Ungewisse Wechselkurspolitiken und Zinsfestsetzung Wir untersuchen, wie ungewisse Wechselkurspolitiken die Zinsdifferenzen zwischen Ländern beeinflussen, die einem gelenkten Wechselkurssystem angehören. Es wird gezeigt, daß der Zinssatz in einer kleinen offenen Volkswirtschaft gemessen an dem...

We extend the analysis of Christoffersen and Diebold (1998) on long-run forecasting in cointegrated systems to multicointegrated systems. For the forecast evaluation we consider several loss functions, each of which has a particular interpretation in the context of stock-flow models where...

Delineation of the relevant market forms a pivotal part of most antitrust cases. The standard approach is sequential. First the product market is delineated, then the geographical market is defined. Demand and supply substitution in both the product dimension and the geographical dimension will...

A regime dependent VAR model is suggested that allows long memory (fractional integration) in each of the observed regime states as well as the possibility of fractional cointegration. The model is motivated by the dynamics of electricity prices where the transmission of power is subject to...

This paper introduces a representation of an integrated vectortime series in which the coefficient of multiple correlation computed fromthe long-run covariance matrix of the innovation sequences is a primitiveparameter of the model. Based on this representation, a notion of nearcointegration is...

The prototypical Lee-Carter mortality model is characterized by a single common time factor that loads differently across age groups. In this paper, we propose a parametric factor model for the term structure of mortality where multiple factors are designed to influence the age groups...

Do business cycle fluctuations leave a role and a welfare case for an active stabilization policy by means of fiscal policy instruments? We address this issue in a two-sector open economy model with price-taking firms and imperfect competition in the labour market. Fiscal policies are shown to...

Within the frame of the Nordic welfare model, pension system design has taken very different routes. While the overall aims in terms of distribution and replacement rates are similar, the division of labour between defined benefit and contribution as well as pay-as-you-go versus funded schemes...

A growing literature explores reasons for rising wealth inequality, but disregards the role of pension systems despite their well-understood infiuence on life-cycle saving. In theory and according to available evidence, both pay-as-you-go (PAYG) and fully-funded (FF) pension schemes crowd out...

Denmark is often highlighted as a "flexicurity" country with lax employment protection legislation, generous unemployment insurance, and active labor market policies. This model has coped with the Great Recession and the Covid-19 pandemic, avoiding large increases in long-term and structural...
