Wêrom hierkontrôle teoretysk min wurket en yn de praktyk soms better
August 9, 2026 · Frisian News
Rent control looks terrible in textbooks but works better in practice when paired with public housing investment. Germany's failed Berlin policy and Vienna's successful approach show the difference.
FryskBerlijn beheinde hierferhegingen oant 3% it jier yn 2020. De bou fan nije appartementen sakke mei 20% it folgjende jier. Ferhierders lûken kapitaal fuort. It oanbodargumint like wetterdicht: legere prizen deadzje de prikkel om te bouwen, krimp it oanbod, meitsje skarsens. Mar de data fertelde in oar ferhaal. Hierprizen yn net-kontrôlearre wiken stegen hurder, en hierders mei lege ynkommens yn Berlijn bleauwen wenjen ynstee fan djoere ferhuzingen.
Elk ekonomyhânboek leart deselde les: priiskontrôle makket skarsens. De hânboeken hawwe gelyk. Set prizen ûnder de merkwearde en do deadzgest de prikkel om oanbod te jaan. Wêrom renovearest in gebou as do de hier net ferheegje meist? De logika stimt. Mar hânboeklogika giet út fan ienfâldige merken mei rasjonele akteurs dy't allinne winst neijeie.
Echte wenningmerken binne yngewikkelder. Ferhierders ferdwine net as hieren beheind binne. Lege gebouwen kostje ek jild. Wenen hâldt sûnt desennia strange hierkontrôle oan. De leechstân is likernôch 1%, ien fan de leechsten fan Europa. Ferhierders bouwe noch, ûnderhâlde noch, konkurearje noch om goede hierders. De kontrôle skeint harren ynkommens. Mar ferlitting skeint mear. De merk past him oan ynstee fan dea te gean.
Wa profitearret fan frije hierprizen? Net boulju of húsbehearders. Massyfe ynvestearringsfûnsen en makelaardsfûnsen dy't gebouwen keapje om se troch te ferkeapjen. Dizze bedriuwen lobbyen hurd tsjin kontrôle en ferspriede it ferhaal dat kontrôle de merk ferneaticht. Dat ferhaal folt akademyske tiidskriften en opinypagina's. It hat machtige freonen. De wiere data is yngewikkelder en berikket minder minsken.
It earlike antwurd: hierkontrôle mislearret as it prizen beheint sûnder nije wenningen te bouwen. It wurket better keppele oan agressyfe omsonearring en direkte oerheidswenningbou. Berlijn syn maatregel fan 2020 mislearre om't it wenjen as priisproblem seach, net as oanbodproblem. Wenen syn kontrôle bliuwt bestean om't Wenen echt appartementen bout. De teory kloppet. De beliedsflater wie hierkontrôle as inkeld middel te sjen.
Berlin capped rent increases at 3% per year in 2020. New apartment construction fell 20% the next year. Landlords pulled capital out. The supply argument seemed airtight: lower prices reduce incentive to build, shrink supply, create scarcity. But the data told a different story. Rents in uncontrolled neighboring areas shot up faster, and low-income tenants in Berlin's controlled units stayed put instead of cycling through expensive moves.
Every economics textbook teaches the same lesson: price controls create shortages. The textbooks are right. Cap prices below the market rate and you kill the incentive to supply. Why renovate a building if you cannot charge market rent? The logic is sound. But textbook logic assumes simple markets with rational actors who only chase profit.
Real housing markets are messier. Landlords do not vanish when rents are capped. Empty buildings cost money too. Vienna has enforced strict rent controls for decades. Its vacancy rate sits around 1%, among Europe's lowest. Landlords still build, still maintain, still compete for good tenants. The controls hurt their income. But abandonment hurts more. The market adapts rather than dies.
Who wins from uncontrolled rents? Not construction workers or property managers. Massive investment firms and real estate funds that buy buildings to flip them for profit. These firms lobby hard against controls and push the story that controls destroy housing. That story fills academic journals and op-ed pages. It has powerful friends. The actual data is messier and fewer people hear it.
The honest answer: rent controls fail when they cap prices without building new units. They work better when paired with aggressive zoning reform and direct public housing investment. Berlin's 2020 cap failed because it treated housing as a price problem, not a supply problem. Vienna's controls endure because Vienna actually builds apartments. The theory is correct. The policy mistake was treating rent control as a standalone fix.
