Firms and Cities Have Open Borders
Originally published on Overcoming Bias
Outline
- Cities don't usually limit who can move there
- If you can find someone to give you housing and a job, you can usually move to a city
 - Cities don't add much in the way of requirements over landlords and employers
 
 - Large firms also don't tend to limit who can work for them
- Each particular unit might care who joins it
 - Firm overall tends to defer to "local" decisions
 - Firms which have commitments to helping workers change teams impose more control
 
 - Given the obvious analogies to cities and firms, why do nation-states have such tight borders?
- Analogy is strongest when people who enter nations only do so with jobs and housing waiting for them
 - Also, the nation has to have relatively few obligations to the people entering
 
 - Do firms and cities have open borders because national boundaries do the filtering for them?
- Nations don't do very much filtering on the metrics that firms and cities tend to be interested in
 - Wide variation between people already inside a nation-state
 - Multinationals have employees in many nations, but still tend to defer to local decisions on who to hire
 
 - Firms and cities exist in environments that are more competitive than the environments that nation-states exist in
 - Entities that exist in competitive environments tend not to create entity-wide limits on who can enter them
 - If nations behave differently than firms, it's because either
- There are larger important effects that matter at the national level that don't matter at the city or firm level
 - Nations are failing to adopt policies that they would be forced to adopt if they faced more competition
 
 - Robin Hanson thinks the problem is that nations are failing to adopt more open immigration policies because of lack of competition
 - Is there a market failure that makes open borders lamentable?
 - If not, we should be disappointed that nations don't have the same open borders that firms and cities do
 
My thoughts
- Firms don't have open borders
- Firms commonly interview candidates before admitting them in
 - The purpose of this interview is to both assess a candidate's qualifications and also whether they would reinforce or dilute the culture of the firm
 - Managers at firms often have limited headcount (analogous to immigration quotas) which forces them to turn away even qualified applicants who would be a good fit
 
 - To the extent that cities and firms have open borders, it's because they're forced to by the federal government
- Employment law limits the ways in which firms may choose to select workers (i.e. can't select based upon race, gender, sexual orientation, religion, etc.)
 - Federal laws also limit the ability of cities to exclude people
- Laws against "redlining"
 - Prohibiting "sundown laws"
 - Laws prohibiting restrictions on who may or may not buy property in the city
 
 - Even still, cities use zoning law to do their best to exclude the wrong sorts of people
 - In other countries, such as China, cities have a much greater ability to exclude people -- "hukou"
 
 - Firms can relatively easily fire people in the US
- Revoking a visa is much more difficult by comparison
 - Revoking someone's citizenship is practically impossible
 - In states where it's much more difficult to fire people, firms are much more careful about hiring, to the point where unemployment and underemployment is significantly higher as a result
 
 - It seems to me that the entire premise of the post is mistaken
- Nation-state governments exclude less than firms
 - Firms and cities would exclude even more than they already do if they were allowed to by nation-state governments
