We test whether firms use incompatibility strategically, using data from ATM markets. High ATM fees degrade the value of competitors' deposit accounts, and can in principle serve as a mechanism for siphoning depositors away from competitors or for creating deposit account differentiation. Our...

Incompatibility in market with network effects reduces consumers' ability to "mix and match" components offered by different sellers, but can also spur changes in product attributes that might benefit consumers. In this paper, we estimate the effects of incompatibility on consumers in a classic...

Incompatibility in markets with network effects can either benefit orharm consumers. Incompatibility reduces consumers' ability to "mixand match" components offered by different sellers, but can also beassociated with changes in product attributes that might benefitconsumers. In this paper, we...

We test whether a nonbinding price ceiling may serve as a focal point for tacit collusion, using data from the credit card market during the 1980's. Our empirical model can distinguish instances when firms match a binding ceiling from instances when firms tacitly collude at a nonbinding ceiling....

If consumers value 'mix and match' combinations of network complements, incompatibility between different sellers' components should affect prices. In ATM markets, a 1996 governance change exogenously generated such incompatibility, by allowing banks to impose surcharges when other banks'...

We test whether a non-binding price ceiling may serve as a focal point for tacit collusion. Our sample contains data from the credit card market during the 1980s; in the sample, most credit card issuers face a state-level interest rate ceiling, and well over half match their ceiling. Our...

Incompatibility in markets with network effects can either benefit or harm consumers. Incompatibility reduces consumers' ability to quot;mix and matchquot; components offered by different sellers, but can also be associated with changes in product attributes that might benefit consumers. In this...
