When risks are interdependent, an agent's decision to self-protect affects the loss probabilities faced by others. Due to these externalities, economic agents invest too little in prevention relative to the socially efficient level by ignoring marginal external costs or benefits conferred on...

Theequivalence holds if the representative household maximizes utility while taking pricesparametrically. This result justifies TFP...

Firms select not only how many, but also which workers to hire. Yet, in standard searchmodels of the labor market, all workers have the same probability of being hired. We arguethat selective hiring crucially affects welfare analysis. Our model is isomorphic to a searchmodel under random hiring...
