In this paper, it is argued that the observed high positive correlation between national savings and investment which is found in the data can in part be explained by shocks to monetary policy. This hypothesis, which is established by reviewing some empirical findings, is tested in a two-country...

Much analysis in macroeconomics empirically addresses economy-wide incentives behind consumer/investment choices by using insights from the way a single representative household would behave. Heterogeneity at the micro level can jeopardize attempts to back up the representative consumer...

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...
