Recently, Amazon released lists of its 100 top selling new
titles for 2014. Last year, I analyzed
the 2013 list, so this year I will do the same.
I will also compare and contrast the two lists, to see what has changed
from then until now.
In this blog, I will be looking at apparent pricing
strategies, as revealed by the prices listed for books in the Amazon Top 100
for the two years. First a few notes on
the listed prices:
·
In late 2013, when I first recorded the data for
the Amazon Top 100 for 2013, I used the prices shown on the list on the Amazon
website. I printed the list on Dec 16,
2013, so prices for those books are indicative of that point in time.
·
I revisited that list a few days ago, about Jan
20, 2015. I recorded the prices shown on
that list at that point in time. I also
recorded the “click-through” price, that showed up when one went to the
specific book in question. There were
some interesting differences in all these numbers.
·
For the 2014 data, I recorded both the list
price and the “click-through” price.
Again, there were some interesting differences.
·
I assume that the “list prices” represent some
representative price for the book throughout the year, while the Jan 20 “click
through” price was the price set at that particular time. Many of these had the notation “Price Set by
Publisher”. More often than not, the
price set by publisher price on that date was higher than the list price. I don’t know the details, but I presume it
represents recent price increases by publishers, after re-negotiating their
supplier deals with Amazon.
This blog will primarily address the price changes in the
Top 100 lists, from 2013 to 2014, using the “list prices”.
Overall Price
Changes
The average listed price in the Amazon Top 100 Kindle books
in 2013 was $6.06, while it was $6.58 in 2014, an increase of $0.52 or 9%. The graph below shows the change in price
at each rank in the Top 100 from 2013 to 2014.
The sloped line shows the general trend.
As you can see, there was a tendency for prices to go up in the first
half of the Top 100 and down in the latter half. But there is a lot of noise in the data.
Note that the big spike in the last part of the graph is due
to Thomas Piketty’s economics book “Capital in the 21st Century”,
which was very popular, considering its price and subject matter. As you
can see, that sort of thing doesn’t happen very often (though publishers must
love it, when it does).
Regrouping the data by decile (tenths of the dataset) makes
the trend more obvious, as the table and graph below show.

So, it seems clear that there has been a change in pricing
strategy between 2013 and 2014. Books in
the top half of the list were up by a couple of bucks on average, while those
in the bottom half were down by about a buck.
The decile view shows that this was quasi-linear (kind of a straight
line) throughout the range.
Some Interesting
Sub-Analyses
In the analyses that follow, I will tend to stick to graphs
and R-Squares to explain the findings.
R-square values show how well the data conforms to the functional
relationship being tested – in this case that will always be straight lines
(linear relationships). I will use the
decile graphs (10 bars) – they present a nice compromise between the excessive
noise of the full ranking comparisons (100 bars) and the over generality of the
quartile groupings (4 bars).
Trads vs Indies: If we look at the decile graphs by publisher
type, we see something interesting – this is very much a traditional publishing
strategy (Trad R-square=.60, Indie=.28).
Note that I took the Piketty book out of the data, as it flips the last
decile bar for Trad from negative to positive, which misrepresents the overall
effect.

Genre: Using
the five genre categories below, the table shows the R-Square of the linear
effect of decile on price. The closer
that number is to 1, the greater the effect.
The nearer to 0, the lesser the effect.

So, in sum, for the Amazon Top 100:
·
Ebook prices have been raised from 2013 to 2014
on average by about 9% overall.
·
But the books in the top half of the list have
had their prices raised by considerably more than this, and the books in the
bottom half of the list have had price drops.
·
This effect is seen primarily in traditionally
published books – the trend is much less evident for Indie books, though there
might be some slight tendency that way.
·
Romance, Thrillers and Literary Fiction have
been the main targets of this approach, Romance especially so.
·
As noted earlier, the effect of this strategy
has been to bin books into highly priced books versus low priced books. The number of books in the mid-range price
range has been reduced in favor of this highly stratified approach.
So, what is an Indie to make of this? One could look at it and say:
- Higher prices overall, for Trad books opens up room for Indies to compete, generally speaking.
- But Trads are also hitting the lower price ranges, harder than they did in the past, crowding that part of the market with more of their product.
- So, perhaps that opens up the mid-range for higher quality independent books.
As always, though, strategies and responses to competitor
strategies are highly debatable.
