Multihoming in the market for payment media: Evidence from young Finnish consumers

We aim at explaining why some consumers use only one medium when paying for their point-of-sale transactions, while others multihome and use many. Using data on young Finnish consumers, we find that one key determinant of multihoming behavior in the market for payment media is consumer awareness. Our instrumental variable estimates indicate that the better informed use 1.2-1.3 times more payment media than the less informed. Because many payment method innovations are typically first used simultaneously with the established methods, our results suggest that increasing consumer awareness could significantly speed up the adoption of new means of payment, such electronic money and mobile payments.
