Cluster sampling has recently been used to estimate the mortality in various conflicts around the world. The Burnham et al. (2006) study on Iraq employs a new variant of this cluster sampling methodology. The stated methodology of Burnham et al. (2006) is to (1) select a random main street, (2)...

We present a model of monetary policy where the policymaker faces uncertainty about wich he is learning in a Bayesian fashion. A fixed money supply levels. A fixed money supply rule is not optimal in this context since the learning leads to constant adjustments in money supply levels. We present...

It is still unknown whether there is some deep structure to modern wars and terrorist campaigns that could allow reliable prediction of future patterns of violent events. Recent war research focuses on size distributions of violent events, with size defined by the number of people killed in each...

Analysis of our new, 16-year dataset on the Colombian civil war finds under Uribe: guerrilla and paramilitary attacks dropping sharply to long-run averages since 1988, lower for April- December, 2003; government- guerrilla clashes at all-time highs, exceeding guerrilla attacks; civilian killings...

We compare the treatment of Colombia in large cross-country conflict datasets with the information of the detailed micro dataset of Restrepo, Spagat and Vargas (2003). We find a general tendency of the big datasets to underestimate the magnitude of the Colombian conflict and to mischaracterize...

We present a detailed, high-frequency dataset on the civil conflict in Colombia during the period 1988-2002. We briefly introduce the Colombian case and the methodological issues that hinder data collection in civil wars, before presenting the pattern over time of conflict actions and intensity...
