What Should the Weights of the Three Major Currencies be in a Common Currency Basket in East Asia?*

We consider what type of regional common currency should be introduced in East Asia in the future. The common currency basket is, in itself, more desirable as an anchor currency. In this paper we define two types of currency basket and investigate the long‐term sustainability of adopting a common currency basket in East Asia. From our empirical results, a larger weight (but less than 100 percent) for the US dollar in the common currency basket tends to make bilateral exchange rates among East Asian countries stable in the long run.     

Fairness and the Unselfish Demand for Redistribution by Taxpayers and Welfare Recipients

We theoretically illustrate how the aversion to unfairness triggers an unselfish though rational demand for redistribution. This leads the well-off to demand positive tax rates and the “poor” to reject extreme progressivity. We prove that the “rich” and the “poor” adjust their demand for redistribution in opposite ways when their sensitivity to fairness increases: while agents with above average expected income raise their demand for redistribution, agents with below average income lower it. We then provide empirical evidence of these behaviors using a nationally representative survey from Italy. The estimates confirm that a stronger aversion to unfair distributive outcomes is associated with a higher support for redistribution by individuals with high income and to a lower demand for redistribution by those with low income.     

Does ownership of an end-of-life product affect design for environment?

Circulative use of resources is a crucial concept for a modern capitalist economy. Faced with peaking-out of material resources and shortage of landfill capacity in the long run, human beings are required to promote efficient reuse and recycling of end-of-life products (ELPs). One of the methods to advance efficient reuse and recycling is rental or lease of products. Product service is also a similar idea. All these imply, in some sense, a change of ownership of a product and an ELP; ownership of an ELP as well as a product belongs to producers instead of households. It is often said that such a change of ownership promotes design for environment (DfE) or eco-design, contributing to circulative use of resources. This paper examines whether ownership of an ELP affects DfE by means of à la Sraffian type of equilibrium model. I show that there are two routes to DfE, namely via a reduction of the amount of an ELP and enhancement of quality of a secondary material. I also show that DfE effects do not appear under certain conditions, even if the ownership of an ELP is transferred to producers.     

What Does Trade Openness Measure?

An empirical measure of trade openness is defined as the ratio of total trade to GDP, and represents a convenient variable routinely used for cross‐country studies on a variety of issues. However, the effects that the crude measure captures remain ambiguous, making it difficult to interpret the empirical results. Drawing on several strands of the literature, this study examines the informational content of the trade openness measure using intranational and international data. We find that, even for fully integrated economies within a country, trade openness is approximately half as variable as it is for segmented diverse countries around the world. The information it conveys is better characterized as the extent of the economic remoteness and idiosyncratic distribution of sectoral production. The cross‐country variation of trade openness derives more from the variability in GDP than trade.     

Effects of Pregnancy and Birth on Smoking and Drinking Behaviours: A Comparative Study Between Men and Women

Using panel data obtained from monthly surveys for 3 years, we examined how the effects of life events on smoking and drinking behaviours differ between men and women. The key findings were that: (i) consumption of alcohol and cigarettes by men and women were lower during pregnancy and after childbirth than before pregnancy; (ii) pregnancy and childbirth led women to stop drinking and led men to reduce their alcohol consumption but not to stop drinking; and (iii) marriage, pregnancy and childbirth led women to stop smoking and marriage and birth led men to stop smoking but the effects of pregnancy on men are unclear.     

Influence of body image in urbanized areas: differences in long-term changes in teenage body mass index between boys and girls in Japan

Japanese prefecture level panel data for the period 1986?C2003 was used to analyze and compare the determinants of teenage body mass index (BMI) by sex. Major findings through random effects estimation were as follows: BMI was not influenced by the degree of population density in males and younger females. However, the BMI of 16-year-old females was markedly lower in more densely populated residential areas. These findings suggest that girls who reach adolescence are more likely to diet and that this tendency is more distinct in more urbanized areas.     

Asymptotic properties of the efficient estimators for cointegrating regression models with serially dependent errors

In this paper, we analytically investigate three efficient estimators for cointegrating regression models: Phillips and Hansen’s [Phillips, P.C.B., Hansen, B.E., 1990. Statistical inference in instrumental variables regression with I(1) processes. Review of Economic Studies 57, 99–125] fully modified OLS estimator, Park’s [Park, J.Y., 1992. Canonical cointegrating regressions. Econometrica 60, 119–143] canonical cointegrating regression estimator, and Saikkonen’s [Saikkonen, P., 1991. Asymptotically efficient estimation of cointegration regressions. Econometric Theory 7, 1–21] dynamic OLS estimator. We consider the case where the regression errors are moderately serially correlated and the AR coefficient in the regression errors approaches 1 at a rate slower than 1/T$1/T$, where T$T$ represents the sample size. We derive the limiting distributions of the efficient estimators under this system and find that they depend on the approaching rate of the AR coefficient. If the rate is slow enough, efficiency is established for the three estimators; however, if the approaching rate is relatively faster, the estimators will have the same limiting distribution as the OLS estimator. For the intermediate case, the second-order bias of the OLS estimator is partially eliminated by the efficient methods. This result explains why, in finite samples, the effect of the efficient methods diminishes as the serial correlation in the regression errors becomes stronger. We also propose to modify the existing efficient estimators in order to eliminate the second-order bias, which possibly remains in the efficient estimators. Using Monte Carlo simulations, we demonstrate that our modification is effective when the regression errors are moderately serially correlated and the simultaneous correlation is relatively strong.     

Recycling and Landfilling in a Dynamic Sraffian Model: Application of the Corn–guano Model to a Waste Treatment problem

Landfill sites may be regarded as input for a waste treatment process. Considering landfill as an exhaustible resource, we apply a basic corn–guano model to a waste treatment problem. We show how dynamic substitution between landfilling and recycling occurs. Namely, in an early stage, landfill disposal is adopted as waste treatment and a recycling process is not activated. Once an economy faces exhaustion of landfill, a recycling process is activated as a backstop technology. We refer to the possibility that an economy may be unstable after exhaustion of landfill, even if it enjoys stable growth at the early stage.     

Dynamics of social trust and human capital in the learning process: The case of the Japan garment cluster in the period 1968–2005

This paper examined the ways and the extent to which human capital and social trust are associated with the learning process of a manager in making operations decisions through experience. To this end, using a data set originally and purposively constructed by the author, I investigated the development and transformation of the garment industry cluster region of Kojima, Japan. The major findings through statistical estimations are as follows. (1) In the cluster development stage, the social trust of an enterprise and its manager's experiences in firm operations could be regarded as forming a complementary association. (2) In the stage following cluster development, however, a manager's human capital as accumulated through schooling and personal experience, instead of social trust, become complementary.
