Thumbs Up?

It has been a while since I reported on interesting trends in the data from my YouTube channel. One trend that caught my eye is that some videos receive many more ratings than others. I knew that my video on budget constraints had received the most ratings (183 positive ratings to date), but were there other videos that induced people to click that thumbs up button?

To find out, I looked at the ratings for all of my videos that have 5000 or more views (37 of them). Once you look at the data, it turns out that 5 videos have a lower view-per-positive-rating ratio than my budget constraint video. In case you're wondering what these videos are, here's the list with views per positive rating in parentheses:
  1. (78.91) Video 43: Pareto Efficiency and the Edgeworth Box.
  2. (81.23) Video 40: Normal Form Games
  3. (87.94) Video 44: The Coase Theorem and the Edgeworth Box.
  4. (99.38) Video 37: Basics of Edgeworth Box Economies.
  5. (99.40) Video 16: Compensating and Equivalent Variation.
It is interesting that my endowment economy videos have done so well compared with the others on my channel. The average views-per-positive-rating among videos of mine that have 5000 views ore more on my channel is 205.62. By this measure, these videos are more than twice as "good" as the average "popular" video on my channel.
