producers and consumers’ price behavior were analyzed in chicken meat market in fars province. monthly average producers and consumers prices from june 1997 to july 2008 were taken into account. changes in the producer and consumer prices indicated that the prices follow an increasing trend with much fluctuations. marketing margin has an increasing trend of violent fluctuations. the result of g...

Filming or videotaping a work of art is traditionally done in either the gallery or studio setting. In either case, the work is taken off view and methodically surrounded by camera and lighting equipment. This process is time consuming, expensive and places the work at risk of being damaged by light, heat and/or toppling equipment. The tremendous investment and risk involved in this process req...

We empirically analyze convergence of European producer and consumer prices for diesel fuel and investigate the role of excise taxation. By comparing the speed of convergence of prices and taxes we find a surprisingly fast speed of convergence for consumer prices. While this can in part be explained by fuel tourism, the main driving force is producer price dynamics. Tax convergence contributes ...

The advent of nearly ubiquitous information infrastructures has led many to predict that one effect of electronic markets will be the bypassing of intermediaries in electronic markets. The ability of electronic networks to reduce transaction costs is the theoretical cause of this supposed trend. We suggest that, on the contrary, not only is it likely that widely available information infrastruc...

In the economic model that underlies the WTO the only group that can be expected to ask for protection is producers in importing countries. The existing multilateral trade architecture reflects that assumption. Much of the recent criticism of the multilateral trade regime has arisen as a result of new groups explicitly asking domestic politicians for protection. As these groups were not expecte...

The article presents a costing system for a fiberboard producer. Resource consumption costing was chosen as the underlying cost accounting methodology. Technological links between the consumption of resources and final cost objects have been reflected in designing the costing system. Allocation bases derived from the features of the production flow for allocating resources costs to cost objects...

This paper presents a framework for discussing issues of ownership in connection to virtual worlds. We explore how divergent interests in virtual property can be mediated by applying a constructivist perspective to the concept ownership. The simple solutions offered today entail that a contract between the game producer and the gamer gives the game developer exclusive rights to all virtual prop...

Nutrient availability and herbivory control the biomass of primary producer communities to varying degrees across ecosystems. Ecological theory, individual experiments in many different systems, and system-specific quantitative reviews have suggested that (i) bottom-up control is pervasive but top-down control is more influential in aquatic habitats relative to terrestrial systems and (ii) bott...

Heat-stress remains a costly issue for animal production, especially for poultry as they lack sweat glands, and alleviating heat-stress is necessary for ensuring animal production in hot environment. A high γ-aminobutyric acid (GABA)-producer Lactobacillus strain was used to investigate the effect of dietary GABA-producer on laying performance and egg quality in heat-stressed Hy-line brown hens...

Demand response programs in retail electricity markets are very popular. However, despite their success reducing average consumption, the random responsiveness of consumers to price events makes efficiency questionable achieve flexibility needed for electric systems with a large share renewable energy. This paper aims at designing demand contracts that allow act on both consumption and its vari...
