I simplified the agtrend.mod code written by Sastien Villemot and Johannes Pfeifer and add three shock including the preference shock, interest rate shock and demand shock similar as financial friction model. But I got this result,

STEADY: The Jacobian contains Inf or NaN. The problem arises from:

STEADY: Derivative of Equation 2 with respect to Variable c (initial value of c: 0.551597)

STEADY: Derivative of Equation 2 with respect to Variable l (initial value of l: 0.448813)

STEADY: Derivative of Equation 2 with respect to Variable v (initial value of v: 0)

STEADY: The problem most often occurs, because a variable with

STEADY: exponent smaller than 1 has been initialized to 0. Taking the derivative

STEADY: and evaluating it at the steady state then results in a division by 0.

Could anyone tell me why?

Thanks
