Answer:
free trade area
Step-by-step explanation:
There are four main types of economic integration models between countries:
- Free trade area: countries involved remove all trade barriers between them but are free to set trade policies with other countries, e.g. former NAFTA, now USMCA.
- Customs union: trade barriers are eliminated between members and all participating members agree to a common trade policy with non-member countries.
- Common market: similar to customs union but includes free movement of labor and capital.
- Economic union: a customs union that advanced into a political union, e.g. EU.
