There is a very good article (free content at this writing) in today's issue of The Wall Street Journal. It should have high interest for students, given the subject matter and it is loaded with applications for micro concepts and even for the micro review before teaching macro.
The article is about declining gross sales for concert tours. There was a significant drop this year. This may not be surprising. My guess is that students and teachers would both say that concert prices are highly elastic. Given the times, it would only seem logical that ticket sales would drop. However, early in the article there is a statement that grosses had increased each of the last eight years. That includes 2008 and 2009. The statement goes on to say that the number of tickets sold held roughly even despite rising ticket prices. That would indicate characteristics of a good that is highly inelastic.
We know that elasticity can change. But we can go into the reasons for the change. The article gives us room to pursue both income effects and substitution effects. Of particular interest is the idea that older groups tend to be bigger draws than newer groups. Given the possible fan base, this would seem to indicate that it is people with more disposable income that are buying the tickets. That does not mean that only older fans go to see older groups, or that younger acts don't attract older fans, but there may be factors to consider in a discussion.
The article also has some useful graphics, a slideshow, and a video (downloadable) to accompany it. I suggest you give it a look.
