It’s no shock egg costs are hovering. In October 2024, UMASS – Amherst economist Isabella Weber argued that worth controls are wanted to maintain costs below management and, additional, that the controls wouldn’t have the damaging results we normally predict, similar to shortages, deadweight loss, and so on. I responded to her claims right here. One of many factors I raised was:
Moreover, because the worth being saved artificially low disincentivizes the provision curve from turning into elastic and/or rising, the prices of worth ceilings persist longer than they’d in any other case.
4 months later, we see this in motion. The excessive costs of eggs are inflicting individuals to think about turning to yard hen coops and even renting chickens. That is an instance of the Second Legislation of Demand: “Elasticities of demand with respect to cost are larger the longer the time after a worth change” (Common Economics by Armen Alchian and William Allen, p 116). In different phrases, the longer costs stay comparatively excessive, the extra individuals will get hold of or develop substitutes, making the demand curve extra elastic. The identical holds true for provide: the longer costs stay comparatively excessive, the extra artistic individuals will likely be to deliver provide to the market. When eggs have been $0.99 a dozen, it made little sense to have a yard hen coop, which has begin up prices of hundreds of {dollars}. However, with egg costs pushing the double-digits (a dozen giant eggs are promoting for $9 at my native retailer), now the relative worth of yard coops has fallen and individuals are turning to that various. The demand for eggs is turning into extra elastic. Identical with provide, as we see individuals with coops promoting or giving eggs to their neighbors.
With worth controls in place, this course of can be a lot more durable. The market is shifting towards an answer. Worth controls would have slowed this course of. Fairly than ending shortages and controlling inflation, Weber’s proposal would have simply turned the seen prices invisible.
Replace: The worth of eggs has fallen since I initially wrote this piece. The worth of a dozen eggs at my native retailer is now (as of three April) $5.79. Nonetheless, I can’t change the unique submit as a result of the drop helps the purpose I’m making right here.
