On the consumption insurance effects of long-term care insurance in Japan: Evidence from micro-level household data

Using micro-level household data in the 2001 Comprehensive Survey of the Living Conditions of the People on Health and Welfare compiled by the Japanese Ministry of Health, Labor and Welfare, this paper examines how having a household member in need of long-term nursing care can result in welfare losses measured in terms of consumption. In so doing, this study evaluates the role of the public long-term care insurance scheme implemented in Japan in April 2000. The results indicate that when households include a disabled family member, household consumption net of long-term care costs do not decrease as much as before the introduction of long-term care insurance. Further, when compared with the surveys conducted in 1998, the adverse effects on consumption net of long-term care costs have become much weaker. These findings suggest that the introduction of social insurance in 2000 helped Japanese households to reduce the welfare losses associated with a disabled family member.     

Tourism's contribution to the Yugoslav economy

Tourism is an important sector of the post-industrial economies of the developed nations. This article concentrates on the contribution of tourism to the balance of payments in Yugoslavia. Current methods of assessing the value of tourism transactions are inadequate and make international comparisons impossible. The complexity involved in defining ‘tourism’ has led to the accumulation of meaningless data. The IMF's standard balance-of-payments model is described, and the ways in which Yugoslavia's measurements of tourism income and expenditure could be standardized according to IMF recommendations and thus become use- ful in economic policy formulation.     

Residential Mobility Decisions in Japan: Effects of Housing Equity Constraints and Income Shocks under the Recourse Loan System

This paper draws on six waves of Japanese household longitudinal data (Keio Household Panel Survey, KHPS) and estimates a conditional fixed effects logit model to investigate the effects of housing equity constraints and income shocks on own-to-own residential moves in Japan. By looking at contemporaneous extended Loan-to-Value (ELTV) and extended Debt-to-Income (EDTI) ratios under the recourse loan system, we examine whether housing equity constraints and negative income shocks have any impact on own-to-own residential moves. Taking account of the specific nature of the recourse loan system in Japan, we further investigate whether these effects are different between positive and negative equity households. The estimation results show that housing equity constraints and negative income shocks significantly deter own-to-own residential moves for positive equity households.     

An Algorithm of Recommending Apposite ID Photos

This article proposes an algorithm to recommend apposite ID photos for users by judging the photo of which the facial expression is apposite or not as the ID photo. Microsoft’s Kinect sensor is used for taking photos. Parts of the face, such as eyes, nose, and mouth, are analyzed as explanatory variables for judging face expression. Some body coordinate information such as head and shoulders is used to trim the photos. Neural networks and support vector machines are employed and compared to our proposed method. To achieve accurate results, ten examinees including specialized staff are selected for taking ID photo used for training models. A series of experiments are conducted to examine the validity. As a result, the accuracy of neural networks is better than that of the support vector machine. Furthermore, we analyze and discuss the difference between system results and specialized staffs’ opinions.

     

Information regulation: Do the victims of externalities pay attention?

Individuals living in metropolitan areas are exposed to a large number of industrial risks. Information regulation is a new tool to manage such risks. We ask if large-scale information initiatives directed at the general public can affect individual risk perceptions. The answer is affirmative. Using the publication of the Toxics Release Inventory as a case study, we find a decline in predicted property values when new information on pollution became available, indicating that homebuyers adjusted their risk perceptions upward. The response, however, is limited to sources of toxic emissions that are located at a moderate distance from the properties in our sample.      

Non-Dummy Agents in Pure Exchange Economies

We introduce a very fundamental and important axiom of the non-dummy. This states that each agent can change the outcome of the mechanism at some preference profile, thus guaranteeing every agent the minimum right to affect the social decision. We study the possibility of strategy-proof, efficient and non-dummy mechanisms in pure exchange economies. We provide two new interesting classes of such mechanisms. The results shed light on the structure of strategy-proof and efficient mechanisms, and should promote a complete characterization of those mechanisms in pure exchange economies with three or more agents.     

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.
