GEORGE FORD CHIEF ECONOMIST THE PHOENIX CENTER July 15, 2009 National Press Club The Broadband Adoption Index: Policy Paper No. 36
Create an economically meaningful and policy relevant index of broadband adoption that also is capable of handling heterogeneous connection modalities (e.g. fixed and mobile).
If the $7B achieves universal availability over the next few years, the U.S. will probably not change rank.
General Form Goal: 1.Provide for meaningful performance evaluation across geo-political units (intra- and internationally). 2.Incorporate the underlying economics of adoption and deployment 3.Accommodate different connection modalities
Population is not a Target Population is not a target of adoption as implied by OECD statistics In the U.S., telephones were ubiquitously available and nearly universally adopted, yet TEL/POP was only 0.493. In Sweden, it was the same, but their TEL/POP was 0.686.

Other Issues with OECD-Style Metric Today, it includes only Fixed Connections At the request of a few countries, OECD now plans to collect and report mobile broadband in the near future. Broadband = 256kbps or more Counted if you buy it or use it (in a specified interval of time) But how is the data to be used as a measure of adoption performance?
OECD Style Index Fixed = Fixed/Population ? Index Mobile = Mobile/Population ? How do you rank across 2 dimensions? Can we just add the two for a single index? Do we get the SIM card problem for Europe? What about countries that do mostly one and hardly any of the other? What if the count is high but due to some having multiple connections rather than many having at least one form of connection? How do we deal with the fact that fixed is typically shared, mobile is often not (scaling problem).
How to Combine the Two? Can we just add: Fixed + Mobile Fixed is mostly shared, Mobile is mostly consumed by individuals Mobile counts will swamp fixed counts Should we scale Fixed by the share rate Fixed + Mobile/ShareRate (sharerate may be hh size) Assumes Mobile is a low quality fixed How do homogenize unlike things? We convert the counts to values What is the value of fixed? What is the value of mobile?
One Modality v i * = average social value of a connection of modality i at the target q i * = quantity of connections of modality i at the target
What is the Value of Broadband? Willingness to Pay (w) Social Premia (e) Externalities Spillovers Etc. Cost of Production (c) Net Social Value v = w + e - c
Maximum Subscription is Not Ideal As long as c - e > 0, 100% consumption is not ideal. w c- e $ q*q* A q v=0 W Welfare Loss from excess consumption. qi*qi* q i v=0 V i * V i v=0 ViVi Social Value (V) Social Value = A - B
Optimal Consumption Depends on Costs If costs are higher, then optimal quantity is lower. w c- e $ q*q* w $ q*q* q Low Cost Market High Cost Market q
Optimal Consumption Depends on Demand If demand is lower, then optimal quantity is lower. w c- e $ q*q* w $ q*q* High Demand Market Low Demand Market q q
Simple Graph w c - e $ q*q* Avg. Value = v* = V/q* Soc. Value = v*q* = V q V
BAI at Time t Assumption: Marginal, thus average, valuation declines over time. Here, highest valued users adopt first. w cici $ q*q* q1q1 A B C q v=0
Simulation Two Modalities, f and m f is shared m is personal c f =40; c m = 20 Max value for m is 100 Average share rate: k = 2 Scale f demand to 200 (= 100·2) Personal Market = 2,000 persons Shared Market = 1,000 units (= 2,000/k) m is a mild net substitute for f
Simulation Algorithm cici vivi qiqi qi*qi* q i v=0 Compute q *, V *, then scroll through quantities up to q v=0. We compute V at each quantity then compute weights. Do so in 10 percentage point intervals, so we have a 11 x 11 matrix of w i s.
Some Portugal Targets Achieve at least 50% household broadband adoption. Increase public access to public Internet locations (16 per 100 POP). Increase number of computers in schools to one per five students. 100% of Central Government institutions with broadband access. 100% of hospitals with broadband access.
Target Setting It is unreasonable to expect a relatively poor and uneducated country to have the same broadband deployment and adoption rates as a relatively rich and educated country. Comparing such countries on per-capita terms says nothing about the success or failure of broadband policies. 50% adoption in Mexico or Turkey may be stellar, but in the U.S. would be considered a failure.

Summary Performance is a value-based concept Any modality that generates value must be included in performance measures Per- Capita Normalizations are misguided Anyway, not clear how to do it with multiple modalities Combining heterogeneous modalities is tricky, but the problem is understood The underlying economics of deployment and adoption must be considered for good policy Countries vary in their demand and cost profiles Maximal deployment/adoption assumes external effects are enormous
Summary Avoid the willy-nilly by focusing the analysis on the components of target setting Willingness to Pay Realistic size of the Social Premia Cost of deployment
