Oil exporters have run large current account surpluses. We explore oil exporters' role in our understanding and the resolution of global imbalances. Current account dynamics are estimated for oil-exporting countries and the rest of the world. We find that fiscal policy has a much stronger effect...

We study how macroeconomic shocks affect U.S. public debt dynamics using a VAR with debt feedback. Following a fiscal austerity shock, the debt ratio initially declines and then returns to its pre-shock path. Yet, the effect is not statistically significant. In a weak economic environment, the...

We study the effects of permanent and temporary income shocks on precautionary saving and investment in a ""store-or-sow"" model of growth. High volatility of permanent shocks results in high precautionary saving in the safe asset and low investment, or a ""volatility trap."" Namely, big savers...

Policymakers in oil-exporting countries confront the question of how to allocate oil revenues among consumption, saving, and investment in the face of high income volatility. We study this allocation problem in a precautionary saving and investment model under uncertainty. Consistent with data...

A key priority for the Gulf Cooperation Council (GCC) countries is to create a dynamic non-oil tradable sector to support sustainable growth. Since export diversification takes a long time, it has to start now. We argue that the failure to diversify away from oil stems mainly from market...

Industrial policies pursued in many developing countries in the 1950s-1970s largely failed while the industrial policies of the Asian Miracles succeeded. We argue that a key factor of success is industrial policy with export orientation in contrast to import substitution. Exporting encouraged...

We investigate the effect of R&D subsidies on firms' innovation by ownership, industry, and firm size using German firm-level data. The impact of R&D subsidies is heterogeneous across industries for multinational corporations (MNCs) and domestic firms while it does not differ substantially by...
