Abstract: We analyse how corporate debt structure can shape the transmission of monetary policy in a general equilibrium model. We endogenise firms’ choice between bond and loan financing in a dynamic setting, building on the analytical framework of the financial accelerator and show that the corporate structure of firms is not irrelevant. We assume that banks have an informational advantage over other market participants in evaluating firms’ projects. This results in a lower cost of bank finance compared to market finance in a steady state, given institutional factors and market size. Over time, shocks to the cost of finance or liquidity shocks feed back into the dynamics of firms’ net worth, investment and output. In our framework, monetary policy can have asymmetric effects. On one hand, higher banks’ refinancing costs due to more stringent conventional monetary policies have a greater impact on firms that cannot easily substitute loans for bonds. Firms with easier access to the bond market have a competitive advantage over firms that can only rely on bank financing. On the other hand, shocks that increase the liquidity in the bond markets, such as unconventional monetary policies, benefit firms with a more diversified corporate debt structure. From this perspective, the development of bond markets can have important macroeconomic implications for building resilience.
