The unconditional expectation of social welfare is often used to assess alternative macroeconomic policy rules in applied quantative research. It is shown that it is generally possible to derive a linear-quadratic problem that approximates the exact non-linear porblem where the unconditional...

In 2007, countries in the euro periphery were enjoying stable growth, low deficits and low spreads. Then the financial crisis erupted and pushed them into deep recession, raising their deficits and debt levels. By 2010, they were facing severe debt problems. Spreads increased and, surprisingly,...

Global imbalances and financial market (de)regulation both feature prominently among the potential causes of the global financial crisis, but they have been generally discussed separately. In this paper, we take a different angle and investigate the relationship between financial market...

International Macroeconomics has long sought an explanation for current account fluctuations that matches the data. The approaches have typically focused on better models and new macroeconomic variables. We demonstrate the limitations of this approach by showing that idiosyncratic shocks are an...

In this paper we re-examine the long standing and puzzling correlation between national savings and investment in industrial countries. We apply an econometric methodology that allows us to separate idiosyncratic correlation at the country level from correlation at the global level. In a major...

Extending Gali and Monacelli (2004 ), we build an N-country open economy model, where each economy is subject to sticky wages and prices and, potentially, has access to sales and income taxes as well as government spending as fiscal instruments. We examine an economy either as a small open...

We study simple fiscal rules for stabilizing the government debt level in response to asymmetric demand shocks in a country that belongs to a currency union. We compare debt stabilization through tax rate adjustments with debt stabilization through expenditure changes. While rapid and flexible...

This paper develops a two-country DSGE model for a monetary union in which each country is populated by two types of households - savers and borrowers - and two types of production sectors - a consumption goods sector and a housing sector. Households trade nominal private debt in equilibrium,...
