The evidence for the United States points to balanced growth despite falling investment-good prices and an elasticity of substitution between capital and labor less than one. This is inconsistent with the Uzawa Growth Theorem. We extend Uzawa's theorem to show that the introduction of human...

This paper proposes a tractable and realistic nonlinear model of exchange rate dynamics, and argues that its predictions are consistent with available empirical evidence on exchange rate and interest differential behavior in real-life target zones. In our model, the exchange rate fluctuates...

The paper argues that the reason real world fixed exchange rate regimes usually have finite bands instead of completely fixed exchange rates between realignments is that exchange rate bands, counter to the textbook result, give central banks some monetary independence, even with free...

The paper reviews the recent literature on exchange rate target zones and on speculative attacks on fixed exchange rates. The influential Krugman model of exchange rate target zones has two main results, namely that credible target zones stabilize exchange rates more than fundamentals (the...

The foreign exchange risk premium in an exchange rate target zone regime with devaluation/realignment risks is derived. In contrast to previous literature, the exchange rate's heteroscedasticity within the bard, as well as a separate devaluation/realignment risk, is taken into account. The risk...

The term structure of interest rate differentials is derived in a model of a small open economy with a target zone exchange rate regime. The target zone is modeled as a regulated Brownian motion. The interest rate differentials are computed as the solution to a parabolic partial differential...

We examine the expected survival time of a unilateral exchange rate target zone, when constraints on monetary policy prevent the central bank from exclusively focusing on defending the target zone. Generally, the width of the target zone has a negligible effect on the expected survival time, and...

Stabilization programs in open economies typically consist of two stages. In the first stage the rate of currency devaluation is reduced, but the fiscal adjustment does not eliminate the fiscal deficit which causes growth of debt and loss of reserves, making a future policy change necessary....

We study the politics of intergenerational redistribution in an overlapping generations model with short-lived governments. The successive governmentsþwho care about the welfare of the currently living generations and possibly about campaign contributionsþare unable to pre-commit the future...

Existing proposals to escape from a liquidity trap and deflation, including my Foolproof Way,' are discussed in the light of the optimal way to escape. The optimal way involves three elements: (1) an explicit central-bank commitment to a higher future price level; (2) a concrete action that...
