The problem: Answer a question about this article:
The free trade spirit of the time received a strong augmentation through the development of a modern, effective stock market in the Low Countries. The Netherlands has the oldest stock exchange in the world, founded in 1602 by the Dutch East India Company. While Rotterdam has the oldest bourse in the Netherlands, the world's first stock exchange – that of the Dutch East-India Company – went public in six different cities. Later, a court ruled that the company had to reside legally in a single city, so Amsterdam is recognized as the oldest such institution based on modern trading principles. While the banking system evolved in the Low Countries, it was quickly incorporated by the well-connected English, stimulating English economic output.
Which city did the Dutch East-India Company decide to reside in after a court decided they could legally only operate in one city?
****
The answer: Amsterdam

Such strategies, which minimize the maximum loss for each player, are called optimal. Von Neumann showed that their minimaxes are equal (in absolute value) and contrary (in sign). Von Neumann improved and extended the minimax theorem to include games involving imperfect information and games with more than two players, publishing this result in his 1944 Theory of Games and Economic Behavior (written with Oskar Morgenstern). Morgenstern wrote a paper on game theory and thought he would show it to von Neumann because of his interest in the subject. He read it and said to Morgenstern that he should put more in it. This was repeated a couple of times, and then von Neumann became a coauthor and the paper became 100 pages long. Then it became a book. The public interest in this work was such that The New York Times ran a front-page story. In this book, von Neumann declared that economic theory needed to use functional analytic methods, especially convex sets and topological fixed-point theorem, rather than the traditional differential calculus, because the maximum-operator did not preserve differentiable functions.

What von Neumann work was published in 1944?
Answer: Theory of Games and Economic Behavior
