二十一世紀以來的國際發展援助議程益加強調援助有效性，如何確立援助過程中最後階段—政策到發展結果—的有效性，則與2015年 2019年與2021年諾貝爾經濟學獎得主，使用個體資料、應用因果推論方法、進行反事實分析緊密相關。本文回顧援助有效性的背景，介紹反事實分析的邏輯、方法，並透過訪談與文獻分析，檢視臺灣目前政府開發援助中，已獲學術期刊審查刊登的反事實分析案例，包括國際合作發展基金會在南太平洋島國吉里巴斯與馬紹爾群島的園藝計畫以及海地之糧食安全計畫。本文發現上述案例..

Since the beginning of the twenty-first century, the international development agendas have put more emphases on aid effectiveness. How to ensure the effectiveness from policies to development outcomes, the last stage of the aid process, is closely related to counterfactual analyses using micro-level data and causal inference techniques, recognized by Nobel Memorial Prizes in economics in 2015, 2019, and 2021.

The so-called semi-presidentialism designs a system that popularly elects both the president and the parliament. Under the dual-election design, the parliament theoretically should own more check and balance power than a parliament that gives rise to the cabinet. However, whether the parliament under semi-presidentialism in practice is indeed equipped with more oversight capacity than that of a cabinet system’s parliament has been rarely studied in prior literature. This paper tries to study this theoretically inte..
