Stagnation, according to Hansen, stems<br />
from a slowdown in technological<br />
progress…<br />
…but sluggish job creation in digital<br />
industries does not necessarily imply a<br />
slower or faster pace of innovation<br />

Over recent decades, the US economy has witnessed a downward trend in<br />
indicators of technological dynamism: the rate of business startups and the pace of<br />
job relocation have recently fallen, while the share of US employment accounted for<br />
by young firms has declined sharply throughout the 2000s. 109 Even the high-tech<br />
sector started to decline in the post-2000 period, experiencing a shift in economic<br />
activity away from young to more mature firms.<br />
An appealing, but mostly neglected, explanation for this is offered by the life-cycle<br />
pattern of the computer revolution. As investment in computer and information<br />
processing equipment surged throughout the 1980s and 1990s, a wide range of<br />
entirely new computer-related jobs were created. Beyond the peak investment<br />
stage in 2000, however, the US economy experienced a decline in the demand for<br />
new work relative to the early stages of the computer revolution. 110 The question<br />
thus arises: where will the next generation of capital-absorbing innovations come<br />
from?<br />
In Hansen’s framework, stagnation stems from a slowdown in technological<br />
progress, resulting in fewer investment opportunities. Indeed, a number of<br />
economists, including Robert Gordon and Tyler Cowen, have suggested that the<br />
most useful innovations have already been made. 111 Yet the technological<br />
opportunities offered by the digital revolution may well be greater than anything we<br />
have seen in the past.<br />
Crucially, the sluggish job creation in digital industries does not necessarily imply a<br />
slower or faster pace of innovation. Instead, it stems from the fact that digital<br />
innovation is much less capital-absorbing, meaning that there is little demand for<br />
labour to build the new capital. While WhatsApp started with $250,000 of seed<br />
funding, they still only employed 55 workers at the time the company was acquired<br />
for $19 billion.<br />
That the digital economy may cause secular stagnation is a real risk. 112 The simple<br />
reason is that businesses of the digital revolution require less capital investment<br />
and thus fewer workers to build the new capital, relative to the investment<br />
opportunities brought by technological revolutions of the past. As economies are<br />
becoming increasingly digitised, investment opportunities will continue tapering off.<br />
Accompanied with a rising share of profits, the savings glut is likely to persist.<br />
Macro Policy Implications<br />
The risk of secular stagnation has significant implications for policy. The stance of<br />
monetary policy at any moment depends crucially on the output gap, or the<br />
difference between potential GDP, which assumes full utilisation of available inputs<br />
(land, labour and capital), and actual GDP, the amount of expenditure actually<br />
occurring in the economy. When potential GDP is running above actual, this means<br />
that slack and underutilisation is abundant, leading to downward pressure on wages<br />
and prices and thereby to action by the central bank to ease monetary policy to<br />
meet its inflation target. Conversely, actual GDP running above potential implies an<br />
overheating economy and a tightening stance of monetary policy.<br />
