Except for Libya, where the test is validated under risk aversion, all the other countries
appear to support the model under risk neutrality. But, even for Libya, the constant risk
aversion coefficient is 0.75 meaning that is not different from 1. Details related to the
options of calculations with the implied results are included in the appendix.
Given these results, it can be inferred that the theoretical model used in this research does
reproduce the data observed about the annual rates of emigration of medical doctors in
the region as they are given by the database used. This is in favor of using the theoretical
model selected to discuss the cases of each country and also the situation and trends in
the overall MENA region.

''()(,!Discussion of the Findings
Based on the results attained and given the level of emigration rate observed over the
period 1991-2004, all countries included in this analysis appear to be benefiting from
brain gains in the area of medical doctors. This means that domestic medical education is
operating such that economies can still support the emigration of medical doctors at the
current number of physicians in each country. Different results might be attained if the
current staffing rates are further increased above the current observed trends. Under the
current domestic educational system and with the current conditions of staffing, the
countries under study appear to be enjoying brain gains. But, there are major variations
expressed by the countries.
