In order to have random effects there has to be variability within the unit of analysis. If the unit is the individual then you need to have more than one observation per individual. If the unit is city then you need to have more than one observation per city.

I have a data set on individual wage incomes along with education and

gives different returns to different people therefore the coefficient
for education is random coefficient: everyone has an unique slope.
but I only have one year of data on individual wage incomes.  So it is
still possible to use random coefficient model?

Hi all, does someone know if it is possible to estimate a random
coefficient model with cross-sectional data? if not, why not? thanks.

So the answer is, yes you can. The question is more about whether the
model makes sense. My example doesn't make any sense, and for your model
we need more information to comment on it.
