Asset illiquidity and market shutdowns in competitive equilibrium

This paper introduces asymmetric information in a competitive asset market into a dynamic general-equilibrium model with borrowing constraints. In the presence of borrowing constraints, asset sales become a crucial means for agents to finance opportunities to invest in new assets. In this environment, reduced asset sales due to asymmetric information lower the economic growth rate if agents invest in new assets. The volume of asset trade, however, becomes zero if and only if agents stop investing in new assets because of sufficiently low aggregate productivity. A low economic growth rate with a market shutdown is solely due to low aggregate productivity without any role of the market shutdown.     

Spatial inequality, globalization, and footloose capital

This paper shows the equivalence of spatial inequalities in industrial location and in income by revisiting the home market effect (HME) without any homogeneous good based on a reconstructed footloose capital model. In this simple framework, spatial inequalities in industrial location and in income are the HMEs in terms of firm share and wage, respectively. We show that the larger country has a more-than-proportionate share of firms and a higher wage. Furthermore, both the wage differential and the industrial location in the larger country evolve in an inverted U-pattern when transport costs decline. Finally, we analytically examine the effects of trade liberalization on the welfare and show that both countries may gain from globalization.     

Mobile capital and the home market effect

Abstract Most existing studies examine the home market effect (HME) in a framework with immobile labour as the only production factor and the assumption of a freely traded homogeneous good is known to be crucial for the HME to emerge. This study explores the HME in the presence of mobile capital by use of a footloose capital model allowing for positive transport costs of the homogeneous good. The mobile capital generates a channel to offset the trade imbalance of a country. As a result, the HME always appears for arbitrary transport costs in both sectors of differentiated and homogeneous goods.     

Upstream and downstream pollution taxations in vertically related markets with imperfect competition

When two markets are vertically related, the government can control pollution at the upstream as well as the downstream market levels. This paper employs the stylized model of input price discrimination and compares the effectiveness of upstream and downstream pollution taxations. We consider the situation in which downstream firms have heterogeneous abatement technologies and an upstream monopolist performs input price discrimination against them. In order to mitigate pollution, the government imposes input tax on the intermediate inputs and emission tax on the pollutant. We show that the degree of input price discrimination decreases with a rise in the input tax and increases with a rise in the emission tax. We further examine the effect of a green tax reform in which the government changes the source of taxation from input tax to emission tax. We argue that although this green tax reform may reduce the tax revenue of the government, it will certainly increase social welfare.      

AGGLOMERATION ECONOMIES IN JAPAN: TECHNICAL EFFICIENCY, GROWTH AND UNEMPLOYMENT

This paper examines if the effects of agglomeration economies are manifested in technical efficiency and generate faster economic growth and higher (lower) levels of employment (unemployment). Using the prefecture level data for each of the two-digit groups of industries in Japan, it estimates a region-specific technical efficiency index based on the stochastic frontier production function framework. The factor analysis shows that in most of the industry-groups, efficiency has a positive association with external scale variable(s). Though the relationship is not very strong, it would be erroneous to ignore the effect of agglomeration economies on efficiency. For some light goods industries, the agglomeration effect is relatively stronger. Economic growth varies positively with external scale variable(s) and the unemployment rate tends to fall with respect to growth and concentration. This suggests that measures against industrial concentration may be counter-productive, particularly in the context of globalization when countries greatly need to raise productivity.     

'Total factor productivity vs. realism' revisited: the case of the South Korean steel industry

This paper presents key features of the development of the SouthKorean steel industry through the critical examination of anarticle by Truett and Truett. Despite their claim to exhibit‘realism’ by use of a translog cost function, theirmethodology has strong affinities with the methods of measuringtotal factor productivity growth, which have long been knownas invalid but continue to be applied not least to the experienceof East Asian countries. It will be argued that the theoreticaland empirical flaws involved with these methods invalidate theirresults and corresponding policy implications. Above all, byshowing that the assumptions for their calculation do not holdin terms of the economic conditions of the industry, the paperpoints to a different understanding of ‘realism’than that conceived by and for their study.     

Obstacles to emergence of high/new technology parks, ventures and clusters in Japan

The feasibility of and obstacles to government policies to promote high/new technology (HNT) parks, ventures and clusters are examined mainly in regard to the value systems in the administration and businesses (AB) world and the science and technology (ST) world. Using the language analysis method developed in the philosophy of science, semantic gaps concerning science and research between the two worlds were analyzed and demonstrated as leading the Japanese ST policies into contradictions. Cultural factors such as value gaps between the two worlds are shown to be responsible for the unsuccessful outcome of the ST policies. It is advised to reverse the current ST policies as a short-range policy and to foster ST potential in local areas by renovating traditional fermentation and other techniques and starting up ST-promoting tourism enterprises as a long-range policy.     

Fuzzy operational approach to analysis of Delphi forecasting

Delphi forecasting exploits the intuitive side of judgment, but there has been little attempt to analyse Delphi opinions quantitatively as a result of, among other things, severe methodological obstacles. Fuzzy theory provides a possible approach, and here is used to examine the relationship between experts' views on the degree of importance and year of the breakthrough they are forecasting. The underlying model assumes that the experts also estimate the possibility and range of advancing the year of breakthrough, given that important potential breakthroughs will have more resources diverted to them, and that this will affect the estimated dates (although the experts may not necessarily be aware that they are doing this). Graphical and analytical representations of this process are described which derive an estimate of the technological feasibility of the breakthrough as a function of time, from successive rounds of estimates of importance and year of breakthrough.     

Does Globalization Foster Economic Growth?

This article examines the effects of globalization, by especially focusing on the relaxation of local equity requirements (LERs) in developing countries. By constructing an endogenous growth model, where profit leakage to the South through LERs plays a key role, we obtain the following results. First, the relaxation of LERs in the South drives the relocation of firms from the North to the South, yielding a U‐shaped growth rate. Second, our numerical simulations suggest that a sufficient relaxation of LERs is beneficial for the South, although the shared profit of joint ventures is maximized through the use of LERs.     

Multimarket contact in continuous-time games

This paper investigates whether multimarket contact is effective in increasing the value of collusion. We show that for any discount rate, the set of equilibrium payoffs (average per market) expands through multimarket contact in continuous-time games.
