Monopsony power and poverty: The unequal consequences of Walmart supercenter openings
Join this event to hear Zach Parolin discuss how Walmart Supercenter openings affect poverty and tax/transfer outcomes among individuals in affected counties.

Prior research suggests that Walmart Supercenters exert substantial power over the low-wage labor market, though the consequences of Supercenter openings on household incomes and public finances are less clear.
In this event, Zach will talk about his research, which uses restricted-access U.S. Panel Study of Income Dynamics data from 1970 to 2019. He will discuss the effects of Walmart’s monopsony power.
This event will be particularly useful for researchers.
Please note this is a hybrid event and can be joined either in-person or online.
