We analyse belief formation in social networks in a laboratory experiment. Our 3 x 3 design varies the network structure and the amount of information agents have about it. Agents observe an imperfect private signal on the true state of the world and then repeatedly guess the true state,...

We develop a theory and perform an experiment to study the effect of performance thresholds on effort and risk-taking in economic decisions. We find that effort unambiguously increases compared to the ``status quo" level, but that optimal effort varies non monotonically with the threshold level....

Focusing on decisions in health and finance, we collected new data in a general population survey on (i) individual-specific attitudes toward risk, loss and ambiguity and (ii) individual-specific probabilistic beliefs about events related to the decisions we consider. The joint availability of...

We investigate the potential of diversity to influence committee decision-making. We present a model in which committee members receive private information on a state of the world, deliberate and vote. Committee members belong to one of two groups which may differ along two dimensions: (a) their...

Many Social Interactions display either or both of the following well documented phenomena. People tend to interact with similar others (homophily). And they tend to treat others more favorably if they are perceived to share the same identity (in-group bias). While both phenomena involve some...

We study extrapolation between games in a laboratory experiment. Participants in our experiment first play either the dominance solvable guessing game or a Coordination version of the guessing game for five rounds. Afterwards they play a 3x3 normal form game for ten rounds with random matching...

Using personnel and analytics data from over 10,000 skilled professionals at a large Asian IT services company, we compare productivity before and during the work from home [WFH] period of the Covid-19 pandemic. Total hours worked increased by roughly 30%, including a rise of 18% in working...
