How effective are price controls? Let's take Hungary as an example!

Portfolio
Rising inflation is prompting governments to use price controls more to shield consumers from price increases. Hungary's controls on food items, including pork, since 2022 are an example. The aim was to reduce the effect of inflation on consumers. But how successful has it been and what unforeseen outcomes has it produced? Economists at the Centre for Economic and Regional Studies (KRTK) of the Hungarian Research Network (HUN-REN) answered such questions and more in a recent study.

Amid recent global inflationary pressures, governments have increasingly turned to price controls as a mechanism to protect consumers from rapid price increases. Hungary offers a particularly timely and illustrative case study, as it enacted significant price controls on various essential food items—including pork—beginning in February 2022. This policy was implemented explicitly to mitigate inflation’s burden on consumers, but how effective has it truly been, and what unforeseen outcomes has it produced?

In a recent study published in Agricultural and Food Economics, Tibor Bareith, Imre Fertő, Szilárd Podruzsik analysed the dynamics of price transmission within the Hungarian pork market from 2017 to 2023.

Their research specifically focused on understanding how farm-level pork prices (producer prices) influence the prices consumers pay in supermarkets.

Utilizing advanced econometric methods that accommodate both linear and nonlinear relationships, we sought to clarify the precise impacts of government-imposed price controls on market behaviour.

Their investigation uncovered

some critical and notable asymmetries in price transmission.

"We observed that increases in pork prices at the farm level were swiftly passed along to consumers by retailers. However, reductions in farm prices were not reflected as quickly or fully on supermarket shelves," they said.

This asymmetry resulted in consumers rarely experiencing the full benefits of price reductions at the farm level, despite regulatory efforts intended explicitly to protect them.

The researchers added that the speed and magnitude of these pricing adjustments illustrate a significant limitation of price controls, demonstrating that regulatory interventions alone are insufficient to guarantee equitable and responsive market outcomes.

As for the reasons, their findings indicate that

underlying structural factors, such as market concentration among processors and retailers, play a crucial role.

These market dynamics, characterized by limited competition and considerable market power of retailers, meant that

price decreases from producers did not effectively trickle down to benefit consumers.

Such market concentration allows supermarkets greater discretion in pricing strategies, enabling them to maintain higher consumer prices despite cost reductions at earlier stages in the supply chain.

The researchers stressed the significance of the practical implications of these findings.

They suggest that while price controls can offer short-term relief for consumers facing inflationary shocks, they may simultaneously create distortions in market behavior, reducing overall market efficiency.

They warned that policymakers considering similar interventions elsewhere must carefully weigh these potential unintended consequences.

This research provides timely and practical insights as inflation remains a pressing concern globally, they said.

"By closely examining Hungary’s recent experience with price controls, our study contributes valuable evidence to ongoing debates about the effectiveness of such policies. It also

underscores the necessity of coupling regulatory price interventions with broader measures aimed at enhancing market competitiveness and transparency.

Ultimately, their analysis suggests that sustainable consumer protection policies must go beyond simple price controls.

"Policymakers should prioritize fostering competitive market environments and transparency to ensure that consumer protection measures do not inadvertently hinder the market’s natural price-adjusting mechanisms. As global economic conditions continue to fluctuate, such nuanced, evidence-based policymaking will be crucial to safeguarding consumer interests while preserving market stability and fairness," the researchers concluded.
