摘要：The WM-1 model is the first macromodel of the Polish economy based on monthly data.Most time series are generated by non-stationary processes.Therefore the estimation has been made in such a way that it allows for the cointegration of the variables (ECM, TECM and CVAR models were used).This prevented spurious regressions and ensured appropriate statistical inference.A specification of all the behavioral equations follows economic theory.The model also exploits data from Input-Output tables.In the case of many important equations, the asymmetry of the reactions has been taken into account.
