<p>Can one forecast $\Delta Unemployment$ and $\Delta Inflation$ using a VAR model based on Okun's law?</p>

I'm currently working on that, but my main goal is structural analysis. I want to go further in predicting the path dependence of unemployment and I've been reading about Arma process mixed with neural networks that shows a good grade of accuracy. I hope this help in some way

Is there a reason you think you couldn't?  I popped "okun var" into Google scholar and there were all sorts of published results.

Well you can essentially forecast anything using a VAR/VECM framework.

If you're wondering if such estimates will be accurate the answer really depends on the region, as the Okun Coefficent differs depending on where you are. (much like the [law of gravity on earth](https://en.wikipedia.org/wiki/Gravity_of_Earth#Variation_in_gravity_and_apparent_gravity)).

a working paper released by the IMF titled [*Do Forecasters Beleive in Okun's Law?*](http://www.sciencedirect.com/science/article/pii/S0169207014000466) its conclusions were rather in favor for the use of Okun's law in forcasting.

Its generally more accurate for short run forecasts then it is for long run. However the same counter-cyclical relationship is maintained between Real GDP growth rate and Unemployment Rate.
