Is “Globalization” the Main Cause of Wage Inequality?

Trump, the new president of the United States, won the election victory for the reason of meeting the needs of the poor against globalization, which shows that anti-globalization is very popular in the United States. Is Globalization the main cause of rising wage inequality ?There are many theoretical and empirical literature on the relationship between globalization and wage inequality. This paper discusses the development of the theory in the past ten years, mainly discussing the trade model based on matching. Different scholars assume different scenarios, modify the models and get different conclusions. Matching can take a variety of forms. Workers can be matched with firms, with sectors, with managers, or with capital equipment, and the consequences of trade for wages depend on these particulars.
