Optimal unemployment policy in a matching equilibrium

This paper considers optimal unemployment policy in a matching equilibrium with risk averse workers and unobserved job search effort. The Planner chooses unemployment benefits, taxes and job creation subsidies to maximise a Utilitarian welfare function. Optimal policy involves a trade-off between higher employment taxes (which finance more generous unemployment benefits) and greater market tightness (which reduces the average unemployment spell). Optimal UI implies the initial UI payment equals the wage, thus ensuring consumption is smooth across the job destruction shock, and UI payments then fall with duration.
