Remedying Illegal Actions of Judgment Proof Injurers Via Contracts,Fines and Sanctions

This paper studies the impact of the judgment proof problem on the design of incentives to prevent illegal behavior when the principal delegates a risky production activity to the agent in the presence of moral hazard and adverse selection. The agent can reduce costs by engaging in an illegal action that generates liability. When insolvency is endogenously determined, the principal neither provides incentives to the agent to induce a fully legal action nor designs a contract that makes either party insolvent. The social optimum can be achieved by a fine or non‐monetary sanction. If the fine cannot correct inefficiency, non‐monetary sanction achieves the social optimum by the fully legal action.

Measuring DEA efficiency in cable television network facilities: what are appropriate criteria for determining the amounts of governmental subsidies?

Recent technological developments have transformed the cable television industry (CATV) from a simple re-transmitter of terrestrial broadcasting to a provider of a broader-band information infrastructure. With cable operators facing an undesirable market situation while operating a fiber optics network vital to the creation of an information-based society within Japan, the Japanese Government has introduced several supportive measures for the industry. Such governmental intervention should desirably be justified not only from a political viewpoint but also from an economic one; otherwise such measures may distort economic efficiency. In this article, using Data Envelopment Analysis (DEA), the authors identify the deficiencies of an accounting-based intervention scheme and propose an alternative framework with no disincentive side effects.     

A cross-country comparison of interindustry linkages and the role of imported intermediate inputs

This paper compares the patterns of intermediate input use, the levels of overall and domestic industrial linkages, and the role of imported intermediate goods in production among nine countries and over time, based on input-output data. Evidence on distinct differences in overall interindustry linkages and import contents between Korea and Taiwan on the one hand and Turkey, Colombia, and Mexico on the other are presented. The differences are then related to the differences in export structure and in trade and industrial policies adopted in each country.     

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.     

Using DEA to evaluate the state of society as measured by multiple social indicators

This paper presents an approach for discussing the state of society, which is measured by multiple social indicators, using data envelopment analysis (DEA). Replacing inputs and outputs in DEA with negative and positive social indicators respectively, we analyze the desirability of living in the 47 prefectures of Japan. This is also a proposal for the potential use of DEA in multi-dimensional evaluation analysis other than the standard DEA efficiency analysis. The results using eight social indicators identify 26 DEA desirable prefectures out of the 47 and present other useful knowledge and information. It is concluded that DEA, which can avoid uniform evaluation by an a priori weighting system, provides availability as a comprehensive evaluation tool different from traditional ones.     

Convenience yield and the theory of storage: applying an option‐based approach

We propose that an options‐based approach is a superior alternative to the traditional cost‐of‐carry method to model both the behaviour of convenience yields and the commodity price responses to changes in inventory levels. This approach is shown to be more robust and avoids the simplifying assumptions embedded in cost‐of‐carry valuation which fully accounts for the non‐negativity constraint on inventory. Unlike the cost‐of‐carry approach, the options‐based approach does not treat the convenience yield as an exogenous factor. This offers a more natural measure of implied convenience yields in commodity trading strategies. We test the relationship between convenience yields and inventory levels for a number of liquidly traded base metals using both methods. Our results show that the relationship between convenience yields and inventory levels is strongly defined under the options‐based approach in line with market beliefs. This result is consistent with other studies that have used the options‐based approach in other nonmetals commodity markets.     

A new approach to estimate concentrations of alcohol ethoxylate in rivers in Japan for screening-level risk assessment

Alcohol ethoxylate (AE) is a widely used household detergent that is ubiquitous in aquatic environments. To assess and manage the risk of AE, its environmental exposure concentrations must be evaluated in rivers nationwide; however, very few AE monitoring data are currently available. Furthermore, developing a rigorous exposure model that would cover rivers nationwide would require a great deal of time, human resources, and money. We developed a new approach to estimate AE concentrations in rivers throughout Japan for screening-level risk assessment. In this approach, five-day biochemical oxygen demand (BOD₅) data were used as a surrogate indicator of the AE concentration in river water. The Tama and Nikko Rivers were ranked according to their BOD₅ data, and the AE concentrations of the Nikko River were then estimated using the Standardized Hydrology-based Assessment tool for chemical Exposure Load (AIST-SHANEL) model. For each river, the concentrations of AE in its waters were projected based on that river’s reported BOD₅ values, its ranking, the approximation formula for AE and BOD₅, and estimated AE concentrations in water of the Nikko River from the model. The accuracy of the projected values was validated by comparing the projected AE concentrations in water from the Tama River with its monitoring data. There are various technical uncertainties associated with this approach; however, our results suggest that this new approach can be applied in screening-level exposure assessment of other chemical substances that have properties similar to AE.     

Relationship between environmental performance and financial performance: an empirical analysis of japanese corporations

The hypotheses that a firm's environmental performance has a positive impact on its financial performance and vice versa are statistically supported by Japanese data. However, this tendency for two‐way positive interaction appears to be only a relatively recent phenomenon. The tendency for realizing the two‐way interaction is not limited to the top‐scoring firms in terms of both financial and environmental performance. On the contrary, this is also a trend that can be observed fairly generally. Obviously, when we consider only scores of those companies that published the relevant information in their environmental reports, and conduct the statistical causality test with such information as additional input to the pooled time‐series and cross‐section data of financial performance, the results become more strongly significant. From the recent experience of environmental policies in Japan, we infer that information‐based environmental policy measures are effective to encourage the ongoing transition toward a more sustainable market economy.
