The article is a comment in a discussion on conditions concerning design and usage of macroeconomic models. Building of macromodels is determined by three elements: theory of economics, within the scope of which they are built, accessible modelling techniques, and sets of reliable numerical data. The use of macromodels results from the guidelines of economic policy, and their structure is determined by concrete current and future challenges connected with creating of strategic visions of economic development. In the article, the authors also highlight the dynamic of globalization processes which, together with the effects of the global crisis of the period 2007-2009, provide new perspectives for creators of macroeconomic models. In addition, the article provides numerous examples of model constructions and recommendations concerning utilization of model techniques in the process of making macroeconomic decisions.
