摘要：We analyse the optimal composition of a committee comprising members that have private information and represent constituencies of different economic sizes. ‘Proportional representation' - i.e. each constituency represented proportionally to its economic weight - seems intuitively appealing, but as we demonstrate, the optimal committee composition is more complex. We show that representation in a committee depends also on (i) the ‘intrinsic' uncertainty of the available data, (ii) constituency's degree of sectoral specialization, and (iii) the extent to which economic developments are correlated between constituencies.
