This paper analyses competition of moral norms and institutions in a society where a fixed share of people unconditionally complies with norms and the remaining people act selfishly. Whether a person is a norm-complier or selfish is private knowledge. A model of voting-by-feet shows that those...

We study an industry in which an upstream monopolist supplies an essential input at a regulated price to several downstream firms. Legal unbundling means that a downstream firm owns the upstream firm but this upstream firm is legally independent and maximizes its own upstream profits. We allow...

We study an industry with a monopolistic bottleneck (e.g. a transmission network) supplying an essential input to several downstream firms. Under legal unbundling the bottleneck must be operated by a legally independent upstream firm, which may be partly or fully owned by an incumbent active in...

Many successful franchise chains directly own a positive fraction of stores --- a structure referred to as plural form. We propose that this ownership structure is chosen as a commitment not to expropriate franchisees. The theoretical model is based on an empirical analysis of contract and...
