Two of the most discussed issues triggered by the so called Feldstein-Horioka puzzle in international macroeconomics are: What does the saving-investment (SI) relation really measure and how should the SI relation be measured? The first contribution of this study is to develop a new variant of...

Knowledge diffusion models typically involve two main features: an underlying social network topology on one side, and a particular design of interaction rules driving knowledge transmission on the other side. Acknowledging the need for realistic topologies and adoption behaviors backed by...

We compare the individual-based \'threshold model\' of innovation diffusion in the version which has been studied by Young (1998), with an aggregate model we derived from it. This model allows us to formalise and test hypotheses on the influence of individual characteristics upon global...

Long-term outlooks are key tools for policy design in the energy sector. These outlooks should also include scenarios considering active policies that address the challenge of climate change. Consequently such a CO2 emission reduction scenario was analysed as a case study within the ACROPOLIS...

The low capital mobility among OECD countries, signalled by a high saving-investment (SI) relation and known as the Feldstein-Horioka puzzle, has triggered a lively discussion in the empirical literature. In this paper, we compare between, pooled, time and country dependent specifications of the...
