I usually don't buy popcorn when watching a movie, but I guess that if we apply the idea to an entrance fee and a cost per ride, at the same time having price discrimination for the elderly, then this model works. I have two questions though. First, would we discriminate for the elderly both in the entrance fee AND in the per ride fee? Or is that type of discrimination called something else? Second, you said that it is a simple exercise to determine the conditions for profitability, but I am lost. Can you help me get started?

Well, you can always pay to get into Disneyland and then ride no rides.

To your first question, it's not required.  Given your question, all we need is a two-part tariff and some form of consumer class-based price discrimination.  This would be present whether the class-based discrimination was on the entry fee, the per-use fee, or both.

Second question:  that might be difficult for me to do here.  What level are you coming at this concept from?  Are you just seeing price discrimination for the first time?

I didn't take that many undergrad econ courses (didn't take IO), but I did take graduate micro with MWG last semester.

It would probably be tough to make up for the lack of IO in a reasonable amount of space.  But if you're familiar with a textbook example of both 3rd-degree price discrimination and two-part tariffs, begin with a 3rd-degree problem and in place of the class-based pricing, insert a two-part tariff.  It should basically look like the simultaneous solving of multiple two-part tariff problems subject to one firm's constraints.

<p>Of course, I am only interested in instances where the combination of the two strategies ultimately lead to higher profits than if the monopolistic firm had used only one.</p>

Are there examples of strategies where a combination of third degree pricing and two-part tariffs are used together?
