Query: Money in Gas-Like Markets: Gibbs and Pareto Laws   We consider the ideal-gas models of trading markets, where each agent is
identified with a gas molecule and each trading as an elastic or
money-conserving (two-body) collision. Unlike in the ideal gas, we introduce
saving propensity $\lambda$ of agents, such that each agent saves a fraction
$\lambda$ of its money and trades with the rest. We show the steady-state money
or wealth distribution in a market is Gibbs-like for $\lambda=0$, has got a
non-vanishing most-probable value for $\lambda \ne 0$ and Pareto-like when
$\lambda$ is widely distributed among the agents. We compare these results with
observations on wealth distributions of various countries.
