ELASTICITY AND DEMAND SLOPE: The slope of a straight-line demand curve, one with a constant slope, has constantly change elasticity. No two points on a straight-line demand curve as the same elasticity. The point of intersection between the demand curve and the vertical, price axis is perfectly elastic (E = ∞). The intersection point between the demand curve and the horizontal, quantity axis is perfectly inelastic (E = 0). The exact middle, or midpoint, of the demand curve is unit elastic (E = 1). The segment between the midpoint and the price-axis intercept is relatively elastic (1 < E < ∞). The segment between the midpoint and the quantitY-axis intercept is relatively inelastic (0 < E < 1).

NET-EXPORT EFFECT A change in aggregate expenditures on real production, especially net exports from the foreign sector, that results because a change in the price level alters the relative prices of exports and imports. The net-export effect, also termed the international-substitution effect, is one of three effects underlying the negative slope of the aggregate demand curve associated with a movement along the aggregate demand curve and a change in aggregate expenditures. The other two are real-balance effect and interest-rate effect. The net-export effect is somewhat analogous to the substitution effect underlying the negative slope of the market demand curve.

Today, you are likely to spend a great deal of time watching the shopping channel hoping to buy either a black duffle bag with velcro closures or any book written by Isaac Asimov. Be on the lookout for mail order catalogs with hidden messages.
