東京電力福島第一原子力発電所事故は,放射性物質の大量拡散をもたらした.食品の放射性物質による汚染は低い水準に抑えられているものの,放射性物質がこれまで直面したことのなかった危害因子であることから,消費者は不安と混乱のなかに置かれている.本論文では,食品中の放射性物質に関する科学情報をスライドショーとしてまとめ,このスライドショーによって消費者の意識がどのように変化するかを分析した.福島県と首都圏,関西圏に住む消費者を対象として,農産物としてキュウリを選び,インターネットを用いて調査を行った.福島県産の農産物は消費者に忌避されており,スライドショーは消費者の選好を変化させていた.本論文は,科学的な情報提供の有効性を示すものであるが,スライドショーに対する見方が分かれていることは,放射性物質に関するコミュニケーションの難しさを示している.不安の程度が比較的小さい消費者に対して,客観的データを提供することが有効だろう.

Research has shown that Japanese retailers have strong buying power when purchasing milk from processors, but not enough is known about differences in market competitiveness at the brand and retailer levels. In order to consider practical knowledges for the Japanese milk market, I used micro-level data to estimate a demand function using a random coefficient logit model that controls for the endogeneity of price due to unobserved heterogeneity. Then, I estimate the demand elasticity for each brand-retail combination in every prefecture each month. The markup was calculated from demand estimates. The results show that, on average, CO-OP milk tended to have a higher markup than NB and PB milk. Using counterfactuals, I find that 13% of milk products had a negative cost pass-through rate, which is concentrated in local NB milk. Finally, I show geographical differences in pass-through rates.

Though there are many studies on Japanese agricultural productivity, studies in relation to efficiency of Japanese agriculture are very few. In this study an attempt is made to measure the technical efficiency and technical change in Japanese agriculture from 1965 to 1995. Both data envelopment analysis (DEA) and stochastic frontier analysis (SFA) methods are used to measure the efficiency. We obtained a consistent result between these two analyses. We also found that a fair amount technical progress existed, but at the same time technical efficiency declined in these thirty years. Prefectures which have large-scale rice farming such as Hokkaido, Niigata, Ishikawa, and Toyama possess high technical efficiencies. Also, prefectures which are near big cities such as Tokyo, Kanagawa and Aichi possess high technical efficiencies. On the other hand, cold, mountainous and less populated prefectures such as Iwate, Tottori and Shimane possess low technical efficiencies. Also, we found that technical efficiency diverged rather than converged over these 30 years.
