Hi there,

I am quite new to eviews and I have been trying to estimate a model for my thesis. This model is a PHillips Curve model and I want to put restrictions on previous π_t sum to one.


For more clarification I am posting ym model here.#

π_t=1/4 ( π_(t-1)+π_(t-2)+π_(t-3)+π_(t-4) )+α(u-u*)t+ε_t

where π_t is annualized quarterly inflation rate
1/4 ( π_(t-1)+π_(t-2)+π_(t-3)+π_(t-4) is expected inflation ( expected inflation being an average og past four quarters )


I want my restriction to be that the coefficient of expected inflation to be sum to 1.


Can someone please help me how I command eviews to do this for me! Thank you

but how does that work?

Can I assumer the first set of pi-s to be a simple moving average model based on past four quarters? and then do the regression?

Yes and how can we obtain the coefficient and s.e. of the coefficient thats missing?

Do a Wald test on 1-c(2)-c(3)-c(4)=0
