Two key issues are examined in an integrated framework: the emergence of global imbalances and the precautionary motive for accumulating reserves. Standard models of general equilibrium would predict modest current account surpluses in the emerging markets if they face higher risk than the US...

In 2009 the Australian government delivered approximately $8 billion in direct payments to households. These payments were preannounced and randomly allocated to households based on postal codes over a 5-week period. We exploit this random allocation to estimate the causal response of...

Government spending at the zero lower bound (ZLB) is not necessarily welfare enhancing, even when its output multiplier is large. When government spending provides direct utility to the household, its optimal level is at most 0.5-1 percent of GDP for recessions of -4 percent; the numbers are...

Almost half of American families did not adjust their consumption following receipt of the 2001 or 2008 tax rebates. Another 20%, with low income and more likely to rent, spent a small but significant amount. Households with large spending propensity held high mortgage debt. The heterogeneity is...

Foreign exchange windfalls such as those from natural resource revenues change non-resource exports, imports, and the capital account. We study the balance between these responses and, using data on 41 resource exporters for 1970-2006, show that the response to a dollar of resource revenue is,...

We study the joint dynamics of foreign capital flows and real activity during the recent boom-bust cycle of the Spanish economy, using a three-country New Keynesian model with credit constrained households and firms, a construction sector and a government. We estimate the model using...

What is the impact of surprise and anticipated policy changes when agents form expectations using adaptive learning rather than rational expectations? We examine this issue using the standard stochastic real business cycle model with lump-sum taxes. Agents combine knowledge about future policy...

We study a largely neglected channel through which government expenditures boost private consumption. We set up a lifecycle model in which households are subject to health shocks. We estimate a negative impact of public health care on household consumption dispersion, wealth and saving....

This paper provides new evidence on the effects of fiscal policy by studying, using household-level data, how households respond to shifts in government spending. Our identification strategy allows us to control for time-specific aggregate effects, such as the stance of monetary policy or the...
