Market behavior and the types of production functions

The paper presents a unified approach to theory and estimation of production functions based on a simple observation that any production function has a unique representation of its isoquants in terms of the differential equation which may be observable in market. Expressing the marginal rate of substitution between two inputs as the differential equation in these two inputs, various classes of production functions are obtained by integrating this differential equation. Not only does this general approach yield a systematic framework for all known forms but it also generates new types of production functions. Empirical application is also indicated.     

Fiscal Externalities and Efficient Transfers in a Federation

This paper investigates properties of the second best allocation in a fiscal federal system in which both federal tax and intergovernmental grants are involved and the taxation is distortionary. Also, optimal federal grants and tax policies in a decentralized fiscal system are examined. Our major findings are: (i) the second best does not require the equalization of marginal cost of public funds across regions in a conventional form; (ii) matching grants based on either the local tax rates or tax revenues should be introduced to internalize the tax externality; and (iii) once lump-sum and matching grants are optimized, federal tax policy becomes redundant so the optimal fiscal gap is indeterminate.

A simple dynamic decentralized leadership model with private savings and local borrowing regulation

This paper considers a simple dynamic decentralized leadership model with local borrowing and regional productivity-enhancing investment. In this model, the central government is benevolent but cannot commit to ex post intergovernmental transfer policies, while local governments act strategically after accounting for the ex post motives of the central government. We then investigate inefficiency in the subgame perfect equilibrium. We analyze the effect of central control on local borrowing and show that central control is of no benefit because ex ante local taxation works to offset it. We find the model yields different policy implications that central control is effective when extended to the case of residential mobility.     

The Psychology of Impulse Buying: An Integrative Self-Regulation Approach

Impulsive buying grossly violates the assumptions of homo economicus. A variety of perspectives on impulse buying are presented, which have been put forward in consumer, economic, social, and clinical psychology. These include heuristic information processing, time-inconsistent preferences, personality traits and values, self-identity, emotions, conscious self-control, and compulsive buying. These perspectives may sometimes lead to contradictory or paradoxical findings. For instance, impulse buying is often associated with joy and pleasure but has also been found related to negative emotions and low self-esteem. Our argument is that impulsive buying can be understood in terms of psychological functioning, in particular as a form of self-regulation. Regulatory focus theory is then used to bring the various perspectives together by classifying each as a promotion focus strategy (e.g., seeking pleasure) or a prevention focus strategy (e.g., avoiding feelings of low self-esteem). Finally, the question is discussed whether consumers can and should be protected against impulsivity. Our assertion is that regulation against misleading practices that play on the vulnerabilities of impulsive buyers could be sharpened and that information provision to consumers and retailers aimed at strengthening consumers’ self-regulatory capacities may mitigate adverse consequences of impulse buying.     

中国农村收入增长:1990-2002年

本文考察了1990年至2002年间决定中国农村收入增长差异的经济和非经济因素.通过估计收入增长方程,我们首先证实了初始人力资本水平和基础设施状况有显著的正效应.其次,由村层面的社会关系稳定程度度量的社会资本也是一个显著促进收入增长的因素.本文发现的政策含义是:促进农村地区社会稳定的公共政策需要加强,同时也要增加对农村地区,尤其是低收入地区的教育和基础设施建设上的财政支持.     

'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.     

Factors determining residents’ preparedness for floods in modern megalopolises: the case of the Tokai flood disaster in Japan

This study examines how flood risk perception and home ownership affect residents’ preparedness for floods, focusing specifically on the case of the Tokai flood disaster in Nagoya City, one of Japan’s biggest metropolises, in 2000. The greatest rainfall ever recorded in Nagoya City (566.5 mm) occurred on 11–12 September 2000; as a result, a local river burst its banks and flooded the city. A survey was conducted of residents of the affected area in Nagoya City and its adjacent region. The respondents were asked to rate the extent of their experience with, anticipation of, and preparedness for floods before and after the Tokai disaster in terms of taking special measures against floods. The results showed that the degree of preparedness for floods was determined by the level of fear of floods and the amount of damage sustained during the Tokai flood, especially for homeowners. However, the residents’ preparedness did not depend on their anticipation of floods. These findings show that preparedness for floods depends on ownership of a home, fear of flooding, and the amount of damage from previous floods rather than on previous experience with and anticipation of floods.
