Última Economic Competition and Evolution: Are there Lessons from Ecology? AgEcon Tisdell, Clement A.. After discussing generally models in ecology and economics that combine competition, optimization and evolution, this article concentrates on models of intraspecific competition. It demonstrates the importance of diversity/inequalities within populations of species and other environments for the sustainability of their populations, given the occurrence of environmental change. This is demonstrated both for scramble (open-access) and contest competition. Implications are drawn for human populations and for industrial organization. The possibility is raised that within industry competition may not always exist between firms in all stages of the development of a new industry. Policy implications are considered. For example, it is argued that policies...

The typical model of retail pricing for produce products assumes retailers set price equal to the farm price plus a certain markup. However, observations from scanner data indicate a large degree of price dispersion in the grocery retailing market. In addition to markup pricing behavior, we document three alternative leading pricing patterns: fixed (constant) pricing, periodic sale, and high-low pricing. Retail price variations under these alternative pricing regimes in general have little correlation with the farm price. How do retailers’ alternative pricing behaviors affect farmers’ welfare? Using markup pricing as the baseline case, we parameterize the model to reflect a prototypical fresh produce market and carry out a series of simulations under...

Ano: 2009 URL: http://purl.umn.edu/51720 Risk Mitigating Strategies in the Food Supply Chain AgEcon Agiwal, Swati; Mohtadi, Hamid. Food safety events in the recent past have generated significant media attention and resulted in increased concerns over the food on the plate. A recent study (Degeneffe et al., 2007) on consumer perceptions of bio-terrorism and food safety risks shows increasing concern over food safety and corresponding decreasing confidence in security of the U.S. food supply. While there are some mandated safety and security practices for the firms in the food supply chain the economic incentives for the firms to actively address food safety throughout the supply chain are less clear. Security practices often require significant investments in both within the firm and across the supply chain but do not show tangible returns. Also, higher investments in securing the...
