I'll list corrections to the main pdf document here and incorporate them into the pdf document from time to time.
2008 A2: (a) Or rather, "Not unless v3 is zero"
2009 B15: (a) Indirect utility should be V = ln(p2/p1) + (y-p2)/p2
2010 B10: (a) I've given the opposite condition, so it should say alpha not equal to 3 or -2 and beta can be any value
2010 B13: very last bit should be n times what I said, so (3n/8)var(a_i)
