Incompatibility in markets with network effects can either benefit or harm consumers. Incompatibility reduces consumers’ ability to “mix and match” components offered by different sellers, but can also be associated with changes in product attributes that might benefit consumers. In this paper, we estimate the effects of incompatibility in a classic hardware/software market: ATM cards and machi...

BACKGROUND Cervical auscultation (CA) is an affordable, non-invasive technique used to observe sounds occurring during swallowing. CA involves swallowing characterization via stethoscopes or microphones, while accelerometers can detect other vibratory signals. While the effects of fluid viscosity on swallowing accelerometry signals is well understood, there are still open questions about these ...

We investigate the role of industry specialization in horizontal cross-border mergers and acquisitions. We find that acquirers from more specialized industries in a country are more likely to buy foreign targets in countries that are less specialized in these same industries. The role of industry specialization in foreign acquisitions is more prevalent when contracting inefficiencies and export...
