Global migration affects the world economy in complex and diverse ways. This phenomenon can be viewed from several points of view, including contribution to the workforce, innovation, and cultural diversification. One of the most direct impacts is an increase in the workforce that is able to fill shortages in various sectors. Developing countries often welcome highly skilled immigrants, helping to meet increasing market demand. Second, global migration contributes to increased economic growth. When immigrants enter the labor market, they not only fill jobs but also create new jobs through entrepreneurship. Statistics show that immigrant entrepreneurs are often more innovative and willing to take risks in business. This is reflected in the large number of startups founded by immigrants, which have become important innovation centers in many developed countries. Furthermore, migration also strengthens remittances, the flow of money sent by immigrants to families living in their country of origin. These funds can help improve the quality of life and support the local economy. According to the World Bank, global remittances reach more than 700 billion USD annually, and it is an important source of income for many low-income countries. Migration also has significant social and economic impacts through the transfer of culture and the exchange of ideas. Various innovations and new business practices often originate from interactions between immigrants and local communities. This process encourages collaboration that often results in better products and services. However, migration also has challenges. Sometimes, the presence of immigrants can cause social tensions and competition in the job market. There are several cases where local workers feel threatened by the presence of immigrants who are willing to work for lower wages. This can result in anti-immigration policies that have a negative impact on social and economic integration. From a macroeconomic perspective, host countries often need to adjust fiscal and budgetary policies to deal with population increases. An increase in population can lead to greater needs for infrastructure, education and health services. Countries that succeed in managing migration effectively can reap benefits and increase competitiveness. Furthermore, global migration also affects the property and housing markets. Demand for housing often increases when immigrants come to an area. This can create a positive impact for property developers and investors, but it can also cause a spike in rental prices that impacts local residents. From a global perspective, migration brings many benefits, but also challenges that need to be managed wisely. Cooperation between countries and inclusive policies can help maximize the benefits of migration while minimizing adverse social impacts. Deep research and understanding of the effects of migration on the economy is essential to creating a win-win environment around the world.
