りスイッチング・コストを減少させ，消費者の携帯電話会社間の流動性を高めるものと考えられる．本論文では，MNP制度の導入に伴うスイッチング・コストの減少効果を定量的に評価することを目的とする．分析では，携帯電話会社の選択とMNP制度の利用の選択に関する離散選択モデルを定式化し，ウェブアンケート調査から得られた個票データを用いて，推定を行う．本論文での分析の結果，MNP制度の導入により，スイッチング･コストは18%程度減少し，携帯電話の所有者に占める携帯電話会社の変更者の割合が約2.6%増加したことを示した．","subitem_description_type":"Abstract"}]},"item_12_description_7":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"JEL
