Dynamic Efficiency with Learning by Doing

This article focuses on the measurement of economic efficiency of firms in an industry in a dynamic framework, where R&D investments and learning experience play critical roles. Dynamic aspects of cost and production efficiency and the impact of capital through learning by doing are developed here in semiparametric forms. The production and cost frontiers estimated here for the US computer industry over the period 1987–98 are robust in the sense that no specific functional form need be assumed. The empirical estimates measure the pattern of level and growth efficiency in the computer industry, which has undergone rapid changes in recent years.     

Integrated rural development—helping people help themselves

Sanjit Roy argues that the quest for social justice and the equal distribution of wealth is implicit in any integrated rural development (IRD) project. He claims that up until now, these issues have been rarely linked in India, which has lead to failure. In setting up any IRD programme, the questions of which people and what form of participation is necessary, must be addressed with care. The author argues that those who live below the poverty line should be the main target of such schemes, and these communities must be reached without intermediaries. There is a desperate need in India for face-to-face encounters between the professional and the beneficiary: between geologist and farmer, nurse and pregnant woman, teacher and truant. Such an approach is more likely to bring about a degree of participation beyond that reached so far. Sanjit Roy explains how basically it is a matter of trust; the poor must be trusted to think positively about their own development and the social barriers which have prevented this must be broken down.     

A cross-country study of service productivity

This study empirically examines service productivity and complements prior studies by framing service productivity as consisting of a number of key constituents. Adopting a bottom-up approach we present an integrative model proposing that resource commitment is the core from which employee readiness and customer readiness flow. These inform service productivity, which, in turn, informs job security. Our empirical examination reveals that service productivity has an impact on perceptions of job security, while resource commitment has the greatest impact on both employee readiness and customer readiness. In developing our integrative model we provide a framework that other researchers can apply, particularly where the service is highly intangible or in the public sector where service providers are being increasingly challenged to demonstrate value for money.     

A fractile programming approach with extreme sample estimates of parameters

Abstract This paper investigates the implications of extreme value estimates of net prices in the objective function of a linear programming problem. Analytically, our approach suggests interesting points of comparison between different measures of sensitivity of a linear programming problem, when a specified fractile of the distribution of profits is optimized.

The Co-Diffusion of Complementary Innovations: Supermarket Scanners and UPC Symbols

Co-diffusion is the positive interaction between the demands for complementary innovations that have separate adoption tracks. This interaction is of growing importance to business strategy because a firm can facilitate the diffusion of an innovation by supporting and participating in the development and commercialization of related complementary technologies. This phenomenon is of special importance where connectivity among products is central to end-user value. Louis P. Bucklin and Sanjit Sengupta report results of their empirical investigation of the co-diffusion of laser scanners in supermarkets and Universal Product Code (UPC) symbols printed on the packages of stocked items. Their results show asymmetric two-way co-diffusion effects between these innovations. Co-diffusion effects are found to be stronger than innovation effects. Finally, the analysis reveals differential co-diffusion effects across major market segments.     

AN ALTERNATIVE AXIOMATIZATION OF SEN'S POVERTY MEASURE

We provide an alternative axiomatization of Sen's (1976) poverty measure. We derive the measure from the general definition of a poverty measure by using a version of Sen's rank order axiom, and a substantially weaker form of his normalization axiom. These two axioms, together with a continuity axiom, lead uniquely to the measure suggested by Sen (1976).     

Convenience and satisfaction: mediation of fairness and quality

This study investigates the role of service fairness and service quality in the relationship between service convenience types (decision, access, transaction, benefit and post-benefit) and customer satisfaction. Results show that service convenience has a significant positive impact on service fairness. Both service fairness and service quality mediate the relationship between service convenience and customer satisfaction. This study provides useful insights to both researchers and practitioners on the role of service convenience in improving service fairness, service quality and customer satisfaction. Findings of this study contribute to the literature by empirically investigating the impact of service convenience types on service fairness, service quality and customer satisfaction; and by examining the mediating role of service fairness and service quality between convenience types and customer satisfaction.
