The topic of the paper is relevant in the field of optimal growth theory and
therefore might be seen as an intellectual underpinning for research and practice in the
field of transition economies and sustainable long-time development as well. It refers
to the papers Panek (2015a, 2018) devoted to asymptotic properties of optimal growth
properties in the non-stationary Gale type economy with single and multi-lane turnpikes
in which it was assumed that changing production technology converges in time
with certain limits of technology. As far as the postulate of a non-stationary economy
(here: technology change) is consistent with real processes, the hypothesis of the existence
of some limiting technology may raise controversies and be difficult to verify.
In the paper, referring to the above mentioned publications and Panek (2014),
a Gale-type economy with changing technology, multi-lane turnpike and time-increasing
production efficiency, with no assumption concerning the existence of a limit
technology will be examined.
