Optimal growth and uncertainty: Learning
We introduce learning in a Brock-Mirman environment and study the effect of risk generated by the planner’s econometric activity on optimal consumption and investment. Here, learning introduces two sources of risk about future payoffs: structural uncertainty and uncertainty from the anticipation of learning. The latter renders control and learning nonseparable. We present two sets of results in...
متن کاملUncertainty and Learning
It is a commonplace in statistics that uncertainty about parameters drives learning. Indeed one of the most influential models of behavioural learning has uncertainty at its heart. However, many popular theoretical models of learning focus exclusively on error, and ignore uncertainty. Here we review the links between learning and uncertainty from three perspectives: statistical theories such as...

Uncertainty, Volatility, and Growth Rate
This paper examines two related models, which permit analytical investigation, to gain some insights into a relationship between endogenous growth and business cycle. Using two simple models which incorporate Fisher Black’s idea that a significant part of business cycle fluctuations is a consequence of an economy’s choice, we obtained a negative relationship between uncertainty and growth. Henc...
متن کاملUncertainty-Induced Reallocations and Growth
Focusing on U.S. data, we show the existence of a significant positive link between uncertainty and reallocation from private to government capital. This link is important because an increase in the aggregate share of government capital forecasts lower medium-term growth. We rationalize these novel empirical findings in a production economy in which the representative agent has an explicit fear...
