Economic Theory Explores Hypothetical Path to Stagflation Through Population Reduction

A recent tweet by author Derek Thompson has sparked discussion by positing a theoretical, unconventional method for engineering stagflation: "forcibly shrink the population while also raising prices, so that you'd get durable goods inflation, slowed GDP growth, and labor shortages all at the same time." This hypothetical scenario challenges conventional economic understanding of stagflation, a rare and challenging economic condition.

Stagflation is defined by the simultaneous occurrence of three phenomena: stagnant economic growth, high unemployment, and persistent inflation. Historically, this condition defies traditional economic models, which typically suggest an inverse relationship between inflation and unemployment. The most prominent historical example occurred in the 1970s, largely triggered by oil price shocks that increased production costs and reduced economic output.

While the notion of forcibly shrinking a population to induce economic conditions is not a recognized economic policy or theory, population dynamics do significantly impact economic indicators. Studies show that population decline can lead to slower GDP growth, primarily due to a shrinking labor force and reduced consumer demand. For instance, countries experiencing population decline often face an increasing dependency ratio, where a smaller working-age population supports a larger retired demographic, straining social security systems and potentially leading to labor shortages in specific sectors.

However, the direct link between population decline and inflation is complex and not straightforward. Some economic analyses suggest that population aging can exert deflationary pressures, as seen in Japan, due to decreased consumption and investment demand. Conversely, severe labor shortages resulting from a rapid population contraction could, in theory, drive up wages and production costs, contributing to inflationary pressures.

Thompson's tweet presents a thought experiment, combining elements that are individually known to influence economic health but are rarely, if ever, considered as deliberately engineered levers for stagflation. The economic consensus typically attributes stagflation to adverse supply shocks, such as sudden increases in commodity prices, or to misguided government policies that simultaneously restrict growth and expand the money supply. The idea of population manipulation as a deliberate economic tool remains firmly in the realm of speculative theory.
