Forecasting electricity prices in presentday competitive electricity markets is a must for both producers and consumers because both need price estimates to develop their respective market bidding strategies. This paper proposes a transfer function model to predict electricity prices based on both past electricity prices and demands, and discuss the rationale to build it. The importance of elec...

The global wine market is constantly evolving, and producers need to adapt climate change and, in some cases, new marketing trends remain competitive sustain their business. main aim of this article highlight, conceptually, the issues that can affect both consumers producers. To meet objective, we have adopted a conceptual approach. We draw on recent literature review, our understanding industr...

In many instances, nutritionists, feed manufacturers, dairy producers and their advisors need an estimate of what a feed is worth on a nutritional basis to facilitate the formulation of balanced diets and the purchase of appropriate and price competitive feedstuffs. Up until now, all methods used shared common flaws. We derived a maximum likelihood method that uses composition and prices of all...

Harrington et al. [21] introduced a general framework for modeling tacit collusion in which producing firms collectively maximize the Nash bargaining objective function, subject to incentive compatibility constraints. This work extends that collusion model to the setting of a competitive pool-based electricity market operated by an independent system operator. The extension has two features. Fi...

Supply chain formation is the process by which a set of producers within a network determine the subset of these producers able to form a chain to supply goods to one or more consumers at the lowest cost. This problem has been tackled in a number of ways, including auctions, negotiations, and argumentation-based approaches. In this paper we show how this problem can be cast as an optimization o...

The ecological role of interference competition through toxin production is not well understood. In particular, it is unclear under what conditions the benefits of toxic killing outweigh the metabolic costs involved. A killer advantage has been suggested to rely on local competitive interactions where the benefits of killing accrue to the toxin producer preferentially, but this notion has littl...

The paper surveys the price competitiveness of agricultural production in Central and East European Countries (CEECs). It draws together empirical work conducted by the authors and other studies that have estimated domestic resource cost (DRC) ratios for agriculture in various CEECs. The paper identifies that in general CEEC crop production is more internationally competitive than livestock far...

We study a game that models a market in which heterogeneous producers of perfect substitutes make pricing decisions in a first stage, followed by consumers that select a producer that sells at lowest price. As opposed to Cournot or Bertrand competition, producers select prices using a supply function that maps prices to production levels. Solutions of this type of models are normally referred t...
