Abstract Merger control authorities may approve a merger based on an “efficiency defense.”
An important aspect in clearing mergers is that the efficiencies need to be merger-specific.

In this article, we examine why it is difficult to induce firms to form Research Joint Ventures
(RJVs). We examine various incentives and disincentives for RJV formation by estimating an
endogeneous switching model using data from the US National Cooperative Research ...
