We report data from an online experiment, which allow us to study whether generosity has changed during the early Covid-19 pandemic. We have gathered data from Spanish participants over a six-day period in which Covid-19-associated deaths in Spain, one of the most affected countries, increased...

Prenatal exposure to hormones, and to sex hormones in particular, exerts organizational effects on the brain and these have observable behavioral correlates in adult life. There are reasons to expect that social behaviors—which are fundamental for the evolutionary success of humans—might be...

This paper explores excuse-driven behavior in giving. In our powered laboratory experiment, participants play Dictator Games sharing 5e or 1,000e under certainty or ambiguity with a charity. In contrast to previous papers using MPLs {that necessarily introduce additional layers of...

Numerous studies in management, sociology, and economics have documented that the architecture of collaboration networks affects the innovation performance of individuals, firms, and regions. Little is known though about whether the association between collaboration patterns and innovation...

Humans differ greatly in their tendency to discount future events, but the reasons underlying such inter-individual differences remain poorly understood. The evolutionary framework of Life History Theory predicts that the extent to which individuals discount the future should be influenced by...

We study experimentally the impact of pre-play social interactions on negotiations. We isolate the impact of several common components of interactions: conversations, food, and alcoholic or non-alcoholic beverages. Participants perform a standardized negotiation (complex and simple) under six...

Measuring risk preferences in the field is critical for policy, however, it can be expensive and may generate unequal payoffs due to bad luck. For instance, the commonly used measure of Holt and Laury (2002) relies on a dozen of lottery choices and payments which makes it time consuming and...

The use of hypothetical instead of real decision-making incentives remains under debate after decades of economic experiments. Standard incentivized experiments involve substantial monetary costs due to participants’ earnings and often logistic costs as well. In time preferences experiments,...
