  • Decomposing Vietnamese gender equality in terms of wage distribution

    Vu T., Yamada H.

    Pacific Economic Review （Pacific Economic Review)  23 （ 5 ） 705 - 731 2018年12月

    ISSN  1361374X

    　概要を見る

    © 2018 John Wiley & Sons Australia, Ltd We decompose the gender wage gap in terms of wage distribution in Vietnam during 2002–2014 using two methods. The first method uses two estimated counterfactual distributions; the second uses an estimated recentred influence function. We focus on the formal sector and find evidence for a consistent gender wage gap, with the price of skills being the main contributor. In contrast, labour market discrimination does not have a crucial influence. Some gender equality gained by the distribution of skills can be explained by the rise in women's education and women's participation in specific industries, occupations and the growing private sector.

  • Life course consequences of low birth weight: Evidence from Japan

    Matsushima M., Shimizutani S., Yamada H.

    Journal of the Japanese and International Economies （Journal of the Japanese and International Economies)  50   37 - 47 2018年12月

    ISSN  08891583

    　概要を見る

    © 2018 Elsevier Inc. This study provides the first evidence on a variety of life course outcomes of birth weight in Japan by employing new datasets covering the middle and older generations. We have several interesting observations. First, low birth weight is significantly associated with adverse outcomes in early life including school performance and self-rated health. Second, no negative effect of low birth weight is found on educational attainment or primary job status. Third, health outcomes due to low birth weight at older ages are not negatively affected except for difficulty in mobility and higher risk of diagnosis with hypertension or diabetes. Overall, our findings suggest that the negative effect of lower birth weight seems to fade out over the life course.

  • The Effects of Risk Preferences on the Adoption of Post-Harvest Technology: Evidence from Rural Cambodia

    Shimamoto D., Yamada H., Wakano A.

    Journal of Development Studies （Journal of Development Studies)  54 （ 10 ） 1819 - 1837 2018年10月

    ISSN  00220388

    　概要を見る

    © 2017, © 2017 Informa UK Limited, trading as Taylor & Francis Group. We investigate how rice farmers’ risk preferences affect the adoption of post-harvest technology in Cambodia, focusing on moisture meters. We find that risk-averse farmers are more likely to adopt moisture meters, although the degree of farmers’ loss aversion or the extent to which they tended to overweight small probabilities do not affect the adoption. In the setting of our study, the effects of farmers’ risk preferences on agricultural technology adoption can be described by using expected utility theory. However, controlling for loss aversion and probability weighting improves the precision of examining the effects of farmers’ risk preferences on adoption.

  • Health Insurance Coverage and Firm Performance: Evidence Using Firm Level Data from Vietnam

    Yamada H., Vu T.

    B.E. Journal of Economic Analysis and Policy （B.E. Journal of Economic Analysis and Policy)  18 （ 4 ）  2018年

    　概要を見る

    © 2018 Walter de Gruyter GmbH, Berlin/Boston. In literature, there is limited direct evidence regarding the effect of health insurance coverage on firm performance and worker productivity. We study the impacts of health insurance on medium-and large-scale domestic private firms' performance and productivity in Vietnam, using a large firm level census dataset. We find statistically, but suggestive, positive health insurance effects on both aggregate profit and profit per worker for both complying and non-complying firms when using the full sample. We further restrict the sample to specific industries. The positive health insurance effects could exist for both complying and non-complying firms in the heavy manufacturing and construction sector, while such positive effects could be only significant for complying firms in the wholesale/retail sectors. We could not find any evidence of positive health insurance effects in the light manufacturing sector. These results imply that the impacts of health insurance could be industry specific.

    本研究ではベトナム統計局が収集している企業レベルのミクロデータを用い、こと可能な限りパネルデータ化を行って、ベトナムの様々な社会経済の構造変化をとらえる実証的な分析を試みた。具体的には、外資系企業の生存要因分析に関する研究、ベトナムへの対外直接投資はその出資国によってベトナム国内産業の生産性へもたらす影響に違いがあるのか?、医療保険加入と企業のパフォーマンスの間に関係性はあるのか、といったトピックを扱った。また輸入浸透度と国内雇用といった先進国にも共通するトピックに関しては、ベトナムに加えて日本の工場レベルのデータを用いた分析も行った。
