This article attempts to present the question of ideas of Polish heterodox economist Michał Kalecki on the planned economies and general problems with capitalist and post-capitalist systems. To analyze the problem I start with Kalecki’'s theory of capitalist crisis, question of effective demand and full employment, and then describe the quasi-model of democratic planned economy. Next, I focus on relations of workers’' self-management with central planning and motivation problems under state-run economy. I also put on agenda the so-called shortage problem, analyzed by the Kalecki’'s supporter, Andrea Szego, in opposition to neo-classical approach of Hungarian economist Janos Kornai.
