I have performed a difference-in-differences analysis with the following regression:

Priceit = β0 + β1regioni + β2postt + αDİD(regioni * postt) + uit

region is a dummy variable taking 1 in the high tourist density (treatment region), 0 in low tourist density (control region)
post is an another dummy variable taking 1 in the post-pandemic period, 0 in the pre-pandemic period.

Could you please help me how to interpret the coefficients?

Thanks in advance.
