Note(s): The standard errors in parentheses are heteroskedasticity consistent. We employ *, ** and *** to denote statistical significance at the 10, 5 and 1% levels, respectively. p values are presented in brackets. The TMi variable has been instrumented by its second, third and fourth moments, following the methodology of Lewbel (1997). The dependent variable is environmental tax morality on a five-point scale
