Regulators should curb rip-off bills that hurt consumers and drag down the economy

Economists warn that weak competition, opaque pricing and perverse contracts in energy, telecoms and insurance markets are symptoms of asymmetric information, where firms know far more than consumers. This misallocation of resources amounts to a market failure, stifling efficiency and raising firms’ producer surplus at the cost of households. Without regulatory intervention, consumers remain locked into unfair contracts — a case for stronger watchdogs to restore transparency, enhance contestability and boost productivity across essential services.
