Abstract
Overseas presidential visits are an essential diplomatic activity that support official development aid (ODA) for humanitarian and strategic purposes worldwide. This study examines the effects of such visits on bilateral ODA allocation by focusing on South Korea, which achieved economic development through foreign aid, subsequently becoming a donor country. We find that presidential diplomatic visits abroad increase ODA agreements in visiting countries, confirmed through multiple robustness checks. ODA is increased through several aid delivery channels (concessional loans, public institutions, and summit meetings in recipient countries) with heterogeneous effects across regions. Thus, political leaders’ diplomatic visits are crucial to ODA allocation.
