Knowledge drives the growth of nations and regions in a competitive space-economy. Hence, we would expect a strong correlation between investments in R&D, knowledge and learning processes, on the one hand, and productivity increases, on the other. However, the empirical evidence shows consistent...

The paper presents a multiregional endogenous growth model designed for calibration with real world data and for numerical policy evaluation. It integrates four strands of research: (1) the Ramsey model of consumer behaviour, (2) Tobin's q-theory of investment, (3) Romer's theory of endogenous...

I document novel stylized facts on learning and its relationship with population density, using Japanese survey data that provide distinctively rich first-hand information about the frequency, purpose, subject, and method of off-the-job learning. First, people learn more frequently in denser...

In this paper, we introduce a distinction between interregional and intraregional transportation costs, in a footloose capital model. This allows assessing more precisely the effects of different types of transport policies, on the spatial distribution of activities. From a normative point of...

Shift-share analysis is a decomposition technique widely used in regional studies to quantify an industry-mix effect and a competitive effect on the growth of regional employment (or any other relevant variable) relative to the national average. This technique has always been subject to...

We exploit the public good attributes of information and communication technologies (ICTs) and theoretically analyze an aggregate economy of two smart cities in which ICTs are provided in either a decentralized or a centralized manner. We first determine the efficient ICT levels that maximize...

We develop a dynamic spatial model in which heterogeneous workers are imperfectly mobile and forward-looking and yet all structural fundamentals can be inverted without assuming that the economy is in a stationary spatial equilibrium. Exploiting this novel feature of the model, we show that the...

Infolge der Regionalisierung von Wirtschafts- und Strukturpolitik entstehen entweder vollkommen neue Institutionen (horizontale Regionalisierung) oder Institutionen mit neuen Kompetenzen (vertikale Regionalisierung). Der Erfolg einer Regionalisierungspolitik läßt sich am Grad der...
