We estimate the equity premium using CDS spreads and structural models of default. Our estimates yield equity premia of 6.50% (U.S.), 5.44% (Europe) and 6.21% (Asia) based on 5year CDS spreads from 2003-2007. Due to some conservative assumptions these estimates are upper limits for the equity premium. Using 3-, 7and 10-year CDS maturities yields similar results and o ers an opportunity to estim...

In it, he famously asked, “What would happen if we could arrange the atoms one by one the way we want them?” It took thirty years for microscopes to b...
