Well, the unemployment numbers matter, as do other economic indicators (which, for the week, were not nearly as bad as the monthly employment report).
It's very hard to know what to say about the week's developments in the budget/debt limit negotiations. We'll likely only know whether things that happened this week mattered well after the fact.
I think I'll put Libya on the list this week.
Also, we had news of a dramatic drop in immigration from Mexico over the last couple of years. That certainly matters quite a bit.
What am I missing? What do you think mattered this week?
