The whole global labour force is represented on the horizontal axis. Workers at home are tallied from the left, while those working abroad are counted from the right. The marginal product of labor in the House is represented by the left vertical axis; the marginal product of work overseas is represented by the right vertical axis. At first, we presume that there are people working from home, as well as abroad employees. When this distribution is used, the actual wage ratio will be lower than in France (score C) when compared to other nations (score B). If workers are free to travel to the country that employs them, The greater the real pay, the more people will migrate from home to abroad until the real salary reaches L1O*, OL1. Initial employees are permitted to work in the country, and workers are permitted to work overseas. Workers move from home to abroad until they are employed both at home and abroad and their pay are reasonable. L2O * OL 2 L1O * OL1 equilibrium The ultimate global workforce allocation will include both native and foreign personnel (point A).

Migration of 3 labors from home country causes the actual wage rate to converge. Real earnings grow in France but decline in the rest of the world. It boosts overall world production. From to, foreign production increased by region below its marginal product curve, while domestic output decreased by region under its marginal product curve. We can see in the image that the foreigner's profit exceeds the House's loss by an amount equal to the region of color ABC in the image. Despite this benefit, some persons are negatively impacted by this alteration. Those who work from home first will earn greater real salaries, whereas those who work overseas initially will earn lower real wages. The benefit...
