I’ve been trying to estimate a simple extension of Gertler’s (1999) model with individuals going through three stages of life, rather than two. However, I have an issue with finding the steady state and I could not figure out what the problem is. I would appreciate any help.

Thank you! I tried simplifying the model, and estimating it without the production side but I still get the error: The Jacobian of the dynamic model contains Inf. Not sure if the issue could be with the calibration of one of the transition probabilities (p_y, p_m, n and s).
