Hello Dr. Jumadi. Thank you for your question.
I tested for the normality of the unstandardized residual of the regression,
multicollinearity test, and heteroscedasticity test.
This study conducted monte Carlo simulation, by increasing the tax rate until Rp50
per kg CO2e. When the data still give the same conclusion, we recommended that
the model is good enough.
