With great wealth comes great pettiness. - Paul Krugman

The history of of the study of the location of economic activity is more like the story of geological thought about the shapes and location of continents and mountain ranges. The location of production is an obvious feature of the economic world. Indeed, I began to get interested in economics as a schoolchild by looking at those old-fashioned maps of countries that used picturesque symbols to represent economic activity: sheaves of wheat to represent agriculture, little miners' carts to represent resource extraction, little factories to represent industry, and so on. And yet there is almost no spatial analysis in mainstream economics.

I do not think that word “compromise” means what Mr. Ryan thinks it means. Above all, he failed to offer the one thing the White House won’t, can’t bend on: an end to extortion over the debt ceiling. Yet even this ludicrously unbalanced offer was too much for conservative activists, who lambasted Mr. Ryan for basically leaving health reform intact. Does this mean that we’re going to hit the debt ceiling? Quite possibly; nobody really knows, but careful observers are giving no better than even odds that any kind of deal will be reached before the money runs out. Beyond that, however, our current state of dysfunction looks like a chronic condition, not a one-time event. Even if the debt ceiling is raised enough to avoid immediate default, even if the government shutdown is somehow brought to an end, it will only be a temporary reprieve. Conservative activists are simply not willing to give up on the idea of ruling through extortion, and the Obama administration has decided, wisely, that it will not give in to extortion. So how does this end? How does America become governable again?

We’re living in a Dark Age of macroeconomics. Remember, what defined the Dark Ages wasn’t the fact that they were primitive — the Bronze Age was primitive, too. What made the Dark Ages dark was the fact that so much knowledge had been lost, that so much known to the Greeks and Romans had been forgotten by the barbarian kingdoms that followed.
