my question is multidimensional:
I employed a difference-in-differences (DiD) approach to assess the impact of a treatment (an agreement) on exports. The DiD coefficient, obtained as -0.573 and statistically significant, with log-transformed variables, is this value interpreted as a percentage change? Can it be stated that exports were 57.3% lower due to the treatment?
Furthermore, to estimate the counterfactual exports, can I multiply the treated group's exports after the agreement by -0.573 and just plot it with the AVERAGE exports of the control group?
Can the counterfactual analysis and the graph be performed using software like STATA or R?
Thank you in advance.
