How migration could make the world richer

Macroeconomic Impact of Migration

• Global GDP could increase by 50% to 150% if migration barriers were removed, potentially doubling world wealth annually.
• This potential gain exceeds the economic boost from removing all remaining global trade barriers, which would only raise GDP by up to 4%.
• Relocating just 5% of the workforce from poorer nations to richer ones would generate more economic value than eliminating all trade barriers.
• Labor productivity can increase by a factor of eight or more for workers moving from developing nations to developed ones without any inherent change in worker capability.
• Current estimates identify 270 million migrants worldwide, with another 750 million individuals indicating a desire to migrate if barriers were removed.

Migration Flows and Motives

• Approximately one-tenth of all migrants flee war or persecution; the vast majority move primarily for economic advancement.
• Remittances now account for over 10% of GDP in 30 countries and nearly one-third of GDP in nations like Tajikistan and Kyrgyzstan.
• By 2019, remittances surpassed foreign direct investment as the largest source of external financing for developing countries.
• Migration generates non-monetary benefits for origin countries through trade tie development, technology transfer, investment links, and the repatriation of skills by returning migrants.
• Economist Michael Clemens argues that no country has ever been developed by restricting the movement of its population.

Labor Market Dynamics and Integration

• Immigrants largely complement native workers rather than competing directly for the same positions.
• When migrants fill low-skilled roles, native workers frequently shift into higher-skilled, higher-paying occupations.
• High-skilled migrants disproportionately drive innovation, contributing significantly to patents, new products, and scientific breakthroughs.
• In the United States, immigrants or their descendants founded 45% of Fortune 500 companies, including major entities like Apple, Google, and Levi Strauss.

Public Perception vs. Reality

• Public opinion often overestimates migrant populations; in the US, the average citizen estimated 36% of the population was foreign-born, whereas the actual figure was 13.5%.
• Misconceptions also exist regarding unemployment, with the public believing immigrant unemployment rates are higher than those of native-born citizens, despite data showing the opposite in many cases.
• These distorted perceptions currently drive government policies that restrict immigration despite evidence of net economic benefits.

Policy Recommendations and Future Outlook

• Advocates suggest that policy reform need not imply "global anarchy" but rather the establishment of better-regulated, lawful pathways for migration.
• The focus is recommended to be on creating "better lawfulness" to facilitate the most productive investments available to the world's poor.
• Australia is cited as a comparative model, where a foreign-born population comprising nearly one-third of the total has supported steady economic growth for 28 years.
• The consensus among experts is that even modest regulatory improvements could unlock trillions of dollars in global economic value.
