Indeed, economic output is currently
far below the growth trajectory
that had been anticipated before
the 2009 economic crisis. Worse,
recent reports confirm that potential
output growth has declined in recent
years. This concerns not only high income
but also developing economies,
which could see a slowdown
in their adoption of productivity enhancing
technologies as their
investment and economic growth
slows. Whether this is primarily a
cyclical issue—and thus a legacy of
the economic setback in 2009—or a
more structural problem endangering
future growth is being vigorously
debated by economists.
