One of my current projects is to produce educational videos on economics, and post them to YouTube. Here are some of my latest videos [feed subscribers: click through to see the videos]:
In this video, I highlight the similarities between consumer theory and producer theory in an effort to make the isocost-isoquant graph intelligible.
This video takes a more technical approach, going from a Cobb-Douglas production function to the implied cost function.
This is just the start of the videos on producer behavior. Since last time, I have also made some videos on compensating variation, equivalent variation, elasticities, and using calculus on these topics. Feel free to explore my channel to see what else I have done.
