This course examines the emerging literature on networks and economic development. This course is divided into four sections: (i) Commitment—how communities can harness their pre-existing social connections to circumvent market imperfections in developing economies. (ii) Labor markets and Migration—how community networks can both facilitate and hinder the mobility of their members. (iii) Inter-group Interactions—how communities interact with each other in developing economies and societies. (iv) How information spreads, through social connections, in developing economies. Apart from providing a particular perspective on development, an additional objective of this course is to demonstrate the use of economic theory in informing empirical research.
