I am trying to measure the effects of restrictions on immigration to a specific country on both real estate rental indices and real estate property price indices during the next 3 to 5 years. As a software, I am using Eviews and I would like to calculate two alternative scenarios. A VECM (vector error correction model) should be used for simulating the effects of changes in population numbers on different macroeconomic variables (GDP, consumer price index, interest rates). Rental prices are straightforward to estimate in an error correction setting. How would you derive a pricing formula for the real estate price index? Would you consider using FM-OLS (Fully Modified OLS) or DOLS (Dynamic OLS) using the mentioned macroeconomic variables as cointegrated variables? The equation structure will be linked by a model object within Eviews for running forecasting simulations.
