This paper derives the conditions under which fitness-reducing alleles can survive in a long-run stationary equilibrium for a trading population, extending the results in Saint-Paul (2002) for arbitrary systems of sexual reproduction.

We study effects of a firm's attempt to optimize an existing incentive scheme to increase sales growth for direct store delivery workers. Before optimization workers reported Ratchet Effects that lowered productivity. The altered incentive plan offered higher compensation for increased sales...
