We investigate experimentally the effect of consultation (unincentivized advice) on choices
under risk in an incentivized investment task. We compare consultation to two benchmark …

We conducted a set of experiments to compare the effect of ambiguity in single-person
decisions and games. Our results suggest that ambiguity has a bigger impact in games than …

The success of new technologies such as contact tracing mobile applications depends on
large-scale end-user adoption. However, the implementation may encounter resistance …

Tip** points can occur in many complex environmental systems and often produce abrupt
and irreversible change. Thresholds associated with tip** points are difficult to predict in …

This paper examines the difference between strategic ambiguity as in game theory and
ambiguity arising in individual decisions. We identify a new, non-strategic component …

We study the behavioral drivers of market entry. An experiment allows us to disentangle the
impact on entry across different types of markets of two key behavioral mechanisms …

Most decision-making research in economics focuses on individual decisions. Yet, we know,
from psychological research in particular, that individual preferences can be sensitive to …

This paper studies temporal-distance effects on individual and social risks, testing Construal

In laboratory experiments we explore the effects of communication and group decision
making on investment behavior and on subjects' proneness to behavioral biases. Most …
