Outline of Final Research Achievements

We investigated an exchange economy model with two kinds of infinitely divisible goods and two types of consumers to characterize stability and instability of competitive equilibrium by initial allocations to the consumers. We also developed an exchange economy model with two kinds of indivisible goods to conduct a double auction experiment with human subjects. In the middle of experiment, we changed the initial allocation from the stable case to the unstable case, and the other way around, and observed that price fluctuation is not so sensitive to the value of market excess demand. In addition, we examined an exchange economy model with three kinds of infinitely divisible goods and three types of consumers to characterize stable and unstable competitive equilibria in terms of parameters of utility functions of the consumers.
