Trade boosts income for all, without widening inequality gap over time.
Trade has a positive impact on a country's income and does not increase income inequality in the long run. By using geographic characteristics as a tool, researchers found that more trade leads to higher real income for countries over time. The benefits of trade are spread across different income levels, suggesting that trade integration is important for long-term development. The study confirms that the positive effects of trade on income are not influenced by other factors related to geography.
