We examine the interplay of endogenous vertical integration and costreducing downstream investment in successive oligopoly. We start from a linear Cournot model to motivate our more general reducedform framework. For this general framework, we establish the following main results: First,...

We analyze a Bayesian merger game under two-sided asymmetric information about firm types. We show that the standard prediction of the lemons market model-if any, only low-type firms are traded-is likely to be misleading: Merger returns, i.e. the difference between pre- and post-merger profits,...

We provide a framework for analysing bilateral mergers when there is two-sided asymmetric information about firms’ types. We introduce the concepts of essentially monotone decreasing (EMD) and increasing (EMI) functions, which generalize the respective mono-tonicity properties. If the profit...

We investigate how various institutional settings affect a network provider’s incentives to invest in infrastructure quality. Under reasonable assumptions on demand, investment incentives turn out to be smaller under vertical separation than under vertical integration, though we also provide...

We examine vertical backward integration in oligopoly. Analysing a standard linear Cournot model, we find that for wide parameter ranges (i) some firms integrate, while others remain separated, and (ii) efficient firms are more likely to integrate vertically. Adopting a reduced-form approach, we...

This paper provides a simple reduced-form framework for analyzing merger decisions in the presence of asymmetric information about firm types, building on Shapiro's (1986) oligopoly model with asymmetric information about marginal costs. We employ this framework to examine what types of firms...

We investigate how various institutional settings affect a network provider’s incentives to invest in infrastructure quality. Under reasonable assumptions on demand, investment incentives turn out to be smaller under vertical separation than under vertical integration, though we also provide...

We provide a framework for analyzing bilateral mergers when there is two-sided asymmetric information about firms’ types. We show that there is always a "no-merger" equilibrium where firms do not consent to a merger, irrespective of their type. There may also be a "cut-off" equilibrium if the...
