Query: On the Uniqueness and Stability of the Equilibrium Price in Quasi-Linear
  Economies   In this paper, we show that if every consumer in an economy has a
quasi-linear utility function, then the normalized equilibrium price is unique,
and it is locally stable with respect to the t\^atonnement process. If the
dimension of the consumption space is two, then this result can be expressed by
the corresponding partial equilibrium model. Our study can be seen as that
extends the results in partial equilibrium theory to economies with more than
two dimensional consumption space.
