摘要：California legislation outlawed the use and sale of battery cages for egg-laying hens in 2015.While a number of ex ante studies projected the effects of the housing prohibitions, the ultimateex post effects are unknown. Using a price series reported by the USDA, we study the movementof daily egg prices in California and the United States before and after the law’s implementation.Depending on the methods used, we find that Californians now pay between $0.48 and $1.08more for a dozen eggs. The estimates suggest an annual reduction in California consumer surplusof between $400 million and $850 million.
