Wêrom hierkontrôle wenningmerken altyd ferslechteret yn teory en soms ferbetteret yn praktyk

Textbook economics says rent control shrinks housing supply. But when landlords cannot extract monopoly profits, markets sometimes work better for renters.
FryskYn 1994 fêstige San Francisco de hierferheagingen op ynflaasje plus 1 persint. Ekonomen foarseinen ramp. It oanbod soe yninoar falle. Leechstân soe eksplodearje. Gebouwen soene ferlitten reitsje. Neat fan dat alles barde. Leechstân troch ferhierders sakke. Hierderferrin sakke. De wenningfoarried stabilisearre.
Ekonomyske modellen ferûnderstelle dat ferhierders rasjoneel nei opbringsten op lange termyn stribje. Dat kloppet net. In protte ferhierders eksploitearje lokale ynformaasje, ferheegje hierren as fraach piket, ferlitte de merk dan as opbringsten sakje. Hierkontrôle twinget in kar: bliuwe foar 4 persint opbringst of fuortgean. Guon geane fuort. Oaren bliuwe, om't 4 persint garandearre better is as de 10 persint dy't sy nea krigen.
Ekomen wite wenningtekort oan hierkontrôle. Mar it tekort kaam earst. San Francisco hie tekort yn de jierren tachtich, foardat kontrôles kamen. New York ek. Berlyn ek. Kontrôles fertrage soms ferslechtering, feroarsaakje dy net. Ûndersyk sjocht dêr net nei.
Wêrom net? Om't fêstguodlobby's tsjin hierkontrôle fjochtsje. Jild streamet nei stúdzjes dy't bewize dat kontrôles mislearje, net nei stúdzjes dy't freegje oft se helpe wêr't se foar bedoeld binne. Peer-reviewed literatuer nimt sûnder fraach oan dat merken regels oertreffe. Dat dogge sy net, as ôfwêzich kapitaal dominearet.
Hierkontrôle wurket nea perfekt. Mar de toets is ienfâldich: wurket it better as it alternatyf? In stêd dêr't hier de helte fan dyn lean opslurpt en nimmen dy't dêr wurket der wenje kin. Soms wint saai priisregeling fan elegante ekonomyske teory.
In 1994, San Francisco capped rent increases at inflation plus 1 percent. Economists predicted disaster. Supply would crash. Vacancy would soar. Buildings would sit empty. None of that happened. Landlord vacancy rates fell. Tenant turnover dropped. The housing stock stabilized.
Economic models assume landlords pursue long-term returns rationally. That is wrong. Many landlords exploit local information, spike rents when demand peaks, then abandon the market when returns fall. Rent control forces a choice: stay at 4 percent returns or leave. Some leave. Others stay, because a guaranteed 4 percent beats the 10 percent they never got in the first place.
Economists blame rent control for shortage. But shortage came first. San Francisco had shortage in the 1980s before controls arrived. New York did too. Berlin did too. Controls sometimes slow worsening, not cause it. The research does not look at that.
Why not? Because real estate lobbies fight rent control hard. Money flows to studies proving controls fail, not studies asking whether they help the people they target. Peer-reviewed literature accepts, without question, that markets outperform rules. They do not, when absentee capital dominates.
Rent control never works perfectly. But the test is simple: does it work better than the alternative? A city where rent swallows half your wage and nobody who works there can live there. Sometimes boring price regulation beats elegant economic theory.
