We study the Ramsey (1928) model under the assumption that households act strategically. We compute the Markov perfect equilib- rium for this model and compare it to the original, competitive equi- librium and to a strategic open-loop equilibrium proposed by Sorger (2002, 2005b). We show that,...

We describe a simple mechanism that generates inflation persistence in a standard sticky-price model of optimal fiscal and monetary policy. Key to this mechanism is that policies are implemented under discretion. The government's discretionary incentive to erode the real value of nominal public...

We describe a simple mechanism that generates inflation persistence in a standard sticky-price model of optimal fiscal and monetary policy. Key to this mechanism is that policies are decided under discretion. The government's discretionary incentive to erode the real value of nominal public debt...

We study the delegation of climate policy to a supranational environmental authority. We demonstrate that the authority faces a dynamic inconsistency problem that leads to welfare losses. The losses can be kept small if the mandate of the authority penalizes the local cost of emissions heavily,...

We examine the dynamic properties of inflation in a model of optimal discretionary fiscal and monetary policies. The lack of commitment and the presence of nominally risk-free debt provide the government with an incentive to implement policies which induce positive and persistent inflation...

This paper studies optimal fiscal and monetary policy in a stochastic economy with imperfectly competitive product markets and a discretionary government. We find that, in the flexible price economy, optimal time-consistent policy implements the Friedman rule independently of the degree of...

We study the monetary instrument problem in a model of optimal discretionary fiscal and monetary policy. The policy problem is cast as a dynamic game between the central bank, the fiscal authority, and the private sector. We show that, as long as there is a conflict of interest between the two...

We study Markov-perfect Nash equilibria (MPNE) of a Ramsey-Cass-Koopmans economy in which households are aware of their influence on prices. The Ramsey conjecture fails to hold such that households other than the most patient one own positive wealth in the steady state. This confirms results...
