I recommend a new blog from Liz Stanton, Public Goods: The economics of climate, equity and shared prosperity. Stanton is "a senior economist with the Stockholm Environment Institute-U.S. and a research fellow at the Global Development and Environment Institute (GDAE) of Tufts University." I know her because we were in economics grad school together a few years back. Both of us came to economics late in the game, after we'd already completed our unrelated undergraduate degrees, for similar reasons–we both had developed a passion for sustainable agriculture, and decided we wanted to understand why our economic system seems so hell-bent on undermining sustainable endeavors, instead so richly rewarding corporate industrialization of every last inch of the Earth. In my case, I realized I just didn't want to become "an economist" and work in the field for the rest of my life, so I took my master's degree consolation prize and dropped out of the PhD program. Liz, with much more fortitude than I'll ever have, stuck it out and is clearly doing good things in the profession. That's one big loss for sustainable farms (she briefly had a small farm in California before turning to economics) and one big gain for economics and the rest of us interested in that far-reaching realm.
It's a brand new blog, so here's your chance to get in on the ground floor and enable yourself, years down the road, to say, "yeah, I was reading Public Goods before it became so popular."
