Wage and Price rigidities in an economy - Evaluate the statement “Wage and price
rigidities are necessary for Keynesian economics to explain involuntary unemployment”
with reference to Keynes’s general theory, New Keynesian economics and the orthodox
Keynesian school.
The statement that "wage and price rigidities are necessary for Keynesian economics to explain
involuntary unemployment" is a central tenet of Keynesian thought, and its evaluation requires a
careful examination of how different schools of Keynesian economics have approached this
issue.
Keynes's General Theory: The Starting Point
In his seminal work, The General Theory of Employment, Interest and Money, John Maynard
Keynes challenged the classical orthodoxy that believed in self-correcting markets and the idea
that flexible wages would automatically restore full employment. Classical economists argued
that if there was unemployment, a drop in wages would reduce labor costs, leading firms to hire
more workers until the market cleared.
Keynes, however, had a different view. He acknowledged that workers were concerned with
their nominal wages (the amount of money they were paid), not just their real wages (their
purchasing power). He noted that workers would resist nominal wage cuts, even if a proportional
drop in prices would leave their real wages unchanged. This resistance to downward nominal
wage adjustments—a form of wage rigidity—was crucial to his analysis.
However, Keynes's argument went beyond simple wage stickiness. He contended that even if
wages were perfectly flexible, a general wage cut would not necessarily cure unemployment. A
widespread reduction in wages would lead to a decrease in aggregate demand, as workers would
have less money to spend. This decline in demand would, in turn, reduce firms' incentive to
produce and hire, potentially leading to even more unemployment. Therefore, for Keynes, while
wage stickiness was an important factor contributing to persistent unemployment, it was not the
sole cause. His focus was on the more fundamental issue of inadequate aggregate demand.
