We show that, when a central bank is not fully financially backed by the treasury and faces a solvency constraint, an increase in the size or a change in the composition of it's balance sheet (quantitative easing) can serve as a commitment device in a liquidity trap scenario. In particular, when...

We investigate open economy dimensions of optimal monetary and fiscal policy at the zero lower bound (ZLB) in a small open economy model. At positive interest rates, the trade elasticity has negligible effects on optimal policy. In contrast, at the ZLB, the trade elasticity plays a key role in...

We estimate international spillover effects of US Quantitative Easing (QE) on emerging market economies. Using a Bayesian VAR on monthly US macroeconomic and financial data, we first identify the US QE shock with non-recursive identifying restrictions. We estimate strong and robust macroeconomic...

We study international spillover effects of US monetary policy. We use monthly panel data from fifteen major emerging market economies (EMEs), in a period where the countries have a flexible exchange rate regime and are integrated into global financial markets. We show that US monetary policy...

We estimate international spillover effects of the United States (US)' Quantitative Easing (QE) on emerging market economies (EMEs). Using a Bayesian VAR on monthly US macroeconomic and financial data, we first identify the US QE shock. The identified US QE shock is then used in a monthly...

We derive closed-form solutions and sufficient statistics for inflation and GDP dynamics in multi-sector New Keynesian economies with arbitrary input-output linkages. Analytically, we decompose how production linkages (1) amplify the persistence of inflation and GDP responses to monetary and...

We show that the effectiveness of redistribution policy is tied to how much inflation it generates, and thereby to monetary‐fiscal adjustments that ultimately finance the transfers. In the monetary regime, taxes increase to finance transfers while in the fiscal regime, inflation rises,...
