This paper examines the recent saving performance of the Chilean economy in
the light of its long-run (1940-96) trends. The first conclusion that can
be derived from the data is that most of the increase in private saving sin
ce the mid-1980s is due to business saving. Household saving turns out to b
e a stationary variable with zero mean. Since business saving has a unit ro
ot, households do nor seem to take the saving of firms into account when ma
king their own saving decisions. Within the theoretical framework of a mode
l of business investment with liquidity constraints, we estimate a VAR for
business saving, private investment, public saving and foreign saving (the
current account deficit). We are able to determine that business saving is
unaffected by public saving, but that, in the long run, foreign saving and
business saving are perfect substitutes. Private investment, business savin
g and foreign saving are jointly determined. The policy conclusions are tha
t policies that stimulate investment are likely to lead to an increase in p
rivate saving, that policies aimed at raising household saving will be inef
fective, and that increases in public saving are very powerful for increasi
ng domestic saving in the long run.
