The effects of the raising-the-official-pension-age policy in an overlapping generations economy

This paper studies how economic variables are affected by raising the official pension age. Although it is said that such a policy increases output, this paper shows that such a statement is not necessarily true. Moreover, the paper finds that the social security benefit can decrease, which implies that it might be impossible to sustain the same level of benefit only by such a policy.     

Municipal consolidation and local government behavior: evidence from Japanese voting data on merger referenda

The empirical literature investigating the role of key features of local governments regarding decisions on consolidation tends to use a dummy dependent variable that takes 1 if both adjacent local governments decide to merge and 0 if one of them does not approve consolidation. Under this estimation method, however, it is difficult to know which governments refused to consolidate, as consolidation was not realized. The current study empirically tests the effects of economies of scale, population size, heterogeneity of preferences, and financial factors on municipal preferences for consolidation. It uses voting data from Japanese local referenda to identify preferences of specific individual municipalities, thus allowing a richer examination of local government behavior. The results obtained herein are as follows. Municipalities that could enjoy large economies of scale from consolidation prefer consolidation, while large and small municipalities are likely to merge. Moreover, municipalities receiving large unconditional grants from the central government are unlikely to merge.     

Role of linking mechanisms in multitask agency with hidden information

We investigate the adverse selection problem where a principal delegates multiple tasks to an agent. We characterize the virtually implementable social choice functions by using the linking mechanism proposed by Jackson and Sonnenschein (2007) [20] that restricts the message spaces. The principal does not require any incentive wage schemes and can therefore avoid any information rent and welfare loss. We show the resemblance between the functioning of this message space restriction and that of incentive wage schemes. We also extend the results of the single-agent model to the multi-agent model.     

Estimates of average marginal tax rates on factor incomes in Japan

In this paper, we estimate average marginal tax rates on factor incomes in Japan from 1963 to 2007. We adapt the method of D.H. Joines [Estimates of effective marginal tax rates on factor incomes. J. Bus. 54 (2), 191-226.] to the Japanese tax and social security system. Average marginal tax rates on labor incomes without social security premiums range from 14% to 21%, whereas the rates on incomes with social security have increased from 21% to 33%. Tax rates on capital incomes have fluctuated between 35% and 58%. We also compare our estimates with average tax rates and the wedges from business cycle accounting.     

The properties of some covariance matrix estimators in linear models with AR(1) errors

A Monte Carlo study is used to demonstrate how poor some traditional covariance matrix estimators can be in linear models with AR(1) errors. It is also shown that a second-order approximation suggested recently by Ullah et al. (1983) does not lead to a more accurate covariance matrix estimator.     

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.     

Examining the relationship between municipal consolidation and cost reduction: an instrumental variable approach

This study explores the cost-reduction effects of local government consolidation, using data from Japanese municipalities. We use municipal panel data from Japan for the years 2000, 2005 and 2010, a data set including numerous consolidation cases. Reverse causality between consolidation decisions and size of municipal expenditure is a concern in the voluntary consolidation of local governments. An instrumental variable (IV) methodology is employed to deal with possible endogeneity associated with consolidation decisions. The main finding is that municipal current expenditure per capita increases immediately after consolidation, but then gradually declines. Because consolidation seems to increase per capita expenditure in the absence of the effect of this long-term declining trend, incorporating this trend into estimation is crucial in cost-efficiency analysis of consolidation. It is also shown that conventional panel data regressions yield biased consolidation effects, suggesting the superiority of the IV approach.     

Technological innovation and diffusion of wind power in Japan

The purpose of this paper is to analyze the diffusion of wind power in Japan by focusing on the value chain and the interaction between technology and markets and to contribute towards recommendations on technology policy and management. This paper proposes a framework for analyzing the early stage diffusion of wind power systems by combining the use of several approaches considering wind power system as a complex technological system. Firstly, the business system approach is used as an analytical framework by focusing on efficiency, effectiveness and development criteria. As a second approach, the technological trajectory was analyzed based on the concept of technological disequilibrium and the evolutionary patterns of innovation of wind power generation systems were analyzed and the relationship between innovations at the sub-system, modular, and system level was identified. We apply the framework to investigate why wind power diffusion has not picked up momentum in Japan.The results include the following: (1) Technological imbalances within the product system were solved by technological innovation (2) The wind power business in Japan is insufficiently effective due to organizational disequilibrium (3) The technology system has begun to evolve in the direction of micro grid systems. (4) It is important to consider the demand-pull measures for wind power generation so that Japanese institution can have a “time slot” for ”learning by doing” to catch up and accelerate diffusion of wind power generation, including institutional reform of RPS law. Also further technological development related to stabilizing unstable wind energy is required.     

Researcher Interaction Biases and Business Ethics Research: Respondent Reactions to Researcher Characteristics

The potential for biased responses that occur when researchers interact with their study participants has long been of interest to both academicians and practitioners. Given the sensitive nature of the field, researcher interaction biases are of particular concern for business ethics researchers regardless of their preference for survey, experimental, or qualitative methodology. Whereas some ethics researchers may inadvertently bias data by misrecording or misinterpreting responses, other biases may occur when study participants’ responses are systematically influenced by the mere introduction of researchers into the participants’ environment. Although substantial empirical research has been conducted on the general topic of researcher interaction biases, none has focused specifically on business ethics research. In order to remedy this lack of empirical substantiation in the field, we review the related literature on researcher interaction biases, present an empirical example of how such biases can influence research results in an experiment assessing reactions to insurance fraud, and discuss the implications for business ethics research.     

The influence of cause-related marketing on consumer choice: Does one good turn deserve another?

Are consumers more likely to select brands offered by companies that engage in cause-related marketing (CRM)? Somewhat surprisingly, little evidence exists that directly addresses this issue. Accordingly, the present examination investigates whether and when CRM efforts influence consumer choice. The results from several studies indicate that information regarding a company’s support of social causes can affect choice. However, CRM’s influence on choice is found to depend on the perceived motivation underlying the company’s CRM efforts as well as whether consumers must trade off company sponsorship of causes for lower performance or higher price. The results also indicate that CRM cues affect choice primarily through compensatory strategies involving trade-offs rather than through noncompensatory strategies. Implications of the current findings for existing theory are discussed along with directions for future research.
