This 'unconditional convergence
', which is not found in agriculture or services, can provide a powerful engine of structural transformation and growth, but its significance depends on the pace of industrialization.
Second, there is unconditional convergence
in energy intensity over time, both in the recent period and over the last two centuries.
He defines unconditional convergence
as implying that the coefficient in a growth-initial level regression should be negative even if no other variable, such as education, is included.
This, however, again leads to a coupling of h and k, and thus destroys unconditional convergence
. The problem can be reduced by using the Newton method for the midpoint scheme, which empirically allows for larger time steps; see  and also , where an efficient Newton-multigrid nonlinear solver has been proposed.
In particular, they show that services have exhibited "unconditional convergence
" in productivity recently.
investigates unconditional convergence
. The key element of unconditional convergence
is to look at whether the levels of regional economy will converge to a constant vector for all the regions over a specific time period.
Overall, both the conditional and unconditional convergence
models prove that Romania has an important role in the CEE regional convergence.
However, we believe that unconditional convergence
may not be expected when heterogeneous factors' endowment across countries is obvious.
From this inequality we can see the unconditional convergence
in W([L.sub.p], [l.sub.[infinity]])([[??].sup.d]) norm, too, if c [member of] [s.sub.p,[infinity],0].
