A new study sponsored by NTT claims that firms practicing social sustainability policies are more profitable than firms which do not do so. The problem, as always, is that correlation is not causation. We cannot conclusively prove that social sustainability policies produce better financial outcomes. We can only correlate financial outcomes with the degree of spending on such programs.
In other words, the relationship between ESG and firm profits is unclear.
That tends to be the case for other correlations between firm profits and employee happiness, for example.
It often is claimed that such policies promoting diversity and inclusion may improve employee morale and productivity. The link between employee happiness and productivity is itself unclear.
We find the same pattern in studies examining the relationship between economic growth and broadband deployment. Such studies have found a positive, negative or no relationship between broadband and economic growth.
The point is that complex outcomes are hard to definitively pin to any single input. Where there is correlation, there might not be causation. And where there is correlation, such correlation can be positive, neutral or negative.
