Using a simple downstream duopoly model with vertical relations and downstream R&D, we investigate the effect of non-assertion of patents (NAP) provisions. A monopoly upstream firm decides whether to employ NAP provisions. If it does so, it freely incorporates the R&D outcomes into its inputs....

We examine how vertical separation affects the lobbying activities for the access charge of essential facilities. First, when investigating a model where the number of new entrants is fixed, we find that vertical separation either increases or decreases the access charge, and that this depends...

I investigate the effect of exclusive territories, which are typical vertical controls imposed by upstream firms. Using shipping spatial models, I consider an industry that consists of many independent local markets. An upstream monopolist restricts competition between downstream firms using...
