Simply examining changes in sales after the shutdown would produce an inaccurate measure of its actual effect as sales are changing over time for a variety of reasons. Instead we exploit cross- country variation in pre-shutdown usage of Megaupload as a measure of treatment intensity. Controlling for country-specific trends and the Christmas holiday, we find no statistical relationship between Megaupload penetration and changes in digital sales prior to the shutdown. However, we find a statistically significant positive relationship between a country’s Megaupload penetration and its sales change after the shutdown, such that for each additional 1% pre-shutdown Megaupload penetration, the post-shutdown sales unit change was 2.5% to 3.8% higher, suggesting that these increases are a causal effect of the shutdown.Of course, there's still the effect of "competition" with pirated downloads which spurred movie studios to offer online services in the first place, but it's interesting to see a seemingly high-quality study that shows the effect go in this direction. Most of the others show piracy increasing sales.

Remix culture has come full circle
Gotye’s stunt reminded me of an argument I first heard from the academic Karl Hagstrom Miller: In the 21st century, we have circumnavigated back to the late 19th, when pop was a participatory sport, and the amateur was the star. As in 1890, the real musical action these days is taking place at home. And the laptop camera is the new parlor room piano.From Slate.

Natural experiments and movies
Peukert and Claussen. Piracy and Movie Revenues: Evidence from Megaupload. In this paper we make use of a quasi-experiment in the market for illegal downloading to study movie box office revenues. Exogenous variation comes from the unexpected shutdown of the popular file hosting platform Megaupload.com on January 19, 2012. The estimation strategy is based on a quasi difference-in-differences approach. We compare box office revenues before and after the shutdown to a matched control group of movies unaffected by the shutdown. We find that the shutdown had a negative, yet insignificant effect on box office revenues.This counterintuitive result may suggest support for the theoretical perspective of (social) network effects where file-sharing acts as a mechanism to spread information about a good from consumers with zero or low willingness to pay to users with high willingness to pay.

It would be interesting to try to quantify quite how many public domain works are locked up inside paywalls. Easier to come up with a number of works than with a valuation on their economic value.

The interesting point here for me is not the smoking gun or the conspiracy theory or somesuch. Rather, I've assumed for a while that such evidence has made it into the hands of executives, either via the public domain or via commissioned reports. What's clear is that the decision-making process has simply ignored the evidence over and over again. It's not a phenomenon unique to one industry (or government, or even sometimes academia), sadly. For all the rise in "data scientist" positions at corporations, for all Netflix and Google's success, evidence is still a second class citizen.

A Generation of Software Patents
James E. Bessen
This report examines changes in the patenting behavior of the software industry since the 1990s. It finds that most software firms still do not patent, most software patents are obtained by a few large firms in the software industry or in other industries, and the risk of litigation from software patents continues to increase dramatically. Given these findings, it is hard to conclude that software patents have provided a net social benefit in the software industry.

On the other hand, being in Paris for the summer, I have discovered a huge downside: because you don't actually own your media, artificial restrictions get put in place. Not only do subscription services like Netflix stop working, but even movies that you ostensibly paid for with Amazon's video-on-demand service stop working. If you're going to charge the same price that the physical media costs, at least make it just as useful.

"According to research group NPD Group, the shuttering of Limewire's music file sharing service has led to a similar decline in the usage of such services throughout the U.S. The number has gone from a high of 16 percent in the fourth quarter of 2007 to just nine percent in the fourth quarter of 2010, right after Limewire shut down its file-sharing services due to a court order, when a federal judge sided with the Recording Industry Association of America (RIAA)."

Japanese econometrics study: Filesharing boosts DVD sales
"Whether or not illegal copies circulating on the internet reduce the sales of legal products has been a hot issue in the entertainment industries. Though much empirical research has been conducted on the music industry, research on the movie industry has been very limited. This paper examines the effects of the movie sharing site Youtube and file sharing program Winny on DVD sales and rentals of Japanese TV animation programs. Estimated equations of 105 anime episodes show that (1) Youtube viewing does not negatively affect DVD rentals, and it appears to help raise DVD sales; and (2) although Winny file sharing negatively affects DVD rentals, it does not affect DVD sales. Youtube’s effect of boosting DVD sales can be seen after the TV’s broadcasting of the series has concluded, which suggests that not just a few people learned about the program via a Youtube viewing. In other words YouTube can be interpreted as a promotion tool for DVD sales."
I wish there were an English translation, now that I've spent all this time learning econometrics....
