摘要：
This paper provides a perspective to explain different properties of networks with different link formation requirements. We propose a CES link formation specification that generalizes commonly used link formation assumptions adopted in existsing literatures. The CES specification also enables the investigation on how the subsitutability of link investments determines network structures. We apply our novel link formation specification to two well-known network formation models and illustrate that link investment subsitutability is closely tied to the emergence of various network properties, among which is the unequalness of networks that has great social and economic implications.
