Persuasion with correlation neglect
écrit avec Ines Moreno de Barreda and Ronny Razin
We consider an information design problem in which a sender tries
to persuade a receiver that has correlation neglect, i.e., fails to
understand that signals might be correlated. We show
that the sender can change the expected posterior of the receiver in any
direction. When the number of signals the sender can send is large, she can
approach her first best utility. We characterize for which environments full correlation is the optimal solution;
in these cases we can use a modified problem and standard concavification techniques. We show that full correlation is optimal in the familiar case of binary utilities but also more
generally when utilities are super-modular and when the number of signals is large. However, in some environments full correlation is not optimal and in those cases the optimal solution involves negative correlation

Demographic Change and Climate Change
The paper uses a continuous-time overlapping-generations model with endogenous growth and pollution accumulation over time to study the link between longevity and global warming. It is seen that increasing longevity accelerates climate change in a business-as-usual scenario without climate policy. If a binding emission target is set exogenously and implemented via a cap-and-trade system, the price of emission permits is increasing in longevity. Longevity has no effect on the optimal solution of the climate problem if perfect intergenerational transfers are feasible. If these transfers are absent, the impact of longevity is ambiguous.
