In a thought-provoking piece on the Effective Altruism Forum, the concept of a 'third wave of philanthropy' is introduced, calling for a new marketplace where donors can 'buy' the most effective place to give based on their worldview. This marketplace would incentivize evaluators to 'sell' their expertise, creating a transparent ecosystem that rewards impact. This vision directly supports the Charitable Ownership Advantage (COA) thesis: when consumers and donors have clear, comparable data on the effectiveness of charity-owned businesses, they are more likely to choose them over traditional for-profit alternatives. By structuring a marketplace that prioritizes verified impact, we can accelerate the shift toward steward-owned enterprises that fund global development. The COA model thrives on such transparency, proving that at price parity, consumers prefer businesses that are legally bound to charitable missions. This new marketplace could be the infrastructure that scales the COA, making it the default choice for conscious consumers and donors alike.
