In this paper we describe the modelling of producer/consumer constraints with the CHIP system. Producer/consumer constraints arise in scheduling problems with consumable resources like raw materials or money, in particular for batch based processing. The constraint assures that at each time point enough consumable resources are available. The modelling with CHIP uses the cumulative constraint t...

The EU Farm to Fork (F2F) strategy includes a number of policy objectives that have implications for agricultural production in the and beyond. This contribution discusses possible from an economic perspective. We draw on assessments by other authors discuss their wider considering only partially quantified benefits costs. Overall, indicate decline quantitative terms. F2F negatively affects agg...

With the development of restructured power systems and increase of prices in some hours of day and increase fuel price, demand response programs were noticed more by customers. demand response consists of a series of activities that governments or utilities design to change the amount or time of electric energy consumption, to achieve better social welfare or some times for maximizing the benef...

Reference price systems for prescription drugs constitute widely adopted cost containment tools. Under these regimes, patients co-pay a fraction of the difference between a drug's pharmacy retail price and a reference price that is set by the government. Reference prices are either externally (based on drug prices in other countries) or internally (based on domestic drug prices) determined. We ...

VARIAN [1985] AND SCHWARTZ [1990] PROVED THAT, very generally, monopolistic third-degree price discrimination decreases aggregate welfare if total output falls (a conjecture which dates back to the work of A. C. Pigou, [1920]). In particular, these authors adopted a representative consumer approach (by assuming quasi-linear preferences) and used revealed-preference arguments. En passant, their ...

Resource-constrained project scheduling problems are one of the most studied scheduling problem, and constraint programming with nogood learning provides the state-of-the-art solving technology for them, at least when the aim is minimizing makespan. In this paper we examine the closely related problem of scheduling producers and consumers of discrete resources and reservoirs. Producer/consumer ...

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 ...
