Dynamics and equilibria of ecological predator–prey networks as nature’s supply chains

Abstract: In this paper, we develop a dynamic network model of ecological food webs and prove that the set of stationary points of the projected dynamical system coincides with the set of solutions of a variational inequality governing the equilibrium of predator–prey networks. We also establish the equivalence between the ecological models and supply chain network equilibrium models and highlight the connections to spatial price equilibrium problems. We propose an algorithmic scheme, provide convergence results, and apply it to a food web drawn from a fisheries application. This paper is a contribution to the interdisciplinary supply chain network literature.

Credit rationing and black-owned firms: is there evidence of discrimination?

Abstract: This article uses data from the 2003 Survey of Small Business Finances to determine if banks ration credit more severely to black-owned firms. Our results reveal this is the case. Using the Heckman two-step procedure, we determined that black- and white-owned firms have a comparable demand for credit as measured by their actual use of lines of credit. Controlling for firm and owner characteristics, however, black-owned firms had lower line of credit limits suggesting constraints in supply. Further, our findings suggest the supply of credit to black-owned firms is even more severely constrained than other minority-owned firms. These findings highlight the possibility of discrimination against black-owned firms in the form of credit rationing.
