The issues include the nature and functionality of the GMREM. In the first part of the text a one-equation model was constructed in which the effects of companies business activities are dependent on marketing activities, including marketing research. The second part presents a model of interdependent multiple equations. Ultimately a model in which the model parameters change over time is also considered}, title={Modeling marketing research efficiency - some theoretical notes}, type={artykuł}, keywords={marketing research, efficiency, GMREM model, efektywność, badania marketingowe}, }
