We consider a multi-sector general equilibrium model with IO linkages, sector-specific productivities and tax rates. Using tools from network theory, we investigate how the IO structure interacts with productivities and taxes in the determination of aggregate income. We show that aggregate...

This paper explores the transmission of non-capital shocks through banking networks. We develop a methodology to construct non-capital (idiosyncratic) shocks, using labor productivity shocks to large firms. We document a change in the relationship between foreign idiosyncratic shocks and...

Proxy structural vector autoregressions (SVARs)identify structural shocks in vector autoregressions (VARs) with external proxy variables that are correlated with the structural shocks of interest but uncorrelated with other structural shocks. We provide asymptotic theory for proxy SVARs when the...

When is it optimal for a government to default on its legal repayment oblig- ations? We answer this question for a small open economy with domestic production risk in which the government optimally finances itself by issuing non-contingent debt. We show that Ramsey optimal policies occasionally...
