If you ever wanted to understand deflation, and how it is effecting the economy, I have put together a comprehensive and in-depth lecture on the subject. My "Deflation 101" podcast explores what deflation is, why we are experiencing it, and why it is going to last for years to come.
I have also built a slide deck, with numerous charts, to accompany the podcast.
There is also an episode of the Optimistic Bear internet radio show that offers a primer on deflation. If you want to participate in the community discussion about this subject you can join the Deflation Study Group on LinkedIn.
