A Computer program based on the genetic approach has been developed by the author as a supplementary tool for business cycle research. The program applied to a set of cross-section or time series data tries to discover the most probable relationships between economic variables and to determine their impact on cyclical developments in the economy. Unlike in standard econometric models, the point here is not merely to estimate parameters of certain specified equations, but also to identify the proper structure of the model. Preliminary tests of the program, on a set of variables entering the composite leading indicator for Poland deve!oped by Z. Matkowski, indicate a significant analytical potential of the program.
