Query: Theory of Quantum Games and Quantum Economic Behavior   The quest of this work is to present discussions of some fundamental
questions of economics in the era of quantum technology, which require a
treatment different from economics studied thus far in the literature. A study
of quantum economic behavior will become the center of attention of economists
in the coming decades. We analyze a quantum economy in which players produce
and consume quantum goods. They meet randomly and barter with neighbors
bilaterally for quantum goods they produced. We clarify the conditions where
certain quantum goods emerge endogenously as media of exchange, called quantum
commodity money. As quantum strategies are entangled, we find distinctive
aspects of quantum games that cannot be explained by conventional classical
games. In some situations a quantum player can acquire a quantum good from
people regardless of their strategies, while on the other hand people can find
quantum strategies that improve their welfare based on an agreement. Those
novel properties imply that quantum games also shed new light on theories of
mechanism design, auction and contract in the quantum era.
