Demographic Transition and Fertility Rebound in Economic Development*

Recent evidence on the “fertility rebound” offers credence to the idea that, from the onset of early industrialization to the present day, the dynamics of fertility can be represented by an N-shaped curve. An overlapping generations model with parental investment in human capital can account for these observed movements in fertility rates during the different stages of demographic change. A demographic transition with declining fertility emerges at the intermediate stage, when parents engage on a child quantity–quality trade-off. At later stages, however, the process of economic growth generates sufficient resources so that households can rear more children while still providing the desirable amount of education investment per child.     

Overcoming coordination failure using a mechanism based on gradualism and endogeneity

We examine three tools that can enhance coordination success in a repeated multiple-choice coordination game. Gradualism means that the game starts as an easy coordination problem and moves gradually to a more difficult one. The Endogenous Ascending mechanism implies that a gradual increase in the upper bound of coordination occurs only if coordination with the Pareto superior equilibrium in a stage game is attained. The Endogenous Descending mechanism requires that when the game’s participants fail to coordinate, the level of the next coordination game be adjusted such that the game becomes simpler. We show that gradualism may not always work, but in such instances, its effect can be reinforced by endogeneity. Our laboratory experiment provides evidence that a mechanism that combines three tools, herein termed the “Gradualism with Endogenous Ascending and Descending (GEAD)” mechanism, works well. We discuss how the GEAD mechanism can be applied to real-life situations that suffer from coordination failure.     

A statistical model of speculative bubbles,with applications to the stock markets of the United States,Japan, and China

It is common knowledge that the more prices deviate from fundamentals, the more likely it is for prices to reverse. Taking this into account, we propose a simple statistical model to identify speculative bubbles in financial markets. Through the estimates of the time varying parameters, including transition probabilities, we can identify when and how newly born bubbles grow and burst over time. The model can be estimated by recursive computations, which require a huge storage capacity for standard computers. For this reason, we introduce an approximation in the computation, maintaining the recursive nature of our estimation technique. We then apply this model to the stock markets of the United States, Japan, and China, estimate its parameters and the probabilities of a bubble crash, and obtain several interesting results: the time series data of the stock price bubble show an inherently non-stationary development and the probability of a bubble crash indeed increases as the stock price becomes too high or too low.

The rise and fall of deficit in Japan, 1965–1990

This paper investigates the fifteen-year period when the Japanese government deficit (defined as the deficit bond issues to the general budget) rose sharply and shrank to zero. Our main contribution is to differentiate the budget “plan” and the “actual” (ex post) budget in order to distinguish intention and surprise. From 1976 to 1979, deficit bonds were considered to be deliberately increased, because of little surprise (deviations of actual from planned budget) in deficits for these years. The deficit ratio was brought down in the 1980s, mainly by freezing expenditures at the nominal level and waiting for bracket creeps in taxes to catch up. Beyond a trend increase in the 1970s and a trend decrease in the 1980s, the Japanese government acted to pursue a fiscal expenditure fine-tuning.     

Corporate governance beyond the shareholder–stakeholder dichotomy: Lessons from Japanese corporations' environmental performance

Although corporate environmental performance (CEP) is determined by corporate governance (CG) typified by board and ownership structures, in‐depth research on stakeholder‐oriented CG is sparse. This study seeks to fill this void and promote an alternative vision of good governance. Japanese corporations have often been criticized for their stakeholder‐oriented practices such as less independent boards and the dominance of stable domestic shareholders. However, these practices are not necessarily problematic if effective monitoring mechanisms are in place. Using a database of Japanese listed corporations over 2012–2015, this study shows that both board size and composition enhance CEP, confirming the advisory function of boards. Contrastingly, foreign blockholders, who are expected to play a monitoring role, significantly constrain CEP. Japanese corporations are evolving toward a hybrid CG that aims to narrow the shareholder–stakeholder divide, and the findings will offer useful lessons for the modification of shareholder‐oriented CG.     

The Role of Interregional Trade in Generating Change in the Regional Economies of Japan, 1980-1990

An earlier analysis (Hewings et al., 1998) revealed the 'hollowing-out' process, a decrease in the level of intraregional intermediation, in the Chicago economy during the period 1975-2011. The main force underlying this structural change has been the change in regional trade patterns in a way that interregional trades across economies has replaced the local purchases of intermediate inputs. The issue addressed in this paper focuses on the decomposition of structural change into changes in interregional trade and in technology, in order to investigate the nature of structural change over time and across sectors. The empirical realization is provided by reference to a series of regional input-output tables for a nine-region division of the Japanese economy (1980-1985-1990). The results revealed that interregional trade has played a key role in determining regional output level while technology itself had a tendency to decrease further.     

Partially Binding Platforms: Campaign Promises vis‐à‐vis Cost of Betrayal

This study examines and models the effects of partially binding campaign platforms in a political competition. Here, a candidate who implements a policy that differs from the platform must pay a cost of betrayal, which increases with the size of the discrepancy. I also analyse endogenous decisions by citizens to run for an election. In particular, the model is able to show two implications that previous frameworks have had difficulty with. First, candidates with different characteristics have different probabilities of winning an election. Second, even knowing that he/she will lose an election, a candidate will still run, hoping to make an opponent's policy approach his/her own policy.
