Globalization has become a widely used term to describe the forces knitting economies closer together. For the United States and Mexico, it’s just a new word for an old phenomenon. The two economies—one highly advanced, the other still developing—have for decades been on a path toward ever greater integration.

The U.S. is Mexico’s top trading partner by far. About 88 percent of Mexico’s exports go to the U.S., and 56 percent of its imports come from U.S. sources. At the same time, 14 percent of U.S. exports go to Mexico and 11 percent of imports come across the Rio Grande. Perhaps more important, U.S.–Mexico trade has grown exponentially since the signing of the North American Free Trade Agreement (NAFTA), growing from $89.5 billion in 1993 to $275.3 billion in 2004, a threefold increase.

Americans are the biggest investors in Mexico, further evidence of NAFTA pulling the two countries together. Since 1994, the U.S. has accounted for 62 percent of all foreign direct investment in Mexico.

The two economies are also linked by the flow of Mexican immigrants to the U.S. and the remittances they send back home to their families. The approximately 10 million Mexican nationals who reside in the U.S. sent back an estimated $20 billion in 2005, an amount equivalent to 3 percent of Mexico’s GDP.

The U.S. and Mexican economies have become increasingly synchronized. The coincident indexes for economic activity for both countries show that the degree of synchronization since 1993 is about a third higher than it was in 1980–93. The two economies now march almost in lockstep. [1]

The facts of U.S.–Mexico economic interaction are clear, but new questions continue to arise. How is China affecting trade between the countries? What has been the impact of NAFTA on Mexico’s economic growth, specifically on regional wages? Is the maquiladora industry tied to the U.S. business cycle? Are remittances reducing poverty levels in Mexico? What skills does the typical Mexican immigrant bring to the U.S.?

In November 2005, researchers from the U.S. and Mexico gathered in Houston to address these issues at a Dallas Fed conference, “The U.S. and Mexico: Are We Still Connected?” The presentations pointed to even greater interdependence for the two economies, a conclusion in sync with the worldwide trend toward increasing globalization.

U.S.–Mexico Trade
Mexico opened its economy to trade in two important steps: joining the General Agreement on Tariffs and Trade in 1985 and signing NAFTA in 1994. Reducing trade barriers represented an epochal change in Mexican policy, and it has brought a sustained increase in the inflow of foreign direct investment, made the country more competitive and insulated it against external shocks.

How have two decades of market opening impacted Mexicans’ pay? Daniel Chiquiar, a researcher from Banco de México, considered the role of trade in changing the distribution of wages in Mexico.

Several economic geography models have noted that Mexico’s trade liberalization had dramatic impacts that differed greatly by region, especially in manufacturing. The traditional Mexico City factory belt, located in the middle of the country, was optimal for a closed economy. After 1985, central Mexico lost at least some of its advantage. Led by maquiladora expansion, manufacturing employment and wages grew sharply in the states close to the U.S., and these gains came at the expense of the center of the country (Chart 1).

Chiquiar entered the debate by dividing Mexico into five regions and classifying them according to the strength of their ties to globalization through trade, migration and foreign direct investment. He treats globalization as a regionally heterogeneous shock to Mexico’s economy, with a slowly operating adjustment mechanism. Thus, globalization’s effects may be felt first and most strongly in regions with closer ties to the international economy.

Chiquiar showed that in regions with significant trade ties, wage inequality declined. Other regions, less tied to trade, saw inequality rise for reasons possibly unrelated to trade. Chiquiar concluded that further diminishing wage inequality will require the rest of the country to strengthen its linkages to the global economy.

Forming the backbone of U.S.–Mexico trade are programs of temporary imports to be re-exported, which bring parts into Mexico and return assembled products to the U.S. [2] Industrial goods make up 82 percent of Mexico’s exports to the U.S. and 91 percent of imports from the U.S. According to Enrique Dussel-Peters, economics professor at Universidad Autónoma de México, about half of U.S.–Mexico trade is considered intra-industry trade, again mostly due to temporary imports. Mexico’s intra-industry trade with the U.S. achieved its highest level in 2000 and has declined since then, while intra-industry trade with countries such as China is substantially lower.

These interconnections suggest the maquiladoras are closely tied to the U.S. industrial sector. Gustavo Félix Verduzco, professor at Universidad Autónoma de Coahuila, investigated the degree of synchronization between the U.S. business cycle and the maquiladoras, finding that the Mexican plants’ production and employment are sensitive to relative wages between the U.S. and Mexico and fluctuations in the U.S. economy.

Félix Verduzco also concluded that the economies of northern Mexico’s border states, where the maquiladora industry is concentrated, are more affected by U.S. business-cycle fluctuations than the rest of the country.

The U.S. has long been the chief trading partner for Latin America, and the rise of China as an industrial power has posed a new and significant threat to this relationship. U.S. imports from China grew 12 percent from 2000 to 2003, while U.S. imports from Latin America grew 2.7 percent, including 2.2 percent from Mexico.

José Ernesto López Córdova, an economist at the Inter-American Development Bank, conducted a study of several scenarios for the sensitivity of Latin American exports to competition from China in the U.S. market, particularly the likely response to changes in the prices of Chinese exports.

López Córdova estimated that a 1 percent decline in prices for Chinese exports to the U.S. would increase U.S. imports by 3.7 percent, while Latin American exports to the U.S. would drop 0.1 percent. The Latin American losses are concentrated in manufacturing, especially leather, textiles and apparel.

A scenario with a 20 percent revaluation of China’s currency results in Chinese exports to the U.S. falling 22.1 percent, or $43 billion, although overall U.S. imports fall only 1.7 percent, or $24 billion. An increase of 0.5 percent in Latin American exports to the U.S. partly fills the gap. South America gains the most, with leather, textiles and apparel again the sectors most sensitive to price changes.

López Córdova noted that China has been able to compete in the U.S. despite high tariff barriers and textile quotas, largely due to strong productivity gains. These productivity gains explain perhaps half of Latin America’s U.S. export losses and reinforce the need for regional fiscal, labor, energy and other reforms.

Sebastián Royo, associate professor of government at Suffolk University–Boston and director of Suffolk University’s Madrid campus, further discussed the need to reform political and economic institutions to take advantage of free trade agreements. He compared the integration of Spain and Portugal into the European Union (EU) with Mexico’s integration into the rest of North America under NAFTA.

Spain went from 78 percent of the EU’s average per capita GDP in 1990 to 98 percent in 2004, while Portugal went from 56 percent to 73 percent over the same period. Royo said that EU integration and Mexico’s NAFTA experience have been similar in that all three countries have been able to compete more effectively in international markets and confront serious economic crises at home. Although both treaties began as economic unions, the EU is different because it is based in a political union built around the principles of solidarity, which informs its distributive policies.

Both Spain and Portugal were traditionally emigrant countries, but European citizenship and free movement among member countries has ended some of the past discrimination against immigrants and reversed historical patterns. Indeed, these two countries have recently become net recipients of immigrants, perhaps offering lessons for Mexico.
