The Moderating Effects of Political Skill and Leader–Member Exchange on the Relationship Between Organizational Politics and Affective Commitment

Previous empirical studies have shown that perceptions of organizational politics are negatively related to individuals’ affective commitment. The key contribution of this study was that it found the interactive moderating effects of political skill and quality of leader–member exchange (LMX) on the relationship between perceptions of organizational politics and affective commitment. Our results indicated that politics perception affective commitment relationship was weaker when both political skill and quality of LMX are high. When only political skill is high and the quality of LMX is low, or LMX quality is high but political skill is low, the negative relationship between politics perception and affective commitment was not mitigated. Limitations and implications for future research are discussed.     

Optimal Mortgage Refinancing with Regime Switches

A model of rational mortgage refinancing is developed where the drift and volatility of interest rate process switch between two regimes. Because of the possibility of a regime shift, the optimal refinancing policy is characterized by the different threshold of interest differential for each regime. Numerical simulation demonstrates that the optimal refinancing threshold in each regime can be smaller or larger than the threshold under single-regime models. Finally, we evaluate the predictions of the model, based on the estimated parameters for a two-regime model to capture the evolution of the mortgage rates in the US. Our model can produce both late and early refinancing, which is consistent with the observed refinancing behavior.

Social value of public information re-examined

As an extension of Hirshleifer's horse race example into a competitive exchange market framework, this paper quantitatively re-examines the condition under which social value of public information can be positive. For a prototype economy of two risk averse traders, we prove that their discordance of beliefs makes the social value of a certain class of inconclusive information either positive or negative depending on whether their endowments are or are not predominantly associated with states they regard as more probable, whereas it has been known that information acquisition is always socially wasteful under concordant beliefs.     

Sectoral Price Movements under the Yen Appreciation

This paper analyzes the movements of tradable goods prices in Japan. The import price indices and the export price indices are matched with the domestic wholesale price indices at the most detailed level available for Japan, and the pricing behavior in the yen appreciation period (1985–1995) is examined. In the import-side analysis, we investigate how far the price movements under currency appreciation deviate from the law of one price. We find that internal–external price differentials have surprisingly expanded for most of the products since 1985. For a number of commodities, the import prices do not decline as far as the exchange rate appreciates, and the domestic wholesale prices do not decrease as far as the import prices decline. Although the expanded price gaps cannot necessarily be interpreted as a result of deliberate trade barriers, they suggest that some sort of handicap is imposed on imported goods and the large fraction of rent generated by the yen appreciation is intercepted in the middle. In the export-side analysis, the relationship between the globalization of firms' activities and export pass-through is investigated. Our cross-sectional regression analysis indicates that the export path-through rates tend to be low when the value added ratios of foreign production of Japanese firms are high. Low export pass-through under currency appreciation is often interpreted as a result of firms' attempts to keep their foreign market share, but the globalization of firms' activities may be another important factor in lowering the pass-through.J.

Forecasting Japanese health futures with the BFT : A demand-side approach

In response to the problems associated with supply-side health-care planning, the Institute of Health Systems Development has created a demand-side approach which has been named BFT (Bioforecasting Technology). The system involves integration of data regarding the population, the natural and social environment, and the health/medical/social services with projections on factors that will influence the future population's demand for different kinds of health services. BFT forecasts have proved highly accurate. The system has been used throughout Japan and internationally, and much wider applications beyond standard hospital and health planning are possible.     

A comparison of the Box-Cox maximum likelihood estimator and the non-linear two-stage least squares estimator

This paper investigates the limiting behaviour of the ‘maximum likelihood estimator’(MLE) based on normality, as well as the nonlinear two-stage least squares estimator (NL2S), for the i.i.d. and regression models in which the Box-Cox transformation is applied to the dependent variable. Since the transformed variable cannot in general be normally distributed, the untransformed variable is assumed to have a two-parameter gamma distribution. Tables of probability limits and asymptotic variance demonstrate that, in this case, the inconsistency of the ‘normal MLE’ is often quite pronounced, while the NL2S is consistent and typically well behaved.     

The nonlinear limited-information maximum- likelihood estimator and the modified nonlinear two-stage least-squares estimator

Several limited-information type estimators of the nonlinear simultaneous equation model are considered and their asymptotic covariance matrices are compared. Amemiya (1974) proposed the general class of nonlinear two-stage least-squares estimators. In this paper, its two specific members are considered and, in addition, the nonlinear limited-information maximum- likelihood estimator and the modified nonlinear two-stage least-squares estimator are proposed. Both are shown to be asymptotically more efficient than the nonlinear two-stage least-squares estimator, and the second has the advantage of being computationally simple.     

Internalization of externalities and local government consolidation: empirical evidence from Japan

The fact that jurisdictional consolidation overcomes externality problems in the provision of local public goods is one of the best-known benefits of consolidation in the theoretical literature. Nevertheless, previous studies provide little evidence of how public service spillover effects influence consolidation decisions. This study empirically tests the hypothesis that spillovers induce consolidation, using voting data on the consolidation of Japanese municipalities. The extent of spillovers is measured by estimating the demand function for public goods with externalities. It is found that residents of the municipalities that can internalize a large amount of public goods spillovers through municipal consolidation tend to favor consolidation. This result supports the theoretical inference that spillovers in local public goods affect utility gains from jurisdiction integration, thus serving as one of the key impetuses for boundary reform. Moreover, after controlling for the spillover effects, economies of scale, population share, differences in median income, and unconditional grants can help explain consolidation preference.     

Pandemic (COVID‐19) Policy,Regional Cooperation and the Emerging Global Production Network†

In this paper, we explore the possible policy responses to the COVID‐19 pandemic shock as well as the related economic (financial crisis) shocks on trade and global value chains (GVC) in East Asia. We find that regional policy coordination is critical to mitigate and isolate the pandemic shock. It is important to identify the pandemic events early to flatten the pandemic curve at the national and regional level. This supports a recent study by the World Bank (2020), which highlights the importance of early mitigation policies during the pandemic shock. The cost of the pandemic and economic shocks will increase significantly when several countries in the region experience the pandemic shock concurrently. In this case, flattening the regional pandemic curve becomes important. The results also indicate the need for greater coordination in East Asia to mitigate the pending economic shock in terms of unemployment, corporate bankruptcy and financial market fragility. The paper also highlights that the stability of the GVC network is critical during the pandemic in terms of hedging the risk of disruptions to the procurement of critical medical and health products as well as maintaining service linkages to manufacturing, such as the logistics sector. Regional policy coordination and the stability of GVC will be valuable in the post‐pandemic recovery of the region.
