Is there hope for an increase in potential growth?

An increase in potential growth would be welcome. It would ensure public debt sustainability without the need for a restrictive fiscal policy; it would enable faster wage growth or a faster reduction in working time. We can begin with: Potential growth = Total factor productivity growth + ɑ. Labour supply growth + (1 - ɑ). Productive capital growth where ɑ is a coefficient that represents the share of labour costs in total production. Looking at the various factors that explain potential growth in the cases of the United States, the euro zone, the United Kingdom and Japan, we see that it is highly unlikely that potential growth will pick up in the 2020s.
