Wonk Blog's Brad Plumer calls attention to a NBER paper (nber.org/papers/w19027) on corruption in state government that draws a correlation between distance from the capital and the main population center and corruption. I am not particularly convinced of the correlation and the trend line plot ...

As you might have already guessed, the Tyrrell is not short of tyrannosaurs and this blog is going to be heaving with them by the end. I mean, this is the second post and I’m still on all the life reconstructions! (and no, we’ve not got to the murals yet, let alone the actual mounts and specime ...
