  We propose a novel approach to generate chaotic business cycles in a
deterministic setting. Rather than producing chaos endogenously, we consider
aggregate economic models with limit cycles and equilibriums, subject them to
chaotic exogenous shocks and obtain chaotic cyclical motions. Thus, we
emphasize that chaotic cycles, which are inevitable in economics, are not only
interior properties of economic models, but also can be considered as a result
of interaction of several economical systems. This provides a comprehension of
chaos (unpredictability, lack of forecasting) and control of chaos as a global
economic phenomenon from the deterministic point of view.
  We suppose that the results of our paper are contribution to the mixed
exogenous-endogenous theories of business cycles in classification by P.A.
Samuelson [76]. Moreover, they demonstrate that the irregularity of the
extended chaos can be structured, and this distinguishes them from the
generalized synchronization. The advantage of the knowledge of the structure is
that by applying instruments, which already have been developed for
deterministic chaos one can control the chaos, emphasizing a parameter or a
type of motion. For the globalization of cyclic chaos phenomenon we utilize new
mechanisms such that entrainment by chaos, attraction of chaotic cycles by
equilibriums and bifurcation of chaotic cycles developed in our earlier papers.
