Hello,

I post below a results table for a diff in diff model. For simplicities sake, please look only at model M2. Here we see my policy variable is insignificant, implying the policy did not have a significant effect on the dependent variable "weight." Also, We see the covariate wealth is insignificant. However, the interaction of wealth and policy variables (variable "wealthxpolicy") is significant. How do I interpret this? Does this suggest that while the policy did not have an average effect on "weight," it does have an effect for wealthier (given the positive coefficient) individuals?

Many thanks for reading.
