PRODUCT QUALITY,REPUTATION, AND MARKET STRUCTURE*

In a repeated game in which firms simultaneously choose price and product quality, but quality is observed only after consumption takes place, equilibria exhibiting high quality may exist in oligopoly markets even when the low‐quality one is a unique equilibrium outcome in monopoly and competitive markets. Oligopolists can sustain high quality through the threat of both a loss of reputation and a breakdown in tacit collusion. While we abstract from other reasons that market structure might affect product quality, we show that the inverted‐U shaped relationship between feasible quality and market structure is robust to several generalizations of the model.     

International Entrepreneurship Research: What Scope for International Business Theories?

International entrepreneurship (IE) research has commonly neglected significant perspectives applied by international business scholars. Explanations for the emergence and growth of international entrepreneurial firms largely focus on the resource-based view and the network perspective. While these approaches are useful, we suggest that IE would benefit significantly from a greater emphasis on its international nature. Therefore, theories of international business should be employed in conjunction with other approaches in order to appropriately emphasize the international character, holistically study the IE notion, and considerably broaden the scope of IE examination. Suggestions for relevant research directions are discussed.     

Beyond brainstorming: The effectiveness of computer-mediated communication for convergence and negotiation tasks

Although a considerable body of research in information systems has established that computer-mediated communication (CMC) is beneficial for brainstorming (idea generation) tasks, less is known about its effectiveness for more complex decision-making tasks. This paper reports the results of two experiments comparing the performance of face-to-face and CMC teams in decision-making tasks that move beyond brainstorming. In the first experiment, the performance of face-to-face and computer-mediated teams was compared in two tasks: one requiring participants to engage in convergent thinking and a second brainstorming task requiring divergent thinking. Consistent with predictions derived from McGrath's task circumplex model, the results of experiment one reveal that participants using computer-mediated communication perform significantly better than those interacting face-to-face on the divergent (brainstorming) task. On the convergent task, computer-mediated and face-to-face teams performed equally well; i.e., there was not a significant difference in their performance. In the second experiment, the performance of face-to-face and computer-mediated teams was again compared in two tasks: an integrative negotiation task and an idea-generation task. The results of the second experiment were similar to those of experiment one, in that computer-mediated teams significantly outperformed face-to-face teams in the idea-generation task, while computer-mediated and face-to-face teams performed equally well on the integrative negotiation task. These experiments contribute to the literature by shedding additional light on the conditions under which computer-mediated communication is as effective as, and in some cases more effective than, face-to-face interaction.     

Efficient Insurance Contracts under Epsilon-Contaminated Utilities

This paper analyses the qualitative properties of optimal contracts when agents have multiple priors and are uncertainty averse in an infinite state space framework. The case of the epsilon-contamination of a given prior, a basic tool in robustness theory is fully developped. It is shown that if both agents have strictly concave utility index, then if the insurer is less uncertainty averse than the insured, he provides a full insurance contract above a deductible for high values of the loss.     

An Examination of the U.S. Public Accounting Profession’s Public Interest Discourse and Actions in Federal Policy Making

Participation in the political process by the United States public accounting profession often blurs the role of the profession as advocates for the public interest with its role as advocates for its own private interests. In this study, we draw from prior theoretical and empirical work to investigate recent federal political activities of the public accounting profession to shed light on these sometimes contradictory roles. In particular, we investigate ten contemporary regulatory issues of interest to the AICPA. We analyze 36 AICPA legislative advocacy letters related to these issues that were provided to federal policy makers. In addition, we analyze the public accounting profession’s federal lobbying reports that were submitted during this same time period. The analysis allows us to assess the public interest discourse present in the AICPA legislative letters as well as the extent of political action taken by the profession related to these issues based on the profession’s lobbying efforts. Our analyses (1) demonstrate that the profession’s discourse and actions often reflect both public and private interest motivations, (2) allow us to categorize the profession’s advocacy efforts as arising from specific motivations, and (3) show that the profession’s public interest arguments used to advocate for their policy positions change depending upon the specific legislative issue being considered.     

SMEs’ Financing and Banks’ Profitability: A “Good Date” for Banks in Ghana?

Small and medium enterprises (SMEs) are the core of most economies and are a major source of economic growth. In recent times, banks have been actively involved in the financing of SMEs through the provision of loans to this sector. This paper investigates the impact of SMEs financing on banks’ profitability in Ghana. The study employed the fixed effect model as the main regression tool. The study result reveals that SMEs significantly contribute to banks’ profitability in Ghana. Interestingly, transaction cost in administering SME loans was insignificant in all the models. Higher inflation reduces the real value of the loan and erodes the interest returns on the total credit to the SMEs. Conversely, growth of GDP enhances the growth of the bank profit.     

Protecting Biotechnology IPRs in Developing Countries: Simple Analytics of a Levy Solution

High transaction costs and an absence of institutional infrastructure in developing countries prevent comprehensive enforcement of intellectual property rights and generate obstacles to the adoption of genetically modified (GM) crop technology. Governments of developing countries that are members of the World Trade Organization are faced with two options when licensing GM crop technology: (1) attempt to regulate GM crops to the standards of the Agreement on Trade‐Related Aspects of Intellectual Property (TRIPS) or (2) allow a black market in GM seeds and risk trade retaliation from the GM innovator's host country through a TRIPS trade complaint. This paper develops a conceptual model that frames the adopting country's range of licensing options, including a new levy system, and derives welfare measures for each option. The model illustrates how a levy on GM technology can be a welfare‐increasing policy for developing countries, and the operation of a levy is discussed. The conceptual model is applied to Brazil's soybean market and quantitative economic surplus measures are estimated within a calibrated welfare model for a range of licensing scenarios. The model's results suggest that a levy may interfere with the long‐term prospects for innovators to collect monopoly rents in adopting countries.
