INSTITUTIONAL INVESTORS,CORPORATE GOVERNANCE AND FIRM PERFORMANCE IN JAPAN

Since the beginning of the 2000s, institutional investors in Japan have become active in strengthening corporate governance, with the aim of achieving long‐term corporate value. The present paper examines the relationship between institutional investors and corporate governance, and also the relationship between institutional investors' shareholdings and firm performance. The results suggest that corporate governance has been enhanced by institutional investors. However, it is found that there is not a statistically significant difference between institutional investors' shareholdings and firm performance.     

The Effects of Liquidity Shocks on Corporate Investments and Cash Holdings: Evidence from Actuarial Pension Gains/Losses

This paper investigates how anticipated liquidity shocks affect corporate investment and cash holdings by examining the impacts of actuarial pension gains/losses that do not reduce current internal resources but will reduce those available in the future. Using a sample from Japanese manufacturing firms in which pension deficits had a huge impact on the internal resources of sponsoring firms, I show that pension losses significantly decrease the capital expenditures of sponsoring firms. Pension losses also increase corporate cash holdings, suggesting precautionary demands for cash prepared for future pension contributions. Overall, the results indicate that managers consider anticipated liquidity shocks in determining current investment and cash‐saving policies.     

Detecting motives for cooperation in public goods experiments

This study clarifies the types of motives that are important as a source of cooperation in a linear public goods experiment. Our experimental design separates contributions into those due to confusion, one-shot motives (which includes altruism, warm-glow, inequality aversion, and conditional cooperation), and multi-round motives (which includes a strategic motive under incomplete information, a failure of backward induction, and reciprocity). The experiment reveals that multi-round motives plays an important role in driving cooperative behavior. Confusion and one-shot motives play a minor role.     

Usefulness of the Information Contained in the Prediction Sample for the Spatial Error Model

A recent study proposed an estimation approach that uses data on the independent variables and location for the prediction sample, and suggested that it may improve estimation and prediction. This is an incomplete data approach following an iterative process along the lines of the EM algorithm. The present study compares this approach with a partial data approach that uses only data on the dependent and independent variables and location for the estimation sample. Our Monte Carlo experiments show that unless the estimation and prediction samples constitute the whole population and the data generating model is used as the data fitting model, the incomplete data approach is not guaranteed to be superior to the partial data approach.     

WHY DO LARGE FIRMS TEND TO INTEGRATE VERTICALLY?

We provide a theoretical framework to discuss the relation between firm size and vertical structures. The framework is based on a Hotelling model with three downstream and three upstream firms. We show that vertical integration enhances the degree of product differentiation and show the strategic complementarity of product positioning. We also show that the downstream firm that has the largest market share is more likely to integrate vertically. Enhancing the degree of product differentiation is more beneficial for the large firm than for the rest of the downstream firms because the large firm supplies a large amount of product.     

Pre‐commitment to an Exclusive Contract under Partial Regulation

This article examines the welfare implications of an incumbent’s pre‐commitment to an exclusive contract in a partially regulated environment. It shows that the contract offered to customers in a competitive market makes the first‐best allocation infeasible in the partially regulated environment. However, the contract can have a welfare‐enhancing property through the exclusion of inefficient entry or cream skimming in the competitive market, especially when the regulated price ceiling is low and the incumbent’s technology is characterized by a large proportion of common cost in total cost.     

Delegating Infrastructure Projects with Open Access

This paper provides a simple model that examines a firm's incentive to invest in a network infrastructure through coalition formation in an open-access environment with a deregulated retail market. A regulator faces a dilemma between inducing an incentive for efficient investment and reducing the distortion generated by imperfect competition. We show that, in such a case, the degree of the cost-reducing effect of the investment is crucial from a welfare point of view. In particular, when network investment through coalition formation creates a large (small) cost-reducing effect, the regulator can (should not) delegate an investment decision to firms with an appropriate level of access charge.     

Elderly labor supply and fertility decisions in aging-population economies

With a longer life expectancy, individuals who plan to work when they are old may increase the number of their children. Therefore, when individuals choose the time of retirement, the fertility rate may not necessarily decline but even rise.     

Analysing Mechanism of an Economic Phase

In this paper, we define the thetical and antithetical phases of macroeconomy on a formal basis. And we formulate a bubble economy and its collapse by using these definitions. The concept of thetical and antithetical phases is introduced into economics by Kinoshita. In the course of discussion, we also make clear the difference between economic growth and bubble economy, while describing a mechanism of collapse of a bubble economy by using a simple macro-economic model instead of a specific model. As a result, we can analyse not only the state of thetical economy phase, and antithetical economy phase, but also bubble economy phase and bubble bursting economy phase. And we can describe mechanism of transitions among four economic phases.
