Social Relationship of a Firm and the CSP–CFP Relationship in Japan: Using Artificial Neural Networks

As a criterion of a good firm, a lucrative and growing business has been said to be important. Recently, however, high profitability and high growth potential are insufficient for the criteria, because social influences exerted by recent firms have been extremely significant. In this paper, high social relationship is added to the list of the criteria. Empirical corporate social performance versus corporate financial performance (CSP–CFP) relationship studies that consider social relationship are very limited in Japan, and there are no definite conclusions for the studies in the world, because of scant data and the inappropriate methods, especially for supporting linear hypothesis which these studies are based on. In this paper, the CSP–CFP relationship is analyzed by an artificial neural networks model, which can deal with a non-linear relationship, using 10-year follow-up survey data.

Spatial analysis of competition among local governments and the price of land: the case of Zhejiang Province

Abstract

This empirical study focuses on competition between local governments as they strive to attract companies through the auction of land use rights. In the literature on competition between local governments, the focus has tended to be toward growth rates based on performance evaluation or tax rate-based competition for attracting companies. In China, the property tax system is still underdeveloped and local governments cannot independently set tax rates. Therefore, this study focuses on a type of ‘dumping’ activity by which local governments auction land use rights to attract industrial companies and empirically test this hypothesis using the spatial lag model.     

Sequential mergers and competition policy under partial privatisation

We examine optimal merger and privatisation policies in a partially privatised oligopoly with differentiated goods. We first show that under the subgame perfect Nash equilibrium, sequential mergers either emerge completely or do not emerge at all. Given this outcome, we derive the following policy implications. First, the level of social welfare can be U‐shaped with respect to the number of merged firm pairs. That is, given that there are some mergers that have already taken place, further mergers may actually lead to welfare improvement. However, these welfare‐improving mergers may not be privately profitable, implying that merger‐friendly policies are appropriate. Second, policymakers can halt privatisation in order to diminish the private incentive for further sequential (welfare‐deteriorating) mergers and improve welfare. Third, full nationalisation is never optimal unless the goods are homogeneous or independent. Our results are applicable to the Japanese life insurance industry and the partial privatisation of Japan Post Insurance.

Natural or unnatural selection? The end of lending relationships for small businesses

We investigate the situation where small business borrowers and banks end their lending relationships. If credit allocation is efficient, banks terminate their relationships with risky borrowers. Alternatively, small business borrowers are more likely to end their relationships when they have poor investment opportunities and do not require borrowed funds. However, if the soft budget constraints of banks or credit crunches are a significant problem, banks are likely to continue their relationships with risky firms or end their relationships with nonrisky firms, which is representative of an unnatural credit allocation. Using Japanese firm-level data, we show empirically that these relationships end naturally, with natural credit allocation supported even during the recent global financial crisis.     

Log Mean-Variance Portfolio Selection Under Regime Switching

In this paper we develop a portfolio selection theory under regime switching means and volatilities. We use log mean-variance as the portfolio selection criteria and, as a result, the theory is made substantially easier to implement than other existing theories. Moreover, the estimated regimes are easy to interpret as one of the regimes corresponds to the business cycle turning points. Finally, we conduct an asset allocation simulation and obtain reasonable results by introducing an idea of switching volatility targets.     

Do Trees Grow with the Economy? A Spatial Analysis of the Determinants of Forest Cover Change in Sichuan,China

This paper aims to identify the relationship between economic growth and forest cover change in Sichuan, China. Using a set of panel land use data based on Landsat TM/ETM digital images, we show that during the late 1980s and 1990s, Sichuan’s forest cover initially decreased and then rose. We also note that the rising and falling trends occurred at the same time that Sichuan’s economy was going through a period of rapid and sustained growth. We use multivariate analysis to identify the determinants of forest cover change. In addition to using a first-differenced estimator, we also utilize spatial error and spatial lag models to obtain consistent and efficient estimates of the determinants of forest cover. Our analysis demonstrates the importance of economic growth on the forest cover change; the results show that there is a U-shaped relationship between forest cover and GDP per capita. However, despite the nature of the empirical relationship between forest cover and income, the high turning point of the U-shaped relationship suggests that there is no evidence for the existence of the Environmental Kuznets Curve for forests in Sichuan Province. Hence, policy interventions may be necessary to stop the decrease of forests.     

Rationalizable foresight dynamics

This paper proposes and studies the rationalizable foresight dynamics. A normal form game is repeatedly played in a random matching fashion by a continuum of agents who make decisions at stochastic points in time. A rationalizable foresight path is a feasible path of action distribution along which each agent takes an action that maximizes his expected discounted payoff against another path which is in turn a rationalizable foresight path. We consider a set-valued stability concept under this dynamics and compare it with the corresponding concept under the perfect foresight dynamics.     

Does corporate board downsizing increase shareholder value? Evidence from Japan

Japanese firms that have traditionally had large boards have recently become subject to pressures for small boards. This study shows that Japanese firms that substantially decreased board size tended to adopt an officer system and so did not substantially decrease the size of the management team (executive officers and directors). This tendency is especially evident for high-performing firms that face less information asymmetry. Japanese firms endogenously choose the change in the management team size when downsizing their boards. Firms that downsize boards do not show performance improvements, suggesting that board downsizing does not necessarily raise shareholder value.     

Robust equilibria under non-common priors

This paper considers the robustness of equilibria to a small amount of incomplete information, where players are allowed to have heterogeneous priors. An equilibrium of a complete information game is robust to incomplete information under non-common priors if for every incomplete information game where each player's prior assigns high probability on the event that the players know at arbitrarily high order that the payoffs are given by the complete information game, there exists a Bayesian Nash equilibrium that generates behavior close to the equilibrium in consideration. It is shown that for generic games, an equilibrium is robust under non-common priors if and only if it is the unique rationalizable action profile. Set-valued concepts are also introduced, and for generic games, a smallest robust set is shown to exist and coincide with the set of a posteriori equilibria.
