The paper bases itself on recent theoretical writings in growth economics that emphasize the effects of both own R&D efforts and of interregional technology spillovers on regions´ productivity. We propose robust estimation techniques to evaluate the R&D spillovers across West German functional...

We study an overlapping generations model of human capital accumulation with threshold effects using regional data for West Germany. Our basic goal is to shed light on the growth of West German regions. The paper finds that the relative income distribution appears to be stratifying into a...

With recovery from the global financial crisis in 2009 and 2010, inflation emerged as a major concern for many central banks in emerging Asia. We use data observed at mixed frequencies to estimate the movement of Chinese headline inflation within the framework of a state-space model, and then...

On 21 July 2005 China adopted an undisclosed basket exchange rate regime. We formally assess and envisage the gradual evolution of the renminbi over time. We utilise nonlinear dependencies in the renminbi exchange rate and describe the smooth transition of the renminbi/US dollar (RMB/USD)...

Labour costs in various European countries have reached a record high in recent years. The topic of non-wage labour costs is therefore increasingly being discussed among and between the political parties because non-wage labour costs are likely to have major negative effects on employment. We...

This paper examines the impact of Knightian uncertainty upon optimal climate policy through the prism of a continuous-time real option modelling framework. We analytically determine optimal intertemporal climate policies under ambiguity. Additionally, numerical simulations are provided to...

This paper presents a theoretical framework analysing the signalling channel of exchange rate interventions as an informational trigger. We develop an implicit target zone framework with learning in order to model the signalling channel. The theoretical premise of the model is that interventions...
