“1. There is always full employment through price flexibility. Inputs can move freely within countries between technologies and commodities, which means that labour can move without any costs involved between two types of production (say farming and manufacturer). Capital can also move freely (it is assumed to be ‘malleable’).As Mitchell notes, the case for free trade was questioned even within neoclassical economics by the 1980s with the so-called “New Trade Theory,” which tried to model the reality of increasing returns to scale and imperfect competition.
2. Perfect competition exists in each country, which means that input suppliers cannot influence the price they receive and firms cannot influence the price they sell products at. The pure free market demand and supply forces determine prices.
3. Both countries have identical production technology which means that each nation can produce a given output of a particular commodity with the same capital and labour inputs should they choose.
3. There are constant returns to scale in production in both countries, which means that if the inputs of labour and capital are doubled, output will double.
4. The two commodities in question are produced using different technologies (different ratios of labour and capital), which means that a nation with lots of capital might be better placed to produce the more capital intensive good.
5. Inputs cannot move freely between countries, which means that capital cannot move freely.”

Of course, had neoclassicals bothered to take seriously the Post Keynesian critique of free trade, they would have known free trade theology was nonsense well before the New Trade Theorists, such as, for example, through the following Post Keynesian work:
