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
Target
ActualttBAI
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 ConnectionsAt 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?

Compute q*, V*, then scroll through quantities up to qv=0. We compute V at each quantity then compute weights.
Do so in 10 percentage point intervals, so we have a 11x11 matrix of wi’s.

Econometric Implementation
Data on What is Purchased? How much is Paid? Demographics of Buyers Cost data by modality
BAI can be computed using this data Example provided in Paper No. 36
Target Setting
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.

Residual Actual Fitted
Nearly all (93%) of the differences in fixed connections per capita across countries are explained by few demographic and economic endowments.
Summary
Performance is a value-based conceptAny 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
