WHY WAGES AND INCOMES HAVE BEEN
STAGNATING
According to Nobel
laureate and influential public intellectual Joseph Stiglitz, “In the US, the bottom
90% has endured income stagnation for a third of a century. Median income for
full-time male workers is actually lower in real (inflation-adjusted) terms
than it was 42 years ago. At the bottom, real wages are comparable to their
level 60 years ago.”
These statistics drive much of the
current political debate in the United States, Canada and most other Western
democracies. The trouble is that they measure the wrong thing. Wages and
incomes determine the amount of market goods and services consumers can buy. But
through time public demand has shifted increasingly to the provision of non-market
goods that determine well being and are supplied by governments: the stability
and predictability of income, the quality of the environment and characteristics
of national culture.
Politicians have responded to
these demands with a vengeance. There now are public insurance programs that
make incomes more stable and predictable: government-run insurance against the
results of personal ill health, accidents, unemployment and retirement. For the
entire economy there are regulations for the prevention of financial
instability, global warming and harm to the safety of consumers and workers.
The public has also demanded
policies that affect its sense of well being by making it feel good: policies
to clean the environment; make the distributions of incomes and wealth more
equal; create racial and gender equality; accept large numbers of immigrants
and refugees and create a multi-cultural society.
There are several aspects of these
government policies, which bear directly on the problem of low wages and
incomes discussed by Stiglitz. First, the benefits from social insurance programs
involve the redistribution of incomes. The value of the programs to society is
assumed to be equal to the governments’ cost of operating them, which means
that these programs can never increase the productivity of labour and capital
and lead to higher average incomes and wages.
Second, policies aimed at the
delivery of other non-market goods result in ephemeral, non-measurable benefits
at an uncertain time in the future that cannot be recorded in wage-increasing current
income, as is the case with policies preventing of global warming or financial
crises.
Third, while these non-market
benefits are not recorded in national income, their creation results in the use
of labour and capital that is withdrawn from the production of market goods.
The value of resources used by regulatory agencies and by private firms complying
with regulations has been estimated to be worth $1.8 trillion in the United
States in 2015.
In addition, some regulations reduce
economic growth by imposing costs and delays on entrepreneurship and innovation.
Some regulations actually lower growth, as will happen if the efficient use of
fossil fuel is replaced by the less efficient use of renewable sources of
energy to create electricity. (The US Supreme Court has in fact stopped this
replacement on the grounds that the costs are too large.)
In effect, these economic consequences
of regulations show again that there is no such thing as a free lunch. The more
the public wants greater security in all aspects of their lives and more feel-good
policies, the smaller will be incomes and wages that can be used to buy market
goods.
These public preferences can also
explain the vexing puzzle why since 2008 interest rates near zero have not generated
economic growth. The reason is that reduced incomes and wages of the public
have lowered the demand for private goods and the need for growth-generating
investments by so much that even the very low interest rates are insufficient
to induce private sector investment and cause cash-rich companies to buy back
shares or their competitors.
The shift of the public demand
from market to non-market goods has profound implications for economic policies.
Expansionary monetary and fiscal policies to stimulate the production of market
goods must fail because the stock of labour and capital are finite and already
utilized fully in the production of market and public goods. In addition, expansionary
monetary policy will create inflation and expansionary fiscal deficits will
eventually become unsustainable. Both pathologies can be cured only by
recessions and fiscal austerity.
The preceding analysis does not
imply that the growth in the production of non-market goods has failed to
increase the well being of the public. However, it does suggest that the public
needs to be aware that it is impossible to have both, more market and
non-market goods and that asking politicians to ignore this fact will lead to
inflation and austerity in the future and possibly much more instability and
lower levels of income and wages.
