include model selection, limiting distributions, optimal prior distribution and design of experiment, modeling duration variables, order statistics, data disclosure, and relative importance of predictors. Illustrations range from very basic to highly technical ones that draw attention to subtle points.     

International tourism model for developing economies

This article considers international tourism as an open system consisting of four essential components: demand, marketing, transportation, and accomodation. It examines each component and its relationship to the system. The proposed international tourism model facilitates detection of positive and negative determinants of the system so that a relevant marketing strategy can be developed. The major strategies include a mass-marketing approach for public through tourism intermediaries, and a focused strategy requiring careful analysis of the target market and its needs for unique services. More specifically, the article suggests extensive market analysis with geographic concentration on present and potential tourist generating countries. The model is intended as a comprehensive frame for policy makers and practitioners to evaluate the advantages and disadvantages of international tourism.     

American and European expatriate managers: An empirical investigation

This article compares American and European expatriate managers' backgrounds, job satisfaction, and perception of local work and cultural environment in Turkey in reference to their adaptation to the host country and their job performance. It reports that the sample managers demonstrate differences in all these dimensions. Therefore multinational companies are recommended to develop human resources policies in choosing expatriate managers most likely to adapt to work and host country environments by paying attention to managerial qualifications and local conditions. They should also train and prepare both expatriate and local managers to ensure smooth relationships between two groups. © 1993 John Wiley & Sons, Inc.     

Rent Sharing In the Multi-Fibre Arrangement: Theory and Evidence From Us Apparel Imports From Hong Kong*

Available estimates of tariff equivalents and welfare costs of MFA quotas are based on the premise of perfect competition in both product and license markets, and the assumption that exporting countries receive all the scarcity rent. We test if US apparel imports from Hong Kong conform with this competitive model by looking at whether the license-price-inclusive Hong Kong price, adjusted for tariffs and transport costs, is equal to the US price. We deal with the homogeneous product case and correct for both aggregation and quality differences. We find that US importers seem to retain a substantial portion of the quota rents.     

An assessment of Colombian managers' perceptions of international strategic alliances

This article reports the results of a survey of Colombian managers concerning their perceptions of strategic alliances with foreign firms. The survey focuses in particular on partner selection and the managerial expectations from such partnerships, as well as the potential difficulties involved in developing interfirm linkages. The survey of Colombian managers shows that international strategic alliances are considered a viable approach to building a competitive advantage, especially in domestic markets, either through acquiring Western technology or marketing know-how. However, the survey results also suggest that a number of obstacles need to be overcome. The important considerations in partner selection, competence building through strategic alliances, and dealing with potential problems in establishing interfirm partnerships are discussed. © 1995 John Wiley & Sons, Inc.     

Information measures for generalized gamma family

The objective of this paper is to integrate the generalized gamma (GG)$(\mathit{GG})$ distribution into the information theoretic literature. We study information properties of the GG$\mathit{GG}$ distribution and provide an assortment of information measures for the GG$\mathit{GG}$ family, which includes the exponential, gamma, Weibull, and generalized normal distributions as its subfamilies. The measures include entropy representations of the log-likelihood ratio, AIC, and BIC, discriminating information between GG$\mathit{GG}$ and its subfamilies, a minimum discriminating information function, power transformation information, and a maximum entropy index of fit to histogram. We provide the full parametric Bayesian inference for the discrimination information measures. We also provide Bayesian inference for the fit of GG$\mathit{GG}$ model to histogram, using a semi-parametric Bayesian procedure, referred to as the maximum entropy Dirichlet (MED). The GG$\mathit{GG}$ information measures are computed for duration of unemployment and duration of CEO tenure.
