Is corporate governance important for regulated firms’ shareholders?: Evidence from Japanese mergers and acquisitions

This paper compares the reaction of bidders’ stock prices to acquisition announcements by regulated non-financial firms, banks, and unregulated companies in Japan. Results suggest that regulated non-financial firms do not experience a significant stock price response at merger and acquisition (M&A) announcements, although banks’ and unregulated firms’ M&A announcements are regarded favorably by the stock market. Furthermore, the effect of stock option usage and strict boards on the stock price response is weak for regulated non-financial bidders. The results provide additional evidence that regulation results in managerial decisions’ having less influence on shareholder wealth and thereby changes the firm's optimal governance structure. In contrast, the results provide no clear evidence that, for bank bidders, there is a significantly stronger or weaker relationship between governance and the stock price response to an M&A announcement than that of unregulated firms or regulated non-financial firms. The result does not support the view that regulatory monitoring weakens the effect of ordinary governance mechanisms.     

Completing Incomplete Revealed Preference Under Limited Attention

This paper discusses how to improve the identification of the preference of a decision‐maker (DM) with limited attention proposed by Masatlioglu, Nakajima and Ozbay (2012). in “Revealed Attention”. Their identification method relies on choice reversals so the obtained revealed preference is often incomplete. We propose three approaches to address this problem. The first one is accommodating a model‐free approach, which respects the DM's choice in making a welfare analysis, as long as it does not contradict the revealed preference of Masatlioglu et al. The second approach incorporates the DM's exogenously obtained attention/inattention information into the model of Masatlioglu et al. The third approach is to take framings that influence the DM's attention into effect for the identification.     

Optimal inflation target under uncertainty

We derive an optimal state-contingent inflation target in an economy under uncertainty. This inflation target can improve inefficiencies stemming from two sources: the lack of commitment to predetermined policies and the lack of coordination between the monetary and fiscal authorities. We then discuss the pros and cons of our proposal compared with the solution proposed by Beetsma and Bovenberg [Beetsma, R.M.W.J., Bovenberg, A.L., 2001. When does an inflation target yield the second best? Scandinavian Journal of Economics 103, 119–126], paying special attention to their practical feasibility. We will show that in some countries where there is a highly independent central bank, our proposal is more attractive.     

p-Dominance and Equilibrium Selection under Perfect Foresight Dynamics

This paper studies equilibrium selection based on a class of perfect foresight dynamics and relates it to the notion of p-dominance. A continuum of rational players is repeatedly and randomly matched to play a symmetric n×n game. There are frictions: opportunities to revise actions follow independent Poisson processes. The dynamics has stationary states, each of which corresponds to a Nash equilibrium of the static game. A strict Nash equilibrium is linearly stable under the perfect foresight dynamics if, independent of the current action distribution, there exists a consistent belief that any player necessarily plays the Nash equilibrium action at every revision opportunity. It is shown that a strict Nash equilibrium is linearly stable under the perfect foresight dynamics with a small degree of friction if and only if it is the p-dominant equilibrium with p<1/2. It is also shown that if a strict Nash equilibrium is the p-dominant equilibrium with p<1/2, then it is uniquely absorbing (and globally accessible) for a small friction (but not vice versa). Set-valued stability concepts are introduced and their existence is shown. Journal of Economic Literature Classification Numbers: C72, C73.     

A GM(1,1)–Markov chain combined model with an application to predict the number of Chinese international airlines

In this paper, we propose a new dynamic analysis model which combines the first-order one-variable grey differential equation model (abbreviated as GM(1,1) model) from grey system theory and Markov chain model from stochastic process theory. We abbreviate the combined GM(1,1)–Markov chain (MC) model as MCGM(1,1) model. This combined model takes advantage of the high predictable power of GM(1,1) model and at the same time take advantage of the prediction power of Markov chain modelling on the discretized states based on the GM(1,1) modelling residual sequence. For prediction accuracy improvements, Taylor approximation is applied to MCGM(1,1) model. We call the improved version as T-MCGM(1,1) model. As an example, we use the statistical data of the number of Chinese international airlines from 1985 to 2003 for a validation of the effectiveness of the T-MCGM(1,1) model.     

Evaluation of the impact of the tourism nation promotion project on inbound tourists in Japan: a difference-in-differences approach

This study quantitatively evaluates the impact of the Tourism Nation Promotion Project on tourism demand. Data were obtained from Japan Tourism Agency’s quarterly survey from 2010Q2 to 2015Q4. Cox and zero-truncated negative binomial models and difference-in-differences approach were applied to analyze tourism demand and the project’s impact on inbound tourists’ length of stay and expenditure in Japan. Empirical results showed a positive and significant average treatment effect on length of stay and expenditure for tourists from Australia, China, Russia, and Thailand. These findings indicate that the Japanese government should use differentiated strategies considering different nationalities’ characteristics to attract foreign tourists.     

Cultivated land conversion and potential agricultural productivity in China

In China there is a growing debate on the role of cultivated land conversion on food security. This paper uses satellite images to examine the changes of the area of cultivated land and its potential agricultural productivity in China. We find that between 1986 and 2000 China recorded a net increase of cultivated land (+1.9%), which almost offset the decrease in average potential productivity, or bioproductivity (−2.2%). Therefore, we conclude that conversion of cultivated land has not hurt China's national food security. We also argue that more recent change in cultivated area likely has had little adverse effect on food security.     

ENDOGENOUS FLEXIBILITY IN THE FLEXIBLE MANUFACTURING SYSTEM

We investigate the flexible manufacturing system (FMS) by using the spatial price discrimination framework of Pal. The degree of flexibility when producing variants can be increased by increasing the investment or production cost and is endogenously determined. Our result is that private incentives for increasing flexibility are excessive from a social welfare perspective.     

Does an extrinsic reward for R&D employees enhance innovation outcomes? Evidence from a Japanese innovation survey

This paper examines the effects of extrinsic rewards for R&D employees on innovation outcomes based on evidence from a Japanese innovation survey. Theoretical and empirical studies present conflicting findings regarding the relationship between extrinsic rewards and innovation outcomes. This article seeks to shed light on the relationship between rewards and outcomes, as represented by the development of new products and services and their technological superiority and profitability. The analysis produced the following findings. First, companies that have introduced an evaluation system based on R&D performance are more likely to develop new products and services. The introduction of the evaluation system brings about success in product innovation with greater technological superiority. Second, monetary compensation has a negative impact on the development of new products and services and technological superiority. Third, these effects vary with the company size. Small- and medium-sized companies achieve higher technological superiority with performance-based evaluations. Large companies tend to adversely impact the development of new products and services and their technological superiority with monetary compensation.
