World urbanization processes have reached, first time in history, a metropolitan scale in the 2nd. half of the 20 C. We have to build the discipline required to address this new challenge.
The growth of metropolises is due to the higher efficiency of these compared with the rural or urban units, even medium-sized cities when they are not part of the metropolis context. But this efficiency is only reached when the administration is capable of managing it and avoid the congestion gridlock when growth is unmanaged.
Financing the necessary structural investments confront two main difficulties:
- The public/private sectors' share for efficient economic complementary.
- The formal/informal sector's taxing share, direct and indirect taxes, in a low or medium income economy to finance the necessary indivisible public goods. |
