Please help me! I have this basic New Keynesian model but when executing, it gives the following error:
i) if all parameters occurring in these equations are defined
ii) that no division by an endogenous variable initialized to 0 occurs

As Dynare says, there is a problem with equation 4. You do not provide an initial value for pi, which is thus taken a 0. Equation 4 divides by pi which results in the error. Provide a starting value for pi.
