We develop a tractable general equilibrium model that captures the interplay
between nominal long-term corporate debt, inflation, and real aggregates. We
show that unanticipated inflation changes the real burden of debt and, more
significantly, leads to a debt overhang that distorts future investment and
production decisions. For these effects to be both large and very persistent
it is essential that debt maturity exceeds one period. We also show that
interest rate rules can help stabilize our economy.
