Institutional Economics as Theory of Policy Change: Impact of Past Policy Failures on Present Policy

Social scientists have developed several theories for understanding or evaluating policy change over time. Since all costs or benefits are not internalized owing to positive transaction costs, policymaking is always implemented under cost underestimation conditions and, therefore, is imperfect. I call this trait policy failure in this article. Furthermore, I show that a new framework combining the social costs approach and the legal/economic approach in institutional economics is suitable and can be applied to evaluating how past policy failures affect present policy, providing as an example the Fukushima nuclear disaster in Japan.     

Semiparametric Model of Hedonic Housing Prices in Japan

We propose a semiparametric hedonic model of housing prices with nonlinearity in age and cohort effects. The model avoids the simultaneity problem among age, cohort and year effects, which is a common problem in linear hedonic models. Applying the model to housing prices in Tokyo between 1990 and 2008 revealed significant nonlinearities in both the age and cohort effects, and significant interactions between these effects, with the shape of the age effect differing across housing cohorts. Estimates of the year effect indicated a declining trend in prices that was more pronounced compared with those of conventional linear hedonic models.     

The Impact of Regional Factors on the Start‐Up Ratio in Japan*

We analyze regional factors of the start‐up ratio in Japan using two datasets with different regional aggregation levels. The explanatory variables represent demand, cost, human resource, financial, industry agglomeration and industrial structure, and other factors. The empirical results demonstrate that even though all these factors significantly affect the start‐up ratio at the municipality level, some of these factors are not significant at a larger economic area level. In particular, we obtained evidence that human resource factors, together with the average wage and average size of establishments, are important determinants of the regional start‐up ratio in both the samples.     

Welfare variations and the comparative statics of demand

By employing order-theoretic comparative statics, we provide necessary and sufficient conditions on the direct utility function (alternatively, on the indirect utility function) to guarantee that the compensating and equivalent variations are monotonically increasing in income. We also show that these conditions are sufficient to guarantee normal demand. Our results do not depend on the smoothness or strict quasiconcavity of the utility function, and can be extended to a setting with non-linear prices.     

Real exchange rate appreciation,resource boom,and policy reform in Myanmar

Over the six‐year period 2006‐11, the real exchange rate of the Myanmar kyat appreciated 200 per cent, resulting in the value of the US dollar in Myanmar falling to one‐third of its pre‐2006 level. While the resource boom is suspected to be the source of the real exchange rate appreciation, administrative controls on foreign exchange and imports had much more impact. Foreign exchange controls limited the convertibility of the kyat to foreign currencies and spurred negotiated transactions of foreign exchange outside the banking sector, hampering the foreign exchange market interventions of the government and Central Bank. Import controls repressed imports, aggravating excess supplies of foreign exchange. Relaxation of administrative controls is necessary for moderating currency appreciation.     

A model for evaluating extreme risks with stochastic sustainability criteria: a case study of soil remediation on landfill sites

This article addresses the issue of risk management for extreme events. The term stochastic sustainability will be defined in relation to the risk management of extreme events. On the basis of stochastic sustainability, a risk evaluation function is defined as an efficient reserve to remedy contaminations just as a premium rating in insurance policy. A term of generalized safety loading is used as a key concept to evaluate the degree of extremeness of risk. A simple model of the environmental or infrastructure systems is used to illustrate the procedure of risk evaluation where stochastic sustainability is required in case of accidental

environmental contamination. A case study of soil contamination at landfill sites is presented as an example to test this risk evaluation function.     

Trade Gains in Chaotic Equilibria

It is shown by means of an overlapping-generations (OLG) example that free international trade may be both deterministically chaotic and gainful in the sense of Pareto to a participating country.     

The Internationalization of the World Economy and its Implication for National Welfare

There is no generally accepted definition of internationalization or globalization. The present paper offers three alternative definitions, in terms of (i) an enlargement of the set of trading countries, (ii) an enlargement of the set of traded commodities, or (iii) the international sharing of technology. It is shown that if each country adopts a Paretian scheme of internal compensation then internationalization in each sense leaves at least one country better off, and that if international compensation is admitted then internationalization in each sense makes every country better off.     

The influence of indoor air on personal exposure to volatile organic compounds and its risk estimation

This paper summarizes the results of personal exposure monitoring and estimates the risk from exposure to 18 volatile organic compounds compared with health criteria set by the US Environmental Protection Agency. In study 1, personal exposure levels and outdoor air concentrations were compared, and in study 2, personal exposure levels and the corresponding indoor air concentrations were compared. From these studies, it was concluded that personal exposure to volatile organic compounds depended markedly on indoor air quality and that handling of compounds increased personal exposure markedly. Risk estimations indicated that chloroform in tap water, benzene from cigarette smoke and p -dichlorobenzene from household insecticide needed caution.     

School Education,Learning‐by‐Doing,and Fertility in Economic Development

We examine the policy implications of relaxing constraints on the educational choice of individuals for economic development. Distinguishing human capital accumulation through schooling and through learning‐by‐doing and knowledge spillovers, we show that in the earlier stages of development, mitigating and eventually eliminating constraints on school education would be necessary for even further economic development. Expanded school education increases the income of individuals and encourages physical capital accumulation, which enlarges productive knowledge through implementation and operations. The increased labor productivity thus boosts economic growth. In the process, the fertility rate will decline because of the increased education cost per child.
