摘要:We consider a multimarket framework where a set of firms compete on two
interrelated oligopolistic markets. Prior to competing in these markets, firms
can spy on others in order to increase the quality of their product. We
characterize the equilibrium espionage networks and networks that maximize
social welfare under the most interesting scenario of diseconomies of scope. We
find that in some situations firms may refrain from spying even if it is
costless. Moreover, even though spying leads to increased product quality, there
exist situations where it is detrimental to both consumer welfare and social
welfare.
