Unlimited shelf space in Internet supply chains: Treasure trove or wasteland?

Internet retailing offers merchants limitless shelf space. This has led experts to highlight the existence of a “long tail” of offerings on the web and assert that the future of online business is “selling less of more.” However, it is difficult for Internet retailers of physical goods to sell a large scope of products without having to handle potentially large amounts of product returns from customers. This is due to the fact that customers can and do get overwhelmed by excessive product variety and often make erroneous purchasing decisions. We shed light on this issue through an assessment of theoretical predictions based on data from sales and returns of almost 7000 products in a particular product category. While retailers can benefit from expanding the scope of their inventories to generate Internet sales, the success of this strategy will depend on the control of unjustified product returns by consumers and the management of recurrent execution errors and product fit failures in transactions with customers. Furthermore, from our results, the gains that this strategy will bring to retailers will be bound by the amount of time products have been available on the Internet retailer's site, as well as by other attributes such as product price and size.     

Breastfeeding versus infant formula: the Kenyan case

An Infant Feeding Practices Study (IFPS) in 1982 in Kenya, which included a cross-sectional survey of a weighted sample of 980 low and middle income Nairobi mothers who had given birth in the previous 18 months, found that most women breastfeed their infants for long periods, but many introduce alternate feeding, especially infant formula, in the 1st 4 months (86 and 50% of the infants were breastfed at 6 and 15 months respectively, but 50% of the 2 month-olds and 63% of the 4 month-olds were receiving substitutes, mostly formula). This is done largely out of the belief that infant formula is an additional health benefit. A workshop to discuss the findings of the IFPS and other available data, and to make policy recommendations urged the adoption of a policy of protection, support and promotion of breastfeeding. Since breastfeeding is already widely prevalent in Kenya, protection of breastfeeding should receive the 1st priority in policy related to infant feeding. Attention should be directed at at least 2 influences which help undermine breastfeeding: widespread availability and promotion of breast milk substitutes. Support for breastfeeding is viewed as the 2nd policy priority. Situations where support can play a helpful role are, women's paid employment outside the home, hospital practices, maternal morbidity, and difficulties in breastfeeding. Since promotion is the least cost effective of the 3 options, and most Kenyan women are already motivated to breastfeed, this should be the last priority. Promotion includes reeduction of mothers to make them better aware of the benefits of breastfeeding. The workshop recommended the dissemination of appropriate information, consisting of standarized messages based on clearcut guidelines, using mass media techniques.     

A cost-benefit analysis of landmine clearance in Mozambique

After reviewing the nature and extent of the landmine problem in Mozambique, this article applies cost-benefit analysis to landmine clearance in that country. The main benefits of clearance are saved lives, injuries and medical costs and the agricultural output that is not lost if landmines are cleared. A very large negative net present value was estimated, a result explicable by the high costs of clearance, the relatively small number of people killed or injured by landmines and the low value of agricultural productivity per hectare. The article concludes with a discussion of the role of the economist in analysing such issues and suggests some alternative areas in which financial resources would provide a greater positive impact on the welfare of Mozambicans.     

CONSUMER DIRECT FULFILLMENT PERFORMANCE IN INTERNET RETAILING: EMERGENCY TRANSSHIPMENTS AND DEMAND DISPERSION

The collaborative fulfillment of consumer orders by Internet retailers and wholesalers has proven important in the realization of sustainable levels of online profitability. Concentrating on consumer direct fulfillment (or drop shipping), an empirical simulation model evaluates avenues for improving logistical performance. The empirical simulation model centers on the online music CD retailing industry. It evaluates the effects of emergency transshipments and demand dispersion on inventory and product‐release performance, as well as on transportation costs, in consumer direct fulfillment operations. Results show that emergency transshipments improve inventory and product‐release performance in these operations. Furthermore, the inventory‐performance improvements are maximized when inventory facilities fulfill demand that is uniformly balanced across markets primarily assigned to each facility. Finally, gains in inventory and release performance obtained from emergency transshipments outweigh additional transportation costs incurred from a greater reliance on emergency transshipments for consumer direct fulfillment.     

MUST GOVERNMENT GO FISHING?

The depletion of fish stocks around the UK presents serious problems for the UK, and in particular the Scottish, fishing industry. This is a classic 'tragedy of the commons', repeatedly occurring in fisheries, where open access to a limited resource leads to serious depletion and may ultimately wipe out that resource. A recent report by the Royal Society of Edinburgh endorses the scientific basis for drastic cuts in fishing quotas under the Common Fisheries Policy to conserve stocks, and the necessary regulation and restriction of fishing effort in the UK. But it further recommends government-led initiatives to reorganise and finance the industry. Fishing in the UK is a successful entrepreneurial business and no such intervention by government is required. Government must concentrate on devising methods of regulation which, through the extension of tradable property rights in fishing, would encourage the best economic return from this important public resource.     

Politics,power, and tourism in Thailand

This paper examines the political system in Thailand with particular attention given to the location of the power in the system and its effect on the tourist industry. Noted also is the environment within which the system must operate. It is shown that while power lies with the political leaders and the bureaucracy, they are limited by the faction-ridden competitive system with the need to maintain support and offer material rewards. This has left the industry with considerable freedom to exert its power and develop. There is little opposition to development but defects in the system need to be rectified or the power balance could move, to the detriment of the industry.     

Employee Involvement And Pay At Us And Canadian Auto Suppliers

We use survey data and field research to investigate the effects of employee involvement practices on outcomes for blue-collar workers in the auto-supply industry. We find these practices raise wages by 3–5%. The causal mechanism linking involvement and wages appears to be most consistent with efficiency-wage theories, and least consistent with compensating differences. We find no evidence that employee involvement affects plants' survival or employment growth.     

Accounting for Environmental Influences in Stochastic Frontier Models: With Application to International Airlines

The principal aim of this paper is to measure the efficiency of international airlines. We obtain measures of technical efficiency from stochastic frontier production functions which have been adjusted to account for environmental influences such as network conditions, geographical factors, etc. We observe that two alternative approaches to this problem have been proposed in the efficiency measurement literature. One assumes that the environmental factors influence the shape of the technology while the other assumes that they directly influence the degree of technical inefficiency. In this paper we compare the results obtained when using these two approaches. The two sets of results provide similar rankings of airlines but suggest differing degrees of technical inefficiency. Both sets of results also suggest that Asian/Oceanic airlines are technically more efficient than European and North American airlines but that the differences are essentially due to more favourable environmental conditions. Nevertheless, it is among Asian companies that the major improvements in managerial efficiency (technical efficiency with environmental factors netted out) took place over the sample period (1977–1990).     

Strategic network formation through peering and service agreements

We introduce a game theoretic model of network formation in an effort to understand the complex system of business relationships between various Internet entities (e.g., Autonomous Systems, enterprise networks, residential customers). In our model we are given a network topology of nodes and links where the nodes act as the players of the game, and links represent potential contracts. Nodes wish to satisfy their demands, which earn potential revenues, but may have to pay their neighbors for links incident to them. We incorporate some of the qualities of Internet business relationships, including customer–provider and peering contracts. We show that every Nash equilibrium can be represented by a circulation flow of utility with certain constraints. This allows us to prove bounds on the prices of anarchy and stability. We also focus on the quality of equilibria achievable through centralized incentives.     

The Paradoxical Behavioral Effects of a Directional Goal on Investors' Risk Perceptions and Valuation Judgments

Market participants who evaluate risk often have a preference or goal for positive company performance. The authors test how such a directional goal affects risk perceptions and the relation between risk perceptions and assessments of value in an investment context. Compared with investors without directional goals—who, consistent with prior behavioral research, focus on negative aspects of risk—the authors find that those with directional goals assess risk as being more symmetric (i.e., they are less focused on downside risk). However, investors with directional goals are also less likely to consider risk when assessing value. Taken together, these results suggest that a directional goal reduces one behavioral effect identified in prior literature (the tendency to focus on downside risk), but creates another behavioral effect (ignoring risk in assessing value). The authors discuss implications for standard setters and regulators seeking to communicate risk information to market participants.
