Incorporating commodity stockholding into a general equilibrium model of the global economy
نویسندگان
چکیده
Applied General Equilibrium (AGE) models are increasingly used for short-run commodity market analysis, although they are generally not designed for such purposes. This study remedies a key shortcoming of such work by incorporating a commodity stockholding model into a short-run global AGE model. An approach to calibrating and validating the model is demonstrated for the staple grains sector. Its historical weather-induced supply shocks form a natural vehicle for reconciling model outcomes with observed behavior. The stockholding model, in conjunction with a Gaussian Quadrature approach to characterizing supply-side uncertainty, will prove useful to researchers seeking to conduct short-run analysis of commodity market policy in an AGE context.

متن کاملEffect of Sentiments on Macroeconomic Variables in Iran: A Dynamic Stochastic General Equilibrium Approach
This study aims to evaluate the effect of sentiments on Iran's economy through a New Keynesian Dynamic Stochastic General Equilibrium model in a closed economy. In this study, the coefficients of the proposed model are calibrated and estimated using the quarterly data of Iran's economy from 2004 to 2015. It shows that in the presence of sentiment, how stochastic impulses affect the main macroec...
