This paper explores the relationship between the self-declared risk aversion of private investors and their propensity to hold incomplete portfolios of financial assets. The analysis is based on household survey data from the German Socioeconomic Panel (SOEP) that provides a reliable measure of...

We study portfolio diversification in an experimental decision task, where asset returns depend on a draw from an ambiguous urn. Holding other information identical and controlling for the level of ambiguity, we find that labeling assets as being familiar or from the homeland of subjects...

Empirical evidences show that investors tend to be biased toward investing in domestic (home bias) and local (local bias) stocks. Familiarity is considered to be one of the reasons. A similar concept was proposed by Goldstein and Gigerenzer (1999, 2002), known as the recognition heuristic: "when...

We provide the first tests to distinguish whether individual investors equally balance their overall portfolios (naïve portfolio diversification—NPD) or engage in naïve buying diversification (NBD)—equally balancing values in same-day purchases of multiple assets. We find NBD in purchases...

We document that prior portfolio choices influence investors' expectations about asset values, and their future choices. We find that people update more from information consistent with their prior choices, leading to sticky portfolios over time. These effects are related to how the brain's...

What can studying the creation of knowledge tell us about how new technical fields emerge and develop? This paper shows how a knowledge community may be necessary to support the legitimacy of new products that undergo performance evaluation before purchase. Using historical and ethnographic data...

We hypothesize the existence of a slow-moving fad component in art prices. Using unique panel survey data on art market participants' confidence levels in the outlook for a set of artists, we find that sentiment indeed predicts short-term returns

Financial disclosure documents provide investors with product details to facilitate informed investment decisions. We investigate whether the appearance - the visual frame - of disclosure documents impacts risk and return expectations and investment behavior. In our experiment, subjects decide...
