We study price discrimination in a monopolistic software market. The monopolist charges different prices for the upgrade version and for the full version. Consumers are heterogeneous in taste for infinitely durable software and there is no resale. We show that price discrimination leads to a...

Spatially dispersed production and processing, endemic for most agricultural or renewable resource markets, causes oligopsonistic competition. The possibility and use of spatial price discrimination in these markets is well documented. It is also well known that the location of processors...
