What Do Endogenous Growth Models Contribute?

Endogenous growth theory is one of the mainstream economics approaches to modelling economic growth. This paper provides a non-technical overview of some key strands of the endogenous growth theory (EGT) literature, providing references to key articles and texts. The intended audience is policy analysts who want to understand the intuition behind EGT models. The paper should be accessible to someone without much economics training.Endogenous Growth, Innovation

Competition and Financial Stability in European Cooperative Banks

Cooperative banks are a driving force for socially committed business at the local level, accounting for around one fifth of the European Union (EU) bank deposits and loans. Despite their importance, little is known about the relationship between bank stability and competition for these small credit institutions. Does competition affect the stability of cooperative banks? Does the financial stability of banks increase/decrease when competition is higher? We assess the dynamic relationship between competition and bank soundness (both in the short and long run) among European cooperative banks between 1998 and 2009. We obtain three main results. First, we provide evidence in line with the competition-stability view proposed by Boyd and De Nicolò (2005). Bank market power negatively “Granger-causes” banks’soundness, meaning that there is a positive relationship between competition and stability. Second, we find that this fundamental relationship does not change during the 2007–2009 financial crisis. Third, we show that increased homogeneity in the cooperative banking sector positively affects bank soundness. Our findings have important policy implications for designing and implementing regulations that enhance the overall stability of the financial system and in particular of the cooperative banking sector

Emergent matter from 3d generalised group field theories

We identify classical solutions of a generalised group field theory model in 3 dimensions, and study the corresponding perturbations, deriving their effective dynamics. We discuss their interpretation as emergent matter fields. This allows us, on the one hand to test the proposed mechanism for emergence of matter as a phase of group field theory, and on the other hand to expose some limitations of the generalised group field theory formalism.Comment: 14 pages, 1 figure, RevTex4, v
