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.

The Economics Of Dueling POLITICAL VIEWSThere seems to be a disturbance on the steps of the Shady Valley City Hall. Why it's the twins, Donna and Rhonda, engaged in yet another of their long-running, and overly heated, political arguments. Donna, you see, is a devoted Democrat and Rhonda is a rigid Republican. They haven't found much to agree on since, well, come to think of it they've never agreed on anything. In their current debate, Donna is making a strident case for stricter regulation of the banking industry and Rhonda is championing the virtues of free enterprise. I had better hitch up my jogging pants and intervene before their argument comes to blows -- again. While I do, let's ponder the source of differing political views.
