Immigrant inflow lowers – A recent, in-depth analysis challenges conventional narratives surrounding immigration by revealing its significant role in stabilizing the cost of living. Contrary to fears of economic strain, a study indicates that an increase in the immigrant population correlates with lower prices for essential daily services. This dynamic effectively boosts the real purchasing power of domestic residents. Furthermore, the research finds the impact on the real wages of native workers to be minimal. These pivotal insights come from a report by the Korea Institute for Industrial Economics and Trade (KIET), titled ‘The Impact of Immigrant Inflow on Regional Prices,’ published on the 28th.
The study’s empirical foundation examines 39 major metropolitan areas—including Seoul, Busan, Daegu, and Incheon—over a thirteen-year period from 2010 to 2023. Its findings offer a nuanced understanding of how immigration shapes local economies, particularly through the lens of price adjustments in non-tradable service sectors.
A Catalyst for Price Stabilization in Daily Life
The core discovery of the KIET report is a direct link between immigration and reduced price inflation in sectors critical to everyday life. The analysis quantified that a 10 percentage point increase in a region’s immigrant inflow ratio led to a notable 0.598% to 0.645% decrease in the prices of non-tradable goods. This category encompasses services that cannot be imported or exported, such as dining at restaurants, haircuts and beauty treatments, and local healthcare services.
This deflationary effect is not uniform across all services but is particularly strong in specific areas. The study breaks down the impact on key components of the Consumer Price Index (CPI):
Public and Personal Services: A 10 percentage point rise in the immigrant ratio resulted in a 0.725% decrease in the CPI for public services and a 0.321% drop for personal services (excluding dining out). This phenomenon is largely attributed to an expanded supply of labor willing to fill roles in these often labor-intensive, lower-wage sectors, which alleviates upward pressure on operational costs and, consequently, consumer prices.
Education and Housing: Perhaps the most striking effects were observed in education services and housing costs. The same increase in immigrant ratio correlated with a substantial 2.67% decline in education service CPI and a 2.15% reduction in housing rents and deposits. This significant stabilization stems from distinct demand patterns within immigrant communities, who typically exhibit lower demand for high-cost private education and housing in premium school districts compared to domestic families.
Understanding the Dual Mechanism: Supply and Demand
The price-stabilizing influence of immigration operates through a dual-channel mechanism involving both the supply side and the demand side of the economy.
1. The Labor Supply Effect: Easing Cost Pressures
The primary driver for price reductions in services like personal care and public amenities is the augmentation of the labor force. Immigrants often fill vacancies in low-skilled or physically demanding jobs that face a shortage of domestic applicants. By increasing the supply of workers in these sectors, immigration helps moderate wage growth in those specific roles, which constitutes a major cost component for service businesses. This reduction in labor cost burdens allows businesses to maintain or even lower prices, passing the benefit on to all consumers.
2. The Demand Composition Effect: Reshaping Market Pressures
Immigration also influences prices by altering the overall composition of demand within a region. As the report highlights, immigrant households often have different consumption priorities. Their typically lower propensity to invest in expensive private tutoring (hagwons) or to compete for housing in elite school districts acts as a moderating force on prices in those hyper-competitive markets. This shift in demand composition helps dampen inflationary spikes in sectors that are major household expenses for domestic residents, leading to broader price stability.
Minimal Wage Impact and Enhanced Household Purchasing Power
A critical concern in public discourse is whether immigration suppresses wages for domestic workers. The KIET study addresses this directly, finding no significant negative impact on the real wages of native workers, including those in middle- and low-skilled positions. This is largely because immigrants frequently enter labor market niches that are experiencing shortages, taking on jobs that domestic workers are increasingly reluctant to accept. Thus, they often complement rather than directly compete with the existing workforce.
Importantly, the study concludes that the real purchasing power of domestic households, especially those with lower educational attainment (high school diploma or less), has been enhanced by immigration. The logic is straightforward: while nominal wages may remain steady, the effective value of each unit of currency increases when the cost of essential services like housing, education, and personal care becomes more affordable. Household budgets can stretch further, increasing their real standard of living without a corresponding rise in income.
Policy Implications and Future Considerations
Based on these findings, KIET advocates for a more strategic and nuanced approach to immigration policy. The report suggests two key recommendations:
Diversifying Labor Supply Pathways: Policymakers should consider broadening the channels for legal labor migration. One promising avenue is better utilizing international student populations, creating seamless pathways from education to employment in sectors with persistent labor shortages. This approach can provide a more stable and integrated source of skilled and semi-skilled labor.
Tailored and Regionalized Policies: A one-size-fits-all national immigration policy may be inefficient. The report emphasizes the need for policies that account for regional and industrial heterogeneity. Labor needs in manufacturing hubs like Pohang or Hwaseong differ vastly from those in service-oriented capitals like Seoul. Policies should be adaptable to local economic conditions to maximize benefits and minimize disruptions.
KIET also advises caution, noting that the potential for unexpected side effects requires ongoing scrutiny. While the aggregate impact is positive, follow-up research must thoroughly review possibilities such as intensified competition in specific local job markets or strains on very localized public services. Continuous monitoring and flexible policy adjustments will be essential to harness the economic benefits of immigration while ensuring social cohesion.
In conclusion, the KIET report provides robust evidence that immigration serves as a powerful economic stabilizer. By increasing labor supply in key service sectors and moderating demand in high-inflation areas like education and housing, immigrant inflows help control the cost of living. This process strengthens the real purchasing power of domestic households and does so without the detrimental wage effects often feared. The findings argue for a shift in perspective—viewing immigration not as a burden on the economy, but as a vital contributor to price stability and broader economic resilience.
