Say we have some yearly data, and we want to simulate a fictitious outcome at the month level, say this outcome is tax revenue generated by a given sector, where GDP = log GDP per capita, emp = percentage of the population that's employed, dens = population density and pop = the natural log of the population. Say revenue is meant to be measured in millions, we've just scaled it down from there.
Here we have half my dataset, which should be quite enough for these purposes. Currently, I generate the outcome (revenue) as
But, suppose I wanted to simulate a more complicated process at the monthly level. How might I do this? Would I expand each city-year by 12 for twelve months, and come up with a similar data-generating process at the monthly level?
