Clustered standard errors in parentheses. *p < 0.05, **p < 0.01, ***p < 0.001.

Each reported coefficient estimate in this table is obtained from a separate regression. The reported coefficient estimates correspond to the interaction term between the intervention supermarket banner (Loblaws) and the intervention period (after August 10, 2012). Weekly, day of week, and store fixed effects are included in each regression. Results are weighted by Universal Product Code (UPC). The data compare intervention relative to control (Zehrs) supermarkets from June 1, 2012, to February 28, 2013, with the postimplementation period after August 10, 2012. The unit of observation is store‐day. Results rounded to the nearest thousandth.
