Trade is not necessarily a zero-sum game. Foreign trade, when conducted able-bodied, can be positive sum. Von Neumann was a mathematician, and he had used the mathematician's approach: take a simple example, solve it, and after that try to extend the solution en route for the more complex cases. Search en route for minimize his maximum loss.

All the rage the stock market, trading is a lot thought of as a zero-sum amusement. In A Discourse on Inequality18th-century French philosopher Jean-Jacques Rousseau famously sketched absent what is now called the stag-hunt problem.

Cost-effective competition is not a zero-sum amusement. It required organization and disciplined adroitness to track and kill large animals. Recognizing your edge is a condition to predicting whether trading will be pro table.
