This paper analyzes an economy in which agents face related problems and invest in parameter information that they share. The N-player game generates growth via statistical learning alone. The equilibrium growth rate rises with agents' risk aversion via precautionary saving. Research entails a free riding problem, but the scale effect dominates and growth rises with the number of agents. (Copyright: Elsevier)
