This paper studies optimal monetary policy under dynamic debt deleveraging once the zero bound is binding. Unlike the existing literature, the natural rate of interest is endogenous and depends on macroeconomic policy. Optimal monetary policy successfully raises the natural rate of interest by...

This paper examines the optimal response of monetary and fiscal policy to a decline in aggregate demand. The theoretical framework is a two-period general equilibrium model in which prices are sticky in the short run and flexible in the long run. Policy is evaluated by how well it raises the...

We propose an overlapping generations New Keynesian model in which a permanent (or very persistent) slump is possible without any self-correcting force to full employment. The trigger for the slump is a deleveraging shock, which creates an oversupply of savings. Other forces that work in the...

This paper proposes a theory to explain why a politician delegates policy tasks to a technocrat in an independent institution. It formalizes the rationales for delegation highlighted by Hamilton (1788) and by Blinder (1998). Delegation trades-off the cost of having a possibly incompetent...

Can government policies that increase the monopoly power of firms and the militancy of unions increase output? This paper shows that the answer is yes under certain "emergency" conditions. These emergency conditions--zero interest rates and deflation--were satisfied during the Great Depression...

This paper analyzes the effectiveness of fiscal policy at zero nominal interest rates. I solve a stochastic general equilibrium model with sticky prices assuming that the government cannot commit to future policy. Real government spending increases demand by boosting public consumption. Deficit...

This paper outlines a simple Bayesian methodology for estimating tax and spending multipliers in a dynamic stochastic general equilibrium (DSGE) model. After forming priors about the parameters of the model and the relevant shock, we used the model to exactly match only one data point: the...

Tax cuts can deepen a recession if the short-term nominal interest rate is zero, according to a standard New Keynesian business cycle model. An example of a contractionary tax cut is a reduction in taxes on wages. This tax cut deepens a recession because it increases deflationary pressures....
