Tyler Cowen on the Great Stagnation

Innovation Plateaus

Tyler Cowen argues that the U.S. economy faces a period of stagnation due to technological plateaus and the exhaustion of "low hanging fruits" of innovation. He explains that while past innovations like the automobile and industrial machinery brought rapid growth, finding the next breakthrough is increasingly challenging 1. Russ Roberts adds that sectors like finance and healthcare have seen growth, but not necessarily in ways that enhance productivity 2.

In 1963, people were not very good at playing heads I win, tails you lose. By 2006, they become masters at it. That's a kind of innovation but it's more value destroying than value creating, that's for sure.

This highlights a shift towards innovations that may not contribute to overall economic prosperity.

   

Income Stagnation

The stagnation of median incomes is another critical aspect of Cowen's thesis. He notes that changes in household structures, such as increased divorce rates and more single-parent families, have skewed income data, making it appear as though there is less growth than there actually is 3. Russ Roberts points out that while median income is a better measure than mean income for assessing typical American affluence, it still has its flaws, particularly in how it accounts for inflation and purchasing power 4.

There are some biases in how we measure inflation, but if we look at people who have studied, when are those biases most likely to be large, very large? Those biases will be largest in periods when you have fundamentally new goods entering the marketplace and spreading.

These measurement challenges complicate the understanding of true economic growth.

   

Policy Impact

Cowen discusses how government policies have impacted economic growth, suggesting that many policies have distorted market incentives and contributed to stagnation. He advocates for policy improvements, such as deregulation and education reform, to stimulate growth 5. Russ Roberts adds that measuring economic transformation is complex, as traditional metrics often fail to capture the full scope of changes, such as technological advancements 6.

Innovation is a trial and error process. It's not smooth. And we have this illusion that it's 3% a year, that that's the growth rate of the American economy, and that's a bad bird's eye view.

--- Tyler Cowen

This underscores the need for a nuanced understanding of growth and policy impacts.
