Inertia in the key currency

This paper empirically analyzes inertia in the position of the dollar as the key currency. We extend a money-in-the-utility model to one with parallel international currencies. We use an extended model to estimate a parameter in the utility function. Also, given the estimated parameter, we simulate a relation between depreciation and share of the dollar. The result indicates that the share of the dollar will not decrease even if the dollar depreciates at a moderate rate. Thus the dollar will keep its position as the key currency – inertia works in the key currency.     

RJVs in product innovation and cartel stability

Abstract. We characterise the interplay between firms' decision in product development undertaken through a research joint venture (RJV), and the nature of their ensuing market behaviour. Participant firms in an RJV face a trade-off between saving the costs of product innovation by developing similar products to one another, e.g., by sharing most of the basic components of their products, and investing higher initial efforts in product innovation in order to develop more distinct products. We prove that the more the firms' products are distinct and thus less substitutable, the easier their collusion is to sustain in the marketing supergame, either in prices (Bertrand) or in quantities (Cournot). This gives rise to a non-monotone dependence of firms' product portfolio upon their intertemporal preferences.

A comparative analysis of Japanese firm productivity： Solow residual and Malmquist productivity index

For some time, two major kinds of Total Factor Productivity （TFP） have existed independently of each other： the Solow residual and the Malmquist Productivity Index （MPI）. The Solow residual was introduced in macro economic growth models, and the MPI has been used in micro economics and management studies. As both indices were developed independently, few studies utilize both together and compare the results. This paper uses the same data to compare the two productivity indices by setting to determine the economic implications of combining the two indices. We discovered that we could decompose TFP with each aspect of the Soiow residual and MPI. We could then interpret their relationship in the business cycle. Our results indicated that the frontier shift in MPI of Japanese firms often occurred when the Solow residual increased, meaning that improving oroductivitv with the Solow residual could be generated by a firm that could shift new production frontiers.     

Interdependence and Managing Conflict with Sub-Contractors in the Construction Industry in East Asia

In contrast to traditional assumptions about Asian conflict management, interdependence may induce cooperative approaches to conflict rather than avoidance or competition. Findings from supervisors on 216 subcontractors in Korea, Japan, and Hong Kong support the hypotheses that interdependence leads to cooperative conflict which results in constructive conflict which in turn helps the subcontractor contribute to the main contractor. However, competitive and avoiding conflict were found to be useful in Taiwan. Results were interpreted as suggesting that the theory of cooperation and competition offers the potential for strengthening conflict management in East Asia and that cooperative conflict, rather than avoiding, may reinforce feelings of interdependence in East Asia.     

Total Factor Productivity of the Japanese Rice Industry

We calculate partial factor productivity and total factor productivity (TFP) indices for rice production using panel data across 42 Japanese prefectures from 1996 to 2006, and perform panel unit root tests of TFP convergence across prefectures. We find that during this period, the partial factor productivity growth rates for capital, land and materials stagnated at the aggregate national level, as did the TFP growth rate, despite a large increase in labor productivity. We also identify evidence of a convergence in TFP across Japanese prefectures.     

Managing for customers and employees in Hong Kong: The quality and teamwork challenges

Service marketing, total quality management, and human resource management researchers have proposed that employee teamwork is a foundation for service quality. North American research suggests that developing cooperative relationships and constructive controversy among employees can empower employees to serve customers and to strengthen their work relationships and commitment to the organization. Chinese employees in an American-style restaurant in Hong Kong were interviewed on specific incidents that affected service quality. Correlational and structural equation results support the hypotheses that cooperative goals help employees discuss their diverse views open-mindedly and that this constructive controversy results in quality customer service. Competitive and independent goals were largely negatively correlated with dynamics and outcomes. Results were interpreted as suggesting that service teams should develop strong cooperative goals and the skills and procedures of constructive controversy. Deutsch's theory of cooperation and competition, although developed largely through North American research, seems useful for understanding and developing service quality teamwork in Asia.
