An empirical analysis of cellular demand in South Africa

Gasmi, Farid; Ivaldi, Marc; Recuero Virto, Laura - C.E.P.R. Discussion Papers - 2009

We analyze demand for prepaid cellular voice and short message service (SMS) in South Africa by means of a demand-and-supply structural model based on a multinomial specification fitted to a cross-sectional data set on Vodacom customers collected in 2005. We find that consumers are very...

Economic Linkages Across Space

Overman, Henry G; Rice, Patricia; Venables, Anthony J - C.E.P.R. Discussion Papers - 2008

We develop a diagrammatic framework that can be used to study the economic linkages between regions or cities. Hitherto, such linkages have not been the primary focus of either the theoretical or empirical literatures. We use the framework to analyse the impact of shocks that occur in one region...

Combes, Pierre-Philippe; Duranton, Gilles; Overman, Henry G - C.E.P.R. Discussion Papers - 2005

We consider the literatures on urban systems and New Economic Geography to examine questions concerning agglomeration and how areas respond to shocks to the economic environment. We first propose a diagrammatic framework to compare the two approaches. We then use this framework to study a number...

Carrillo, Juan D - C.E.P.R. Discussion Papers - 2006

The Brain as a Hierarchical Organization

Brocas, Isabelle; Carrillo, Juan D - C.E.P.R. Discussion Papers - 2005

We model the brain as a multi-agent organization. Based on recent neuroscience evidence, we assume that different systems of the brain have different time-horizons and different access to information. Introducing asymmetric information as a restriction on optimal choices generates endogenous...

Reason, Emotion and Information Processing in the Brain

Brocas, Isabelle; Carrillo, Juan D - C.E.P.R. Discussion Papers - 2007

Building on evidence from neurobiology and neuroscience, we model the physiological limitations faced by individuals in the process of decision-making that starts with sensory perception and ends in action selection. The brain sets a neuronal threshold, observes whether the neuronal cell firing...

Some studies find … that if workers grow older there is an increasing gap between productivity and wages, i.e. wages increase with age while … productivity does not or does not increase at the same pace. However, other studies find no evidence of such an age related pay …
