Digital Renaissance
Joel Waldfogel
University of Minnesota and NBER
CREATe Conference, February 4, 2015
Introduction
• Digitization and media industries: a two-part
story
– Bad news on demand side
• Napster, BitTorrent, etc
– Cost reduction on supply side
• Reduced costs of production, distribution, promotion
• …along with “nobody knows” effect
• Revolutionary effects on recorded music, books,
movies, television,…
– Lots of new products, many of which are
consequential
My additional goals today
• While piracy is interesting/important, we should
focus more research energy on whether the
supply of new products remains robust
• Rethink which evidence addresses whether
copyright is fulfilling its function
• Are we experiencing a crisis?
– Evidence on music, books, movies, & television
• Copyright research needs more and better data
– Data availability woes necessitate flexibility
Outline
• Music quality since Napster: rising or falling?
• Why?
• Then revisit the relevant questions in book,
motion picture, and other creative sectors
• …in the order of the evolution of my
understanding
Digitization in music, round 1
• The standard music paper motivation since
’99: “the sky is falling!”

Research Response
• Mostly a kerfuffle about whether file sharing
cannibalizes sales
• Surprisingly hard question to answer
» Oberholzer-Gee and Strumpf (2006),Rob and Waldfogel
(2006), Blackburn (2004), Zentner (2006), and more
• …but most believe that file sharing reduces
sales
My Epiphany
• Revenue reduction, interesting for producers, is not the
most important question
• Instead: will flow of new products continue?
– (We should worry about both consumers and producers)
• RIAA, IFPI: reduced investment will lead to an audio
stone age
File sharing is not the only innovation
• “Compound experiment”
– Costs of production, promotion, and distribution
have also fallen
– Maybe weaker IP protection is enough
• 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
Hard problem: assessing
quality/service flow of work over time
• 2 approaches:
• Critics’ 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
• Usage information by time and vintage

anything, a

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 2004-2008 by vintage
• Sales 1970-2010, by vintage
– From RIAA certifications
Regression approach
• Define st,v = share of vintage v music in the
sales or airplay of music in period t.
– For a given year t, s varies across vintages because
of 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
• More compelling evidence that it has
increased
• Hard to know what it might otherwise have
been
• Big contrast to IFPI/RIAA view
• Puzzle: why continued quality despite revenue
collapse?
Fundamental features of creative products
• “nobody knows anything” (Caves/Goldman)
– 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
– Music: ≈$1 million using traditional means
– So bet on a few artists with ex ante promise
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?
How could quality improve?
“Model” inspired by Goldman (“nobody knows”)
• 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?
Four questions:
• More new products?
– …including “indies” with less ex ante promise?
• Do consumers have ways to learn about a
proliferation of new products?
– Changing roles of traditional radio, Internet, and
critics
Four questions, cont’d
• 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%)
• Success
– Sold >0.5 million copies
– Best Album Grammy for 2011

Changing Information Environment
• Traditional radio
– BB airplay – top 75 songs by week
• 3,900 listings per year
– But only about 300 distinct artists
• Traditional vs Internet radio
– Compare BB list with last.fm top 420 songs of the
week in 2006
– Little overlap – 10 percent

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

would earlier not
have existed – take

Summing up music
• Digital disintermediation provides possible
explanation for increased “quality”
• Given unpredictability, more
“experimentation” leads to discovery of
additional “good” music
– Ex ante loser become ex post winners
• Much of which would not have come to
market before digitization
What about other cultural products?
• Books, motion pictures, television,…
• Of each, ask the questions (when possible):
– More products?
– Ways to learn about new products?
– Changing sales concentration
– Growing success of ex ante “losers”?
– Are the new vintages “good”?
Books
• Growth in new products, “ecosystem”?

• Production
– Digital cameras that are cheap and good
• Distribution
– Digital sales (iTunes, Netflix, Amazon,…)
• Promotion
– Lots of movies reviewed online + user-generated

• ….raising the possibility of 1) new movies that 2)
might be discovered by, and of interest to,
