This paper is concerned with modified Kaldor-Kalecki models of
business cycles with delays.We introduce the model with unidirectional and bidirectional couplings to investigate the relationship between the European Union, Chinese, American economy (global markets)  and the  Polish, German (local) economy.
We examine the impact of the delay on the action of the local and global markets with respect to the unidirectional coupling. In the paper we present the results of numerical analysis.
