Service quality,scale economies and ownership: an econometric analysis of water supply costs

Issues related to service quality are crucial for water utility management and regulation. Omitting these aspects, especially when they are treated as exogenous, can lead to large biases in estimating cost functions as well as to misleading information concerning technology. In this article, we integrate the output multi-dimension in the cost function, considering delivered water volume and service quality as being endogenous. Network-related scale measures and private versus public ownership are investigated with the objective of evaluating how endogenous quality may affect their impact on costs. A translog cost model is estimated from a dataset of US water utilities. It is shown that including the quality level of the delivered services has a significant impact on scale economies and ownership effects. Significant economies of scope confirm the existence of trade-offs between water production and service quality.     

THE REVOLUTION WITHIN: ICT AND THE SHIFTING KNOWLEDGE BASE OF THE WORLD'S LARGEST COMPANIES

This empirical article analyses the importance of information and communications technologies (ICT) in the technological diversification trend among the world's largest manufacturing firms during the 1980s and 1990s. The objective of the research is twofold: first, to emphasise the emerging differences among technologies when companies from different industries patent outside their traditional technological capabilities; secondly, to investigate whether the tendency among large companies from all industries to patent in ICT is distinctive when compared with the tendency to patent in other technologies. We find that technological diversification in large companies has clearly occurred in ICTs. Non-ICT specialist industries increasingly develop, rather than just utilise, the cluster of ICT-related technologies. We conclude that the development of corporate capabilities in the key technologies of the emerging ICT paradigm is more widespread than previously emphasised in the literature. One implication of this observation is that technological diversification and the information revolution may be related phenomena.     

To challenge the world view or to flow with it? Teaching sustainable development in business schools

This paper explores the fundamental question of what ‘responsibility’ means to different sets of world views adopted implicitly by business students. The exploration adopts the stakeholder theory and three subsets of the Friedman mentality to explain how individuals may value sustainability initiatives. Subsequently, it explores whether it is better to flow with the dominant economic‐driven world view as prescribed by the business school or to challenge it in order to cultivate business students with sustainability‐driven values. The conclusion highlights implications for business and management education, as well as the role of entrepreneurship to promote sustainability values.     

Product quality selection: Contractual agreements and supplier competition in an assemble-to-order environment

We consider a multi-supplier, single-manufacturer supply chain where each supplier sells a different component at varying quality levels. The manufacturer has to decide on which quality level to choose for each component, trading-off the total cost and total quality. Each supplier decides on a price per unit quality level for its component. We characterize the strategic interaction among the suppliers and analyze the inefficiencies. We find that the inefficiencies due to such quality competition can be quite significant. We then propose and analyze several mechanisms, such as quality-price schedules and revenue sharing, that restore efficiency.     

Employee service abandonment in offshore operations: A case study of a US multinational in India

Indian Business Process Outsourcing (BPO) exports industry has witnessed an exponential growth over the last few years. This has been accompanied by a shortage of talented skilled workers to serve the BPO sector. Attracting and retaining talented employees has become the chief challenge of HR departments in the BPO industry. This study examines the demographic antecedents of job abandonment among call centre employees in India using a large firm level data. The theoretical and practical implications of the findings are discussed.     

Productivity-Wage Gaps Among Age Groups: Does the ICT Environment Matter?

This paper disentangles the age-productivity-wage nexus by estimating productivity and wage equations with longitudinal employer-employee panel data for Belgium. Results indicate that workers above 49 years are significantly less productive than their younger colleagues. Moreover, while relative productivities across age groups are not found to differ significantly between ICT and non ICT firms, the upward sloping age-wage profile appears to be somewhat steeper in ICT firms. Yet, whatever the ICT environment, findings show that young workers are paid below and older workers above their marginal productivity. This pattern is in line with the deferred payment model developed by Lazear (J Polit Econ 87:1261–1284, 1979).     

Cultural values in Hong Kong's print advertising, 1946–96

This paper examines a content analysis of 580 of Hong Kong's print advertisements for the period from 1946 to 1996, which was conducted using Cheng and Schweitzer's (1996) framework of cultural values. Product categories were more determinant than the time variable in accounting for changes in cultural values. The cultural values present in advertising over time were fairly consistent and the study did not support a rapid shift from utilitarian values to symbolic values over the 50 years in question.     

EXPERIMENTAL EVIDENCE ON ENGLISH AUCTIONS: ORAL OUTCRY VERSUS CLOCK

This paper tests experimentally, in a common value setting, the equivalence between the Japanese English auction (or clock auction) and an oral outcry auction where bidders are allowed to call their own bids. We find that (i) bidding behaviour is different in each type of auction, but also that (ii) this difference in bidding behaviour does not affect significantly the auction prices. This lends some support to the equivalence between these two types of auction. The winner's curse is present: overbidding led to higher than expected prices (under Nash bidding strategies) in both types of auction. Although interesting and encouraging, the results clearly indicate that further research is necessary, particularly with a modified experimental design.     

Time-varying linkages between tourism receipts and economic growth in South Africa

The causal link between tourism receipts and GDP has recently become a major focus in the tourism economics literature. Results obtained in recent studies about the causal link appear to be sensitive with respect to the countries analysed, sample period and methodology employed. Considering the sensitivity of the causal link, we use rolling window and time-varying coefficient estimation methods to analyse the parameter stability and Granger causality based on a vector error correction model (VECM). When applied to South Africa for the period 1960–2011, the findings are as follows: results from the full-sample VECM indicate that there is no Granger causality between tourism receipts and GDP, while the findings from the time-varying coefficients model based on the state-space representation show that tourism receipts have positive-predictive content for GDP for the entire period, with the exception of the period between 1985 and 1990. Full-sample time-varying causality tests show bidirectional strong causality between tourism receipts and GDP.
