Study: P2P effect on legal music sales "not statistically distinguishable from zer

A new study in the Journal of Political Economy by Felix Oberholzer-Gee and Koleman Strumpf has found that illegal music downloads have had no noticeable effects on the sale of music, contrary to the claims of the recording industry.

Entitled "The Effect of File Sharing on Record Sales: An Empirical Analysis," the study matched an extensive sample of music downloads to American music sales data in order to search for causality between illicit downloading and album sales. Analyzing data from the final four months of 2002, the researchers estimated that P2P affected no more than 0.7% of sales in that timeframe.

The study compared the logs of two OpenNAP P2P servers with sales data from Nielsen SoundScan, tracking the effects of 1.75 million songs downloads on 680 different albums sold during that same period. The study then took a surprising twist. Popular music will often have both high downloads and high sales figures, so what the researchers wanted was a way to test for effects on albums sales when file-sharing activity was increased on account of something other than US song popularity. Does the occasionally increased availability of music from Germany affect US sales?

The study looked at time periods when German students were on holiday after demonstrating that P2P use increases at these times. German users collectively are the #2 P2P suppliers, providing "about one out of every six U.S. downloads," according to the study. Yet the effects on American sales were not large enough to be statistically significant. Using this and several other methods, the study's authors could find no meaningful causality. The availability and even increased downloads of music on P2P networks did not correlate to a negative effect on music sales.

"Using detailed records of transfers of digital music files, we find that file sharing has had no statistically significant effect on purchases of the average album in our sample," the study reports. "Even our most negative point estimate implies that a one-standard-deviation increase in file sharing reduces an album's weekly sales by a mere 368 copies, an effect that is too small to be statistically distinguishable from zero."

The study reports that 803 million CDs were sold in 2002, which was a decrease of about 80 million from the previous year. The RIAA has blamed the majority of the decrease on piracy, and has maintained that argument in recent years as music sales have faltered. Yet according to the study, the impact from file sharing could not have been more than 6 million albums total in 2002, leaving 74 million unsold CDs without an excuse for sitting on shelves.

So what's the problem with music? The study echoes many of the observations you've read here at Ars. First, because the recording industry focuses on units shipped rather than sold, the decline can be attributed in part to reduced inventory. Gone are the days when Best Buy and others wanted a ton of unsold stock sitting around, so they order less CDs. The study also highlighted the growth in DVD sales during that same period as a possible explanation for why customers weren't opening their wallets: they were busy buying DVDs.

An experiment that hints we are wrong on climate change

When politicians and journalists declare that the science of global warming is settled, they show a regrettable ignorance about how science works. We were treated to another dose of it recently when the experts of the Intergovernmental Panel on Climate Change issued the Summary for Policymakers that puts the political spin on an unfinished scientific dossier on climate change due for publication in a few months’ time. They declared that most of the rise in temperatures since the mid-20th century is very likely due to man-made greenhouse gases.

The small print explains “very likely” as meaning that the experts who made the judgment felt 90% sure about it. Older readers may recall a press conference at Harwell in 1958 when Sir John Cockcroft, Britain’s top nuclear physicist, said he was 90% certain that his lads had achieved controlled nuclear fusion. It turned out that he was wrong. More positively, a 10% uncertainty in any theory is a wide open breach for any latterday Galileo or Einstein to storm through with a better idea. That is how science really works.

Twenty years ago, climate research became politicised in favour of one particular hypothesis, which redefined the subject as the study of the effect of greenhouse gases. As a result, the rebellious spirits essential for innovative and trustworthy science are greeted with impediments to their research careers. And while the media usually find mavericks at least entertaining, in this case they often imagine that anyone who doubts the hypothesis of man-made global warming must be in the pay of the oil companies. As a result, some key discoveries in climate research go almost unreported.

Enthusiasm for the global-warming scare also ensures that heatwaves make headlines, while contrary symptoms, such as this winter’s billion-dollar loss of Californian crops to unusual frost, are relegated to the business pages. The early arrival of migrant birds in spring provides colourful evidence for a recent warming of the northern lands. But did anyone tell you that in east Antarctica the Adélie penguins and Cape petrels are turning up at their spring nesting sites around nine days later than they did 50 years ago? While sea-ice has diminished in the Arctic since 1978, it has grown by 8% in the Southern Ocean.

Christina Aguilera Records Private Sex Track


Christina Aguilera may have come a long way from her "Dirrty" days, but the singer admits she still likes to get down and dirty behind closed doors and sing about raunchy subject matters.

Christina recently said she has recorded a song about oral sex but has vowed never to release it.

The singer revealed she laid down the X-rated track called "F*** You, Suck You" during one drunken night in the recording studio. And despite record producer Linda Perry's pleas, Christina says the only people who will get to hear the racy lyrics are her close friends.

Speaking at the Grammy Awards, she said, "We recorded it one night over whiskey in the studio. It's completely breathy. Linda wanted to put it out under someone else's name. But I play it when I have my friends over when we've had one too many and start rolling around the floor with each other."

The 26-year-old also confessed her own music is a turn-off when she is having sex with husband Jordan Bratman. She prefers the melancholic tones of British band Radiohead.

Christina explained, "I'd be too busy analyzing my own voice. I get very nitpicky. I like listening to Thom Yorke from Radiohead. That's good sexy-time music."

The raunchy star has previously revealed she tries to make love every day and made no secret of her openness to experimenting in the bedroom.

She said, "I'm a red blooded woman who doesn't feel guilty about making love. If a lover wants to experiment with handcuffs, then that's fair enough for me! What's the point of holding back that side of your personality if it's horny and turns you both on?"

Certain Windows Vista features will make your computer Less Reliable, Less Secure, Less Stable, Slower...

Windows Vista includes an array of "features" that you don't want. These features will make your computer less reliable and less secure. They'll make your computer less stable and run slower. They will cause technical support problems. They may even require you to upgrade some of your peripheral hardware and existing software. And these features won't do anything useful. In fact, they're working against you. They're digital rights management (DRM) features built into Vista at the behest of the entertainment industry.

And you don't get to refuse them.

The details are pretty geeky, but basically Microsoft has reworked a lot of the core operating system to add copy protection technology for new media formats like HD-DVD and Blu-ray disks. Certain high-quality output paths--audio and video--are reserved for protected peripheral devices. Sometimes output quality is artificially degraded; sometimes output is prevented entirely. And Vista continuously spends CPU time monitoring itself, trying to figure out if you're doing something that it thinks you shouldn't. If it does, it limits functionality and in extreme cases restarts just the video subsystem. We still don't know the exact details of all this, and how far-reaching it is, but it doesn't look good.

Microsoft put all those functionality-crippling features into Vista because it wants to own the entertainment industry. This isn't how Microsoft spins it, of course. It maintains that it has no choice, that it's Hollywood that is demanding DRM in Windows in order to allow "premium content"--meaning, new movies that are still earning revenue--onto your computer. If Microsoft didn't play along, it'd be relegated to second-class status as Hollywood pulled its support for the platform.

It's all complete nonsense. Microsoft could have easily told the entertainment industry that it was not going to deliberately cripple its operating system, take it or leave it. With 95% of the operating system market, where else would Hollywood go? Sure, Big Media has been pushing DRM, but recently some--Sony after their 2005 debacle and now EMI Group--are having second thoughts.

What the entertainment companies are finally realizing is that DRM doesn't work, and just annoys their customers. Like every other DRM system ever invented, Microsoft's won't keep the professional pirates from making copies of whatever they want. The DRM security in Vista was broken the day it was released. Sure, Microsoft will patch it, but the patched system will get broken as well. It's an arms race, and the defenders can't possibly win.

I believe that Microsoft knows this and also knows that it doesn't matter. This isn't about stopping pirates and the small percentage of people who download free movies from the Internet. This isn't even about Microsoft satisfying its Hollywood customers at the expense of those of us paying for the privilege of using Vista. This is about the overwhelming majority of honest users and who owns the distribution channels to them. And while it may have started as a partnership, in the end Microsoft is going to end up locking the movie companies into selling content in its proprietary formats.

We saw this trick before; Apple pulled it on the recording industry. First iTunes worked in partnership with the major record labels to distribute content, but soon Warner Music's CEO Edgar Bronfman Jr. found that he wasn't able to dictate a pricing model to Steve Jobs. The same thing will happen here; after Vista is firmly entrenched in the marketplace, Sony's Howard Stringer won't be able to dictate pricing or terms to Bill Gates. This is a war for 21st-century movie distribution and, when the dust settles, Hollywood won't know what hit them.

To be fair, just last week Steve Jobs publicly came out against DRM for music. It's a reasonable business position, now that Apple controls the online music distribution market. But Jobs never mentioned movies, and he is the largest single shareholder in Disney. Talk is cheap. The real question is would he actually allow iTunes Music Store purchases to play on Microsoft or Sony players, or is this just a clever way of deflecting blame to the--already hated--music labels.

Microsoft is reaching for a much bigger prize than Apple: not just Hollywood, but also peripheral hardware vendors. Vista's DRM will require driver developers to comply with all kinds of rules and be certified; otherwise, they won't work. And Microsoft talks about expanding this to independent software vendors as well. It's another war for control of the computer market.

Unfortunately, we users are caught in the crossfire. We are not only stuck with DRM systems that interfere with our legitimate fair-use rights for the content we buy, we're stuck with DRM systems that interfere with all of our computer use--even the uses that have nothing to do with copyright.

I don't see the market righting this wrong, because Microsoft's monopoly position gives it much more power than we consumers can hope to have. It might not be as obvious as Microsoft using its operating system monopoly to kill Netscape and own the browser market, but it's really no different. Microsoft's entertainment market grab might further entrench its monopoly position, but it will cause serious damage to both the computer and entertainment industries. DRM is bad, both for consumers and for the entertainment industry: something the entertainment industry is just starting to realize, but Microsoft is still fighting. Some researchers think that this is the final straw that will drive Windows users to the competition, but I think the courts are necessary.

In the meantime, the only advice I can offer you is to not upgrade to Vista. It will be hard. Microsoft's bundling deals with computer manufacturers mean that it will be increasingly hard not to get the new operating system with new computers. And Microsoft has some pretty deep pockets and can wait us all out if it wants to. Yes, some people will shift to Macintosh and some fewer number to Linux, but most of us are stuck on Windows. Still, if enough customers say no to Vista, the company might actually listen.
