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 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...

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...

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...

Abstract: The economies of the six Gulf Cooperation Council (GCC) countries are heavily reliant on oil. Greater economic diversification would reduce their exposure to volatility and uncertainty in the global oil market, help create jobs in the private sector, increase productivity and...

The more a country saves, the less it invests as a share of saving. We build a “store-or-sow” model of growth with precautionary saving and investment to study the nonlinear relationship between investment and saving. We contend that income volatility is an important variable for explaining...

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...
