Deepening Uncertainty, A New Role for Government Policy The COVID-19 pandemic, the war in Ukraine, and global supply chain disruptions have shaken economies worldwide over the past few years, creating a new landscape. Amidst rapid inflation and vulnerable supply systems, countries around the world are unusually strengthening government intervention in markets to stabilize their economies. Indeed, the concept of 'price controls' was once considered a violation of free markets. However, in today's age of uncertainty, its necessity is becoming prominent, signaling a paradigm shift in economic policy. Andy Beckett, a columnist for The Guardian, recently argued in an op-ed that price controls are no longer a taboo but can be an essential choice. He pointed out that the pandemic weakened trust in existing economic systems and highlighted the need for governments to actively stabilize the economy, emphasizing an expanded role for government in curbing inflation, stabilizing the supply of essential goods, and addressing social inequality. Historically, price controls were implemented as an anti-inflation measure during the Nixon administration in the U.S. in the 1970s, but they were deemed a failure due to side effects such as supply shortages and the formation of black markets. However, Beckett analyzes that today's complex crisis situations create a different context than in the past. South Korea was no exception to these changes. In recent years, the South Korean government has keenly felt the need for market intervention amidst various economic crises and implemented diverse policies. From 2022 to 2024, the government reduced fuel taxes by up to 37% to ease the burden of fuel costs on citizens, and from the second half of 2022 to the first half of 2023, it suppressed electricity bill increases, alleviating energy cost burdens for households and businesses. During the surge in heating costs in early 2024, the government strengthened the social safety net by providing approximately 2 trillion won in energy vouchers to vulnerable groups. While these measures contributed to short-term price stability, they simultaneously raised concerns about increased fiscal burden and market distortion. Similar movements are observed internationally. In October 2022, the UK government introduced the Energy Price Guarantee, setting a cap on household energy bills. This policy allowed the average household to save approximately £900 in energy costs annually, but it resulted in a government fiscal burden of about £60 billion. France implemented even stricter price controls by limiting electricity bill increases to 4% in 2022, while Spain and Portugal, granted exceptions from EU regulations, introduced caps on natural gas prices. This represents widespread government intervention rarely seen in the post-war free market economic system, suggesting a shift in the global economic paradigm. However, the side effects of market intervention should not be overlooked. A key mechanism of a free market economy lies in ensuring the autonomy for businesses and individuals to exercise their unique dynamism. Excessive regulation can stifle the creativity and competitiveness of the private sector, which could negatively impact long-term economic growth. Economists point out that while price controls can alleviate consumer burdens in the short term, they can lead to problems such as reduced supply, lower quality, and the formation of black markets in the long run. Indeed, Venezuela implemented extensive price controls from the mid-2000s, but this led to shortages of essential goods and hyperinflation, becoming one of the causes of its economic collapse. The Pros and Cons of Market Intervention: Cases and Arguments According to a 2024 research report by the International Monetary Fund (IMF), approximately 68% of 53 countries that implemented price control policies either withdrew or significantly eased them within five years, and the average economic growth rate of these countries was 1.2 percentage points lower than that of countries with similar income levels during the policy implementation period. This provides empirical evidence that market intervention must be carefully designed and operated on a temporary basis. Some experts warn that if governments strengthen direct interventions like price controls, businesses might shift to government-policy-dependent business models, which could diminish long-term economic vitality. So, under what circumstances is government market intervention desirable? Economically, the most important justification for government intervention in the market is to balance efficiency and equity. In specific crisis situations, markets often cannot mitigate crises autonomously, which is when government intervention becomes necessary. Nobel laureate in economics, Joseph Stiglitz, explains through the concept of market failure that government intervention is justified when issues such as information asymmetry, externalities, a
