Sensitive analysis for change in parameters value

Stochastic simulations
2

What you describe is a straightforward problem with two components:

  1. Looping over parameters in Dynare. There are many posts dealing with that. Your code above is not recommended as you should loop over the Matlab-function stoch_simul. See

  2. Plotting the data. You can use any Matlab command you like for that.
