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.

Coal-fired power plants may enjoy a significant advantage relative to gas plants in terms of cheaper fuel cost. Still, this advantage may erode or even turn into disadvantage depending on CO2 emission allowance price. This price will presumably rise in both the Kyoto Protocol commitment period...

Stochastic relative preferences are prevalent in the literature, but it appears that modeling them is not trivial. This paper establishes that common stochastic specifications alter average relative preferences, which could induce spurious effects. A simple solution is presented that provides an...

Many studies show that most people are not financially literate and are unfamiliar with even the most basic economic concepts. However, the evidence on the determinants of economic literacy is scant. This paper uses international panel data on 55 countries, merging indicators of economic...
