Geneviève holds a Joint Honours B.Sc in Mathematics and Economics and a MA in Economics with a concentration in Data Science. Her research interests are in applied econometrics. She is contributing to the Methods of Payment Study and doing some analysis using the Transaction Duration Study Data.
Using an exclusive data set of payment times for retail transactions made in Canada, I show that cash is the most time-efficient method of payment (MOP) when compared with payments by debit and credit cards. I model payment efficiency using Cox proportional hazard models, accounting for consumer choice of MOP.
