Digitization has vastly increased the amount of new music produced and available directly to consumers. While this has levelled the playing field between already-prominent and new artists, creators may now be dependent on platform decisions about which songs and artist to promote. With Spotify...

We explore the consequence of quality unpredictability for the welfare benefit of new products, using recent developments in recorded music as our context. Digitization has expanded consumption opportunities by giving consumers access to the “long tail” of existing products, rather than...

Ad blockers allow Internet users to obtain information without generating ad revenue for site owners; and by 2016 they were used by roughly a quarter of site visitors. Given the ad-supported nature of much of the web, ad blocking poses a threat to site revenue and, if revenue losses undermine...

In theory, free entry can lead to social inefficiency. We study the radio industry in a first attempt to quantify this inefficiency. Using cross-sectional data on advertising prices, the number of stations, and radio listening, we estimate the parameters of listeners' decisions and of firms'...

A vast theoretical literature shows that inefficient market structures may arise in free entry equilibria. Previous empirical work demonstrated that excessive entry may obtain in local radio markets. Our paper extends that literature by relaxing the assumption that stations are symmetric,...

Since the launch of the iTunes Music Store in the US in 2003 and in much of Europe in the following years, music trade has shifted rapidly from physical to digital products, raising the availability of products in different countries. Despite substantial growth in availability, choice sets have...

The objective of this paper is to document the evolution of cross-border music trade patterns in this transition period and to explain what drives digital music trade patterns. The shift from analogue to digital music distribution has substantially reduced trade costs and has enlarged the choice...

Each year individuals in the U.S. transfer between $50 and $72 billion in resources to friends and family members in the form of noncash holiday gifts, despite the fact that holiday gift recipients apparently value their noncash gifts at about ten percent less than the prices paid by the givers....
