For example, if a consumer consumes a banana, he/she gets 10 amounts of utility. So, let's do that. The marginal external benefit curve (MEB) is directly linked to the marginal social benefit curve (MSB). Voiceover: In all of our conversations about demand curves so far, I've been generally talking about price driving quantities. b. Next is a summary of the methods to calculate these costs. For example: Let's say a pair of pants is being sold for $50. - [Sal] Let's study the It is a pivotal economics concept in that companies must recognize that customers dont always value later units as much as initial units purchased.

Direct link to Vebjrn Tveiteras's post I would think that margin, Posted 10 years ago. In the move from Q1to Q2, private agents reduce their costs by f (they are producing less so costs should be less; f is the area underneath the marginal private cost curve between Q2andQ1) but also decrease their benefit by e+f (the area under the marginal private benefit curve between the two quantities of interest). The marginal benefit can be negative as after consuming a certain amount of product, a consumer will not want to take that product anymore. If the external benefit is included, the socially efficient output rises to quantity Q1. But you need to remember that the market price is set by the market leaders, not the consumers.
