This note derives the dynamic programming equation (DPE) to a differentiable Markov Perfect equilibrium in a problem with non-constant discounting and general functional forms. We begin with a discrete stage model and take the limit as the length of the stage goes to 0 to obtain the DPE...

The use of a constant discount rate to study long-lived environmental problems such as global warming has two disadvantages: the prescribed policy is sensitive to the discount rate, and with moderate discount rates, large future damages have almost no effect on current decisions. Time-consistent...

From the classical gold standard up to the current ERM2 arrangement of the European Union, target zones have been a widely used exchange regime in contemporary history. This paper presents a benchmark model that rationalizes the choice of target zones over the rest of regimes: the fixed rate,...

Recent attempts to incorporate optimal fiscal policy into New Keynesian models subject to nominal inertia, have tended to assume that policy makers are benevolent and have access to a commitment technology. A separate literature, on the New Political Economy, has focused on real economies where...

Cellini and Lambertini endogenize through a timing game the moves of the central bank and the private sector in a model of monetary policy la Barro and Gordon. They find a multiplicity of equilibria, as the two Stackelberg outcomes emerge as the solutions of the timing game, with different...

Building on models of electoral competition with reputational mechanisms, I show that term limits decrease the vote share of candidates from parties less able to reward or punish candidates. Candidates suffer by not being able to credibly commit to policies far from their own preferences....

We model an innovator's choice of payment scheme and duration as a joint decision in a multi-period licensing game with potential future innovations and some irreversibility of technology transfer. We find that it may be optimal to license the innovation for less than the full length of the...

We examine solutions in which neither player is worse off from the leadership of one in a policy maker-public game. The loop model of dynamic games is used. Outcome space is dotted with equivalence classes of solutions. The Dynamic Stochastic General Equilibrium (DSGE) results and their New...

Since the signing of the Maastricht Treaty, there has been an intensive discussion whether the convergence criteria incorporated into the contract were appropriate to prepare the EU-member-countries for European Monetary Union. We argue that at least inflationary convergence was not a necessary...

Using dynamic programming methodology, the paper analyzes the most general conditions for an additive utility functional to represent time consistent preferences. It challenges the conventional wisdom of the domain, which, following Strotz(1956), assume that only exponential discounting is...
