This thesis consists of four essays on the role of firm heterogeneity for
monetary policy transmission.
Firm Heterogeneity and Monetary Policy Transmission investigates
which firm characteristics make firm investments more sensitive to
monetary policy and highlights the potential role of investment
frictions for a stronger transmission to young firms.
Monetary Policy Transmission in the Presence of Investment Frictions
analyzes investment dynamics and responses to interest rate changes in
a model with capital adjustment costs.
Heterogeneity in Corporate Debt Structures and the Transmission of
Monetary Policy studies how differences in the aggregate structure of
corporate debt - bank loans and corporate bonds - affect the
transmission of monetary policy.
Corporate Leverage and Monetary Policy Transmission examines how
the macroeconomic transmission of monetary policy changes when
there are unexpected shifts in aggregate corporate leverage.
