Institutionalist models of macroeconomic performance in advanced indus
trial countries focus on central bank independence. In newly industria
lizing countries, however, the behavioral authority of the central ban
k is a much more significant predictor of inflation than is legal inde
pendence, because laws there are not the source of central bank abilit
y to create or defend macroeconomic stability. Financial structures an
d the incentives they create for government politicians, private banke
rs, and industrialists explain cross-national variation in the interes
t and capacity of central banks in developing countries. The greater p
ublic sector deficits are, the weaker and/or more dependent private ba
nks are on state assistance; and the larger the portion of industry fi
nance covered by commercial bank loans or state credits, the less like
ly it is that there will be an authoritative, conservative central ban
k. Mexico, Thailand, Brazil, and South Korea are the four country case
s considered in depth.
