Fixing random seed

• It is desirable that the default behavior of Dynare be fully deterministic: two runs of the same *.mod file on the same installation should provide the same results.
• The seed of both uniform and normal random generator is to be fixed in global_initialization.m
• Each Dynare command that uses a random generator must have an option letting the user use a different fixed seed or a variable seed based on time for example.

List of commands or functions that use a random generator

• stoch_simul (csolve simult_ + currently call to dynare_simul_ uses a fixed seed)
• estimation
  • mode optimization
  • Metropolis iterations
  • subsampling for posterior statistics
• osr optimization
• steady (csolve)
• ramsey_policy (csolve + simult_)
• Markov switching
