When deciding whether to share information, firms consider their private welfare. Discrepancies between social and private welfare may lead firms excessively to share information to anti-competitive ends - in facilitating of cartels and other harmful horizontal practices - a problem both...

Some path-breaking work on mergers takes efficiency gains for granted, or assumes that firms have perfect knowledge when taking merger decisions. In practice, firms and competition authorities cannot know exact future efficiency gains, prior to merger consummation. This paper analyzes horizontal...

This paper analyses the profitability of horizontal mergers in a Stackelberg model and their impact on welfare when there is uncertainty about the marginal costs of the newly merged firms. The authors consider that the merging firms decide their production strategy knowing the actual value of...

Although outsourcing vs. vertical integration is generally treated as a binary choice in international trade literature, firm-level data reveal that inputs can be imported both within and across firms' boundaries, even within narrowly defined industries from the same host country. This paper...

This study investigates whether having an upstream or downstream agent privately observe an interim performance measure and disseminating this measure to the other agent is valuable to the principal. The signal is informative about the upstream agent’s action and positively correlated with...

A physician performs two tasks: making diagnoses and determining treatments. To reduce medical error, residents are supposed to consult their supervisors when they face uncommon circumstances. However, recent research shows that residents are reluctant to do so. This paper presents a model that...

In complex insurance contracts, individuals can use sophisticated strategies to avoid out-of-pocket expenses. Sophistication and expected claims are affected by similar factors, creating a systematic positive or negative correlation between them. Depending on this correlation, sophistication can...

We derive the optimal selling mechanism for a monopolist who is privately informed about the attributes of a horizontally differentiated good. To do so, we set up an informed principal problem in a Hotelling model where the buyer's preferences are described in terms of a base consumption value...

How should firms be incentivized to adopt new technologies when the technical merits and spillovers of such technologies are uncertain? We show that, when information is dispersed but exogenous, efficiency can be induced with simple (constant) subsidies. When, instead, firms must also be...

This paper considers a dynamic duopoly market with strategic, price setting firms and an infinite set of fully rational, privately informed consumers who enter the market sequentially. I show that there exists a sequential equilibrium in which prices converge to their realized product qualities...
