    We assess the causes and implications of the greater nancial participation in commodity markets post-2003. Focusing on crude oil, we build a calibrated macro- nance model of oil prices and quantities that also determines consumer welfare. We show that shifts in the preferences and constraints…

    Theory-consistent models have to be kept small to be tractable. If they are to forecast well, they have to condition on data that are unmodelled, noisy, patchy and about the future. Agents can also use these data to form their own expectations. In this paper we illustrate a scheme for jointly…

    In this document we lay out the microeconomic foundations of a dynamic stochastic general equilibrium model, called Policy Analysis Tool Applied to Colombian Needs (PATACON), designed as a forecast tool and as a guide to advise monetary policy authorities in Colombia. In companion documents we…

    There is now an impetus to apply dynamic stochastic general equilibrium models to forecasting. But these models typically rely on purpose-built data, for example on tradable and nontradable sector outputs. How then do we know that the model will forecast well, in advance? We develop an early…
