The provisions of the Convention cover a wide range of agricultural products, homelessness, industrial products, working conditions and digital commerce. Among the most important aspects of the agreement are improving U.S. dairy farmers` access to the Canadian market, guidelines for a greater proportion of automobiles produced in the three countries and not imported from other countries, and maintaining the dispute settlement system, which is similar to that contained in NAFTA.   But other economists, including Gary Clyde Hufbauer and Cathleen Cimino-Isaacs of the Peterson Institute for International Economics (PIIE), have pointed out that stronger trade generates benefits for the U.S. economy. Some jobs are lost because of imports, others are created and consumers benefit greatly from lower prices and often improved product quality. Your 2014 PIIE study on the impact of NAFTA revealed a net loss of about 15,000 jobs per year as a result of the pact – but gains of about $450,000 for each job lost, in the form of higher productivity and lower consumer prices. Some small businesses have been directly affected by NAFTA. In the past, large firms have always had an advantage over small businesses, as large firms could afford to build and maintain offices and/or production sites in Mexico, which avoided many of the old trade restrictions on exports. In addition, pre-NAFTA legislation provided that U.S. service providers who wanted to do business in Mexico had to establish a physical presence there, which was simply too expensive for small businesses. Small businesses were stuck, they could not afford to build, and they could not afford export tariffs either. NAFTA eliminated the competitive conditions by giving small businesses the opportunity to export to Mexico at the same costs as larger firms and removing the requirement that a company establish a physical presence in Mexico to do business there.
The lifting of these restrictions meant that large new markets were suddenly open to small businesses that had previously done business only in the United States. This was considered particularly important for small businesses that produced goods or services that had matured in the United States.
