Appointments more than double testing rates, with effects concentrated among those who demand commitment. In contrast, most men who take up hard commitments l...

摘要：We experimentally study effort provision and network formation in the linear-quadratic game characterised by positive externality and complementarity of effort choices among network neighbours. We compare experimental outcomes to the equilibrium and efficient allocations and study the impact of group size and linking costs. We find that individuals overprovide effort relative to the equilibrium level on the network they form. However, their payoffs are lower than the equilibrium payoffs becaus...
