This paper considers some of the main risks and opportunities currently facing the world economy. Against a baseline forecast of October 2009, it first discusses a number of policy mistakes or policy failures that could lead to even worse outcomes than currently envisaged. It then describes the...

We study the welfare properties of a New Keynesian monetary economy with an essential role for risky bank lending. Banks lend funds deposited by households to a financial accelerator sector, and face penalties for maintaining insufficient net worth. The loan contract specifies an unconditional...

We study the welfare properties of an economy where both monetary and fiscal policies follow simple rules, and where a subset of agents is liquidity constrained. The welfare benefits of optimizing the fiscal rule are far larger than those of optimizing the monetary rule. The optimized fiscal...

The paper studies how high leverage and crises can arise as a result of changes in the income distribution. Empirically, the periods 1920-1929 and 1983-2008 both exhibited a large increase in the income share of the rich, a large increase in leverage for the remainder, and an eventual financial...

The paper studies how high leverage and crises can arise as a result of changes in the income distribution. Empirically, the periods 1920-1929 and 1983-2007 both exhibited a large increase in the income share of the rich, a large increase in leverage for the remainder, and an eventual financial...

For thirty years prominent voices have advocated a policy of starving the beast cutting taxes to force government spending cuts. This paper analyzes the macroeconomic and welfare consequences of this policy using a two-country general equilibrium model. Under several strong assumptions the...

The IMF's Global Integrated Monetary and Fiscal Model is used to compute short-run multipliers of fiscal stimulus measures and long-run crowding-out effects of higher debt. Multipliers of two-year stimulus range from 0.2 to 2.2 depending on the fiscal instrument, the extent of monetary...

The paper evaluates the costs and benefits of fiscal consolidation using simulations based on the IMFs global dynamic general equilibrium model GIMF. Over the longer run, well-targeted permanent reductions in budget deficits can lead to a considerable increase in both the growth rate and the...

The paper analyzes Chile’s structural surplus fiscal rule in the face of shocks to the world copper price. Two results are obtained. First, Chile’s current fiscal rule performs well if the policymaker (i) puts a premium on avoiding excessive volatility in fiscal instruments, and (ii) puts a...
