This paper proposes a theory of the fiscal foundations of inflation based on imperfect knowledge and learning. The theory is similar in spirit to, but distinct from, unpleasant monetarist arithmetic and the fiscal theory of the price level. Because the assumption of imperfect knowledge breaks...

I give necessary and sufficient conditions under which interest-rate feedback rules eliminate aggregate instability by inducing a globally unique optimal equilibrium in a canonical New Keynesian economy with a binding zero lower bound. I consider a central bank that initially keeps interest...

We propose a new interest rate rule that implements the optimal equilibrium and eliminates all indeterminacy in a canonical New Keynesian model in which the zero lower bound on nominal interest rates (ZLB) is binding. The rule commits to zero nominal interest rates for a length of time that...

"This paper explores the effects of central bank transparency on the performance of optimal inflation targeting rules. I assume that both the central bank and the private sector face uncertainty about the "correct" model of the economy and have to learn. A transparent central bank can reduce one...

This paper compares the properties of interest rate rules such as simple Taylor rules and rules that respond to price-level fluctuations - called Wicksellian rules - in a basic forward-looking model. By introducing appropriate history dependence in policy, Wicksellian rules perform better than...

The adoption of quantitative easing (QE) policy by the United States (US) Federal Reserve Bank since early 2009 has aroused widespread concerns in Asia and elsewhere regarding its possible impact in terms of the weakening of the US dollar and stimulating capital outflows to emerging economies...

This paper investigates the consequences of debt stabilization for inflation targeting. If the monetary authority perfectly stabilizes inflation while the fiscal authority holds constant the real value of debt at maturity, the equilibrium dynamics might be indeterminate. However, determinacy can...

We develop a new set of indexes of exchange rate stability, monetary policy independence, and financial market openness as the metrics for the trilemma hypothesis. In our exploration, we take a different and more nuanced approach than the previous indexes developed by Aizenman, Chinn, and Ito...
