Princeton economics professor Alan Krueger examines the music industry, hoping to demonstrate the study of economics through the prism of popular music, and hoping to draw parallels to the economy at large. The result is more of a book about the music business than about economics, but I wager that most readers are more interested in the business than in economics, so consider that a success.
I may be an exception to the rule, having come close to getting a doctorate in economics myself -- Will Baumol, who is cited in this book several times, was supposed to be my committee chair until I decided not to proceed with my dissertation. But that was forty years ago, an interval in which my career had nothing whatsoever to do with economics (or music).
Still, I was hoping to see the application of economic theory to music -- I pictured a model of monopolistic competition where product differentiation in the form of signing and promoting unique artists and genres allowed suppliers to force consumers onto the inelastic portion of their demand curves, given the high utility consumers place on live and recorded music once they become fans of particular artists and styles.
If that last paragraph made your eyes and minds glaze over, perhaps that explains why Krueger made the wise choice not to go there -- except that he does talk about how artists are positioned as unique, as imperfect substitutes for each other, a key element of product differentiation.
Unfortunately, despite devoting an entire chapter to the gratification music gives us, Krueger doesn't place that within the context of consumer demand -- the concept of utility is in fact what underlies demand, even more so in the context of a experiential rather than tangible good like music. The various factors that shape utility in music makes demand potentially inelastic (inelastic demand allows suppliers to charge higher prices without dampening demand all that much) -- to me, that's a big part of how technology has affected pricing for live and recorded music.
Much is made of the music business being superstar driven, and that's a shame, because it really isn't. I live in New York, where there are three arenas in the area and half a dozen large concert halls, so there's maybe an average of one superstar event a day plus one or two next-level events. And then there are dozens of small theaters and hundreds of clubs that operate Every. Single. Night. Of the year.
In terms of the number of people performing, watching, and working, and the amount of business activity generated if you include food and drink, transportation, etc., I bet the superstar and next-level events are a drop in the bucket. In Nashville, performers have to pay clubs to play. People go to Chicago and New Orleans as well as Nashville and Brooklyn just to go club hopping. LA, Seattle, Boston, San Francisco, Atlanta, Philly, Portland -- just go down the list, the everyday music scene swamps the superstar events in sheer magnitude.
Similarly, one hundred miles west of NYC, in Bethlehem PA, there is probably an average of one star event a month (if that), but there is a vibrant music scene at lower levels that translates into dozens of events each day within an easily drive-able radius. As an amateur musician who spends time in that area, even the bottom-most-level open-mic business that allows me to pretend to be a musician is a bigger deal than superstar concerts.
The City Winery model is spreading all over the country. PACs are everywhere. Old theaters in relatively small cities and towns are being renovated into community theaters that mix concerts with other cultural events. There are so many of these venues in my area that I can't keep track of them all. Meanwhile, I almost never go to an arena concert, and never ever go to a stadium, not with all the other choices I have -- not worth the hassle or cost. This is a golden age for concert-goers, and that has nothing at all to do with superstar performers.
Krueger discusses literally none of this. He devotes just about a whole chapter to music in China, but says absolutely nothing about the grass-roots live music scene that is ubiquitous in America, still the largest market in the world. Put together a Leontief input-output model (hardcore economics again -- I got to study and work a little with Nobel winner Leontief back in the day) of the club scene, showing how music radiates out into various areas of the economy via tourism, food service, transportation, fashion, etc., and this is a huge, possibly dominant segment of the industry that gets no attention in this book.
I have one other problem with the superstar model. My older daughter was in youth theater, went to college for drama, and my younger daughter was an elite youth soccer player, now playing in college. Their dreams were winning Oscars and Olympic gold. But the more realistic goal was easier to envision -- all their teachers, coaches, trainers, choreographers, etc., their dream was Oscar and gold too, but they found productive lives within the economy in their areas of greatest passion at other levels. There is more to the music industry than U2, Springsteen, and Taylor Swift. So much more that the superstar model actually fails, except at the tabloid level where a high school drama teacher and club soccer coach aren't going to compete with Bruno Mars.
Nevertheless, there is much to like about Rockonomics. I especially like the sidebar interviews with industry players. And I like that much of the analysis was backed up by empirical evidence and not just anecdotal evidence -- although the anecdotes are a lot fun anyway. There is a high probability that my critique is unique to me -- and yet, none of my critiques diminish what is here, I only wish there was more. Hopefully there are economists out there ready to build on what Krueger has started.
