This paper explores the consequences of extremely low real interest rates in a world with integrated but heterogenous capital markets and nominal rigidities. We establish four main results: (i) Liquidity traps spread to the rest of the world through the current account, which we illustrate with...

The secular decline in safe interest rates since the early 1980s has been the subject of considerable attention. In this short paper, we argue that it is important to consider the evolution of safe real rates in conjunction with three other first-order macroeconomic stylized facts: the relative...

We explore the consequences of safe asset scarcity on aggregate demand in a stylized IS-LM/Mundell Fleming environment. Acute safe asset scarcity forces the economy into a “safety trap” recession. In the open economy, safe asset scarcity spreads from one country to the other via capital...

In this paper we argue that the persistent global imbalances, the subprime crisis, and the volatile oil and asset prices that followed it, are tightly interconnected. They all stem from a global environment where sound and liquid financial assets are in scarce supply

Three of the most important recent facts in global macroeconomics -- the sustained rise in the US current account deficit, the stubborn decline in long run real rates, and the rise in the share of US assets in global portfolio -- appear as anomalies from the perspective of conventional wisdom...

This paper explores the consequences of extremely low equilibrium real interest rates in a world with integrated but heterogenous capital markets and nominal rigidities. In this context, we establish five main results: (i) Economies experiencing liquidity traps pull others into a similar...

We explore the consequences of safe asset scarcity on aggregate demand in a stylized IS-LM/Mundell Fleming environment. Acute safe asset scarcity forces the economy into a "safety trap" recession. In the open economy, safe asset scarcity spreads from one country to the other via capital flows,...
