When the zero lower bound on nominal interest rates binds, monetary policy cannot provide appropriate stimulus. We show that in the standard New Keynesian model, tax policy can deliver such stimulus at no cost and in a time-consistent manner. There is no need to use inefficient policies such as...

How much of carry trade excess returns can be explained by the presence of disaster risk? To answer this question, we propose a simple structural model that includes both Gaussian and disaster risk premia and can be estimated even in samples that do not contain disasters. The model points to a...

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 and...

The Paper highlights one critical difference between Europe and the US regarding the Phillips curve: the behaviour of prices. While they are quickly restored to an equilibrium level in the US, European prices are driven by highly counter-cyclical mark-ups. In bad times, European firms manage to...

We propose a new model of exchange rates, based on the hypothesis that the possibility of rare but extreme disasters is an important determinant of risk premia in asset markets. The probability of world disasters as well as each country's exposure to these events is time-varying. This creates...

We show that even when the exchange rate cannot be devalued, a small set of conventional fiscal instruments can robustly replicate the real allocations attained under a nominal exchange rate devaluation in a standard New Keynesian open economy environment. We perform the analysis under...

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. Our story goes as follows:...

This paper seeks to bridge the gap between economists focused on designing competitive market mechanisms and engineers focused on the physical attributes and engineering requirements they perceive as being needed for operating a reliable electric power system. The paper starts by deriving the...

This paper empirically explores standard-setting organizations’ policy choices. Consistent with Lerner-Tirole (2006), we find (a) a negative relationship between the extent to which an SSO is oriented to technology sponsors and the concession level required of sponsors and (b) a positive...

The paper first develops an economic analysis of the concept of shareholder value, describes its approach and discusses some open questions. It emphasizes the relationship between pledgeable income, monitoring and control rights using a unifying and simple framework. The paper then provides a...
