a r t i c l e i n f o In competitive product markets, repeated interaction among producers with similar economic characteristics would be expected to result in convergence of their behaviors. If convergence does not occur, it raises fundamental questions related to the sustainability of heterogeneous competitive strategies. This paper examines the prices submitted to the British wholesale elect...

In a competitive electricity market with substantial involvement of renewable electricity, maximizing profits by optimizing bidding strategies is crucial to different power producers including conventional power plants and renewable ones. This paper proposes a game-theoretic bidding optimization method based on bi-level programming, where power producers are at the upper level and utility compa...

abstract efficacy of encouraging and punishing policies of government in different markets is related to market power. study of market behavior is also important for efficient structuring of tools such as commodity exchanges and cooperatives. in this study, market power structure of pistachio domestic market in iran was investigated. sample was 343 pistachio producers and 252 pistachio traders ...

Nutrient limitation determines the primary production and species composition of many ecosystems. Here we apply an adaptive dynamics approach to investigate evolution of the ecological stoichiometry of primary producers and its implications for plant-herbivore interactions. The model predicts a trade-off between the competitive ability and grazing susceptibility of primary producers, driven by ...

This paper addresses the widely debated issue of comparing the relative efficiency of two doubleauction mechanisms for power exchanges. An agent-based modeling approach is adopted to simulate a double-auction power exchange. Two standard pricing rules are considered and compared: “discriminatory” and “uniform”. Computational experiments, characterized by different inelastic demand level, reprod...

The United States is one of few countries where the majority of bell peppers (Capsicum annuum L.) produced are green colored and grown on raised beds with mulch and drip irrigation. Outside the U.S., most peppers are grown in greenhouses and harvested as mature, colored peppers that receive a premium value at market. Florida bell pepper producers are in direct competition with Mexico, Israel, a...

in the present study, 110 fungal strains of persian type culture collection (ptcc) including some selected strains isolated in various screening projects were tested for their potentiality to produce lovastatin, a competitive inhibitor of 3-hydroxy-3-methylglutaryl-coa reductase (hmg-coa reduc-tase), the rate-limiting enzyme of cholesterol biosynthesis. the fungal strains were cultivated in a t...
