What are the major features of Mercosur, CAFTA, and the European Union?

"The largest new trade agreement is Mercosur, which includes Peru, Brazil, Argentina, Uruguay, and Paraguay. The elimination of most tariffs among the trading partners has resulted in trade revenues that currently exceed $16 billion annually. Recent recessions in Mercosur countries have limited economic growth, even though trade among Mercosur countries has continued to grow. The newest free trade agreement is the Central America Free Trade Agreement (CAFTA) passed in 2005. Besides the United States, the agreement includes Costa Rica, the Dominican Republic, El Salvador, Guatemala, Honduras, and Nicaragua. The United States is already the principal exporter to these nations, so economists don’t think that it will result in a major increase in U.S. exports. It will, however, reduce tariffs on exports to CAFTA countries. Already, some 80 percent of the goods imported into the United States from CAFTA nations are tariff-free. CAFTA countries may benefit from the new permanent trade deal if U.S. multinational firms deepen their investment in the region. In 1993, the member countries of the European Community (EC) ratified the Maastricht Treaty, which proposed to take the EC further toward economic, monetary, and political union. Although the heart of the treaty deals with developing a unified European Market, Maastricht was also intended to increase integration among European Union (EU) members. The EU has helped increase this integration by creating a borderless economy for the 28 European nations. European Union member states have set up common institutions to which they delegate some of their sovereignty so that decisions on specific matters of joint interest can be made democratically at the European level. This pooling of sovereignty is also called European integration. In 2016, citizens of the United Kingdom voted to leave the European Union, a plan known as Brexit, which could take several years to occur. One of the principal objectives of the European Union is to promote economic progress of all member countries. The EU has stimulated economic progress by eliminating trade barriers, differences in tax laws, and differences in product standards, and by establishing a common currency. A new European Community Bank was created, along with a common currency called the euro. The European Union’s single market has created 2.5 million new jobs since it was founded and generated more than $1 trillion in new wealth. The opening of national EU markets has brought down the price of national telephone calls by 50 percent since 1998. Under pressure of competition, the prices of airfares in Europe have fallen significantly. The removal of national restrictions has enabled more than 15 million Europeans to go to another EU country to work or spend their retirement. The EU is a very tough antitrust enforcer; some would say it is tougher than the United States. The EU, for example, fined Google $2.7 billion for favoring some of its own services in its search results. Unlike in the United States, the EU can seal off corporate offices for unspecified periods to prevent destruction of evidence and enter the homes, cars, yachts, and other personal property of executives suspected of abusing their companies’ market power or conspiring to fix prices."
