This isn't entirely a tax justice subject - it's much more generic than that - but if you can see past the stilted IMF-speak it's interesting anyway. This is another IMF working paper, entitled "A Fistful of Dollars: Lobbying and the Financial Crisis
" whose introduction notes:
"Using detailed information on lobbying and mortgage lending activities, we find that lenders lobbying more on issues related to mortgage lending
Ex-post, delinquency rates are higher in areas where lobbyist' (sic) lending grew faster and they experienced negative abnormal stock returns during key crisis events. The findings are robust to (i) falsification tests using lobbying on issues unrelated to mortgage lending,
- had higher loan-to-income ratios,
- securitized more intensively, and
- had faster growing portfolios.
(ii) a difference-in-difference approach based on state-level laws, and
(iii) instrumental variables strategies.
These results show that lobbying lenders engage in riskier lending."
