We propose an overlapping-generations model in which established researchers evaluate the research of new researchers. All researchers are differentially endowed with equally desirable research characteristics and belong to two groups, M or F, which have identical ex-ante productivity...

We propose an overlapping-generation model wherein researchers belong to two groups, M or F , and established researchers evaluate new researchers. Group imbalance obtains even with group-neutral evaluations and identical productivity distributions. Evaluators’ self-image bias and mild...
