A Search Story About the Peacock's Tail

This paper analyzes a biological model, where (i) males can have an observable and disadvantageous genetic attribute, (ii) females differ in some stochastic endowments, and (iii) screening partners is costly. The main result of the paper is that each male has the disadvantegeous attribute in the unique evolutionary equilibrium, whenever the endowment of the females and the attribute of the males are substitutes in the reproduction function.
