THE REGIONAL AGGLOMERATION IMPACAT OF JUST-I-TIME INPUT LINLAGES: EVIDENCE FROM THE SCOTTISH ELECTONICS INDUSTRY

There is no clear consensus as yet concerning the possible regional agglomeration impacts of Japanese Just-In-Time manufacturing techniques. This paper attempts to provide a theoretical structure to discussing such questions and then uses a logit model to analyse evidence from the Scottish Electronics Industry. The results provide support to the suggestion not only that the adoption of such techniques within the UK will encourage the shortening of input linkages, but also that this phenmenon is not restricted purely to the case of the automotive industry.     

关于中国货币政策的分析与建议

中国人民银行在货币政策战略方面已经取得了巨大成绩,但随着经济的日趋复杂,货币政策的有效性将会降低。实证研究表明中国需要维持对货币的盯住(a reference to money)战略以及加强利率在货币政策执行中的作用。我们建议采取折衷性战略,包括盯住若干指标,并将短期利率作为执行目标。应该赋予央行利率政策的自主权,在不远的将来实现这一目标不存在技术上的障碍。     

Investment in Africa's Manufacturing Sector: A Four Country Panel Data Analysis

Firm level data for the manufacturing sector in Africa, presented in this paper, shows very low levels of investment. The importance of profit effects on investment is investigated using a flexible accelerator, a specification based on the Euler equation and a simple generalisation of these specificiations. There are controls for firm fixed effects. It is shown that the profit effect is very similar for both the accelerator and Euler equation specifications. A comparison with other studies shows that, for small firms, the effect is much smaller in Africa than for other countries. Reasons for the relative insensitivity of investment to profits in African firms are suggested. For the most general specification tested there are no significant differences in the size of the profit effect across the four countries in the study.     

Japanese managerial and organizational learning

The article describes how the external forces of Japanese culture, industrial organization, and government intervention support managerial and organizational learning. It provides an overview of the culturally explicit philosophies that govern and stimulate learning in Japan, then explains how these philosophies are exhibited in Japanese management practice today. A model is presented which demonstrates the relationships among external forces, philosophical origins, management practice, and managerial and organizational learning. The conclusion is that managerial and organizational learning constitute one of Japan's most valuable competitive advantages. © 1998 John Wiley & Sons, Inc.     

Macro-economic determinants of consumer price knowledge: A meta-analysis of four decades of research

For the past four decades, dozens of researchers have studied consumer price knowledge, often with disagreements on the extent of consumer' ignorance about prices. While some of these disagreements have been attributed to research design variations among studies, no inquiry has yet been made on the role of the economic environment on consumer price knowledge. Nevertheless, environmental factors such as interest rates, unemployment, and economic growth may significantly influence consumers' knowledge of prices. Certain economic environments may therefore provide marketers with the ability to utilize pricing tactics which rely on limitations in consumers' knowledge of product prices. Using a meta-analytic framework, this paper synthesizes the results of 297 previous price knowledge studies to document the effects of inflation, unemployment, GDP growth, interest rates, country of study, and passage of time on consumer price knowledge. The meta-analysis results demonstrate that economic factors have considerable influence on explaining variations in consumer price knowledge. Managerial and public policy implications of the findings in light of turbulent economic environments are discussed.     

Effects of multimember districts on black representation in state legislatures

We look at the most general feature of multimember districts (MMDs) as compared to single-member districting (SMD) plans: the higher likelihood of submergence of minority voting strength. We focus on data on black legislative representation between 1977 and 1982 in the 11 states with more than 15% black populations, and compare states which use MMDs with those that use SMDs. We also examine changes in black representation in states which shifted from MMDs to SMDs. In addition, for MMD state legislative elections in eight North Carolina counties between 1978 and 1982, we examine in detail the nature of minority submergence including the lack of geographic representativity of the persons elected from MMDs. The counties we examine contain four of North Carolina’s largest cities and a substantial portion of North Carolina’s black population. Unlike almost all of the previously published literature on racial representation in MMDs, our study deals with state legislative races and not local elections.     

On the optimality of a minimum wage: New insights from optimal tax theory

We build a theoretical model to study whether a minimum wage can be welfare-improving if it is implemented in conjunction with an optimized nonlinear income tax. We consider this issue in a framework where search frictions on the labor market generate unemployment. Workers differ in productivity. The government does not observe workers' productivity but only their wages. Hence, the redistributive policy solves an adverse selection problem. We show that a minimum wage is optimal if the bargaining power of the workers is relatively low. However, if the government controls the bargaining power, then it is preferable to set a sufficiently high bargaining power.     

Purchase Intentions and the Dimensions of Innovation: An Exploratory Model

The ultimate success of new product R&D depends as much on customer acceptance as on technological breakthroughs. In this article, Susan Holak and Donald Lehmann focus on customer acceptance by exploring the manner in which the general attributes of Rogers (relative advantage, compatibility, complexity, divisibility and communicability) plus perceived risk combine to form the intention to buy an innovation. Results demonstrate a causal structure among these attributes and lead to various implications for R&D guidelines and product design.
