The “Norwegian model” allows Norway to participate in the EU`s single market through the European Economic Area, which includes respect for all four freedoms (including freedom of movement). They can be in the EU`s single market, but not in the EU, which is what Norway, Iceland and Liechtenstein are doing. There are EU-wide regulations covering a range of industries and products, from food standards and the use of chemicals to working hours to health and safety. This is an attempt to create a level playing field and an internal market; this does not happen in a free trade area. Customs unions and single markets are examples of further economic integration between countries The agreement may extend to some liberalisation of trade in services, but most free trade areas do not provide for the free movement of labour or capital. A free trade area is created when a group of countries meets and agrees not to impose tariffs or quotas on trade in goods between them. .
