We compare four approaches to network neutrality and network management regulation in a two-sided market model: (i) no variations in Quality of Service and no price discrimination; (ii) variations in Quality of Service but no price discrimination; (iii) variations in Quality of Service and price...

This paper studies an industry where firms can choose to provide open or closed platforms. Open, as opposed to closed, platforms are extendable so that third-party producers can develop extensions for them. Building on a two-sided market model, I show that firms might prefer to commit to keeping...

Horizontal shifts in bid curves observed in wholesale electricity markets are consistent with Cournot competition. Quantity competition reduces the informational requirements associated with evaluating market performance because the markups of all producers then depend on the same inverse...

Previous research, notably Baumol (1990), has highlighted the role of insti-tutions in channeling entrepreneurial supply into productive, unproductive or destructive activities. However, entrepreneurship is not only influenced by institutions—entrepreneurs often help shape institutions...

The overwhelming majority of self-employed individuals are not entrepreneurial in the Schumpeterian sense. To unmistakably identify Schumpeterian entrepreneurs, we focus on self-made billionaires (in USD) from the Forbes Magazine list who became wealthy by founding new firms. In this way, we...

The purpose of this paper is to nuance the widely held view that well-functioning institutions are the ultimate prerequisite for innovation and entrepreneurship. This is done by putting the spotlight on the role that formal and informal institutions have in serving the economic status quo,...

The interplay between entrepreneurship and institutions is crucial for economic development; however, the view that institutions determine the extent to which entrepreneurial activity is productive is only part of the story. We argue that causality is bidirectional, in that entrepreneurship is...
