POSITIVE ECONOMICS: The branch of economics that tries to explain the way the economy actually operates. It is the application of the scientific method and the process of testing hypothesis. A positive statement can be refuted by looking at the real world, that is testing hypotheses. Positive economics is the consequence of applying the scientific method to economic phenomena. This term should be compared and contrasted with normative economics, which says the way the world should be.

MARGINAL REVENUE, PERFECT COMPETITION The change in total revenue resulting from a change in the quantity of output sold. Marginal revenue indicates how much extra revenue a perfectly competitive firm receives for selling an extra unit of output. It is found by dividing the change in total revenue by the change in the quantity of output. Marginal revenue is the slope of the total revenue curve and is one of two revenue concepts derived from total revenue. The other is average revenue. To maximize profit, a perfectly competitive firm equates marginal revenue and marginal cost.

Packing Up For MIGRATIONThe quiet, peaceful town of Shady Valley has always been a great place for a pedestrian to wander through the workings of the economy. I'm afraid, though, that it's about to end. I've been offered another job -- an opportunity to wander around the streets of the distant mecca of Shady Lane to search out the mysteries of plant pathology. In Shady Lane, the sidewalks are smoother, the crosswalks are better, and the pay is much more lucrative. However, in that Shady Lane is in another time zone and several states away, migration would be my last topic of the day. There's a lot to be gained from this potential relocation of my residence, but it's not without cost. While I ponder this decision, perhaps you can help out by considering the topic of migration.
