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.     

Development of educational program for production manager leading new perspectives on manufacturing technology

In this paper, we consider the problems associated with the development and management of an educational program for manufacturing managers in leadership roles who are making contributions towards the creation of customer delight as well as customer satisfaction using manufacturing technology. The basic concept combines an intelligent knowledge-based approach with the kaizen activity program within the framework of value creation and comparative advantage models based on a network referred to as Academia, Business, Consultancy, and Government (ABC-G). This educational program, which reflects the characteristics of manufacturing technologies and practices in the Hokuriku District of Japan, was developed in 2005–2006 and the trial education was developed in 2005 and 2006, and a trial run of this program was conducted in 2006 and 2007 in close collaboration with local manufacturing companies and their employees. The results are informative of the effects of educating manufacturing managers in Japan and the problems that will have to be overcome for the continuous improvement of the program.     

Market Size and Firm Location in a Service Industry

This paper investigates the welfare effects of firm location in a service industry. We consider the situation where firms determine their locations in either of two regions with a difference in market size. From the viewpoint of the consumers' welfare, there are too few firms in the large market and too many in the small market. However, from the viewpoint of the producers' and social welfare, the opposite is true. Further, an increase in the difference in market size is unambiguously unfavorable for the producers. On the other hand, such an increase is favorable for the consumers and the economy as a whole.     

Long-run matching relationship in the Japanese labor market

This paper investigates the long-run relationship among new hiring, unemployment (job seekers), and unfilled vacancies in Japan, using an annual panel data on 47 prefectures for 1972-1999. We find that these three variables are I(1) processes, and are cointegrated in our panel data. Further, we estimate the panel cointegration equation derived from a Cobb-Douglas matching function by the heterogeneous fully modified OLS and heterogeneous dynamic OLS. The estimation results reveal that conventional within estimates could have non-negligible biases.First version received: November 2002/Final version received: October 2003All correspondence to Shigeki Kano.

Identifying the sources of energy use change: Multiple calibration decomposition analysis and structural decomposition analysis

Decomposition methodologies are requisite to identify the sources of changes in energy use or carbon dioxide emissions. This paper is an inquiry into the theoretical properties of such decomposition methodologies. The study first presents our new decomposition methodology – the Multiple Calibration Decomposition Analysis (MCDA) – as a tool for the investigation. Then, it theoretically reexamines an established decomposition methodology – the Structural Decomposition Analysis proposed by Casler and Rose (1998). Subsequently, the study empirically investigates the properties of both methodologies, applying them to an actual case: the changes in energy use and carbon dioxide emissions in Japan during the oil crises period, when the oil price had a significant influence on the economy. The result shows that understanding the theoretical properties of decomposition methodologies is essential for a precise interpretation of empirical results.     

Collateral secured loans in a monetary economy

This paper presents a microfounded model of money where durable assets serve as a guarantee to repay consumption loans. We study a steady state equilibrium where money and credit coexist. In such an equilibrium, a larger investment in durable capital relaxes the borrowing constraint faced by consumers. We show that the occurrence of over-investment and the behavior of capital accumulation depend on the rate of inflation, the relative risk aversion of agents and the marginal productivity of the capital goods.     

Endogenous Timing in a Strategic Trade Policy Game: A Two-Country Oligopoly Model with Multiple Firms

This paper examines strategic trade policy games where the number of firms in the importing and exporting countries differs and all firms play as Cournot oligopolies. Under the assumption of linear demand and constant marginal cost, we show that, if the number of firms in the exporting country exceeds that in the importing country by more than three, the government of the exporting country chooses to move as a leader, imposing an export tax on firms. The government of the importing country then becomes a follower and imposes an import tariff. This lies contrary to the previous study, which assumed that there is only one firm in each country.     

Trade and Gains from Trade Between Profit-maximizing and Labour-managed Countries with Imperfect Competition

This paper offers a theoretical analysis of trade and the gains from trade in general equilibrium under imperfect competition by assuming that all firms in one country are of the labour-managed type (maximizing the income of labour) while those in the other country are of the profit-maximizing type. Our main conclusion is that if the labour-managed country is larger than or equal to the profit-maximizing country, the profit-maximizing country exports the imperfectly competitive commodity and gains from trade while the labour-managed country exports the perfectly competitive commodity and may lose from trade.     

Managers’ exploration activities and individual unlearning: the mediating role of learning orientation and reflection

Abstract

The main goal of this study was to investigate the effects of managers’ exploration activities on learning orientation, reflection, and unlearning of team members. A questionnaire survey was conducted among 115 employees in 23 teams from a Japanese pharmaceutical company. The results of multi-level analyses suggest that managers’ exploration activities had a direct influence on team members’ learning orientations, which subsequently had a positive influence on their unlearning, with and without the mediation of reflection. These findings suggest that a subordinate’s unlearning is driven by managers’ activities through motivational and cognitive processes. The theoretical and practical implications of the findings are discussed.     

Modeling Methods for Discrete Choice Analysis

This paper introduces new forms, sampling and estimation approaches fordiscrete choice models. The new models include behavioral specifications oflatent class choice models, multinomial probit, hybrid logit, andnon-parametric methods. Recent contributions also include new specializedchoice based sample designs that permit greater efficiency in datacollection. Finally, the paper describes recent developments in the use ofsimulation methods for model estimation. These developments are designed toallow the applications of discrete choice models to a wider variety ofdiscrete choice problems.
