Controller bieten dem Management interne Beratung und Unterstützung aus dem Blickwinkel finanzieller Handlungsmotive an (vgl. Kesten 2001, S.30 ff.). Dies trifft auch bei der Planung, Abwicklung und Kontrolle von Projekten zu. Der Beratungsfokus liegt dabei insbesondere auf Fragen zur...

Public-private partnerships have emerged as an alternative to traditional public procurement in financing and providing infrastructure services. This paper considers public-private partnerships as another form of public sector intervention in the economy. It analyses the microeconomic pros and...

This paper critically assesses the implications of contract design and risk transfer on the provision of public services under public-private partnerships (PPPs). Two results stand out. First, the alleged strength of PPPs in delivering infrastructure projects on budget more often than...

An welchen Kriterien sollte sich die Entscheidung über die bestmögliche Aufgabenverteilung zwischen staatlichen Stellen und privaten Akteuren bezüglich Finanzierung, Erstellung und Betrieb öffentlicher Infrastruktureinrichtungen orientieren? Während die unmittelbare Erstellung der...

By disaggregating price indices, it becomes apparent that the real exchange rate consists of the real exchange rate for a single good and a weighted sum of relative prices between goods. When applying a battery of panel unit root tests to this sum and its components, it is found that both the...

In this paper we present a critical overview of differnt methods of constructing an equilibrium exchange rate. The recent literature on purchasing power parity (PPP) indicates that on its own PPP is not a good vehicle for defining an equilibrium exchange rate. Rather, we argue that the latter...

We test for mean reversion in real exchange rates using a recently developed unit root test for non-normal processes based on quantile autoregression inference in semi-parametric and non-parametric settings. The quantile regression approach allows us to directly capture the impact of different...

In this paper we show the consequences of applying a panel unit root test when testing for a purchasing power parity relationship. The distribution of the tests investigated, including the IPS test of Im et al (1997), are influenced by a common stochastic trend which is usually not accounted...

We examine the asymptotic behavior of unit root tests against nonlinear alternatives of the exponential smooth transition type if the data is erroneously nonlinearly transformed. We show analytically and by a Monte Carlo study that the probability of rejecting the correct null of a random walk...

This paper considers two problem classes that are important to researchers as well as practitioners, namely packing and project scheduling problems. First, the two problem categories are described. This includes a classification of packing problems as well as of project scheduling concepts....
