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...

Eurozone is going though the worst ever crises since the adoption of the common currency in 1999. In the aftermath of financial crises of 2007, many EU government due to their own fragile banking system and imbalance economic structures persued a debt-spending financing which resulted into a...

This paper offers a framework to study commitment and cooperation issues in games with multiple policymakers. To reconcile some puzzles in the recent literature on the nature of policy interactions among nations, we prove that games characterized by different commitment and cooperation schemes...

This paper explores links between global financial imbalances and tensions around reserve currency along with climate change. Currently, risky levels of private and public debts co-exist with vast amounts of savings which "do not know where to go." Long-term climate-oriented financial products...

This paper analyzes the long-run effect of monetary policy when credit constraints are taken into account. This analysis is carried on in a heterogeneous agents framework in which infinitely lived agents can partially self-insure against income risks by using both financial assets and real...

In this paper, we study the equilibrium dynamics of an overlapping generations model with capital, money and cash-in-advance constraints. At each period, the economy can experience two different regimes: either the cash-inadvance constraint is binding and money is a dominated asset, or the...

In this paper, we investigate the impact of monetary policy signals stemming from the ECB Council and the FOMC on the intradaily Euro-dollar volatility, using high-frequency data (five minutes frequency). For that, we estimate an AR(1)-GARCH(1,1) model, which integrates a polynomials structure...

In this article, we examine the intradaily Euro-dollar exchange rate volatility persistence result from the dissymmetric impact of monetary policy signals stemming from the ECB Council and the FOMC. A model is constructed by extending the AR(1)-GARCH (1,1) to an exponential process EGARCH (1,1),...

The recent sovereign debt crisis in Europe, now a Eurozone crisis, has prompted a growing awareness of the disparities in the economic conditions and competitive positions of Eurozone countries. Such disparities are reflected in the accumulation of imbalances to the disadvantage of countries in...

This paper investigates the relevance of the No-Ponzi game condition for public debt (i.e. the public debt growth rates has to be lower than the real interest rate, a necessary assumption for Ricardian equivalence) and of the transversality condition for the GDP growth rate (i.e. the GDP growth...
