Optimal Stabilization Policy with Search Externalities
نویسندگان
چکیده
We study optimal monetary stabilization policy in a DSGE model with microfounded money demand. A search externality creates ‘congestion’ which causes aggregate output to be inefficient. Due to the informational frictions that give rise to money, households are unable to perfectly insure themselves against aggregate shocks. This gives rise to a welfare improving role for monetary policy that works by adjusting the nominal interest rate in response to these shocks. Optimal policy is determined by choosing a set of state-contingent nominal interest rates to maximize the expected lifetime utility of the agents subject to the constraints of being an equilibrium.

Flexible inflation targeting and labor market inefficiencies☆
a r t i c l e i n f o Do congestion externalities offer a reason to depart from complete price stability as the only goal of monetary policy in a New Keynesian model featuring search frictions, and under what conditions is the welfare cost of labor-market distortions sizable? This paper tries to answer these questions by deriving a linear quadratic framework for optimal monetary policy analysis...
متن کاملOptimal Unemployment Insurance in a Matching Equilibrium: The Role of Congestion and Thick-Market Externalities
This paper characterises optimal unemployment insurance (UI) and optimal tax policy in an equilibrium matching framework where job search effort is unobserved by the Planner. Policy design takes into account congestion externalities (greater job search effort by an individual worker reduces the re-employment rate of other competing job seekers) and thick market externalities (greater job creati...
متن کاملTransport , health and climate change : Deciding on the optimal policy *
Transport generates many externalities, some related to atmospheric pollution. In this paper, we focus on two: greenhouse gases, and local pollution. In the search for optimal transport policies, these two externalities have usually been analysed separately. Here, we study them jointly, in a sequential decision-making model. Our model allows for the irreversibility of the policies undertaken, a...

متن کاملOptimal Policy with Heterogeneous Preferences
Optimal policy rules—including those regarding income taxation, commodity taxation, public goods, and externalities—are typically derived in models with homogeneous preferences. This article reconsiders many central results for the case in which preferences for commodities, public goods, and externalities are heterogeneous. When preference differences are observable, standard second-best result...
