Keynes on the ‘Trade Cycle’

Keynes, throughout the “General Theory,” was concerned with explaining how his marginalist equation of “equilibrium” — marginal efficiency of capital = rate of (money) interest — could correspond to mass unemployment. The industrial cycle itself was of secondary concern for him. Nevertheless, in Chapter 22, entitled “Notes on the Trade Cycle,” Keynes does deal with the industrial cycle, or as he called it in the English manner, the “trade cycle.”

Keynes Attempts To Generalize Marginalist Theory

In previous chapters, we saw that Keynes denied that the unpaid labor of the working class produced surplus value. So, how does surplus value — profit, interest, and rent — arise, according to Keynes, if the working class does not produce it?

Ricardo and Marx vs. Keynes

Ricardo, unlike Adam Smith, attempted to use the law of labor value consistently. He sensed that this law applied not only to simple commodity production but also to capitalism proper. Ricardo was only partially successful in this, but he was on the right track. He realized that price is a relationship between the commodities whose price is being measured and the money commodity — gold — in which the commodity’s price is reckoned.

Liberation Day

On April 2, President Trump announced his “Liberation Day” tariffs. As this blog concentrates on economic questions, this was the biggest event of the last month. But before I get to the tariff, I’ll look at other developments.

Kilmar Abrego Garcia lived and worked legally in Maryland since 2019. The Trump administration accused him of belonging to a gang, arrested and put him on a plane heading for a notoriously brutal El Salvadoran prison. He had not been convicted of any crime. They then claimed they’d committed an administrative mistake.

On April 10, the Supreme Court unanimously ordered the return of Kilmar Abrego Garcia. As of this writing (April 28), he remains imprisoned, and Trump has refused to follow the court’s order. [I wonder whether the high court regrets last year’s decision that even after leaving office, a president cannot be criminally prosecuted for any action taken while in office in pursuit of their duties? I don’t know the answer, but it seems the court is like a man sawing off the branch he is sitting on. -SW]
