But that' s an underestimate, because it doesn't count the basic biology and the basic science, which is all publicly funded. So if you get a realistic amount, it' s a very high percentage that's publicly paid anyway. Then all the motivation for monopolistic pricing would be gone, and there'd be a huge welfare benefit to it. There's no justifiable economic motive for not doing this. There's some economic motive, profit, but it is an effort to impede growth and development.
TRIMs are a little more subtle.
What they require is that a country cannot impose conditions on what an investor decides to do. Suppose General Motors, let's say, decides to carry out outsourcing, to have parts made in some other country with non-union cheap labor, and then send them back to General Motors. Well, the successful developing countries in Asia, one of the ways they developed is by blocking that sort of thing, by insisting that if there was foreign investment, it had to be done in a way that was productive for the receiving country. So there had to be technology transfer, or you had to invest in places they wanted you to invest in, or some proportion of the investment had to be for export of finished goods that made money. Lots of devices like that.
