The case for business ethics was recently made very clear to me when I co-chaired at the New York State Bar Association International Section’s Seasonal Meeting in Guatemala, particularly as it relates to hidden ethics risks in M&A transactions.  I wrote a piece for the Law360 site as part of their "Expert Analysis" explaining these risks.  It's a case study about A.P Moller-Maersk who purchased a port in Guatemala in 2016 just before it became embroiled in a corruption scandal, eventually adding another $43M to their acquisition costs to get a new, clean permit.
