End of Semester Project
Write an essay (8–10 pages) and deliver a presentation (30 minutes) on an e-commerce-related topic you think is interesting. I can imagine three types of projects (but there could be others.)
- Describe an online market or industry
- Offline antecedents.
- What's new / different.
- Economic issues-This discussion should be informed by economic models you see in this course or others.
- Ask a question, gather data, analyze data, and then answer your question.
- How does the time that an auction ends on eBay affect the revenue of the seller?
- What happened to newspaper circulation in a city when Craigslist entered that city?
- Give us a preponderance of useful facts.
- For example: How much price variation is there within titles for used books? Do the title's characteristics seem to matter? Does it vary across used book listing sites?
