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).

Exports and Imports

- Exports are goods and services produced by the domestic economy and purchased by the foreign sector.
- Imports are goods and services produced by the foreign sector and purchased by the domestic economy.
- Exports are the green flow coming from the foreign sector and joining GDP before reaching the business sector.
- Imports are the green flow leaving the consumption, investment, government purchases stream and going to the foreign sector.
- Note that the physical flow of production (exports and imports) moves in opposite direction as the green payment flows.

LONG RUN, MACROECONOMICS In terms of the macroeconomic analysis of the aggregate market, a period of time in which all prices, especially wages, are flexible, and are able to achieve equilibrium levels. This is one of two macroeconomic time designations; the other is the short run. Long-run wage and price flexibility means that ALL markets, including resource markets and most notably labor markets, are in equilibrium, with neither surpluses nor shortages. Wage and price flexibility and the resulting resource market equilibria are the reason for the vertical long-run aggregate supply curve.

[What's This?]
Today, you are likely to spend a great deal of time waiting for visits from door-to-door solicitors wanting to buy either a T-shirt commemorating the first day of spring or a coffee cup commemorating last Friday (you know why). Be on the lookout for deranged pelicans.
