We provide a preference-based rationale for endogenous overconfidence. Horizon-dependent risk aversion, combined with a possibility to forget, can generate overconfidence and excessive risk taking in equilibrium. An "anxiety prone" agent, who is more risk-averse to imminent than to distant...

We experimentally test overconfidence in investment decisions by offering participants the possibility to substitute their own for alternative investment choices. Overall, 149 subjects participated in two experiments, one with just one risky asset, the other with two risky assets. Overconfidence...

Narrow bracketing in combination with loss aversion has been shown to reduce individual risk-taking. This is known as myopic loss aversion (MLA) and has been corroborated by many studies. Recent evidence has contested this notion indicating that MLA's applicability is confined to highly...

This paper tests how subjects behave in an intertemporal consumption/saving experiment when borrowing is allowed and whether subjects treat debt differently than savings. Two treatments create environments where either saving or borrowing is required for optimal consumption. Since both...

We report a portfolio-choice experiment that enables us to estimate parametric models of ambiguity aversion at the level of the individual subject. The assets are Arrow securities that correspond to three states of nature, where one state is risky with known probability and two states are...

In this article, a simple paper-and-pencil experiment, based on lottery bonds, shows that financial decisions taken by participants are inconsistent with the traditional view of economic agents as risk averse expected utility maximizers. First, our results cast doubt on the relevance of variance...

This paper analyzes the stability and distribution of ambiguity attitudes using a broad population sample. Using high-powered incentives, we collected six waves of data on ambiguity attitudes about financial markets-our main application-and climate change. Estimating a structural stochastic...
