Does garbage pricing increase the immoral disposal of household waste?

Some empirical studies have attempted to clarify the mechanism of illegal dumping by examining the degree to which per-bag pricing plays a role. However, previous research on the behaviour of avoiding paying a charge for waste collection has tended to neglect so-called ‘immoral disposal,’ which is less risky than illegal dumping because there is no legal penalty. In this study, we define immoral disposal as the dumping of waste in a manner that is immoral but not illegal. To detect the existence of immoral disposal, we apply a spatial econometric approach, namely an extended panel spatial Durbin model, to identify the actual spillover effect of garbage pricing in neighbouring municipalities on immoral disposal from the total waste. A major finding of this study is that immoral disposal exists in unit-based pricing, two-tiered pricing, and fixed pricing.     

The power of social media in regional tourism development: a case study from Ōkunoshima Island in Hiroshima,Japan

This research letter introduces a new insight into the power of social media in tourism development using a case study from ōkunoshima Island in Hiroshima, Japan. The island has been experiencing an unprecedented tourism boom since 2014, when videos posted by social media led to an increase in international tourists in a formerly domestic destination. The results of our structured interviews suggest that tourists acquired information about the island through social media. This result implicated social media’s power in developing tourism in peripheral regional areas, which are often left out from the international tourism circuit.     

Robust portfolio estimation under skew-normal return processes

In this paper, we study issues related to the optimal portfolio estimators and the local asymptotic normality (LAN) of the return process under the assumption that the return process has an infinite moving average (MA) (∞) representation with skew-normal innovations. The paper consists of two parts. In the first part, we discuss the influence of the skewness parameter δ of the skew-normal distribution on the optimal portfolio estimators. Based on the asymptotic distribution of the portfolio estimator ? for a non-Gaussian dependent return process, we evaluate the influence of δ on the asymptotic variance V(δ) of ?. We also investigate the robustness of the estimators of a standard optimal portfolio via numerical computations. In the second part of the paper, we assume that the MA coefficients and the mean vector of the return process depend on a lower-dimensional set of parameters. Based on this assumption, we discuss the LAN property of the return's distribution when the innovations follow a skew-normal law. The influence of δ on the central sequence of LAN is evaluated both theoretically and numerically.     

Informal parental care and female labour supply in Japan

Using the Japanese Study of Aging and Retirement, Japan’s first globally comparable panel survey of the elderly, we estimate the effect on female employment in Japan due to the provision of informal parental care. We observe that informal parental care has little impact on female employment, after controlling for endogeneity of informal care or individual unobserved time-invariant heterogeneity. This finding is consistent with those observed in Europe and the US, underscoring a limited association between care and work in Japan, which is facing ageing at the fastest pace among advanced economies.     

Voluntary adoption of ISO 14001 in Japan: mechanisms,stages and effects

This paper seeks to understand what factors contribute to voluntary adoption of the ISO 14001 environmental management system by private sector facilities in Japan. A model based on regulatory, competitiveness, social responsibility and organization theory is applied to 1999 survey data. Analysis shows systematically different factors to be important indicators of voluntarism in different industries and for facilities at different stages of certification. First adopters and second adopters appear to be fundamentally different types of organizations driven by different internal and external factors. Although results do not indicate a clear causal linkage between ISO adoption and greening activity, evidence shows that at least two different stages of adoption have taken place in Japan and that ISO adoption is associated with environmental action.

The role of newly emergent wholesalers in the food and drink industry in Japan,c.1880 to 1940: Focusing on the case of Kokubu

Abstract

This article explores the historical development of Japanese wholesalers in the food and drink industry in modern Japan. Despite many criticisms of Japanese wholesalers as being “multi-layered,” “old-fashioned,” and “outmoded,” there were historical reasons for the existence of wholesalers. While the traditional wholesalers remained even after the Meiji Restoration, the new wholesalers emerged by dealing with new products that appeared for the first time in modern Japan. Utilizing the historical conditions of both producers and retailers, the newcomers such as Kokubu boosted their development by innovative activities and gradually superseded the traditional wholesale market, firmly establishing their position as general wholesalers before the Second World War.     

Wages,non-wage characteristics,and predominantly male jobs

This paper estimates the wage premium associated with working in predominantly male jobs. It also examines whether this wage premium is greater than the compensation workers demand for the less desirable non-wage characteristics of such jobs. The coefficients of the change in the proportion of men in an occupation on the change in wages for quits and layoffs provide opposing biased estimates of the wage premium; because workers who voluntarily quit move to better matches, but those that are laid off accept jobs from the representative distribution of job offers. Specifically, when the premium paid over- (under-)compensates for undesirable work characteristics, the quit estimate is a downward (upward) biased estimate of the wage premium, while the layoff estimate is biased upward (downward). Results from the U.S. National Longitudinal Survey of Youth (NLSY) and the U.S. Panel Study of Income Dynamics (PSID) indicate that: (1) the estimated bounds of the wage premium are large; and (2) the wage premium overcompensates for the non-wage characteristics of male jobs.
