Microeconomics is the study of markets and their participants, and macroeconomics is the study of whole economies. This means we need tools to analyse what is going on at a national level.

I have moved. I have started a weblog at another location. I hope what readers I have gained will pursue me to that halcyon shore.

I've made three posts of this ilk on my other site, and they do jar with what I'm doing there, so from now on my comment wars posts go here!

In other news, I'm a far better scholar than I was the last time I posted here, I have published a few defences of the Austrian school, and begun an exposition of the methods and claims of Austrians, namely praxeology and thymology. I look forward to seeing all three of you there!

So, come and find me!
