Subscription Mechanisms for Network Formation

We analyze a model of network formation where the costs of link formation are publicly known but individual benefits are not known to the social planner. The objective is to design a simple mechanism ensuring efficiency, budget balance, and equity. We propose two mechanisms towards this end; the first ensures efficiency and budget balance but not equity. The second mechanism corrects the asymmetry in payoffs through a two-stage variant of the first mechanism. Journal of Economic Literature Classification Numbers: C71, C72, D20.     

Experimental study of repeated team-games

We report an experiment in which the Intergroup Prisoner's Dilemma (IPD) game was contrasted with a structurally identical (single-group) Prisoner's Dilemma (PD). The games were played repeatedly for 40 rounds. We found that subjects were initially more likely to cooperate in the IPD game than in the PD game. However, cooperation rates decreased as the game progressed and, as a result, the differences between the two games disappeared. This pattern is consistent with the hypothesis that subjects learn the structure of the game and adapt their behavior accordingly. Computer simulations based on a simple learning model by Roth and Erev (Learning in extensive-form games: Experimental data and simple dynamic models in the intermediate term, Games and Economic Behavior 8, 164–212, 1995) support this interpretation.     

Price‐matching guarantees

Are price‐matching guarantees anticompetitive? We examine the incentives for price‐matching guarantees in markets where information about prices is costly. The conventional explanation of price matching as facilitating cartel pricing finds some theoretical support, but our model provides an additional explanation. A price‐matching guarantee may be a credible and easily understood means of communicating to uninformed consumers that a firm is low priced. The credibility of the signal is assured by the behavior of informed consumers. We contrast the testable implications of our model with those arising from two theories of price matching as anticompetitive, and show that available evidence supports the signalling theory.     

Individual Differences in the Acceptability of Unethical Information Technology Practices: The Case of Machiavellianism and Ethical Ideology

While information technologies present organizations with opportunities to become more competitive, unsettled social norms and lagging legislation guiding the use of these technologies present organizations and individuals with ethical dilemmas. This paper presents two studies investigating the relationship between intellectual property and privacy attitudes, Machiavellianism and Ethical Ideology, and working in R&D and computer literacy in the form of programming experience. In Study 1, Machiavellians believed it was more acceptable to ignore the intellectual property and privacy rights of others. Programmers and R&D workers considered violating intellectual property rights more acceptable. Programmers did not consider violating privacy rights more acceptable, but R&D workers did. Finally, there was an interaction between Machiavellianism, programming and R&D. Machiavellians who also had programming experience or worked in R&D found violations of intellectual property much more acceptable. The effect of Machiavellianism on attitudes toward violations of privacy was enhanced by working in R&D, but not by programming experience. In Study 2, idealists believed it was less acceptable to ignore the intellectual property and privacy rights of others. Relativists found it more acceptable to violate intellectual property rights, though they did not consider it more acceptable to violate privacy rights. Those with programming experience were more accepting of intellectual property rights violations, but not of privacy violations. Finally, programming experience moderated the relationship between idealism, relativism and attitudes toward these unethical information practices. Implications for diminishing unethical behavior among Machiavellians, Relativists, programmers and those in R&D are discussed.     

LEASING AND THE US 1986 TAX REFORM ACT

The US 1986 Tax Reform Act (TRA) contains several tax provisions affecting many areas of corporate finance including lease financing. One of the more important provisions is the Alternative Minimum Tax (AMT) which determines an alternative in addition to the usual tax computation, and consequently results in a new lessee-lessor tax-asymmetry. To investigate the overall impact on the net advantage of leasing (NAL) of both the AMT and the other relevant provisions of the TRA, a leasing model is developed which incorporates these tax provisions. In the context of this leasing model, the following results are derived. When the AMT provision does not apply, the Tax Reform Act (TRA) reduces substantially the net advantage of leasing (NAL) over buying. In contrast, the effect of the AMT symmetry is positive. As a result, the combined effect of the AMT and the other changes in the TRA on the NAL is negligible for property class of assets of the more common length of time (about ten years), but becomes negative for real-property type of assets.     

Top down or bottom up? Issues in the development of sub-national tourism satellite accounts

It is well known that tourism makes extensive use of national identities to help build brand images, and that such use can result in significant negative impacts to peoples and their cultures. Until recent times, the dominant themes for much of Australia’s international tourism advertising campaigns have been based upon male character types, Indigenous culture and landscape. The 2006 ‘Australian Invitation’ campaign which featured a young female model and use of the term ‘bloody hell’ created a media controversy. The research reported in this paper found that the majority of respondents liked and approved of the campaign, but a cluster analysis distinguished a group of approximately one third of the respondents who held negative attitudes towards it.     

The relationship between risk attitudes and heuristics in search tasks: A laboratory experiment

Experimental studies of search behavior suggest that individuals stop searching earlier than the optimal, risk-neutral stopping rule predicts. Two different classes of decision rules could generate this behavior: rules that are optimal conditional on utility functions departing from risk neutrality, or heuristics derived from limited cognitive processing capacities and satisficing. To discriminate between these possibilities, we conducted an experiment that consists of a search task as well as a lottery task designed to elicit utility functions. We find that search heuristics are not related to measures of risk aversion, but to measures of loss aversion.
