Kuhn-Tucker modelは，近年研究され始めた顕示選好データを用いた便益評価手法であり，端点解を柔軟に利用可能なことが特徴である．顕示選好データを用いた便益計測では，関数形の選択が便益値に影響することは広く知られている．一方，Kuhn-Tucker modelでは，効用関数の形状が便益計測に与える影響について検証した研究は少ない．そのため，本研究は6種類の効用関数形を用い，関数の形状と便益値の関連性を分析した．宮城県の26箇所の海水浴場のレクリエーション活動のデータから年当たりの便益計測を行ったところ，Phaneuf and Siderelis (2003)もしくはWhitehead et al.(2010)で用いられた関数形による便益計測が望ましいという結果が得られた．
Ongoing international climate negotiations are putting greater emphasis on the need for greater cooperation between developed and developing countries as well as among developing countries in order to promote climate change adaptation at all institutional levels. The pace at which adaptation is being implemented, however, does not meet the demands of climate sensitive communities due to various institutional barriers. While various adaptation networks, both globally and in the Asia-Pacific region, have recently formed to overcome these barriers, they have not met their full potential in enabling economies to become climate resilience. Among these is the lack of communication and collaboration among different domains of expertise. In this paper, we examine the role of existing networks, the stakeholders involved, operational modalities, and their expected outcomes and we identify recent activities that are helping to overcome these barriers and creating synergy by improving efficiency, strengthening coordination, and aiding in the convergence of multiple priorities.
