Effects of the Sunday Shopping Restriction in Korea

Abstract

We examine the effectiveness of Korea's Sunday superstore shopping regulation, whose purpose is to protect small‐ and medium‐sized retailers as well as traditional markets. Applying a two‐way random‐effects regression model to the daily sales data of four megastores and four super supermarkets, we find the net sales decrease of superstores is on average 5.61% of daily sales after taking into account sales increases due to consumers' switching to weekdays. Only about 17%–19% of the reduced superstore sales are transferred to traditional markets. Based on these estimates, the compensating variation per year is predicted to be 2.4–2.5 trillion Korean won (around US $2.1–2.2 billion).
