When institutions matter: a gravity model for Chinese meat imports
Sign Up to like & getrecommendations! Published in 2019 at "International Journal of Emerging Markets"
DOI: 10.1108/ijoem-11-2016-0290
Abstract: Purpose In international trade differences in political and legal systems confront trading partners with relatively greater information asymmetry and contract enforcement problems than in domestic trade, resulting in higher transaction costs. Nevertheless, well-functioning institutions in… read more here.
