short and long run restrictions

[asdavies6032]

I Need some help,
I want to construct a VAR model using short and long run restictions with 8 variables (real GDP, house price index, housing starts, GDP deflator, commodity price index, federal funds rate, mortgage interest rate, and nonborrowed reserve).My policy variable is the federal funds rate. I am confused as to how to set up the short run and long run restrictions. Any help will be appreciated

Is this an economic question or a technical one? If it's the latter, what do you have as your restrictions?
