Only the top 10% of US earners have seen their incomes grow faster than productivity since 1966. Part of the top-earner income growth is driven by market forces (superstar economics); the only feasible pro-equality policy here is more progressive taxation. For top corporate executives, however, non-market forces (CEO-Board complicity in pay setting) are important, so other policies are warranted. Increased disclosure and improved corporate governance would distribute economic gains more evenly across society and boost firms’ value.
