We model a two-level supply chain where Nash bargaining occurs upstream, while firms compete in a differentiated products logit setting downstream.The parameters of this model can be calibrated with a discrete set of data on prices, margins, and market shares. Using a series of numerical...

We study the welfare impacts of mergers in markets where some firms are already vertically integrated. Our model features logit Bertrand competition downstream and Nash Bargaining upstream. We numerically simulate four merger types: vertical mergers between an unintegrated retailer and an...
