A multi-division efficiency evaluation of U.S. electric power companies using a weighted slacks-based measure

Prior to the 1990s, the electric power industry was highly regulated across the world. Under a liberalization policy to open markets and to grow competition commenced in the early 1990s, efficient management has become a necessity for companies in this industry. The current study examines the divisional efficiencies of multi-functional, vertically integrated companies seeking to optimize their overall management efficiency. For this purpose, divisional cost data are used as input into a slacks-based measure (SBM) model. This provides divisional efficiency indices based on slacks, as well as one for the larger firm-level management function. Further, given the important role of cost structure, we introduce a modified SBM, named the weighted SBM (WSBM), which directly incorporates division-specific weights into the objective function. Results reveal that the power generation divisions of the companies studied have significant influence on the overall cost, whereas the impact of the other four divisions - transmission, distribution, sales and general administrative - is limited.     

Strategic Interaction Among Local Governments in Japan: An Application to Cultural Expenditure

In the context of limited local government resources, cultural expenditures are often targeted for reduction. In Japan in particular, with its aging population, cultural expenditures have low priority. This paper examines whether or not local governments strategically influence each other with respect to cultural spending, using data from Japanese local governments. By estimating the reaction functions for local cultural expenditures, we find that there exists free‐rider behaviour between local cultural expenditures that produce beneficial spillover effects. We also find a larger free‐rider incentive the shorter the distance between neighbouring regions, the shorter the travel time between neighbouring regions, and the larger the neighbouring region's population. Furthermore, our results reveal that the provision of cultural services through intergovernmental strategic behaviours is more elastic with respect to the relative change of the distance or the travel time among neighbouring regions than to that of the population size among neighbouring regions.     

Local country attributes and the emergence of high tech clusters

The aim of this study is to explore the effect of a country’s attributes on the decision of firms to be active globally. We first built a theoretical model, which shows that an initial difference in the business environment may dampen the desire of firms located in countries with a relatively weak business environment to seek a higher level of R&D. The decision not to pursue higher levels of R&D leads, in turn, to lower output and lower scope of activity of global firms in these countries. Moreover, firms with relatively high level of management skills will choose to migrate from a relatively weak country to one with a stronger business environment, creating a brain drain that will further impoverish the weak country.     

Measuring Search Frictions Using Japanese Microdata

This paper estimates individual‐level matching functions to measure search frictions in the Japanese labour market and presents the determinants of search duration. We employ administrative microdata that track the job search process of job seekers who left or lost their job in August 2005 and subsequently registered at their local public employment service. Our finding is that the matching function exhibits decreasing rather than constant returns‐to‐scale for job seekers and vacancies. We also find that after controlling for the benefits period, job seekers who lost their job involuntarily were more likely than those quitting voluntarily to exit from unemployment.     

Japanese Housing Tenure Choice and Welfare Implications after the Revision of the Tenant Protection Law

A new mode of housing tenure in Japan, rental housing with fixed rental terms, was introduced in March 2000 with the revision of the Japanese Tenant Protection Law. This paper examines the implications of this new system by analyzing the determinants of the choices by households among the three types of housing tenure in Japan: owned housing, general rental housing, and rental housing with fixed rental terms, and calculates the estimated compensating variation. Our micro-data is based on the three waves of Japanese household longitudinal data (Keio Household Panel Survey, KHPS) covering all of Japan. The difference between general rental housing and rental housing with fixed rental terms is reflected in the length of the contract term and the level of rent. We carefully eliminate potential sample selection bias introduced to the conditional logit housing tenure choice model through the estimation of the hedonic price regression of each housing tenure alternative. We find that households with a smaller number of family members, those who moved from outside the local housing market, those headed by an unmarried household head, and those with plans to own a house in the near future tend to select rental housing with fixed rental terms. The estimated mean compensating variation by introducing rental housing with fixed rental terms for all households selecting that tenure is 1,205 JPY per month or 1.96% of their monthly rent. Moreover, younger and/or lower income households derived the greatest benefit from the revised law in the form of lower rents.

Using the Capital Assets Pricing Model for risk management—A tool for multinational corporation managers

In this article, using a theoretical model and empirical analysis, we show how multinational corporations (MNCs) can utilize the fundamentals of the Capital Assets Pricing Model (CAPM) to formulate a strategic risk management in a global economy. We show that MNCs with branches all over the world, specifically those that specialize in nontradable goods (e.g., McDonald's), should consider each country's beta as the appropriate measure of the relevant risk attached to the location in the country. Finally, using data from the most recent world economic crisis (the subprime crisis), we show that during a world economic crisis the loss of growth will be significantly higher in countries with higher betas, and lower in those with lower betas. © 2011 Wiley Periodicals, Inc.     

Decomposition of cost efficiency and its application to Japanese-US electric utility comparisons

This paper presents a new formula for decomposing cost efficiency into technical, price, and allocative efficiencies in an environment marked by the fact that unit input prices differ among certain enterprises. We employed this formula in comparing cost efficiency between Japanese and US electric power companies, and found a significant difference in the price-based efficiency. However, negligible differences were found in the technical and allocative efficiencies.     

Earthquake risk and housing prices in Japan: Evidence before and after massive earthquakes

The hedonic pricing approach is used to examine whether homeowners and/or renters alter their subjective assessments of earthquake risks after massive earthquakes. Using nation-wide household panel data coupled with earthquake hazard information and records of observed earthquakes, we find that there are some modifications of individuals' assessments of earthquake risk in both cases. We have carefully taken into consideration the bias stemming from the use of objective risk variables as a proxy for individual risk assessments. Our results suggest that the price discount from locating within a quake-prone area is significantly larger soon after earthquake events than beforehand. We argue that the most likely interpretation for this result is that households tend to underestimate earthquake risk if there has not been a recent occurrence.     

Effects of subsidized home loans on housing decisions and efficiency in Japan: Tradeoff between quality and quantity

First, we will present a microeconomic model of Japanese housing demand based on the Japanese home financing system. The focus of the model will be on the tradeoff between housing quality and quantity. We will derive the owner-occupied housing user cost of capital for several different subsamples. The unique feature of the model is the use of nonlinear budget constraints. Next, we will try reduced form estimation based on a composite housing demand model and a characteristic housing demand model. Estimation results indicate that those who do not receive funds from the JHCL are more price-elastic and more income-elastic for composite housing demand and floor demand. Recipients of JHLC funds have more price-elastic demand for quality as they compensate for institutional constraints on their selection of floor space. Finally, we will estimate the effect on housing demand if JHLC loan interest rates are not classified by the size of a house but are adjusted to the private loan rate and if the JHLC lends funds based on the market value of the house. We will also calculate the excess burden for each household created by the present JHLC home financing policy. Households distort their housing consumption by overconsuming quantity and underconsuming quality.
