Input-Output DSGE Model for the Czech Republic
Input-Output DSGE Model for the Czech Republic

Summary/Abstract: This study questions the importance of accounting for sectoral heterogeneity in a DSGE model for the Czech Republic. The benchmark DSGE model originally developed by the Czech Ministry of Finance benefits from features such as wage and price stickiness, habit formation in the utility function and capital adjustment costs. The Input-Output DSGE model extended hereby proves to provide more precise estimates for the evolution of aggregate variables and to supply a more detailed structure of the economy. The set of variables the dynamics of which significantly improve consists of inflation rate and nominal interest rate. The disaggregated model also fits data well in terms of sectoral production functions. Finally, the absence of industrial heterogeneity in the model is shown to lead to an underestimation of the impact of the technology shock on the Czech gross domestic product.
