It has become common over the last decade for electoral systems
to combine two
electoral formulas
for the choice of
candidates
for a representative
assembly
. New Zealand,
for example, has adopted a system which combines a single member
plurality system
with a
list system
of proportional
representation (see
mixed member proportional
). While most mixed systems aim to achieve proportional
outcomes—the vote share of a party is matched by a
similar share of seats in the assembly—this is not
always the case. Some mixed systems such as that used
for the Japanese House of Representatives produce outcomes which
favour large parties. These systems are sometimes
called mixed member majority systems (MMM). See also
