DEMAND ELASTICITY AND TOTAL EXPENDITURE: The notion that price-induced changes in total expenditure for a good (price times quantity) depends on the relative price elasticity of demand. In particular, for relatively elastic demand (1 < E < ∞) changes in price cause total expenditure to change in the opposite direction. An increase in price causes total expenditure to fall and a decrease in price causes total expenditure to rise. For relatively inelastic demand (0 < E < 1) changes in price cause total expenditure to change in the same direction. An increase in price causes total expenditure to rise and a decrease in price causes total expenditure to fall. For unit elastic demand (E =1) price changes do not cause any change in total expenditure. Total expenditure is the same whether price increases or decreases.

PUBLIC CHOICE The study of collective decisions made by groups of individuals, especially those decisions made by government organizations. As the name suggests, public choice is primarily the study of how choices (decisions) are made by the public (government) sector. Such choices are made, in principle, on behalf of the public or all members of society, to correct market failures or imperfections in the private sector. However, in that the world is imperfect on all fronts, the government sector also comes up short in many cases, with inefficient imperfections due to election seeking politicians, ignorant and abstaining voters, special interest groups, and government bureaucracies.
