The news hit the wires this morning: Jason Collins, the former NBA centre who shattered a significant barrier in professional sports, has died at the age of 47. For the City of London, a place that measures legacy in terms of impact and influence, Collins's career represents a fascinating case study in the economics of courage. Coming out as gay in 2013, an era when the locker room was still a bastion of outdated masculinity, Collins essentially traded his marketability for authenticity.

The market, however, proved efficient. His jersey sales spiked, his endorsement deals diversified, and his net worth, while not stratospheric, reflected a premium on integrity. This is the bottom line: Collins showed that diversity, when genuine, is not a cost but an asset.

The UK, ever keen to celebrate pioneers, will recall his contribution not just to basketball but to the broader portfolio of human rights. Collins leaves behind a legacy that, like a well-diversified portfolio, pays dividends in social progress.
