Communication technologies and spatial organization of multi-unit firms in metropolitan areas

Departing from traditional location theory (which treats a firm as a single-unit entity), in this paper we consider that each firm consists of multiple units that exchange information or services. Specifically, we develop a general equilibrium model of the city,in which each firm consists of a front-unit (e.g. business office) and back-unit (e.g. plant or back-office). Each front-unit interacts with all other front-units for the purpose of business communications, while each back-unit exchanges information or management services only with the front-unit of the same firm. Each firm must choose the location of its front-unit and back-unit optimally. The equilibrium spatial configuration of the city is determined as an outcome of interactions among all firms and households through competitive land and labor markets. We show that, depending on parameters, a variety of interesting patterns of metropolitan spatial organization emerges.     

EFFECTS OF REGIONAL COOPERATION AMONG SMALL AND MEDIUM-SIZED FIRMS ON THEIR GROWTH IN JAPANESE INDUSTRIAL CLUSTERS

We examine the effects of regional inter-firm cooperation on firm growth by estimating the firm growth function, using the data of a questionnaire survey for three major industrial clusters in Japan, namely, Tama, Kinki and Hokkaido. We focus on the specific content of cooperative activities for two aspects: that is, three production stages of R&D, commercialization, and marketing for cooperation and different types of alliance partners. The findings for our study areas demonstrate: i) vertical cooperation, the most prevalent with suppliers and customers, does not contribute to firm growth; ii) the clusters do not enjoy "urbanization economies arising from agglomerating a variety of different industrial sectors"; iii) the alliances with "universities" and "cross-industry exchange organizations" show positive effects on firm growth; and iv) both contributions and limitations are identified for the cluster-promotion policies in Japan.     

Dynamics of worker flows and vacancies: evidence from the sign restriction approach

This paper establishes robust dynamic features of the worker reallocation process in the US labor market. I use structural VARs with sign restrictions, which take the form of restricting the short‐run negative relationship between vacancies and unemployment (i.e., Beveridge curve). Despite the ‘weakness’ of these restrictions, they reveal a clear, unambiguous pattern that, when unemployment increases and vacancies drop, (i) both the separation rate and gross separations rise quickly and remain persistently high, (ii) the job finding rate and vacancies drop in a hump‐shaped manner, and (iii) gross hires respond little initially, but eventually rise. These results point to the importance of job loss in understanding US labor market dynamics. This pattern also holds with respect to different kinds of shocks that induce the same Beveridge curve relationship. This paper also considers the ‘disaggregate model’, which uses data disaggregated into six demographic groups and incorporates transitions into and out of the labor force. I show that the separation rate continues to play a dominant role among prime‐age male workers, while, for other groups, changes in the job finding rate are more important.

A Comparison of Regulatory Awareness and Green Supply Chain Management Practices Among Chinese and Japanese Manufacturers

Leading manufacturers in developed countries generally have high environmental awareness and implement proactive environmental management practices such as green supply chain management (GSCM). However, it is uncertain if smaller manufacturers in developed countries are more proactive than all manufacturers in developing countries. To understand this situation, we carried out surveys among small and medium‐sized Japanese manufacturers, leading Chinese manufacturers and traditional Chinese manufacturers. Statistical results show that leading Chinese manufacturers have the highest awareness of both domestic and international environmental regulations/policies, and implement all GSCM practices at the highest level. Leading Chinese manufacturers and Japanese manufacturers are aware of international environmental regulations/policies, but such awareness only motivates them to implement eco‐design practices. Traditional Chinese manufacturers have limited awareness of international environmental regulations/policies, but such awareness brings all types of GSCM practice. Such results can be helpful for different manufacturers in both developed and developing countries to develop suitable environmental strategies.

A REFUTATION OF THE COMMODITY EXPLOITATION THEOREM

This note is to show that the generalized commodity exploitation theorem put forward by Bowles and Gintis and Roemer is nothing but an alternative form of the Hawkins–Simon condition for given technical data, and that it has nothing to do with exploitation. That is, the Hawkins–Simon condition means a mere possibility of an economic system to produce a surplus in each commodity, and as such does not guarantee the existence of positive profits. To consider exploitation or the existence of positive profits, we need to introduce prices at which unequal exchanges may be carried out.     

INTANGIBLE INVESTMENT IN JAPAN: MEASUREMENT AND CONTRIBUTION TO ECONOMIC GROWTH

Following the approach of Corrado, Hulten, and Sichel (2005, 2006 ), we measure intangible investment and examine the contribution of intangible capital to economic growth in Japan. We find that the ratio of intangible investment to GDP in Japan has risen during the past 20 years and now stands at 11.1 percent, which is lower than the ratio estimated for the U.S. in the early 2000s. The ratio of intangible to tangible investment in Japan is also lower than equivalent values estimated for the U.S. In addition, we find that, in stark contrast to the U.S., where intangible capital grew rapidly in the late 1990s, the growth rate of intangible capital in Japan declined from the late 1980s to the early 2000s. Our conclusions regarding intangible investment in Japan remain largely unchanged even if, using data with respect to firm-specific resources, we take on-the-job training into account.     

Does Geographical Agglomeration Foster Economic Growth? And Who Gains and Loses from It?

This paper proposes a two-region model of endogenous growth, which is a natural combination of a core–periphery model à la Krugman and an endogenous growth model à la Grossman/Helpman/Romer. The innovation activity in the R&D sector involves knowledge externalities among skilled workers. Our analysis supports the idea that the additional growth spurred by agglomeration may lead to a Pareto-dominant outcome such that, when the economy moves from dispersion to agglomeration, innovation follws a much faster pace. As a consequence, even those who stay put in the periphery are better off than under dispersion, provided that the growth effect triggered by the agglomeration is strong enough.

New Economic Geography: An appraisal on the occasion of Paul Krugman's 2008 Nobel Prize in Economic Sciences

Paul Krugman has clarified the microeconomic underpinnings of both spatial economic agglomerations and regional imbalances at national and international levels. He has achieved this with a series of remarkably original papers and books that succeed in combining imperfect competition, increasing returns, and transportation costs in new and powerful ways. Yet, not everything was brand new in New Economic Geography. To be precise, several disparate pieces of high-quality work were available in urban economics and location theory. Our purpose in this paper is to shed new light on economic geography through the lenses of these two fields of economics and regional science.
