Dear Statusers,
I have a methodological question.
I have a county level data on the survival rate of firms after 6, 12, 18,
..., 48 months (see example of the dependent variable below), for a period
of 9 years.
I would like to analyze the effect of regional factors (deprivation, real
wages, average schooling, population density, etc) on the variation of these
aggregated survival rates over time.
My problem is that, as it stands, my dependent variable is tri-dimensional
(region, year, and time of operation).
I've done a search in the economic literature on firm survival and regional
economics, but I could not find any reference that would resemble the type
of data or the problem that I would like to explore. I would like to know if
anyone in the list has any suggestion of references that I might have missed
in economics, or if people on any other fields know of any references of
people looking at any data that might resemble this one (I don't know, but
maybe epidemiology might have regional level that might look at similar
issues).
Any suggestions will be much appreciated.
All the very best,
JP
