Here is a case which advanced students enjoy.
The hotlinks within the case go to pages on The Export-Import Home Page with more data on the topic (for example, letters of credit).
At the end are possible choices that will be offered by class members with hotlinks to the results of each choice.
An effective way of presenting the case is to access it through the web and project it to the front of the classroom. Scroll through slowly enough that all students can take notes. Perhaps you will ask students to take turns reading parts of the case aloud.
Doing it "live" allows the hotlinks to work in front of the classroom. Permission is granted to any instructor to use the case in this manner. (Be sure to use the "forward" and "back" buttons exclusively in the presentation (rather than links). Some of the links can take you to other topics.)
Note the case is copyrighted. Providing hard copies is limited to one per student, in classes where Export-Import is being used as a text, showing the copyright notice.
