Accountability is linked to replaceability.
When you’re negotiating with other people, ultimately if someone else is making a decision about how to compensate you, that decision will be based on how replaceable you are. If you have high accountability, that makes you less replaceable.

Accountability becomes equity.
Employees earn salaries, but equity holders earn a portion of the upside (profits). People with no accountability earn the lowest wages because they’re the most replaceable. People with lots of accountability will earn a salary, but will also earn equity which gives them a much higher upside when the company/project does well.

Airline Pilots & Risk. 
A great example of accountability in a work context are airline pilots. The airplane’s captain has accountability of the plane and the flight. He likely gets paid much more than the flight attendants because he’s responsible for the flight.

The risk becomes, if you’re in charge and something bad happens, your name get’s linked to it. But in the context of business it’s rarely a matter of life-and-death.  Your failing as an app developer doesn’t kill a plane full of people.  So don’t be worried about taking risks and being accountable for them.
