I am wondering whether there is way to circumvent the single-frequency framework of Dynare. I have an optimisation problem in mind, in which some variables can be chosen in each period but others only every second period. Let’s take for example capital, K, to be a variable which can only be chosen every second period. That would imply that in all even periods K is state variable and in all odd periods K is a controll variable.
Do you have an idea how to handle that? Maybe with some auxiliary variables?
Thanks in advance and best regards
