Experiments on risk attitude: The case of Chinese students

This paper examines Chinese students' risk attitudes using selling and buying experiments with lotteries. We found that subjects were more risk averse during the buying experiment than during the selling experiment, suggesting an endowment effect. In the selling experiment, subjects were risk loving when there was a low win probability and risk averse with a high win probability, whereas they were risk averse in the buying experiment. Using the prize money won during the experiment as a measure of wealth, we found decreasing absolute risk aversion. Subjects' risk attitudes as revealed in the experiments explain their risky asset holding behavior.     

WHO SUPPORTS REDISTRIBUTION?*

Using an original data set, we investigated the determinants of individual preferences over income redistribution in Japan. Although income level is negatively correlated with support for redistribution, it does not explain much; there are other important factors that relate to dynamics and uncertainty, such as income risk. Even after controlling for income, both risk‐averse individuals and those who expect to be unemployed in the future favour greater redistribution. Interaction of ageing and mobility prove important. The relatively poor elderly, who presumably have few prospects of upward mobility, strongly support greater redistribution, whereas younger people are less sympathetic to such a policy.     

Trade, Vertical Production Chain, and Competition Policy

The authors build a trade model that renders tractable the process in which imperfect competition in a country's downstream sector affects the rest of the world through international trade. For this purpose, internationally traded goods are viewed as middle products in the vertical chain of production, in which middle products are produced upstream and transformed into final consumption goods downstream. Suppression of competition in a country's downstream sector may serve as a beggar-thy-neighbor policy, increasing that country's own utility while reducing that of its trading partner countries.     

Life cycle and bequest savings A study of Japanese and U.S. households based on data from the 1984 NSFIE and the 1983 survey of consumer finances

This paper investigates whether the elderly save or dissave in light of two newly available sets of cross-section micro data, the 1983 “Survey of Consumer Finance” for the United States and the 1984 “National Survey of Family Income and Expenditure” for Japan. Contrary to dominant earlier findings we find for the United States that families after retirement dissave on average about a third of their peak wealth by the time of death, leaving the rest (mostly their homes) as bequests. For Japan, special handling is made to eliminate possible sample selection bias due to the different economic characteristics of the elderly forming independent households and those living with children. We find that the elderly belonging to both groups continue to save, and moreover, there appear to be significant signs of ongoing wealth transfer between the generations. The data in both countries also show that the elasticity of saving with respect to a life time income measure is significantly greater than unity, and more strongly so within higher age groups. J.

Human Capital Accumulation In the Middle-Income Country and World Trade*

I construct a dynamic three-country model of trade and growth in which a worker determines how long he takes training. the path of human capital accumulation of a worker is analyzed. I consider the case in which per capita human capital grows in the middle-income country while it stagnates in the high-income and low-income countries. Effects of the middle-income country's growth are studied.     

Using Constraint Programming to Design an Option-based Decision Support System

Financial options and futures give investors the opportunity to form complex strategies that meet their investment objectives for risk management. However, this opportunity gives rise to a difficult task: finding a desired strategy from among a large number of possible strategies. This paper describes an intelligent decision-support system for generating option-based investment strategies by using constraint programming, which is an integrated framework of Artificial Intelligence and Logic Programming. In this system, constraint programming acts as a bridge between qualitative and quantitative analyses in decision processes. In qualitative analysis, logical reasoning with hypotheses is used to automatically create complex strategies through abstract matching with investors' profiles. Here, abstract matching can be regarded as symbolic computation for producing qualitatively reasonable strategies. In quantitative analysis, a set of complete solutions that satisfy user-supplied constraints are obtained by constraint satisfaction and optimization. A constraint language based on the framework of Constraint Logic Programming has been developed in order to integrate these symbolic and numerical computations in a uniform way. The resulting system written in this language has the following features. (1) Unlike rule-based expert systems, the constraint-based system can create novel investment strategies. (2) A smooth transition from qualitative to quantitative analyses can be naturally achieved due to the constraint language. (3) Qualitative analysis can reduce search complexity, because the analysis focuses on a small set of qualitative distinctions in solution space. These features indicate the usefulness of constraint programming for designing intelligent decision-support systems.     

Relative Income Position and Happiness: Are Cabinet Supporters Different from Others in Japan?

During the period of 2001–2006, the Liberal Democratic Party (LDP) adopted a market‐oriented policy under the Koizumi cabinet. Using data covering the Koizumi and first Abe cabinets, the present paper attempts to examine whether the effects of relative income differ between supporters and non‐supporters of the Koizumi cabinet. Key findings are as follows: within the Koizumi cabinet period, a relatively low‐income position is negatively related to happiness for non‐LDP supporters but not for LDP supporters. However, under the period of the first Abe cabinet, the difference in the effect of relative income for LDP supporters and others disappears. These results imply that an expectation of market outcomes leads to a difference in the effect of relative income position on happiness levels.     

Quality of Labor Markets in a Developing Country

This study is an application of Yano's market quality economics to trade. It considers the quality of labor markets in a developing country and sheds light on an important role of the voting mechanism in the process of which the quality of labor markets is endogenously determined. Assuming the majority vote, it is demonstrated that if the timing of voting is wrong, a developing country misses high‐quality labor markets although trade provides an opportunity for it to reach such markets.     

Supermodularity and Global Supply Chains without the South

We investigate why the South is hardly involved in the global supply chain for the Boeing 787. We demonstrate that if the production process is supermodular, the South is excluded from global supply chains.     

The Impact of Differential Falls in Offshoring Costs on Welfare

We highlight the fact that offshoring firms and local firms that do not offshore coexist in the North. Adopting the O‐ring production function approach to offshoring, we demonstrate that a fall in offshoring costs in any sector makes the South better off and that if offshoring costs in a high‐technology sector fall at a faster rate, the North is worse off, and vice versa.
