Asymmetric Competition Among Distant Taxa

Evolutionary branching under asymmetric competition.

I investigate the evolution of a continuous trait, such as body size or arms level, which affects the outcome of competitive contests such that the contestant with the larger trait value has a higher probability of winning. I show that a polymorphism of distinctly different strategies can evolve in an initially monomorphic population even if mutations have only small phenotypic effect. In a sim...

Asymmetric Consumer Learning and Inventory Competition

We develop a model of consumer learning and choice behavior in response to uncertain service at the marketplace. Learning could be asymmetric, i.e., consumers may associate different weights with positive and negative experiences. Under this consumer model, we characterize the steady-state distribution of demand for retailers given that each retailer holds constant in-stock service level. We th...

Asymmetric Competition in B2B Spot Markets

W model strategic behavior of two types of suppliers in B2B spot markets: a supplier that has forward contracts and uses the spot market only for inventory liquidation, and a supplier that uses the spot market as its sole selling channel. We find that when the spot market demand is small, the supplier that has forward contracts has a higher incentive to invest in expanding the spot market. When...
