Entropy Economics

In testimony before Congress’s Joint Economic Committee today, Fed chairman Ben Bernanke noted that

In contrast to the somewhat better news in the household sector, the available indicators of business investment remain extremely weak.

But it is these key business sectors that are most important for a U.S. — and global — economic recovery. As important as stabilization of the housing sector is, we are not going to be led out of the recession by another housing boom. Nor should we desire that. We need real productivity-enhancing innovation, which is largely enabled by non-real estate investment and entrepreneurship.

Among the myriad policy actions being taken in Washington this year is a potential overhaul of our communications strategy, under the aegis of the FCC’s new Broadband “Notice of Inquiry.” The first goal of this plan should be to to encourage the continued investment in leading-edge information technologies. Broadband communications especially makes all our businesses in every sector more productive and also connects an ever larger number of citizens, especially those who may be struggling the most in this tough economy, to the wider world, improving their prospects for education, health, and new jobs in emerging industries.

Information and communications technology (ICT) accounts for an astounding 43% of non-structure U.S. capital investment, totaling $455 billion 2008. In this new FCC communications policy review, we should do everything possible to keep this huge source of American growth rolling. Any policy obstacles thrown into the path of our information industries would not only reduce this crucial component of absolute capital investment, which is already under strain, but also diminish and delay all the positive cascading follow-on effects of a more networked workforce and world.

Lots of commentators continue to misinterpret the research I and others have done on Internet traffic and its interplay with network infrastructure investment and communications policy.

I think that new video applications require lots more bandwidth — and, equally or even more important, that more bandwidth drives creative new applications. Two sides of the innovation coin. And I think investment friendly policies are necessary both to encourage deployment of new wireline and wireless broadband and also boost innovative new applications and services for consumers and businesses.

But this article, as one of many examples, mis-summarizes my view. It uses scary words like “apocalypse,” “catastrophe,” and, well, “scare mongering,” to describe my optimistic anticipation of an exaflood of Internet innovations coming our way. I don’t think that

the world will simply run out of bandwidth and we’ll all be weeping over our clogged tubes.

Not unless we block the expansion of new network capacity and capability. Read the rest of this entry »

The supposed top finding of a new report commissioned by the British telecom regulator Ofcom is that we won’t need any QoS (quality of service) or traffic management to accommodate next generation video services, which are driving Internet traffic at consistently high annual growth rates of between 50% and 60%. TelecomTV One headlined, “Much ado about nothing: Internet CAN take video strain says UK study.” 

But the content of the Analysys Mason (AM) study, entitled “Delivering High Quality Video Services Online,” does not support either (1) the media headline — “Much ado about nothing,” which implies next generation services and brisk traffic growth don’t require much in the way of new technology or new investment to accommodate them — or (2) its own “finding” that QoS and traffic management aren’t needed to deliver these next generation content and services.

For example, AM acknowledges in one of its five key findings in the Executive Summary:

innovative business models might be limited by regulation: if the ability to develop and deploy novel approaches was limited by new regulation, this might limit the potential for growth in online video services.

In fact, the very first key finding says:

A delay in the migration to [British Telecom’s next generation] 21CN-based bitstream products may have a negative impact on service providers that use current bitstream products, as growth in consumption of video services could be held back due to the prohibitive costs of backhaul capacity to support them on the legacy core network. We believe that the timely migration to 21CN will be important in enabling significant take-up of online video services at prices that are reasonable for consumers.

So very large investments in new technologies and platforms are needed, and new regulations that discourage this investment could delay crucial innovations on the edge. Sounds like much ado about something, something very big. Read the rest of this entry »
