Money as a Weighted Aggregate
• The Bank of Canada’s money supply measures are
‘simple-sum’ indices,
M = x1 + x2 + … + xn ,
where xj is one of the n monetary components of the
monetary aggregate M
• Weighted monetary aggregates (such as the ‘Divisia’)
seem to predict inflation and the business cycle
somewhat better than the Bank’s aggregates
