It uses Bayesian procedures to estimate a Dynamic Stochastic General Equilibrium (DSGE) model for a small open economy. The paper shows that natural gas and coal shocks are relevant sources of macroeconomic disruption in addition to oil price shocks. The three fossil fuel prices have an impact on the economic activity and explain the evolution of the energy mix. However, we find that oil price shocks have a significantly larger impact on economic volatility. Finally, we assess the impact of hydrocarbon price shocks on carbon emissions given that different price shocks result in a different fossil fuel mix and, thus, in different CO2 emissions.engAtribución-NoComercial-CompartirIgual 3.0 Españahttps://creativecommons.org/licenses/by-nc-sa/3.0/es/journal articlehttp://dx.doi.org/10.5547/01956574.38.6.jmaropen accessQ43Q40Q35Q31Energy pricesFossil fuelsDSGE modelsBayesian estimationSmall open economyCO2 emissions.PetrologíaMedio ambienteEconomía2391 Química Ambiental53 Ciencias Económicas
