International Economies of Scale and the Gains from Trade

In this paper, we present a two-country trade model with external economies of scale that emerge on an international level but are partially localized in each country. First, we show that the larger country exports the good produced in an industry with external economies of scale in the trading equilibrium. Second, we investigate the welfare effects of trade for the following two cases: (I) the case where external economies are completely localized in autarky; (II) the case where external economies are internationally effective in autarky. In case (II), it is shown that trade can be welfare-decreasing for both countries.     

R&D,Firm Size and Innovation Outputs: Are Japanese Firms Efficient in Product Development?

Although Japanese firms in various industries enjoyed outstanding success during the 1980s, the recent economic news has been less favorable. Like their American counterparts, Japanese managers have faced difficult decisions regarding plant closures, layoffs, and moving production facilities overseas. Many Japanese business leaders attribute the innovation successes of the 1980s, at least in part, to economies of scale resulting from increases infirm size. If this assertion holds true, the current economic climate in Japan seems certain to result in diminished economies of scale for innovative activities. Ryuhei Wakasugi and Fumihiko Koyata test this assertion in a statistical study of the innovation efficiency of Japanese electrical machinery firms. In other words, their study explores whether the hypothesized economies of scale apply to the innovation inputs and outputs of these firms. They examine the manner in which R&D expenditures, patent applications, and product developments relate to the size of Japanese electrical machinery firms during the late 1980s and early 1990s—a period marked by high levels of innovative activity among these firms. For the Japanese electrical firms in this study, innovation inputs that is, R&D expenditures—increase in greater proportion than firm size. In other words, the larger firms in this study pursued their innovation efforts more aggressively than did the smaller firms in the study. In terms of R&D expenditures, however, the study does not reveal any resulting economies of scale for either patent applications or product developments. Similarly, analysis of the data in this study does not identify any economics of scale for product developments as a result of increases in firm size. In fact, the only economies of scale identified in the study involve firm size and the number of patent applications. In general terms, the statistical evidence in this study does not support the hypothesis that an increase in firm size improves the efficiency of innovation activity. To put this another way, the study does not provide evidence to support the hypothesis of economies of scale in product development.     

A cross‐country study on the relationship between financial development and earnings management

This study investigates whether a country's level of financial development is associated with earnings management in an international setting. Financial development is likely to heighten the monitoring and scrutiny of accounting numbers because of strengthened investor protection laws and regulations as well as sophisticated market participants. Therefore, we first hypothesize that both accrual‐based and real earnings management decrease with greater financial development. However, research shows that managers tend to apply real earnings management, instead of accrual‐based earnings management, under strict accounting standards, regulations, and close auditor scrutiny. Thus, we explore the alternative hypothesis that accrual‐based earnings management decreases but real earnings management increases along with higher financial development. We examine the relationship between financial development and both types of earnings management using 56,830 observations in 37 countries covering the period 2009–2012. The results indicate that both types of earnings management are more restrained under higher levels of financial development.     

Algebra for Enterprise Ontology: towards analysis and synthesis of enterprise models

Enterprise modeling methodologies have made enterprises more likely to be the object of systems engineering rather than craftsmanship. However, the current state of research in enterprise modeling methodologies lacks investigations of the mathematical background embedded in these methodologies. Abstract algebra, a broad subfield of mathematics, and the study of algebraic structures may provide interesting implications in both theory and practice. Therefore, this research gives an empirical challenge to establish an algebraic structure for one aspect model proposed in Design & Engineering Methodology for Organizations (DEMO), which is a major enterprise modeling methodology in the spotlight as a modeling principle to capture the skeleton of enterprises for developing enterprise information systems. The results show that the aspect model behaves well in the sense of algebraic operations and indeed constructs a Boolean algebra. This article also discusses comparisons with other modeling languages and suggests future work.     

AN ANALYSIS OF TRANSBOUNDARY POLLUTION AND THE GAINS FROM TRADE: RECONSIDERATION

Abstract.  This paper investigates the effects of transboundary pollution on trade and welfare in a two-country, two-good, one-factor model in which pollution is treated as a negative cross-industry externality. It is shown that trade may improve countries' natural environment and consequently raises the countries' welfare if a comparative advantage in a pollution-producing good is held by a country that greatly surpasses the other in pollution abatement technology. This result has not been obtained from existing models of this type.     

Do the Rich Save More in Japan? Evidence Based on two Micro Data Sets for the 2000s

Using two household surveys, this paper investigates whether the saving rates of richer households are higher than those of poorer households in Japan. We construct a number of proxies for lifetime wealth, including those original to this study, and find marginally positive correlations between saving rates and lifetime wealth for working age households. We further find that the relationship between saving rates and lifetime wealth differs depending on the life stage of individual households. Older households with higher lifetime wealth appear to be dissaving to some extent, which is more or less consistent with the lifecycle model of consumption.     

Vertical specialization in North–South trade: Industrial relocation,wage and welfare

This paper presents a North–South trade model with vertically linked industries and examines how declining costs of trade across stages of production encourage vertical specialization and affect wages and welfare. As trade costs fall below a threshold, the production of all final goods relocates to the South and vertical specialization emerges. In some industries, production of intermediate goods also relocates against comparative costs because of benefits of co‐location, and further declines in trade costs lead to reshoring. A country may temporarily lose from falling trade costs, but both countries can be better off after trade costs fall sufficiently.     

Impossibility Theorems with Interpersonally Comparable Welfare Levels: The "Extended Sympathy Approach" Reconsidered

We re-examine a type of interpersonal welfare comparison, called the "extended sympathy" approach, which Arrow (1977), Hammond (1976) and Roberts (1980a) introduced in order to escape from Arrovian impossibility theorems. In particular, we extend the positional dictatorship theorem due to Roberts to the case where the domain of social choice rules satisfies the axiom of identity. We show that there is a positional dictator if the rule with the domain satisfies independence, Suppes unanimity and monotonicity

Environmental Management in Japan: Applications of Input–Output Analysis to the Emission of Global Warming Gases

Environmental management requires, among other things, the incorporation of environmentally friendly technologies into production processes of environmentally friendly technologies into production processes at the producer level and the adoption of energy consumption patterns which save energy use at the household level. The systemwide approach involving both technology choice and consumer preference seems particularly essential for controlling the total emission of global warming gases. CO₂ and other global warming gases, as well as certain pollution causing gases, are produced when fossil fuels are burnt; and the consumption of fossil fuels occurs in both the production and consumption of goods and services. In this paper we discuss how input–output analysis can be used to estimate the entire production and consumption of global warming gases conditional on production technology and consumer preferences. We also present estimation results and their application to some environmental management issues in Japan. © 1997 John Wiley & Sons, Ltd.
