Summary of the Selected Issues Paper on Australia: Macroeconomic Impact of Migration

Core Content

This paper examines the macroeconomic impact of migration in Australia, focusing on how migration affects output, employment, productivity, inflation, and housing prices. It highlights the increasing importance of migration in Australia's population growth due to declining natural increase and aging demographics. The study also explores the characteristics of migrants and their labor market outcomes, emphasizing the high educational attainment of migrants compared to the native population.

Main Points

1. Population and Migration Trends

• Australia has a population of about 26 million, with a high concentration in urban areas along the eastern and southern coasts.
• The median age is 37.5 years, and life expectancy is among the highest in the world.
• Migrants make up a significant portion of the population, with around a third of the population aged 15 and over being born overseas.
• Net overseas migration has increased significantly in recent years, especially after the pandemic, contributing to over 60% of population growth in the last decade.

2. Migration Characteristics

• Migrants in Australia are predominantly skilled workers and students.
• Migrants from main English-speaking countries tend to have higher labor force participation and employment outcomes.
• The share of tertiary-educated migrants in Australia is higher than in other OECD countries (around 60% vs. 40%).
• Humanitarian migrants and refugees make up a smaller share of migration flows.

3. Macroeconomic Impact of Migration

• GDP Growth: Migration is positively associated with GDP growth, with a 1.2% increase observed by the fifth year after a migration shock.
• Employment: Migration has a modest positive effect on employment, though not statistically significant.
• Inflation: Migration does not significantly impact inflation, with weak or no correlation observed in both headline and core CPI indices.
• Housing Prices: Migration is positively correlated with housing prices, though the effect is modest and only marginally statistically significant in the short term.

4. Event Study Analysis

• Three major migration surges (1988, 2008, 2017) were analyzed using event studies.
• GDP growth tends to decline after migration surges, likely due to external shocks such as the GFC and pandemic.
• Unemployment rates initially drop but then rise over time, with volatility influenced by specific events.
• Employment growth increases in the first two years post-peak and stabilizes thereafter.

5. Cross-Country Panel Analysis

• A panel of 34 OECD countries from 1995 to 2018 was used to assess migration's macroeconomic impact.
• Instrumental variable (IV) methods were applied to address endogeneity concerns, using migration from other countries as an instrument.
• Results confirm a positive effect of migration on output and employment, with no significant inflationary pressures.

Key Findings

• Positive Growth Impact: Migration is associated with higher GDP growth and employment, particularly in the long run.
• Limited Inflationary Pressure: Migration does not typically cause significant inflation, with the exception of housing prices.
• Housing Affordability Concerns: While housing prices rise in response to migration, the effect is small and may be due to structural supply shortages rather than migration alone.
• Labor Market Outcomes: Migrants generally have favorable labor market outcomes, especially in terms of participation and employment, though there are gender disparities, with migrant women facing lower employment rates due to unpaid work.
• Skill and Education Levels: Migrants are highly educated, often exceeding the education levels of the native population, which supports a more productive and dynamic labor market.

Conclusion

Migration plays a critical role in Australia's population and labor market dynamics. As natural population growth declines, migration is expected to become an even more significant contributor to economic growth and labor force participation. While migration has a positive impact on output and employment, its effects on inflation are minimal. Housing prices are affected, but this is likely due to structural supply constraints rather than migration alone. The paper underscores the need for policy measures to address housing supply and support migrant integration into the labor market.
