Indirect network effects and the impact of trade liberalization: A note

In this note, we examine how trade liberalization affects production structure in the presence of indirect network effects (hardware/software systems). For these purposes we construct a simple two-country model of trade with two incompatible hardware technologies. It is shown that, given that both types of hardware exist before trade liberalization, liberalization and increased intra-industry trade in software products may reduce the variety of hardware technology via intensified network effects. It is also shown that, contrary to the findings of previous studies on intra-industry trade, some consumers may become worse off as the result of trade.     

On the de-facto convex structure of a least square problem for estimating the term structure of interest rates

We will show that the objective function of a constrained least square problem for estimating the term structure of the interest rates discussed in [4] is in fact convex in the feasible region defined by a set of linear constraints. This means that the algorithm developed in [4], which uses a linear or quadratic approximation to the objective function, generates a globally optimal solution of a constrained least square problem.     

Relative Performance of U.S. and Japanese Electricity Distribution: An Application of Stochastic Frontier Analysis

This paper estimates and compares the technical efficiency of the U.S. and Japanese electric utilities during the period 1982–1997 using a stochastic frontier analysis. Our focus is on electricity distribution services of major investor-owned utilities. We employ translog input distance functions to represent the technology of electricity distribution. Empirical results show that after controlling for environmental variables, on average, the Japanese electric utilities are more efficient. It is shown, however, that some U.S. utilities are as efficient as the most efficient Japanese utilities, indicating that the estimated frontier is not necessarily dominated by Japanese utilities.An erratum to this article can be found at     

Agricultural Productivity,Business Services,and Comparative Advantage

By explicitly incorporating both the intermediate business service sector and non-homothetic preferences, this study develops a two-good (the agricultural good and the manufactured good) model of trade that captures the role of agricultural productivity, which deepens the division of labor in the manufactured good sector. The level of agricultural productivity is found to determine the structure of comparative advantage: the country that has an absolute advantage in the agricultural sector also has a comparative advantage in the manufactured good sector.     

Communications networks and virtual economic integration: The case of three countries

This paper proposes a three-country model of trade that captures the role of communications networks which enhance trade in business services. The interconnectivity of country-specific networks is found to determine the structure of comparative advantage in the good that requires business services provided via networks. In connected countries, producers of that good benefit from the growing connectivity of business services providers. It is also shown that the third country which is unconnected to the interconnected networks may be worse off from trade.The first author is grateful for the support of the Telecommunications Advancement Foundation.     

A simple model of service trade with time zone differences

This note proposes a two-country model of service trade that captures the role of time zone differences as a determinant of trade patterns. It is shown that the utilization of communication networks induces dramatic change in industrial structure due to firms taking advantage of time zone differences.     

A simple model of foreign brand penetration under monopolistic competition

The main purpose of this study is to illustrate, with a simple monopolistic competition trade model, how trade liberalization (i.e., a decline in trade costs) can affect domestic entrepreneurs’ decision between providing domestic or foreign brands, and thus the degree of foreign brand penetration. It is shown that, as trade costs decrease, more entrepreneurs choose to provide foreign brands. Furthermore, the shift to foreign brands is shown to magnify the negative impact of trade liberalization on the profits of firms selling domestic brands.     

The Effects of CEO Trustworthiness on Directors’ Monitoring and Resource Provision

This research investigates the interplay between leadership styles and institutional corporate social responsibility (CSR) practices. A large-scale field survey of managers reveals that firms with greater transformational leadership are more likely to engage in institutional CSR practices, whereas transactional leadership is not associated with such practices. Furthermore, stakeholder-oriented marketing reinforces the positive link between transformational leadership and institutional CSR practices. Finally, transactional leadership enhances, whereas transformational leadership diminishes, the positive relationship between institutional CSR practices and organizational outcomes. This research highlights the differential roles that transformational and transactional leadership styles play for a firm’s institutional CSR practices and has significant implications for theory and practice.
