A simple way to introduce this topic is to write the name of a popular brand on the white board. This could be a basic food item or popular drink or a consumer durable such as a smart phone. Then select a couple of volunteers and ask them how much they would be willing and able to purchase the good for. Then select a range of prices so that your students can calculate the consumer surplus for themselves. Then do the same thing but ask the volunteers to play the role of producers. Having completed this exercise you are now ready to continue with the lesson by providing your class with the attached class notes.</p><hr class="hidden"><div class="greenBg"><h3>Enquiry question</h3><p>Why is the benefit enjoyed by any community optimised where marginal benefit = marginal cost.

You ask for the menu which has no prices written on it. How much are you prepared (willing and able) to pay for a glass of lemonade? If the drink costs less than you are prepared to pay then you are lucky - the difference in the two prices represents your level of <em>consumer surplus</em>.</p><p>Similarly, as a producer of the good or service, if the product sells for more than you would otherwise be willing and able to supply the good for, the business enjoys a <em>producer surplus.</em></p><p>An explanation for these two terms can be found in the following video:</p><p style="text-align: center;"><iframe allowfullscreen="" frameborder="0" height="360" src="//www.youtube.com/embed/CtCfwMmzOBU" width="640"></iframe></p></div><div class="greenBg"><h4><em>Key terms:</em></h4><p><span lang="EN-GB" style="font-size:14.0pt;line-height:115%;font-family:"Times New Roman",serif;

For these train travellers their journey is essential and so they maybe willing and able to purchase a ticket for a price significantly above the market price. By contrast the passenger using the train during off peak times is reluctant to pay too high a price for his / her ticket because they have alternative options, including not travelling at all. This group of consumers will have a much smaller consumer surplus or perhaps no surplus at all. </span></p><p><span style="color:#FF0000;">Similarly for the train companies each journey comes with a very high fixed cost but low variable costs. The cost of operating the service for one additional passenger is almost zero. Therefore, the train companies have a producer surplus on every passenger after the firms costs have been covered.</span></p></div></section><div class="pinkBg"><h4><strong>6. Reflection activity: Producer and consumer surplus at auction</strong></h4><p>Watch the following short video, filmed at the famous Christie's auction house in London. Explain the concepts of consumer and producer surplus when a good is purchased at auction.</p><p style="text-align: center;"><iframe allowfullscreen="" frameborder="0" height="360" src="//www.youtube.com/embed/OYtN392gL9k" width="640"></iframe></p></div><section class="tib-hiddenbox"><div><p><span style="color:#FF0000;">Prior to placing a good at auction the seller sets a minimum price for the good that they are willing and able to sell the item for. Any price the seller receives above this price is producer surplus. Similarly the successful buyer decides before entering the auction the maximum price that they are willing and able to purchase the good for. Any price below this then represents their consumer surplus. In most instances therefore both the buyer and the seller will enjoy a surplus. </span></p></div></section><div class="greenBg"><h5><strong>7.
