I’m new in using Dynare,

- so I want to know how I write the below expression.

(ex) pi=beta*(1-thetah)*E_t(pi(t+1)) + thetha*pi(t-1) + lambdah*mc + e

where E_t is the current expectation parameter.

In this case, in Dynare code,

pi = beta*(1-thetah)*pi(+1) + thetah*pi(-1) + lambdah*mc + e

is the correct expression?

Is the expectation(E) term expressed as merely parameter(+1), like this?

- when I was exercising, Dynare warning was expressed as below

Warning: File ‘newzealand2_optimal_mh_scale_parameter.mat’ not found

Warning: File ‘newzealand2/Output’ not found

Warning: File ‘newzealand2/metropolis’ not found

What’s the meaning of the above warning? What can I do for solving these problem?

Please help me and thank you for your attetion.
