I have a question related to the timing convection in Dynare. I have been working with a search model in which employment evolves as follows:

n_{t} = f(n_{t-1}) + g(u_{t-1},v_{t-1})

where n is employment, u and v denote unemployment and vacancies, respectively. In my understanding, employment is a predetermined variable in my case. Is this correct? If so, do I need do specify employment to be a predetermined variable?

As far as I know (Forward looking & predetermined variables), the following formulation is not identical:

n_{t+1} = f(n_{t}) + g(u_{t},v_{t})

True?

Best,
