In this paper, we measure the welfare costs/gains associated with financial market incompleteness in a monetary union. To do this, we build on a two-country model of a monetary union with sticky prices subject to asymmetric productivity shocks. For most plausible values of price stickiness, we...

We analyze the effects of world wars on the macroeconomic dynamics of the U.S., France, Germany, and the UK, by means of an estimated open-economy model. The model allows wars to affect the economy through capital depreciation, sovereign default, a military draft, household preferences, and...

Following the Great Recession, U.S. government debt levels exceeded 100% of output. We develop a macroeconomic model to evaluate the role of various shocks during and after the Great Recession; labor market shocks have the greatest impact on macroeconomic activity. We then evaluate the...

We develop a two-country model with an explicitly microfounded interbank market and sovereign default risk. Calibrated to the core and the periphery of the Euro Area, the model gives rise to a debt-banks-credit loop that substantially amplifies the effects of financial shocks, especially for the...

This paper explores the relationship between exchange rate adjustment and trade policy in a simple New Keynesian open economy macro model. We show that movement in exchange rates have a direct implication for trade policy when governments choose tariffs endogenously. In particular, we show that...

In this paper, we propose a theoretical framework to investigate the impact of conflicts and wars on key macroeconomic aggregates and welfare. Using a panel data with 9 countries from 1870 onwards, we first show that the consumption-to-output ratio is minimal during WWII for participants. While...

We show that welfare can be lower under complete financial markets than under autarky in a monetary union with home bias, sticky prices and asymmetric shocks. Such a monetary union is a second-best environment in which the structure of financial markets affects risk-sharing but also shapes the...

Recent financial crises in Europe as well as the periodic battles in the U.S. over the debt ceiling point to the importance of fiscal discipline among developed countries. This paper develops an open economy model, calibrated to the U.S. and a subset of the EMU, to evaluate the impact of various...

This paper examines if taking into account changes in the number of producers, or equivalently changes in the product variety space over the business cycle, helps to understand and replicate international business cycle facts. To this end, we develop a two-country model in which the economy is...
