本文利用台灣延長中高齡失業勞工失業給付的政策變革來估計延長失業給付對保留工資的影響。從2009年開始，45歲以上失業勞工失業給付期限由6個月延長爲9個月，而45歲以下仍維持6個月。利用人力運用調查資料和差異中的差異法，我估計增加3個月的失業給付使得非自願失業勞工的保留工資上升約4-5%， 而傾向於用完6個月失業給付的勞工的保留工資上升尤其明顯。最後，將估計結果結合捜尋模型，本文估計增加失業給付的寬厚程度會提高中高齡勞工的福利水準。

This paper exploits an unemployment benefit extension for older workers in Taiwan to identify the effect of extended unemployment benefits on the reservation wage. Since 2009, the potential benefit duration for workers aged at least 45 at job loss has been 9 months rather than 6 months for those under 45. Using data from the Taiwanese Manpower Utilization Survey and a difference-in-differences design, I estimate that a three-month increase in potential duration of benefits increases the reservation wage for job losers by 4–5 percent. Moreover, the effect of extended benefits on the reservation wage is mainly driven by the reservation wage response during the extended benefit period and for workers who are most likely to exhaust their benefits. Combining the reduced-form estimates with a search model, my estimates suggest that it is welfare enhancing to increase the generosity of unemployment benefits for middle-aged workers.
