***, **, and * denote 99%, 95%, and 90% levels of confidence. Two sided t-tests were used. Standard errors are shown in the parenthesis. Unhealthy food was purchased under each intervention (lower tax and rebate) though regular tax rate was applied for unhealthy food under each treatments. Demographic characteristics (shown in Tables 1–3) were used as control variables (shown as “yes”). Their effects are presented in a different report (Banerjee et al., under preparation).
