We report an experiment examining risk taking and information aggregation in groups. Group members come to the table with an individual preference for a choice under risk, based on privately received information, and can share this information with fellow group members. They then make a decision...

We investigate experimentally the effect of consultation (unincentivized advice) on choices under risk in an incentivized investment task. We compare consultation to two benchmark treatments: one with isolated individual choices, and a second with group choice after communication. Our benchmark...

We report a controlled laboratory experiment examining risk-taking and information aggregation in groups facing a common risk. The experiment allows us to examine how subjects respond to new information, in the form of both privately observed signals and signals reported from others. We find...

Using an experiment with incentivized decisions of groups in the economics laboratory, I investigate the effect of group diversity on group risk taking. I measure econometrically the effects of various aspects of subjects' diversity: nationality, language, university degree and gender. I find...

Salient social comparisons to peers are generally thought to increase people's productive effort. But social comparisons can also become ends in themselves, with individuals seeking to outrank others by costly, non-productive means. This paper explores the motives behind such tendencies in the...

We develop a screening model to analyse the funding allocation criteria of institutional donors towards NGOs. The model shows that when donors care about efficiency, they screen NGOs and concentrate their funding on those that comply. Combining two waves, 2002 and 2008, of a unique survey data...

We introduce endogenous fire sales into a simple network model. For any given initial distribution of shocks across the network, we develop a clearing algorithm to solve for the financial equilibrium. We then utilise the results to perform ex ante risk assessment and derive risk premia for every...

We introduce a banking sector and heterogeneous agents in the Matsuyama et al. (2016) dynamic over-lapping generations neoclassical model with good and bad projects. The model captures the benefits and costs of an advanced banking system which can facilitate economic development when allocates...

Charitable giving has increasingly become ‘tough love’ - it has come to require recipients to undertake costly prior action. A common justification is that of greater efficiency: willingness to undertake costly actions signals greater productivity from transfers. However, there is a...
