The composition of interest: The judaic prohibition

An interest charge is made up of an award for waiting known as the real rate of interest, a premium for risk and compensation for transaction costs. Where inflation exists the lender seeks further compensation. In order to understand the composition and evolution of different versions of the usury prohibition it is necessary to ask which components of an interest charge are prohibited by each version. The Judaic prohibition has two aspects which are of particular interest to business historians and students of usury. First, the general rule is that a reward for waiting is prohibited. This focuses on the time-based part of interest charge. Second, interest is prohibited because it amounts to placing a stumbling block before the blind. This focuses on the typical gullibility of the borrower confronted by a more expert, better funded lender. Economics confirms and enriches our understanding of these important aspects of the prohibition. They achieve this by increasing our understanding of two facts: first, that the borrower is a gullible individual subject to irrational and inconsistent behaviour; and, second, that this behaviour relates to the waiting aspect of interest which is proscribed in the prohibition. How far these insights apply to other civilisations' prohibition, particularly those which derive from the Judaic prohibition, merits further study; so also do the ethical lessons of the Mosaic rules for a globalised society based on capitalism.     

Searching for the sunk cost fallacy

We seek to isolate in the laboratory factors that encourage and discourage the sunk cost fallacy. Subjects play a computer game in which they decide whether to keep digging for treasure on an island or to sink a cost (which will turn out to be either high or low) to move to another island. The research hypothesis is that subjects will stay longer on islands that were more costly to find. Eleven treatment variables are considered, e.g. alternative visual displays, whether the treasure value of an island is shown on arrival or discovered by trial and error, and alternative parameters for sunk costs. The data reveal a surprisingly small sunk cost effect that is generally insensitive to the proposed psychological drivers.

National culture and R&D and marketing integration mechanisms in new product development: A cross-cultural study between Singapore and New Zealand

The integration of R&D and marketing in new product development (NPD) is an important contributor to NPD performance. Of the mechanisms developed to aid functional integration, many have been developed in western cultural environments and may not have applicability in other national cultural settings. Using a sample of NPD workgroup personnel in New Zealand (NZ), the western cultural environment, and Singapore, quantitative and qualitative data have been used to measure national culture and determine the applicability of different organization integration mechanisms. Results show key differences between the two samples, indicating a link between formalization, centralization, role flexibility and interfunctional climate mechanisms with the Hofstede dimensions of Power Distance, Masculinity and Uncertainty Avoidance of national culture. Managerial implications are that national cultural values and settings of the respondents are important when determining best integration mechanisms.     

On the prediction of financial distress in developed and emerging markets: Does the choice of accounting and market information matter? A comparison of UK and Indian Firms

We examine differences in price delay for a sample of real estate investment trust (REIT) and non-REIT matched pairs. Results suggest an economically and statistically higher level of price delay for REIT securities, which implies heightened frictions that increase the time needed for new information to be impounded into the prices of REIT shares. The primary drivers for the observed delay differential include differences in idiosyncratic volatility, market risk, and the number of days traded. Within-REIT determinants of delay confirm findings for the pooled sample of matched pairs. Importantly, we infer find that REIT investors are not compensated for restricted information flow, as excess returns are unrelated to the price delay.     

The future of health futures : Another perspective

A good ‘market’ for health futures and easy access to relevant information are among the reasons that health futures is currently centred in the wealthy nations. Interest in health futures is growing in the less developed countries, however, in part because of efforts by WHO and its regional office. Many benefits can be expected if the field becomes more international, including an influx of fresh ideas about health futures study designs and about innovative approaches to health care. A shift to a more global orientation is also imperative simply because health futures deals with the well-being of human beings, and most human beings live in the less developed countries of the world.     

National 21st century studies : Model for an effective approach

National 21st century studies are being carried out in most parts of the world today and are gaining considerable attention. These studies share certain key characteristics that set them apart from many future studies, yet they also exhibit quite a variety of differences, including ones in sectoral coverage, methodology, and purpose. The significance of these variations is discussed in this article, which also outlines, on the basis of the studies to date, a model for an effective national 21st century study.     

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.     

An International Comparison and Analysis of Lotteries and the Distribution of Lottery Expenditures

Lotteries are found in nearly half of the world's countries, with annual worldwide lottery ticket sales topping $115 billion. Despite the global presence of lottery games, there has been little research conducted on any international aspect of lotteries. This paper presents the first-ever examination and comparison of lottery games from around the world. Differences in both absolute and relative lottery expenditures are presented. Estimates for the income elasticity of demand for lottery tickets provide evidence on the distributional burden of lottery expenditures. These estimates consider each country by continental location and country income level. Further analysis reveals that lower income countries could adopt Lotto games in order to increase revenues. Recognizing that the distributional impact of lottery games is one of the greatest concerns surrounding lotteries, it is shown that the introduction of Lotto games does not significantly affect the distributional burden of lottery ticket expenditures. Given the international scope of lotteries and the availability of international lottery game data, the paper concludes by discussing future research on international lottery games.
