We study the representative consumer's risk attitude and efficient risk-sharing rules in a single-period, single-good economy in which consumers have homogeneous probabilistic beliefs but heterogeneous risk attitudes. We prove that if all consumers have convex absolute risk tolerance, so must...

This paper explores the optimal consumption and investment behavior of an individual who derives utility from the ratio between his consumption and an endogenous habit. We obtain closed-form policies under general utility functionals and stochastic investment opportunities, by developing a...

Economists have become increasingly interested in using attention to explain behavioral patterns both on the micro and macro level. This has resulted in several disparate theoretical approaches. Some, like rational inattention, assume a "top-down" model of executive optimization. Others, like...

Customizing the optimal derivative written on an “instrument” risk to hedge an exogenous pecuniary risk is only examined in a few works assuming specific objective function and/or distribution of the risks. We show that this problem is closely-related to a previously un-examined...

We analytically show that a common across rich/poor individuals Stone-Geary utility function with subsistence consumption in the context of a simple two-asset portfolio-choice model is capable of qualitatively and quantitatively explaining: (i) the higher saving rates of the rich, (ii) the...

Combining recent empirical findings on the usefulness of financial literacy for investment decisions and literature from psychology, we argue that the behavior of people with a high level of financial literacy might depend on the prevalence of the two thinking styles according to dual-process...

The central role of the media for people's minds and for capital markets has been analyzed by a broad range of literature, nourished from several strands of academic research. Applying a vector autoregression on a unique set of TV news, consumer sentiment and excess flows of mutual funds, I find...
