We survey the literatures on the economic consequences of the structure of social networks. We develop a taxonomy of 'macro' and 'micro' characteristics of social inter-action networks and discuss both the theoretical and empirical findings concerning the role of those characteristics in...

We examine how participation in a microfinance program diffuses through social networks. We collected detailed demographic and social network data in 43 villages in South India before microfinance was introduced in those villages and then tracked eventual participation. We exploit exogenous...

We analyse the compatibility decisions of two national firms producing horizontally differentiated variants of a good that exhibits network effects for the world market. One of the firms is able to endogenously establish an installed base in its domestic market. The firm's effort in that respect...

We show that when the researcher’s (observable but not contractible) contribution to innovation is crucial, a covenant not to compete (CNC) reduces effort and profits under both spot and relational contracts. Having no CNC allows the researcher to leave for a rival. This alleviates a...

This Paper is concerned with the interaction between trade policies and the protection of Intellectual Property Rights (IPRs).
