Orthodox and heterodox theories of financial crises are hereby compared from a theoretical viewpoint, with emphasis on their genesis. The former view (represented by the fourth generation models of Paul Krugman) reflects the neoclassical vision whereby turbulence is an exception; the latter...

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...

I adapt the framework of Sauzet (2021) to an international setting to characterize the global solution to the international portfolio problem in full generality, a long-standing open issue in international finance. In this two-country, two-good environment, investors have recursive preferences...

I study the joint dynamics between the US wealth share, the dollar and the global economy. I uncover three novel stylised facts about these joint dynamics. Firstly, the US wealth share is countercyclical: it falls on impact but subsequently rises over the course of global recessions. Secondly...

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 United States (US) extracts a large macroeconomic premium from foreigners: she enjoys higher consumption and GDP growths on average relative to the rest of the world (ROW). This is earned even though the US is relatively insulated against global consumption and GDP risks, challenging a...

This paper reviews reassesses the methodology and principal findings of the “Rose effect”, i.e. the trade effects of currency union, looking at both EMU and non-EMU currency unions. The consensus estimate suggests that the euro has already boosted intra-euro area trade by five to ten...

Flexible labor markets require geographically mobile workers to be efficient. Otherwise, firms can take advantage of the immobility of workers and extract monopsony rents. In cultures with strong family ties, moving away from home is costly. Thus, individuals with strong family ties rationally...

Recent empirical and theoretical literature on the impact of real exchange rate devaluations on economic performance questions the traditional expansionary effect generated within standard Mundell-Fleming models. Contractionary devaluations may arise when firms face maturity or currency...
