A laboratory experiment studies coordination and cooperation in games played in different networks - local, random and small-world. Coordination on the payoff-dominant equilibrium was faster in small-world networks than in local and random networks. However, in a prisoner's dilemma game,...

We embed an experiment in a large-scale representative survey to investigate how relative wealth affects risk-taking and how this effect varies as a function of perceived control over life outcomes. Our results contest the common prediction of higher risk-taking in the middle of the...

Does the ability to pledge an asset as collateral, after purchase, affect its price? This paper identifies the impact of collateral service flows on house prices, exploiting a plausibly exogenous constitutional amendment in Texas which legalized home equity loans in 1998. The law change...
