A
regression of popularity (Government considered excellent/good, source
Datafolha, very similar to Ibope or Census, but longer data) in four
determinants: (i) lag of popularity, (ii) GDP growth, (iii) inflation, (iv)
real exchange rate.
Is unemployment
irrelevant? Yes, in contrast with some specifications I saw around, which forgot
to put lagged variables and had nonstationary residuals, I found unemployment
to be irrelevant. I’m happy with this, as the unemployment series is total
crap.
Are the
regressors endogenous? Shit yeah.
In the
first picture a forecast. Assuming growth at 2%, inflation at 6% and BRL at
2.40, popularity trends up to 45. Shit yeah.
In the
second picture, which shows the residual of the regression, a curiosity. The
effect of the “passe livre” street movement was huge, but vanished.
