I have no clue about deflation or inflation, but I like to read iTulip and Mish’s Global Economic Trend Analysis and Roubini’s blog. I will keep reading their stuff.
Eric Janszen has an interesting inflation/deflation theory, which he developed a few years ago and recently revised, and its based on what happened in the credit bubble of the Great Depression. The guy is simply briliant. It’s his KaPoom theory, and is worth a read.
