Assistant Professor
Profile
Yu is currently working on his doctoral dissertation on elections and corruption, drawing on fieldwork conducted in Tanzania, an East African country. As in many other developing countries, reports indicate that during election periods—and even in everyday life—candidates and their brokers distribute a range of goods to voters, from cash to T-shirts, through various means. From an external perspective, these practices are often framed as bribery, vote-buying, or clientelism. However, his conversations with local people revealed that not all of these exchanges were perceived as bribery, vote-buying, or "dirty money"; some were regarded as entirely legitimate. Notably, the reasoning behind these distinctions was rarely grounded in legal frameworks. Yu's research explores the criteria by which these transactions are evaluated and, more broadly, what it implies. While his current focus is on Tanzania and Africa, he hopes to expand his work to include comparative studies with other regions, including Asia.

    票の売買とは、政治家と有権者とが、少額の現金等と投票とを交換する約束を交わす行為を指す。またこのように、公の規則に則らない形で配布される利益と政治的支持とが交換される政治的関係は、広くクライエンテリズムと呼ばれ、特に途上国の政治における課題として大きく注目されている。本研究は票の売買に特に注目し、それが途上国で継続して行われている背景の解明を目指すものである。実は現代の多くの途上国では秘密投票が確保されており、有権者は投票所では自由に投票が可能である。ではそれにもかかわらず、票の売買が継続して行われているのはなぜなのだろうか。タンザニア農村における現地調査を通じてその一端を明らかにしたい。
