Comparative study on the relationship between just-in-time production practices and operational performance in manufacturing plants

This study analyzes the differences in approaching JIT production across countries in order to identify alternative paths to high manufacturing performance. We applied ANOVA and regression techniques to the database of High Performance Manufacturing Project to examine the similarities and differences across countries in JIT implementation and the effect of JIT production practices on operational performance. The results indicated that JIT production practices were implemented in different ways across the countries. We found that the relationship between JIT production practices and plant performance is contingent on the national context and infrastructure practices in quality and workforce management. JIT delivery by suppliers, JIT layout, and setup time reduction were found to be the most effective approaches to improve cost, delivery, and flexibility. This study highlights the important role of shop-floor communication and information sharing, which should be focused for maximizing the benefits of JIT implementation.     

Crisis and Creative Destruction: Cases of Korean and Japanese Stock Markets

In this essay, we investigate the contrasting performance of Korean and Japanese stock markets before and after the East Asian currency crisis. The Korean stock markets showed a sharper decline and a faster recovery than the Japanese stock markets. First, we theoretically explain these contrasting movements of stock markets by explicitly modeling and adding some new elements to the idea of IT revolution in Greenwood and Jovanovic (Amer. Econom. Rev. 89, 1999, 116–122). Then we empirically prove that the theoretical model in this paper has some quantitative support by considering the level of monthly stock market capitalization and the return on daily stock index in Korea and Japan.JEL Classification Code: F43     

Trans-boundary Pollution and Brain Drain Migration

The economic effects of international brain drain migration in the presence of trans‐boundary pollution are analyzed. In autarky, both skilled and unskilled workers are expected to migrate from the less developed foreign country to the developed home country, if permitted. Surprisingly, under certain conditions, all workers, apart from skilled foreign ones, will gain (lose) from the migration of unskilled (skilled) foreign workers. Moreover, if skilled foreign workers are employed as unskilled domestic workers, then skilled foreign workers will gain but unskilled workers in both countries will lose. Whether or not skilled domestic workers will gain depends on the magnitude of the pollution spillover parameter. Brain drain migration persists under free trade if the demand for manufactured goods is strong.     

Marketing Channels and Retail Store Density in East Asia*

By measuring retail store density with regard to population, several studies have indicated that marketing channels in Asia are different from those in the USA and European countries. The present paper investigates to what extent a model similar to Flath and Nariu (1996) can empirically predict retail densities in Japan and China. The results suggest that the secular decline in the number of retail stores in Japan primarily results from the proliferation of car ownership and the expansion in the average size of a dwelling. We also demonstrate that the model accounts for the large variations in China's retail density.     

An implementation of the HJM model with application to Japanese interest futures

In this paper, we propose a new specification of the forward rate model of Heath, Jarrow and Morton [5] and apply it to the Japanese 3 month interest rate futures. Our empirical result shows that the model we propose can capture the forward interest rate movement.     

A comparative analysis of new product development by Italian and Japanese manufacturing companies: A case study

Based on survey data from Italian and Japanese companies, six measurement scales are developed for practices, process, strategic guide, and capabilities for new product development as potential determinants of its financial performance, that is, attainment of profit goals and revenue goals. By employing a regression model with a country dummy variable, the differential determinants of financial goals attainment between Italian and Japanese samples are estimated. A significant difference can be found in the impact of new product development capabilities on profit goals attainment only. Then, we evaluate the level of improvement in explanatory power by dividing the pooled sample into two and enabling regression coefficients to take different values, and find no evidences of the significant improvement. Technology and marketing capabilities concerning new product development are demonstrated to be overwhelmingly important to financial performance.     

International Trade and Volume Patterns under Quasilinear Preferences

We formally analyze the pattern and volume of trade by embedding quasilinear preferences in the standard perfectly competitive, two‐factor, two‐good, two‐country trade model. Quasilinear preferences deliver a natural partition of the two goods into a luxury and a necessity, and preserve the validity of the Heckscher–Ohlin and Heckscher–Ohlin–Vanek theorems. In addition, the predicted factor content of trade under quasilinear preferences is smaller (larger) than the predicted factor content of trade under homothetic preferences if and only if the luxury good is capital (labor) intensive. This result offers a novel explanation for the “missing‐trade” mystery.     

Diffusing the Cloud: Cloud Computing and Implications for Public Policy

Cloud Computing is rapidly emerging as the new information technology platform. It is, however, much more than simply a new set of technologies and business models. Cloud Computing is transforming how consumers, companies, and governments store information, how they process that information, and how they utilize computing power. It can be an engine of innovation, a platform for entrepreneurship, and driver of corporate efficiency. While an increasingly commonly term, confusion remains over what exactly constitutes Cloud Computing, how the markets are unfolding, and what forces will drive their evolution and diffusion. This paper provides an overview and conceptual tools for business leaders, policymakers, and non-specialist scholars to identify, distill, and easily understand the core aspects of how Cloud Computing service markets are developing, and how an array of policy issues will influence how this new computing platform unfolds across the world.     

Quality management practices and competitive performance: Empirical evidence from Japanese manufacturing companies

This paper presents the results of an empirical study on the relationship between quality management practices and competitive performance in Japanese manufacturing companies. The data was gathered from two surveys including the common sample of twenty-seven Japanese manufacturing companies in the 1990s and the 2000s. Statistical techniques are used to compare the degree of implementation of the eleven quality management practices and their impact on different dimensions of competitive performance between two periods. Findings of this study highlight the stability and consistency of the Japanese quality management, which can be used as one of the strategic weapons for maintaining competitive advantage of Japanese manufacturing companies.     

Welfare Effects of Reducing Home Bias in Government Procurements: A Dynamic Contest Model

This paper models an international contest for government procurement as a dynamic game between a domestic firm and a foreign firm. We show that trade liberalization, in the form of a reduction in bias against the foreign firm, improves both domestic and global welfare if (i) either the foreign firm's profit is sufficiently large or (ii) the initial degree of home bias is sufficiently small. If the initial home bias is large, a small reduction in the bias may reduce welfare.
