Consumption in Economic Models Related to Large Games
956
Abstract
The paper contains a review of basic concepts associated with consumer's
demand in the setup appropriate to apply in economic models related to large
games. In particular, we study the demand functions which are well defined
also if some prices are zero, and their relations to utility functions and
indifference surfaces. In more detail we study Cobb-Douglas like and
''elliptic'' utilities, the last concept apparently not considered so far in
the literature.
Keywords :
demand function (correspondence), utility function,
Cobb-Douglas utility, elliptic utility, indifference (hyper)-surface, large
game.
