There's nothing in Keynesian economics that would allow you to solve stagflation. But there's nothing in neoclassical economics that would allow you to solve stagflation, either.
Interpretation
The quote highlights the limitations of both Keynesian and neoclassical economics in addressing stagflation.
In this quote, Paul Samuelson emphasizes the challenges posed by stagflation, a situation characterized by stagnant economic growth and high inflation. He asserts that neither Keynesian economics, which focuses on total spending in the economy and its effects on output and inflation, nor neoclassical economics, which emphasizes free markets and the importance of supply and demand, provide effective solutions to this complex issue, indicating a significant gap in economic theories when faced with such phenomena.
In practice
In a lecture about economic theory, one could use this quote to illustrate the limitations of different economic frameworks.
To a person of analytical ability, perceptive enough to realise that mathematical equipment was a powerful sword in economics, the world of economics was his or her oyster in 1935. The terrain was strewn with beautiful theorems begging to be picked up and arranged in unified order.
I can't think of a president who has been overburdened by a knowledge of economics.
My belief is that nothing that can be expressed by mathematics cannot be expressed by careful use of literary words.
Politicians like to tell people what they want to hear - and what they want to hear is what won't happen.
My family was well off but not rich. I spent the four years I was an undergraduate working on the beach. And it wasn't because I was lazy; it was because my freshman class would go to a hundred different employers and wouldn't get a nibble. That was a disequilibrium system. I realized that the ordinary old-fashioned Euclidean geometry didn't apply.
Economics has never been a science - and it is even less now than a few years ago.
The culture of self-gratification and deregulation that began during the Clinton years and continued under President George W. Bush led to the bursting of one stock market bubble at the turn of the century and a full-scale financial crash less than a decade later.
We contend that for a nation to try to tax itself into prosperity is like a man standing in a bucket and trying to lift himself up by the handle.
There is only one difference between a bad economist and a good one: the bad economist confines himself to the visible effect; the good economist takes into account both the effect that can be seen and those effects that must be foreseen.
As our economy faces up to potential labour shortages due to our ageing population and as it moves to a new level of sophistication to compete with the rest of the world, we're going to need every Australian on board pulling their weight, rejoining the workforce, gaining new skills. Writing off individuals and communities suffering from poverty just creates a dead weight for our economy to drag along.
Inequality has risen to the point that it seems to me worthwhile for the U.S. to seriously consider taking the risk of making our economy more rewarding for more of the people.
There would be plenty of justification to raise revenues in order to subsidize businesses that employ low-wage workers. But there can be no justification for pandering to the economy's entire bottom half merely to attract its votes.
