Bank diversification and monetary policy

Using bank-level data in Asia, we examine the relationship between the effectiveness of monetary policy and the business diversification of banks. We find that bank diversification enhances the effect of monetary policy.     

Subsidy competition and imperfect labor markets

This study presents a two‐country model of subsidy competition for manufacturing firms under labor market imperfections. Because subsidies affect the distribution of firms, subsidies influence unemployment rates and welfare in both countries. We show that when labor market frictions are high, subsidy competition is beneficial, although subsidies under subsidy competition are inefficiently high. In the coordinated equilibrium, the supranational authority provides a subsidy to firms that equal the expected total search costs, which increases the number of firms relative to laissez‐faire and improves welfare relative to laissez‐faire and subsidy competition. Finally, we find that a rise in a country's labor market frictions raises the equilibrium subsidy rate, affects unemployment rates, and lowers welfare.     

市场化进程中社会资本还能够充当保险机制吗?——中国农村家庭灾后消费的经验研究

本文研究了在中国农村的市场化过程中,社会资本为遭受自然灾害的家庭的消费平滑提供保险的作用。我们基于2002年中国家庭收入调查(CHIPS)的农村数据进行经验研究,结果显示,互助、公民参与及信任这三种社会资本并没能帮助中国农村家庭抵御自然灾害对于消费的冲击。我们的发现并不依赖于同村家庭遭受自然灾害的同质性程度。我们进一步找到证据表明:社会资本在帮助农户分担风险和平滑消费上的作用随着市场化的深入而减弱。     

Effective Rental Housing Demand in the Tokyo Metropolitan Region

This paper reports on the estimation of housing demand for tenants in Tokyo Metropolitan Region using household level data for 1993. The results indicate that the rental housing demand is inelastic with respect to permanent income and price, with coefficients as 0.31 and -0.093 respectively. Other important variables, which determine housing demand for tenants are length of stay and type of household. Larger households demand more housing. However, keeping the size of household constant, households with elderly members have higher demand for housing. The only exception to the rule is households formed with members not belonging to same nucleus family demand less housing.     

Capability building through innovation for unserved lower end mega markets

Although product innovation for unserved lower end mega markets in large developing countries has been recognized as an opportunity for improving the competitiveness of local firms, limited research has been conducted that explicitly explores how innovation capabilities can be built for these markets. This study investigates Tata Motors' Nano as an exploratory case of building innovation capabilities. This paper shows that the building of innovation capability could be achieved through creating a process that overcomes ‘the deficiency problem’ in generating radically cheap priced original products.The study's contribution to the literature is that it addresses issues of building local firms' innovation capabilities through creating original products for the unserved lower end market, in which advanced country firms have limited experience.Nano, as an unprecedented innovation in the automobile industry, reveals a path to building innovation capability that has not previously been observed. We show that detailed processes involved in generating an original product for the lower end market provide insights on the strategy in terms of target price setting, initiating innovation process overcoming ‘the deficiency problem’, and creation of complementary resources.     

Market Size and Firm Location in a Service Industry

This paper investigates the welfare effects of firm location in a service industry. We consider the situation where firms determine their locations in either of two regions with a difference in market size. From the viewpoint of the consumers' welfare, there are too few firms in the large market and too many in the small market. However, from the viewpoint of the producers' and social welfare, the opposite is true. Further, an increase in the difference in market size is unambiguously unfavorable for the producers. On the other hand, such an increase is favorable for the consumers and the economy as a whole.     

Role of TFP in China's Growth*

This paper uses the dual approach to growth accounting to examine the role of total factor productivity (TFP) in recent Chinese growth. Most previous growth accounting studies on China have followed the primal approach, which depends heavily on the national income accounts. Unfortunately, despite efforts to rectify them, Chinese national income accounts data continue to have problems that affect primal approach growth accounting results. The dual approach, in contrast, allows independent price information to play a role. Recent research has focused on the following two questions: (i) How significant has TFP's role been in post‐reform Chinese growth? (ii) Has TFP growth rate slowed down in more recent years? This paper finds that: (i) the TFP growth rate for mainland China computed using the dual approach also proves high; and (ii) there has been some slowdown in TFP growth rate in recent years.     

The welfare effect of a free trade agreement in the presence of foreign direct investment and rules of origin

This paper investigates the welfare effect of forming a free trade agreement (FTA). To receive tariff‐free treatment, firms must comply with the rules of origin (ROO). Outside firms could undertake either market‐oriented or export‐platform foreign direct investments (FDIs). ROO have the following effects: (i) An infeasible FTA may become feasible by deterring outside firms' FDIs, (ii) an FDI of a less efficient firm could replace that of an efficient firm, or (iii) FDIs made before the FTA is concluded might be eliminated. These potential effects complicate the welfare effect of the FTA and could decrease the consumer surplus.     

Portfolio Optimization under Lower Partial Risk Measures

Portfolio management using lower partial risk (downside risk) measures is attracting more attention of practitioners in recent years. The purpose of this paper is to review important characteristics of these riskmeasures and conduct simulation using four alternative measures, lower semi-variance, lower semi-absolute deviation, first order below targetrisk and conditional value-at-risk.We will show that these risk measures are useful to control downside risk whenthe distribution of assets is non-symmetric. Further, we will propose a computational scheme to resolve the difficultyassociated with solving a large dense linear programming problems resulting from these models. We will demonstrate that this method can in fact solve problems consisting of10⁴ assets and 10⁵ scenarios within a practical amount of CPU time.
