Outline Activities
I have researched economic valuation and optimum usage of non market goods, agricultural land and aquaculture farm depend on nature.
Current researches I am working are as follows;

-To evaluate an environmental load reduction in the reusing system of organic waste treatments
-To analyze the ripple effects by introduction of new technology on aquaculture industries in Tohoku area
-To research what factors affect to Eco-friendly behavior on the basis of behavioral economics

Our laboratory including me, has much knowledge about evaluation methodology such as Conjoint analysis, CVM, Life cycle analysis, AHP and so on.
Please join our laboratory!

Current and Past Project
  • Our research is to analyze how to allocate information to prompt moral behavior, using prospect theory based on behavior economics. And then we suggest effective information service for environmental conservation.
  • Our research is to suggest sustainable management model of silver salmon not to be affected by imported salmon from Chile.
  • Our research is to evaluate a new fishery products developed by new technology, and then suggest marketing strategy and management model

1. Le Thi Thanh Loan, Yoshifumi Takahashi, Hisako Nomura and Mitsuyasu Yabe, Modeling home composting behavior toward sustainable municipal organic waste management at the source in developing countries, Resources, Conservation and Recycling, 140, 65-71, 2019.02, Home composting (HC) has become an increasingly important consideration in the framework of sustainable municipal organic waste (MOW) management in developing countries. We develop, for the first time, two HC behavior models, which include households’ decisions to participate in a HC scheme and the level of HC participation. By applying Logit and Ordered logit models, a survey of 202 respondents in rural areas of Hoi An, Vietnam, indicates that households’ decisions to get involved in a HC scheme and the level of HC participation are affected by motivational factors such as knowledge about HC, attitude toward it, and owning a garden. We then explore the differences between the influencing factors for the two models. Interestingly, while participation in the HC training program influence the decision to participate in the HC scheme, the factor appears unimportant in increasing the level of HC practice. In addition, once the HC participation decision has been made, we find that pro-environmental behavior (such as habit of reusing plastic bags and reducing wastefulness) could promote a higher level of HC practice. These findings could help policy makers in promoting HC behavior to enhance a sustainable MOW management strategy at the household level..

a structural equation modeling approach, Journal of Material Cycles and Waste Management, 10.1007/s10163-017-0587-3, 19, 3, 1052-1060, 2017.02, Most recent municipal organic waste-separation at source (MOW-SAS) programs that have been introduced in developing countries remain pilot programs, but have not fully developed into sustainable municipal solid-waste management strategies. The city of Hoi An, Vietnam, implemented a mandatory MOW-SAS program in 2012. Using Structural Equation Modeling, this study investigates the psychological driving forces behind households’ behaviors toward the MOW-SAS program. This study finds that moral norm (moral perception of what is good or bad), attitude toward sorted waste, and situational factors (issues concerning physically sorting garbage, such as time, space, and lack of family cooperation) can significantly affect household behaviors toward MOW-SAS. It confirms the need for supplying frequent environmental educational campaigns and highlighting the benefits of MOW-SAS programs. Moreover, the study finds that households’ system trust in local authority concerning the MOW-SAS program is an important driving force behind the behavior. Therefore, recommendation is also made on the need to develop strong leadership in local authorities through improving: (1) reliability (ability to effectively treat sorted waste), (2) legitimacy (punitive measures for non-participants), and (3) effectiveness (dissemination of information about the benefits of MOW-SAS programs) for promoting MOW-SAS..

Awards
  • Unit non-response has been recognized as a potential problem because it may cause the bias in the inference of important parameters. In this research, we investigate the non-response bias in Contingent Valuation (CV) by using Inverse Probability Weighting (IPW). In the application of IPW, however, one of the major problem is the inaccessibility to auxiliary variables. We could deal with this inaccessibility problem when we use internet-based research because it is available that the individual information registered to the internet research company as auxiliary variables. We apply IPW to evaluate consumers' willingness to pay for a grass-fed beef stake
    produced by environmentally friendly farming system.
    The result in the logistic regression of the response propensity shows that response propensity have the relation to personal income, age, characteristics of family member, use of SNS or video distribution websites, and hobbies. On the other hand, there is almost no difference between the respondents’ mean of WTP and population mean of WTP estimated by IPW. From this survey, there is no evidence that these differences in auxiliary variables between respondents and non-
    respondent cause non-respondent bias in the estimation of consumers’ WTP for a grass-fed beef.
