### Gravity Model of international Trade

Posted:

**Tue May 28, 2019 10:27 am**Hey there!

For my thesis I have to estimate a Gravity Model of international Trade. I use over 30 countries during the time of 1990-2017. I have variables which vary over time (GDP and Exports) and constant variables (distance) as well as constant and changing dummies. I transferred my Data in 3d panel form to EViews, but now I am lost how to estimate the model.

I tried: equation eq.ln @log(exports_ij) c @log(GDP_ij) @log(distance) @dummy

but it is not working.

Further my GDP data is in current USD and my Exports in thousand current USD, how can I adjust those values?

Thank you in advance!
