In this paper we propose a novel way to model the labor market in the context of a New-Keynesian general equilibrium model, incorporating labor market frictions in the form of hiring and firing costs. We show that such a model is able to replicate many important stylized facts of the business...

It is common knowledge that the standard New Keynesian model is not able to generate a persistent response in output to temporary monetary shocks. We show that this shortcoming can be remedied in a simple and intuitively appealing way through the introduction of labor turnover costs (such as...

Using a standard dynamic general equilibrium model, we show that the interaction of staggered nominal contracts with hyperbolic discounting leads to inflation having significant long-run effects on real variables.

The Friedman rule states that steady-state welfare is maximized when there is deflation at the real rate of interest. Recent work by Khan et al (2003) uses a richer model but still finds deflation optimal. In an otherwise standard new Keynesian model we show that, if households have hyperbolic...

The paper studies the macroeconomic effects of government spending shocks in an economy characterized by positive trend growth. It shows that the lower is the trend growth rate the less inflationary are government spending shocks and vice versa. Moreover, on impact output is higher but exhibits...

Unlike previous empirical studies that focus on barriers to entry in international trade, we focus on barriers to exit as measured by passport costs for a crosssection of countries. We test four common theories on the determinants of such exit barriers and find that macroeconomic and brain-drain...

Many economists believe that, while openness to trade increases average GDP growth rates, it also raises output volatility by exposing countries to terms-oftrade shocks. This view does not take into account that, as suggested by a recent strand of the financial fragility literature, commercial...

Financial stability is an important policy objective, since crises are associated with large economic, social and political costs. Promoting stability requires preventing 'sudden stops' in capital flows, which are events in which foreign financing abruptly disappears. This paper contributes to...

This paper evaluates under which conditions different Taylor-type rules lead to determinacy and expectational stability (E-stability) of rational expectations equilibrium in a simple 'New Keynesian' small open economy model, developed by Gali and Monacelli (2005). In particular, we extend the...
