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 present a unified dynamic framework to study the interconnections between international trade and business cycle models. We prove an aggregate equivalence between a competitive, representative firm model that has aggregate production externalities and dynamic trade models that feature...

We study aggregate, distributional, and welfare effects of a permanent reduction in the capital tax rate in a quantitative model with capital-skill complementarity and household heterogeneity. Such a tax reform leads to expansionary long-run aggregate output and investment effects, but those are...

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 study the implications of increased price flexibility on output volatility. In a simple DSGE model, we show analytically that more flexible prices always amplify output volatility for supply shocks and also amplify output volatility for demand shocks if monetary policy does not respond...

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,...

We study the implications of increased price flexibility on aggregate output volatility in a dynamic stochastic general equilibrium (DSGE) model. First, using a simplified version of the model, we show analytically that the results depend on the shocks driving the economy and the systematic...
