Copyright Protection, Technological Change, and the Quality of New Products: Evidence from Recorded

Music since Napster

AND

And the Bands Played On: Digital Disintermediation and the Quality of New

Recorded Music

Intro – assuring flow of creative works

• Appropriability – may beget creative works

– depends on both law and technology

• IP rights are monopolies granted to provide incentives for creation – Harms and benefits

• Recent technological changes may have altered the balance – First, file sharing makes it harder to appropriate revenue…

…and revenue has plunged

Ensuing Research

• Mostly a kerfuffle about whether file sharing cannibalizes sales

• Oberholzer-Gee and Strumpf (2006),Rob and Waldfogel (2006), Blackburn (2004), Zentner (2006), and more

• Most believe that file sharing reduces sales

• …and this has led to calls for strengthening IP protection

My Epiphany

• Revenue reduction, interesting for producers, is not the most interesting question

• Instead: will flow of new products continue?

• We should worry about both consumers and producers

Industry view: the sky is falling

• IFPI: “Music is an investment-intensive business… Very few sectors have a comparable proportion of sales to R&D investment to the music industry.”

• Warner Music: “…piracy makes it more difficult for the whole industry to sustain that regular investment in breaking talent.”

• RIAA: “Our goal with all these anti-piracy efforts is to protect the ability of the recording industry to invest in new bands and new music…”

• RIAA: “this theft has hurt the music community, with thousands of layoffs, songwriters out of work and new artists having a harder time getting signed and breaking into the business.”

File sharing is not the only innovation

• “Compound experiment” – Costs of production, promotion, and distribution

may also have fallen

– Maybe weaker IP protection is enough

• My empirical question: What has happened to the “quality” of new products since Napster? – Contribute to an evidence-based discussion on

adequacy of IP protection in new economy

• And if so, why?

Hard problem

• Quantifying the volume of high-quality new music released over time is hard

• Some obvious candidates are non-starters

– # works released (but skew)

– # works selling > X copies (moving target)

Two Broad Approaches

• Quality index based on critics’ best-of lists

• 2 indices based on vintage service flow

– Airplay by time and vintage

– Sales by time and vintage

Approach #1: critics’ lists

• Want index of the number of works released each year surpassing a constant threshold

• Use critics’ retrospective best-of lists

– E.g. Number of albums on a best-of-the-decade list from each year

– Retrospective: to be on list, album’s quality must exceed a constant threshold

Index Availability

Data Validity

• Do indices pick up major eras?

– Larkin (2007): “The 60s will remain, probably forever, the single most important decade for popular music.”

• Do indices track each other?

• Are critical responses relevant to demand (and therefore economic welfare)?

Album Year Dummies and Napster

Index is falling prior to Napster

Post-Napster constancy is, if anything, a relative increase

Answer #1

• No reduction in quality following Napster

– Cf “The sky is falling.”

• But:

– Elites

– Right tail

– Not consumption data

Approach #2

• Measure of vintage “quality” based on service flow/consumer decision

– Sales and airplay

• Idea: if one vintage’s music is “better” than another’s, its greater appeal should generate higher sales or greater airplay through time, after accounting for depreciation

Data: Airplay

• (Describing data first makes empirical approach easier to exposit)

• For 2004-2008, observe the annual share of aired songs originally released in each prior year.

• From Mediaguide

– 2000, over 1 million spins/year

– Lots of data: smooth, precise

Vintage Distribution for Songs Aired in 2008

Direct evidence of depreciation

Data: Sales

• Coarse sales data: RIAA certifications

– See when sales pass thresholds, know when released

• Gold=0.5 million, Platinum=1 million, multi-platinum=X million – Apportion uniformly

• 17,935 album certs; 4428 single certs

• Covers most of music sales

• Tracks known patterns

• Eliminate greatest hits

Depreciation in Sales Data

• Again, older albums sell less

• Question: after accounting for music age, are particular vintages sold, aired more? Or less?

Distribution of Sales by Time since Release

Regression approach

• Define st,v = share of vintage v music in the sales or airplay of music in period t. – Observe s for V vintages and T years – For a given year t, s varies across vintages for two

reasons • Depreciation and variation in vintage quality

• Regress ln(st,v) on age dummies, vintage dummies. – Allow flexible depreciation pattern

• Then: vintage dummies are index of vintage “quality”

Bottom line

• No evidence that vintage quality has declined

• Some evidence that it has increased

• Hard to know what it might otherwise have been

• Puzzle: Why is “quality” up despite revenue collapse?

And the Bands Played On: Digital Disintermediation and the Quality of New Recorded Music

Joel Waldfogel

University of Minnesota and NBER

Fundamental features of recorded music

• “nobody knows” (Caves) – Hard to predict success at time of investment

– Perhaps 10 percent succeed

• Traditionally, it has been expensive to “experiment” (Tervio) – Must bring a product to market to learn whether it

will succeed

– ≈$1 million using traditional means

– So bet on a few artists with ex ante promise • Result: “mediocrity”

Along comes digitization

• (…and demand: piracy)

• …and supply – Obvious effects on production and distribution

• Recording, distribution are now inexpensive

– Promotion too? • Traditionally, radio is a bottleneck

• Now Internet radio and online criticism

• It has become cheaper to “experiment” – Do we end up discovering more artists with ex post

value?

Plan for Act II

• “model” rationalizing increased quality

• Questions

• Data

• Results

“Model” inspired by Caves(“nobody knows”) and Tervio (“mediocrity”)

• Label forms estimate of album marketability q’ as truth + error: q’=q + ϵ

• Bring a product to market if q’> T.

• Cost reduction trumps piracy, so that on balance, digitization reduces T, raising the number of projects that can be brought to market.

• Big question: what happens to the volume of “good” work available to consumers?

Suppose marketability were predictable

• Then reduction in T brings more products

• But they are of modest quality: T’ < q < T

With unpredictability

• Release all products with expected quality above T’

• Result: more products with quality > T

• Release of products with less ex ante promise leads to a greater number of products with ex post success/value

Is this explanation right? Some specific empirical questions

• More new products?

• …including those with less ex ante promise?

– E.g. independent vs major labels

• A changed information/promotion environment?

– Do consumers have ways to learn about the proliferation of new music?

Questions

• Changed paths to commercial success?

– Roles of tradition radio, Internet, and critics

• Is sales concentration rising or falling?

– Do additional products draw share?

• Do the products with less ex ante promise – e.g. indie artists who would not have been released before digitization – account for a rising share of ex post success?

Illustrative Anecdote: Arcade Fire’s The Suburbs

• Released by indie Merge Records August, 3, 2011

• Critical acclaim – Metascore=87 (top 5%)

• Little conventional airplay – Not on BB Airplay Chart

– But big on Internet radio

• Success – Sold >0.5 million copies

– Best Album Grammy for 2011 1

Arcade Fire – Ready to Start on Last.fm

On to more systematic evidence: Two Broad Data Sets

• Albums released in the US 1980-2010 – By label type

• major, independent, self-released

– Physical vs digital

• list of commercially successful albums – from top-selling album charts

• (and my estimates of the albums’ actual sales)

– linked with • measures of traditional radio airplay • promotion on Internet radio • coverage by music critics • whether on independent label

…from 9 underlying sources

• Recordings

– Discogs, 1980-2011

• Albums (including vinyl, CD, “files”)

• Singles excluded

• Hand-matching of labels to label codes from Thomson (2010) – Plus… “underground”, “independent”,…

Commercially successful albums

• Billboard 200 – weekly ranking of top 200 selling albums, 1985-2011

• Heatseekers – weekly top 50 albums by emerging artists (2000-2011)

• Billboard Independent album chart – 2001-2011

– Use for independent designation in dataset 2

Promotion

• Airplay – Billboard 100 – 75 top songs of the week, 1990-

2011

– Top 200 airplay – 2009-2011

– Last.fm – top 420 songs of the week, 2006-2011

• Critics – Metacritic – coverage if 3+ critics review

– Appeared in 2000; growth to roughly 1000 albums per year in 2010

Sales Certifications

• RIAA – Gold, Platinum database

– 1970-2010

– I use to translate BB album rankings into sales estimates

– But only about 300 distinct artists

• Traditional vs Internet radio

– Compare BB list with last.fm top 420 songs of the week

Evolution of sales concentration

• More products available

• Do more products achieve (relative) commercial success?

– Do more albums enter the weekly BB200?

– Not the dumb question it sounds like

• 200 listings/week x 52 weeks = 10,400 listings/year

• Could be anywhere between 200 and 10,400 distinct artists per year

Sales grow less concentrated in top few artists

Conclusion

• Despite revenue reduction, “quality” is up

• Digital disintermediation provides possible explanation for increased “quality”

• Given unpredictability, more “experimentation” leads to discovery of additional “good” music

• Much of which would not have come to market before digitization
