Abstract:
Survey data show that the expected growth rates of consumption across countries vary widely and are not highly correlated. This data contradicts the simplest of open-economy models in which there is a freely traded non- state-contingent bond and purchasing power parity holds. We explore two alternative explanations for the finding: that households in each country in effect face different ex ante real interest rates or that there are significant credit constraints, so that expected consumption growth rates are driven largely by expected income growth. The empirical evidence strongly supports the latter hypothesis. These findings challenge the modeling of consumption that is at the heart of many, if not most, macroeconomic models.

2. The U.S. Current Account Deficit and the Expected Share of World Output

Abstract:
We investigate the possibility that the large current account deficits of the U.S. are the outcome of optimizing behavior. We develop a simple long-run world equilibrium model in which a country's current account is determined by the expected discounted present value of its future share of world GDP relative to its current share of world GDP. The model suggests that under some reasonable assumptions about future U.S. GDP growth relative to the rest of the advanced countries – more modest than the growth over the past 20 years – the current account deficit is near optimal levels. We then explore the implications for the real exchange rate. Under some plausible assumptions, the model implies little change in the real exchange rate over the adjustment path, though the conclusion is sensitive to assumptions about tastes and technology. Then we turn to empirical evidence. Two empirical analyses of current account sustainability using actual data suggest that the U.S. is not keeping on a long-run sustainable path. One is a direct test of our model, which finds that the dynamics of the U.S. current account – the increasing deficits over the past decade – are difficult to explain under a particular statistical model (Markov-switching) of expectations of future U.S. growth. But, if we use survey data on forecasted GDP growth in the G7, our very simple model appears to explain the evolution of the U.S. current account remarkably well. We conclude that expectations of robust performance of the U.S. economy relative to the rest of the advanced countries is a contender – though not the only legitimate contender – for explaining the U.S. current account deficit.
