* SF: has rent control, prices go up.

* Cambridge: removes rent control, prices go up.

How do you show the causal relationship? Seems like there's constrained housing supply everywhere.

Why look at the price rather than the population/housing capacity growth? If you have housing for 500000 residents and 600000 looking for housing or living in the city then prices will go up simply because demand outstrips supply as you said. The demand probably grows every single year.

Rent goes up because people can afford it, so this is actually not a problem that needs to be solved. What needs to be solved is the fact that 100000 people cannot find a place in the city at all. No matter how low or high the price of rent is, you will always have a shortage of 100000 units if you're not increasing the supply.

snakemake does this trivially:

    rule analyze_country:
        input: 'whatever.{country}.txt'
        output: 'analysis.{country}.txt'
        shell:
            'run-analysis-on-country {input} {output} --country=country'

    rule analyze_target_countries:
        input: ['analysis.usa.txt', 'analysis.canada.txt', 'analysis.mexico.txt']

Small change, you have to use wilcards.country inside the shell call:

    rule analyze_country:
        input: 'whatever.{country}.txt'
        output: 'analysis.{country}.txt'
        shell:
            'run-analysis-on-country {input} {output} --country={wildcards.country}'
