Unger has presented a number of general institutional proposals that aim to restructure the world trade regime and introduce new alternatives in the market economy. For international and global trade, Unger calls for the need to experiment with different property rights regimes, where multiple forms will coexist in the same market system and not be tied to individual property rights and contractual labor. Generally, rather than maximizing the free trade as the goal, Unger sees the need to build and open the world economy in way that reconciles global openness with national and regional diversification, deviation, heresy, and experiment, where the idea is to support alternatives by making the world safer for them. For national economies, he rejects the need to require the free flow of capital, for there are times when it may be necessary to restrict capital flows. Rather, he puts the emphasis on the free flow of people. Labor should be allowed to move freely throughout the world.
