UN criticises developed countries for reneging on promises on sexual health

Promises and Endogenous Reneging Costs∗

We present a novel theoretical mechanism that explains the capacity for non-enforceable communication about future actions to improve efficiency. We explore a two-player partnership game where, before choosing a level of effort to exert on a joint project, each player makes a cheap talk promise to their partner about their own future effort. We allow agents to incur a psychological cost of rene...

On Learning, Lower Bounds and (un)Keeping Promises

We extend the line of research initiated by Fortnow and Klivans [FK09] that studies the relationship between efficient learning algorithms and circuit lower bounds. In [FK09], it was shown that if a Boolean circuit class C has an efficient deterministic exact learning algorithm, (i.e. an algorithm that uses membership and equivalence queries) then EXP 6⊆ P/poly[C] . Recently, in [KKO13] EXP was...
