Semi-Annual Economic Update:

Our frame of reference is complex adaptive systems theory, in which a system can be operating in a stable, adaptive, or chaotic region, depending on the amount of tension exhibited by key variables. Our thesis is that many of these variables are at levels that have pushed the global political-economic-financial system into the adaptive region. It is also our thesis that many of these uncertainties are approaching their next critical threshold, which could push the system into the chaotic zone.

At the domestic level, these variables include the unresolved conflicts between "tax payers and tax eaters" in Western developed countries, between the old and new guard in Japan, between growth and stability in China, and between young, rapidly growing populations and inflexible political and religious structures in the Arab world. At the international level, critical tensions include the response to the United States' dominant power, the accelerating emergence of China, severely unbalanced world demand growth, and the continuing economic and financial ramifications of the 1990s technology shock.
