Arguments for free trade?
Knowledge sharing. Big multinational corporations have expertise in fields that local firms lack. When these global concerns have access to smaller businesses partnerships are formed and the local businesses benefit from the training they provide. These new methods encourage the local smaller businesses to grow.
Intellectual property theft. Inconsistencies in patent protection and laws governing technological innovation often occur when free trade is established. A more fertile environment for IP theft occurs especially when the agreement is formed with developing nations.
Outsourcing. Imports become cheaper once tariffs and duties are lifted. Once areas start importing goods local businesses cannot compete and are forced to move jobs with a lower cost of living in order to reduce manufacturing costs. This creates unemployment in the local business’ area.
