IFRS Adoption and Accounting Conservatism of Japanese Firms with Governance System Transition

Accounting for Heterogeneity in Network Formation Behaviour: An Application to Vietnamese SMEs

Network formation is often characterized by homophily, i.e. the tendency of agents to connect with others who have similar attributes. However, while most agents are homophilous, others could be heterophilous; they aim to create ties with dissimilar agents. This study provides empirical evidence supporting this hypothesis by applying a random coefficient approach to data on the information-sharing networks of small- and medium-sized Vietnamese enterprises. In particular, we find that firms tend to form heterophilous links with respect to business type and gender ratio. One possible reason for the heterophily is that firms can obtain useful and performance-improving information from such dissimilar partners.     

Forest sustainability and trade policies

Many analyses of trade and environment have concluded that trade liberalization is Pareto improvement with Pigovian tax systems even when production and consumption processes bring non-market externalities. But in case of global forest issue there are many accusations that the trade liberalization of forest products has caused the degradation of forest sustainability. In this paper we try to explain the gap between the theory and the real situation from theoretical point of view. We will analyze comprehensively about free trade and forest sustainability by partial and general equilibrium analyses. Pigovian systems work well under the assumption of complete substitutivity of consumption between external effects and marketable commodities. If it were not satisfied, it is inevitable to levy import tariff or to take some domestic price support systems to guide the production point into sustainable forests.     

Are ASEAN Countries Havens for Japanese Pollution‐Intensive Industry?

In an era of closer worldwide economic integration, the role that environmental regulations play in shaping a country's comparative advantage is greater than ever. This has led to fears that ‘dirty’ firms will relocate from developed to developing countries where environmental regulations may be less stringent – the so‐called pollution haven hypothesis. To date, however, there is little support for the existence of pollution havens despite anecdotal evidence and the theoretical predictions. In this paper we employ a unique industry‐level dataset for Japan and examine whether Japanese industries have relocated production to their ASEAN neighbours in response to the relative stringency of Japanese environmental regulations. Not only do we find no evidence for pollution‐haven‐consistent behaviour but also some indication that the complex relationship between the characteristics of Japanese dirty industries and environmental regulations may actually have reduced Japanese outward FDI to the Philippines.     

Estimation of risk contributions with MCMC

Determining risk contributions of unit exposures to portfolio-wide economic capital is an important task in financial risk management. Computing risk contributions involves difficulties caused by rare-event simulations. In this study, we address the problem of estimating risk contributions when the total risk is measured by value-at-risk (VaR). Our proposed estimator of VaR contributions is based on the Metropolis-Hasting (MH) algorithm, which is one of the most prevalent Markov chain Monte Carlo (MCMC) methods. Unlike existing estimators, our MH-based estimator consists of samples from the conditional loss distribution given a rare event of interest. This feature enhances sample efficiency compared with the crude Monte Carlo method. Moreover, our method has consistency and asymptotic normality, and is widely applicable to various risk models having a joint loss density. Our numerical experiments based on simulation and real-world data demonstrate that in various risk models, even those having high-dimensional (≈500) inhomogeneous margins, our MH estimator has smaller bias and mean squared error when compared with existing estimators.     

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.
