The lack of euro area labour market flexibility is a commonly mentioned issue. In particular, the relatively weak response of wages to high unemployment can pose adjustment problems. We address the issue using extensive simulations of an estimated macro-econometric model for the euro area (the...

Using social network analysis, our first aim is to illuminate the relationships between the Islamists and the rebels involved in the Malian conflict. We use a selection of newspaper articles to demonstrate that the connection between Islamists and rebels depends on brokers who passed from the...

The present paper examines the importance of integrating geographic contextual effects into the analysis of social networks. By considering spatial structures as both produced by and productive of social relations, geographic space seems to be more than the extent on which places, actors or...

The recent literature on Purchasing Power Parity (PPP) has emphasized the role of two phenomena that may lead to the rejection of the PPP hypothesis: structural breaks and nonlinear adjustment induced by transaction costs. These two hypotheses are analyzed separately in the literature. We...

This paper investigates the relationship between per-capita human capital investment and the birth rate. Since the consequences of higher fertility (birth rate) on per-capita human capital accumulation (the so-called dilution effect) are not the same (in sign and magnitude) across different...

This paper investigates the relationship between per capita human capital investment and the fertility rate. In the first part of the article we analyze a theoretical model with endogenous birth rate in which we do not make any assumption on how fertility directly affects per capita human...

Given the decline in growth momentum in the manufacturing sector in many OECD countries, the role of knowledge-based capital has emerged as a key driver for sustained growth. While empirical studies on estimating knowledge spillovers have usually been undertaken at the country level, the...

Spillovers have usually been undertaken at the country level, the spillover effects can be more definitive only if the analysis is conducted at the industry-level. This paper therefore attempts to identify spillovers by disentangling technological innovations into intra- and inter-national...

This paper examines the direct effects of corporate tax on firm productivity along with the interaction effects of tax policy and R&D activity on productivity at firm level for over 13,062 firms during 2004-2011. Our main findings are first, that there is evidence for productivity convergence...
