Frisch, M. Kalecki and (slightly later) in works of J. Tinbergen and R.M. Goodwin. Some models considered in these works and some new models of this kind are sometimes presented on the lectures on mathematical economics. The purpose of this article is to present (on example of M. Kalecki‘ s business cycle model) some capabilities of computer algebra system Mathematica in solving of DDEs and graphic presentation of solutions}, title={Mathematica® na usługach ekonomii}, type={artykuł}, keywords={computer algebra systems, delay differentia equations, Kalecki‘s business cycle model, Mathematica®}, }
