Fluctuations in Unemployment and Industry Labor Markets

Throughout the 1990s, and particularly in the mid- to late-1990s, the Japanese employment situation went from bad to worse. We investigate the causes of rising unemployment in Japan, using data on individual workers from the “Special Survey of the Labor Force” between 1988 and 1999. This research focuses on the effect of labor market segmentation by industry on labor flows. Our findings reveal that unemployment in the construction industry and, more recently, in the service industry has contributed greatly to the national unemployment rate. We also find that most successful job transfers occur within the same industry, even though workers may experience some periods of unemployment. Finally, our results show that labor market conditions in each industry affect the probability that a worker will fall into unemployment as well as the probability that an unemployed worker will find new employment. These findings suggest that the Japanese labor market is segmented by industry and this segmentation contributed to the worsening unemployment in Japan. J. Japan. Int.

Influence of ADB Bond Issues and US Bonds on Asian Government Bonds*

This article examines whether there is a correlation between the government bond markets of Asian countries and those of the USA, and whether the efforts of international organizations to improve bond markets have had any effect in East Asia. Because the sizes of the government bond markets are larger than those of the corporate bond markets in East Asia, the present paper uses the daily data of government bonds to examine two questions: whether government bond yields in Hong Kong, Singapore and Thailand correlate with US government bond yields, and whether bonds in these Asian countries are influenced by ADB bond issues. The present study analyzes these issues by demonstrating the fluctuations in bond yields and carrying out an estimation using the exponential generalized autoregressive conditional heteroskedasticity model. The results substantiate that there is indeed a correlation between Asian and US bond markets, and that ADB bond issuance in local markets can contribute to the development of Asian bond markets.     

Influence of real estate prices on domestic bank loans in Southeast Asia

This study examines whether and how fluctuations in real estate prices affected bank lending in Malaysia, Singapore, and Thailand before and after the 1997–98 Asian financial crisis. Since the crisis, it has been claimed that the rise and fall in the price of real estate, which is used as collateral, affected bank lending and the macroeconomy in these Southeast Asian countries. The study implements a dynamic model of bank lending and employs a test using the panel data of domestic bank balance sheets in order to estimate the influence of real estate prices on new bank lending in the three countries. The study also examines the conditions surrounding the role of real estate as collateral for bank loans in the countries. The regression results suggest that fluctuations in real estate prices can influence domestic bank lending and did so, especially after the crisis in Singapore and Thailand, and that domestic bank lending behaviour in these countries changed after the crisis.     

Voluntarily separable repeated Prisonerʼs Dilemma with reference letters

We consider the voluntarily separable repeated Prisoner?s Dilemma model in which players randomly meet and form pairs to repeatedly play Prisoner?s Dilemma only by mutual agreement. While the literature has dealt with the case of no information flow across partnerships, we consider the case in which players can issue a “reference letter” to verify at least that the partnership entered the cooperation phase. We show that such reference letters can be voluntarily provided by the partners even at some cost, and that the sheer existence of a letter shortens the trust-building periods and thus improves social efficiency.     

Belief-Based Refinements in Signalling Games

There are many economic problems which, when modelled as games of incomplete information, give rise to many sequential equilibria, severely limiting the usefulness of the model. There has recently been a large literature devoted to "refining" the set of equilibria in order to reduce this multiplicity by restricting the set of admissible disequilibrium beliefs. This paper argues that the logical foundations of some refinements and the equilibria they focus on are problematic and, further, proposes an alternative refinement that avoids the difficulties. We also provide an existence theorem covering a broad class of signalling games often studied in economics. Journal of Economic Literature Classification Numbers: C72, C70, D82.     

Effects of a short-stay vacation on the mental health of Japanese employees*

Many studies have focused on the effects of tourism on mental health. This study revealed that short-stay vacations at mental health rejuvenation facilities could reduce Japanese employees’ stress levels. We conducted two studies with two groups of participants (N?=?34 and 26, respectively), in order to obtain both objective and subjective evaluations. The results suggested that taking a short-stay vacation at a mental health rejuvenation facility was effective for helping employees to maintain good mental health, and that stress reduction was particularly evident in the highly stressed group. Practical and theoretical implications are discussed with a view to providing suggestions for addressing work-related stress in Japanese employees.
