An analysis using the kinked-demand curve to explain rigid prices often found with oligopoly. The kinked-demand curve contains two distinct segments--one for higher prices that is more elastic and one for lower prices that is less elastic. Key to this analysis is that the corresponding marginal revenue curve contains three segments--one associated with the more elastic segment, one associated with the less elastic segment, and one associated with the kink. A profit-maximizing firm can then equate marginal cost to a wide range of marginal revenue values along the vertical segment of the marginal revenue curve. This suggests that marginal cost must change significantly before an oligopolistic firm is inclined to change price.

The first stop for any pedestrian on a leisurely stroll through the busy economic streets of Shady Valley is Scarcity Stan's Ye Olde Bakery Shoppe and Confectionery Palace. The most noted pastry on Scarcity Stan's list of delectables, wedged between his mouth-watering apple danishes and scrumptious jelly donuts, is economic pie. My mouth waters with the thought.

Economic pie isn't like other donuts, cakes, and confectioneries with their gobs of sweetness, but very little nutritional sustenance. In fact, given that it refers to the sum total of the economy's resources and productive activity, economic pie is filled to the brim with sustenance. Unfortunately, Scarcity Stan and the congregation of people we call society, has only one economic pie, and while it's pretty large, it's never quite as big as we would like.

Today, you are likely to spend a great deal of time at a going out of business sale trying to buy either 500 feet of telephone cable or a package of 4 by 6 index cards, the ones with lines. Be on the lookout for crowded shopping malls.
