New: Market Structure and Competition: Evidence from a Natural Experiment in Liquor Licensure
Date Posted:

2018
Washington state licensed private retailers to sell spirits for the first time in May 2012, but only if their premises exceeded 10,000ft. This restriction generates exogenous variation in the number of retailers across local liquor markets, which we leverage to estimate the causal effects of market structure on equilibrium outcomes. We find that spirits purchasing increases by 63% when moving from monopoly to duopoly markets, and that this increase is concentrated among the heaviest-drinking households. These results support the notion that local liquor availability can dramatically increase consumption. However, these effects dissipate quickly as the number of competitors increases, highlighting that the square-footage based licensure rule is a blunt policy tool. Surprisingly, price competition does not play an important role in the observed quantity increase. Instead, we find that firms compete in product assortment, tailoring product mix to the local competitive environment while ...
Update: Estimating the Effect of Potential Entry on Market Outcomes Using a Licensure Threshold
Date Posted:

We study the effects of potential entry on market outcomes in the context of Washington state's 2012 switch from a state-run monopoly to private liquor sales. Concern about alcohol-related crime prompted regulators to institute a 10,000 square foot licensure requirement to curtail entry. This store size threshold generates plausibly exogenous variation in the number of eligible entrants in local liquor markets across the state. We find that widening the pool of potential entrants has a small effect on pricing, but a significant effect on product offerings. In particular, markets with more potential entrants see a compositional shift in product offerings towards cheaper goods. Further, we find that the size requirement changes the composition of entrant size, rather than the aggregate number of entrants.
