This paper analyses the incentives of a vertical integrated Internet service provider (ISP) to block competitors from content markets. Using a simple model we find that the ISP does not block competing content providers as long as the contents are differentiated sufficiently. Exclusion only...

Recent empirical studies suggest a need for a flexible patent regime responding to industry characteristics. In practice, sector-specific modifications of patent strength already exist but lack theoretical foundation. This paper intends to make up for this neglect by scrutinizing in what...

The debate on whether COVID-19 vaccine patents are slowing down the pace of vaccination and the recovery from the crisis has brought the optimal design of pharmaceutical patent policy to the fore. In this paper we evaluate patent policy in the US pharmaceutical industry. We estimate the effect...

In this paper, we review the literature on declining business dynamism and its implications in the United States and propose a unifying theory to analyze the symptoms and the potential causes of this decline. We first highlight 10 pronounced stylized facts related to declining business dynamism...

We analyze firms’ incentives to cluster in an industrial district to benefit from reciprocal technology spillovers. A simple model of cumulative innovation is presented where technology spillovers arise endogenously through labor mobility. It is shown that firms’ incentives to cluster are...

We show that when the researcher’s (observable but not contractible) contribution to innovation is crucial, a covenant not to compete (CNC) reduces e.ort and profits under both spot and relational contracts. Having no CNC allows the researcher to leave for a rival. This alleviates a commitment...

This paper quantifies the relationship between private-network file sharing activity and music sales in the BitTorrent era. Using a panel dataset of 2,251 albums' U.S. sales and file sharing downloads on a private network during 2008, I estimate the effect of file sharing on album sales....

Die Inhaber der Rechte an Musikstücken drängen auf einen wirksamen Schutz vor der unberechtigten Nutzung der von ihnen verlegten Titel. Anbieter von Musik-Download-Diensten haben daher Programme entwickelt (Digital Rights Management Systems, DRMS), die unter anderem das Kopieren verhindern...

Patents are one of the most valuable sources of technical and commercial knowledge. Although patents are public and can be easily searched on the Web, for most countries, there is no easy way to download bulk patent data. The purpose of this paper is to create a web mining framework used to...
