IZA Discussion Paper No. 1872
Social interaction is the primary vehicle through which advancement of information and communication technologies (ICT) affects socio-economic outcomes. In the context of minority-majority relations, social distances and segregation determine the benefits individuals gain from social interaction and from improvement of its efficiency. In the general equilibrium framework, this paper argues that ICT advancement disproportionately increases the efficiency of social interaction in ethnically integrated social networks and that of majority individuals, thereby causing desegregation and increasing interethnic earnings inequality at the same time. The argument thus explains the concurrence of two seemingly contradicting developments in the lives of Black and White Americans since the late 1970s - rising interethnic earnings inequality and desegregation of Blacks. Furthermore, I establish that there is a threshold level of ICT below which all minority individuals prefer segregated neighborhoods and above which some minority individuals choose to integrate, thereby reaping the efficiency benefits of social interaction with the larger society. I interpret the reversal of the segregation trend that occurred in the late 1970s as a consequence of advancement of ICT beyond this threshold level. Finally, I suggest an explanation of why typically no desegregation occurred in extraordinarily segregated areas and in the case of recent immigrants.
