Free-market true believers will resist the conclusion, but the only way to preserve a global growthmodelbased on the huge benefits of dynamic markets is to regulate it better.
Working with NCI statistician Richard Simon, Norton came up with a new model of tumor growthbased on the work of the 19th-century mathematician Benjamin Gompertz.
His choice marks him as an apologist for the model itself, and makes his belief in growth (apparently based on sound arguments) something of an article of faith.
But some economists stress that the focus on consumption as a measure of economic growth can be misleading, arguing that a model that is not based on production cannot be sustainable.
His model is based on factors such as changes in bank lending, the economic growth rate and the size of the speculative-grade market (a glut of issuance tends to be an indicator of loose lending practices).
The Forbes survey found that companies that use the outcome-based approach are more innovative, and not surprisingly, that this model tends to have a positive impact on growth.
