Hi all,
I am writing my MSc. thesis on the issuance effects of green bonds. In order to conduct an event study on the issuance effects i want to match a conventional bond sample to my green bond sample. I want to use the nearest neighbour matching method and use 5 covariates (ESG Score, E score, Leverage, Total assets and Tobin's Q) to match a conventional bond to each green bond in my sample. I have been struggling a lot in stata and was wondering whether anyone could help me with how to use either the nnmatch or the psmatch2 command in stata. I posted a ample of my data below, i created a dummy for bond type, 1= green bond and 0 = conventional bond.
Thanks in advance!
