  We investigate unification of two systems of identical elements having
different dimensions which may be of interest for both physics and economics.
Characteristic parameters as well as explicit formulae for the temperature (in
economics - capital turnover) and dimension of the united system are obtained
as functions of parameters of the initial systems. Expressions also found for
the entropies of initial and united system. The process of unification is
accompanied by the transfer of particles (money) between the systems and
explicit expression is obtained for the transferred number of particles (size
of the capital). A relation between parameters of the initial systems also
found which defines the regime with zero particle transfer.
