Many important economic problems require measures of physical and R&D capital. Except for some recent studies, there have been relatively few contributions in the literature that provide econometric estimates for the depreciation rates of physical and R&D capital. One reason for the relative...

Steuerreformen im Bereich der Kapitaleinkommensbesteuerung führen zu einer Beeinflussung der internationalen Kapitalbewegungen, denen letztlich eine Verzerrung der internationalen Kapitalallokation infolge ineffizienter internationaler Investitions- und Sparentscheidungen, also ein globaler...

In this contribution a nonparametric estimator for the hazard function will be presented for time-discrete survival analysis. The estimator is derived from a likelihood function based upon time-discrete counting processes. With martingale techniques asymptotic properties of the estimator of the...

This paper analyses the consequences of tightening environmental policy for economic growth. To find out how the new balanced growth path is reached in the long run, we simulate numerically for the short and medium term the transition path of a change in environmental policy within an endogenous...

Reliable estimates of variances and covariances are crucial for portfolio management and risk controlling. This paper investigates alternative methods to estimate time varying variance-covariance matrices: ordinary estimates and exponentially weighted moving averages in comparison to Markov...

This paper investigates the relation between agglomeration of economic activity and the pattern of specialization of countries. We develop a model encompassing a Ricardian comparative advantage, increasing returns to scale, product differentiation, monopolistic competition, trade costs, and...

The mortality of German joint stock companies is investigated using life table techniques. An EDB-distribution or Hjorth-distribution and an exponential distribution are fitted to the hazard rates, whereby the population is divided into small and large firms. Survivor functions and life...

Die Diskussion um flexible versus fixe Wechselkurse und die Bemühungen um stabilere Wechselkurse, etwa im Rahmen des europäischen WährungsSystems, durch Präferenzzonen (Williamson 1985) oder einen Goldstandard ohne Gold (McKinnon 1988) geben der Literatur um die Mechanismen zum Ausgleich der...

Nichtparametrische Verfahren zur Dichte- und Regressionsschätzung setzen die Wahl eines Glättungsparameters voraus. Ein oft verwendetes Verfahren zu dessen Bestimmung ist die Kreuzvalidierung. Die Übertragung dieser Methode auf die Quantiisregression ist Gegenstand der vorliegenden Arbeit. Es...
