Collaborative Research Group on Environmental Economics and Evaluation



Collaboration Between Social Science Fields and Biological/Ecosystem Fields

At the National Institute for Environmental Studies (NIES), the Social Systems Division and the Biodiversity Division have organized interdisciplinary seminars since 2011, with presentations from invited outside lecturers. We have been stimulating cross-disciplinary research activities and exploring the possibilities for solving conservation and management issues related to biodiversity and ecosystems.

Launch of the Collaborative Research Group on Environmental Economics and Evaluation

In August 2014, we launched the Collaborative Research Group on Environmental Economics and Evaluation (Group Leader: Professor Akira Hibiki of Tohoku University) to further promote research using a cross-disciplinary approach, based on the discussions conducted at previous seminars. The Group works on the analysis of environmental policies taking an integrated approach not only in the fields of social science and biology, but also in economics and other social and natural sciences. Information on past and future seminars will be announced on this page.

Title Green nudge messages and information-collection behavior of wineries: Field experiments in Japan
Abstract:Reducing greenhouse gas emissions from the agriculture, food, and beverage sectors is a challenge. In this paper, we study the decisions of 376 Japanese wineries to participate in webinars on life cycle assessment (LCA). We observe whether these wineries participate in the webinars. We find that 16% of the wineries registered for the webinars at least once, and 11% participated. Newer and larger wineries are more likely to participate in the webinars. Counter-intuitively, wineries that are highly aware of ongoing climate change are less likely to participate. These wineries may have already given up on climate change mitigation and are more interested in adaptation. Furthermore, we attempted to use a nudge message to encourage participation. We adopted the "leadership by example" concept and introduced a leading winery that had already purchased green electricity. However, this treatment does not encourage participation; we even find a negative effect on wineries close to the leading winery. Careful field surveys and policy design are required to advance climate change mitigation in this sector.

Abstract: This report introduces some findings on consumer evaluation of environmentally friendly agricultural products. First, we analyze scanner panel data for organic and specially cultivated agricultural products, and examine the characteristics of consumer evaluation and purchase motivation. Next, we will conduct a comparative analysis of Japan and Thailand using a virtual selection experiment on consumer evaluation of rice attributes, and point out that there is a potential purchasing power market in Southeast Asia as well.

Title: Driving the Gap: Tax Incentives and Incentives for Manipulating the Fuel Efficiency in the Automobile Industry
Abstract: This study examines and identifies the underlying incentives for falsifying fuel efficiency on the part of the automobile industry. Using novel microdata on on-road fuel consumption in Japan, we find a discontinuous increase in the fuel efficiency gap—the disparity between official test results and real-world fuel efficiency—of 6 percent at the tax-incentive eligibility thresholds. Further evidence shows that the extents of manipulation respond directly to marginal tax incentives. Our findings suggest that large incentive schemes, especially those with nonlinear payoff schedules, may induce incentives on the part of automakers to “cook the books” on fuel efficiency figures.

Title: Pollution Externalities and Corrective Taxes in a Dynamic Small Open Economy
Abstract: This study examines the effects of environmental tax policies in a dynamic model of a polluted small open economy in which there are two sources of pollution, consumption and production, controlled by consumption and income taxes, and accumulated pollution affects a negative effect on household's utility. In a decentralized dynamic competitive equilibrium under exogenous tax rates, we show that particularly a permanent increase in each of the consumption and income taxes unambiguously reduce the steady-state stock of pollution, a temporary increase in these taxes may lead to more pollution in We also derive the social optimal solution and examine the optimal tax paths to achieve the social optimum. If distaste and leisure effects are sufficiently strong, tax rates. decrease along the optimal path as pollution increases over time, and if these effects are not so stron g, the opposite occurs.

Title: Environmental policy in a stagnant economy (with Yoshiyasu Ono, ISER Osaka University)
Abstract: Using a dynamic optimization model of a monetary economy in which persistent unemployment occurs, we examine the effects of environmental policies on aggregate consumption and pollution emission in a stagnant economy with persistent deflation. If full employment is achieved, environmental policies, such as imposing If unemployment prevails, however, those environmental policies stimulate private consumption by expanding total employment and mitigating deflation. Their effects on welfare are also examined.

Title: A Subsidy Inversely Related to the Product Price
Abstract: This paper proposes a new subsidy scheme for promoting a target good's consumption, where subsidy payment is inversely related to the good's price. Under imperfect competition, this scheme makes the demand faced by producers more elastic, thereby reducing their power to raise prices and Increasing subsidy pass-through to consumers. Compared to commonly-used specific or ad valorem subsidies, it can lower government expenditure for inducing a given output, and flexibly adjust the incidence on producers. Simulations based on an actual U.S. subsidy programme on electric vehicles indicate up to 50-81% reductions in government spending if it replaces the current specific subsidy.

Title: The Competitiveness Impacts of Carbon Tax: Evidence from British Columbia
Summary: In the recent years, many jurisdictions have been considering a carbon pricing policy as their future climate action plan. To better inform policymakers and the public about the potential costs and benefits of such policies, I investigate the impacts of British Columbia's carbon tax. I use detailed confidential micro-level data to estimate its impacts on the competitiveness of plants and firms in BC. The findings from my research suggest that the carbon tax induces job shifts across industries while the net aggregate employment effect is rather small. However, it These findings can be useful for designing the future carbon tax policy does impose costs in the manufacturing sector in the short-run, leading to declines in output, employment, and productivity. Yet, such negative shocks can be eased by recycling the tax revenue. in other jurisdiction.

Title: Impact assessment in collaboration with practitioners: Introduction of randomized controlled trials on the impact of disability equality training in South Africa
Co-sponsored by:
Grant-in-Aid for Challenging Research (Exploratory) 17K18547 "Establishing RCT Methodology in the Environment and Energy Policy Research" (PI: Hisako Nomura; Co-Investigators: Hide-Fumi Yokoo, Takahiro Kubo, Aya Suzuki; Research Collaborators: Yohei Kobayashi, Ken Haig)
Abstract: With the recent advocacy of Evidence-Based Policy Making, the distance between researchers and practitioners has narrowed, and opportunities to jointly evaluate the impact of policy intervention have increased. However, the interests of researchers and practitioners often do not match, and it can be said that it is important to consider and adjust the intentions of both parties in order to carry out a fruitful impact evaluation. In this seminar, the Presenter:: will introduce the details of the research process such as the design of the evaluation design along with the analysis results, based on the case of the impact evaluation of the disability equality training in South Africa being carried out with JICA project experts.
