When a popular comedian announces a tour, tickets often sell out quickly. However, it is quite common for the tour coordinator to later announce additional shows in the form of matinees and late-evening performances. Why would the tour coordinator include unpublicized additional shows in the tour schedule? Additional shows create extra capacity and increase the tour's price elasticity of supply. People who purchased a ticket consider the comedian's show to be an inferior good. The tour coordinator knows that the price elasticity of demand for tickets is perfectly elastic. Attendees to the shows consider many other comedians' performances to be close substitutes.
Additional shows create extra capacity and increase the tour's price elasticity of supply.

You are a small business owner preparing to launch your first ad campaign to attract new customers, and must decide whether to learn about advertising yourself or hire a professional to launch the campaign. The campaign will last three months. If you hire a professional, you'll have to pay them a lump sum of $1,000 for the entire campaign. But if you decide to do it yourself, you'll take a course that costs $200 to introduce you to the skill. You'll also pay an employee $340 per month to work some of the hours you normally work while you manage the campaign. Would it be better to hire a professional rather than doing the campaign yourself? Yes, because your economic surplus is $220. Yes, because your full set of costs is only $540. No, because the benefit of not having to do it yourself is greater than the cost of the professional. No, because you can increase your economic surplus if you do it yourself.
Yes, because your economic surplus is $220.
Which statement is TRUE?
You can acquire both inputs and final goods and services in markets.
Why might you underestimate the increase in market quantity demanded when you lower your price? You may not take into account potential new customers attracted by the lower price. Some of your current customers may switch to a rival's product, so a drop in price doesn't produce any additional sales. Lowering the price only increases the quantity demanded for inferior goods. A price reduction increases the quantity demanded for individuals but not for the entire market.
You may not take into account potential new customers attracted by the lower price.
