GIFFEN GOOD: A rare type of good seldom seen in the real world, in which a change in price causes quantity demanded to change in the same direction (in violation of the law of demand). In other words, an increase in the price of a Giffen good results in an increase in the quantity demanded. The existence of a Giffen good requires the existence of special circumstances. First, the good must be an inferior good. Second, the income effect triggered by a change in price must overwhelm the substitution effect. A Giffen good is most likely to result when the good is a significant share of the consumer's budget.

Production
- The first unit of this lesson, Short-Run Production, begins our study by introducing a few basic concepts underlying production, especially short run, long run, fixed input, and variable input.
- In the second unit, Production Measures, we take a look the three standard measures of production -- total product, average product, and marginal product.
- The third unit, Product Curves, then presents graphical relations for these three measures -- total product curve, average product curve, and marginal product curve.
- In the fourth unit, Long-Run Production, we examine the role returns to scale play in long-run production.
- The fifth and final unit, Supply, then closes this lesson by previewing the importance of production to the supply decisions by firms.s

PERFECT COMPETITION, LONG-RUN PRODUCTION ANALYSIS In the long run, a perfectly competitive firm adjusts plant size, or the quantity of capital, to maximize long-run profit. In addition, the entry and exit of firms into and out of a perfectly competitive market guarantees that each perfectly competitive firm earns nothing more or less than a normal profit. As a perfectly competitive industry reacts to changes in demand, it traces out positive, negative, or horizontal long-run supply curve due to increasing, decreasing, or constant cost.
