📖 I’m 4% done reading Economy, Society, and Public Policy by CORE Team

Read sections 1.0-1.3. I’m loving the graphs, charts, videos, and supplementary interactive material they’re including in the book. It’s completely fascinating and quite a different reading experience on a computer versus either paper or e-reader.

Having immediate access to data like this make for a more interesting Economics experience.

I don’t think we have to go back even this far. If I recall correctly, even 150 years ago the vast majority of the world’s population were subsistence farmers. It’s only been since the 20th century and the increasing spread of the industrial revolution that the situation has changed:

Even England remained primarily an agrarian country like all tributary societies for the previous 4,000 years, with ca. 50 percent of its population employed in agriculture as late as 1759.

If you have never seen an ice-hockey stick (or experienced ice hockey) this shape is why we call these figures ‘hockey-stick curves’. ❧

I’m glad they’ve included an image of a hockey stick to provide the context here, but I’ve always thought of it rotated so that the blade was on the ground and the sharp angle of the handle itself indicated the exponential growth curve!
