Cybersecurity breaches pose a substantial privacy concern in the digital era. We investigate how customers respond to privacy leakage in multiple unexpected data breaches. Difference-in-differences estimates show that digital payments declined by 4.6% ~ 7.5% relative to cash payments immediately...

We develop and implement a Bayesian Semi-parametric model of demand under inter-product competition that enables us to assess the respective contributions of branding hierarchy and inter-product similarity to explaining and predicting demand. To incorporate branding hierarchy effects, we use...
