This paper makes three contributions. First, I construct annual time series of gross domestic investment and national saving in the United States for the 1897-1949 period using historical component series. I compare the qualitative and quantitative properties of the newly constructed series with...

In recent years, a number of studies have analyzed the experiences of a broad range of industrial economies during periods when their current account deficits have narrowed. Such studies identified systematic aspects of external adjustment, but it is unclear how good a guide the experience of...

From 1960-2009, the U.S. current account balance has tended to decline during expansions and improve in recessions. We argue that trend shocks to productivity can help explain the countercyclical U.S. current account. Our framework is a two-country, two-good real business cycle (RBC) model in...

A central puzzle in international finance is that real exchange rates are volatile and, in stark contradiction to effcient risk-sharing, negatively correlated with cross-country consumption ratios. This paper shows that incomplete asset markets and a low price elasticity of tradables can account...

Gianluca Benigno examines the extent to which the financial crisis has undermined the dollar's pre-eminence.

In an analytically tractable model of the global economy, we calculate the Pareto improvement where a country experiencing a favourable supply side shock consumes more against expected future output and spreads the risk by selling shares. With capital inflows to finance the ‘New Economy’...

The influential work of Obstfeld and Rogoff argues that a closing-up of the US current account deficit involves a large exchange rate adjustment. However, the Obstfeld-Rogoff model works exclusively via demand-side channels and abstracts from possible supply-side changes. We extend the framework...

Since the late-1990s, the global economy is characterised by historically low risk premia and an unprecedented widening of external imbalances. This paper explores to what extent these two global trends can be understood as a reaction to three structural shocks in different regions of the global...

We use a quantitative equilibrium model with houses, collateralized debt, and foreign borrowing to study the impact of global imbalances on the U.S. economy in the 2000s. Our results suggest that the dynamics of foreign capital flows account for between one-fourth and one-third of the increase...

In the canonical monetary policy model, money is endogenous to the optimal path for interest rates and output. But when liquidity provision by banks dominates the demand for transactions money from the real economy, money is likely to contain information for future output and inflation because...
