Green bonds in the European bond market (joint work with Benedikt Franke and Pia Stoczek): Among sustainable financing solutions, green bonds serve as an important channel to fund environmentally friendly projects. A major question is why firms issue green bonds and which role transparency and certification requirements play. This study investigates the role of firm transparency, in interaction with other sustainability regulation, on potential premium from green bonds. Issuance of green bonds is deemed as firms’ commitment to future sustainability efforts. Transparency requirements play a major role in whether such commitments are credible or not, which potentially affects political decisions.
