The Nordhaus hypothesis about the political business cycle asserts tha
t elected politicians have incentives to expand the money supply prior
to elections to stimulate the economy and thereby engineer their re-e
lection. Central bank independence is widely regarded as an institutio
nal solution to this problem. However, this solution works only if cen
tral bankers are not perfect agents of their political principals, per
haps because they are conservative (more inflation-averse). This artic
le proposes an alternative solution: political business cycles may be
obstructed by institutional checks and balances. The analysis applies
to the Deutsche Bundesbank and has implications for the institutional
structure of the future European Central Bank.
