Equilibrium Storage in a Markov Economy
No full textWe model an economy that alternates randomly between abundance and scarcity episodes. We develop an original method to characterize in detail the structure of the Markovian competitive equilibrium. Accumulation and drainage of stocks are the main focuses. Economically appealing comparative statics results are proved. We also characterize stationary distribution of states. We extend the model to discuss price stabilization policies, injection and release costs, and limited storage capacity. Overall, the analysis delineates the notion of “flexible economy.”Price stabilization; strategic stocks; supply risk

The trigger system of the ARGO-YBJ experiment
No full textAstrophysical radiation with ground-based observatory at YangBaJing (ARGO-YBJ) is a ground-based cosmic ray detector presently under construction at the Yangbajing High Altitude Cosmic Ray Laboratory (4300 m a.s.l.), Lhasa, Tibet. The apparatus has been designed to detect air showers with an energy threshold of a few hundred GeV and it has a total active area of 6400 m 2. The full-coverage central carpet of 5772 m2 is equipped with an array of resistive plate counters. This array is surrounded by a partially instrumented guard ring to improve the reconstruction of showers with the core falling outside the carpet. The ARGO trigger logic implements simple yet robust algorithms, based on the timing distribution of the hits and their multiplicity on the central carpet. In this paper, we describe the hardware architecture and the main features of the trigger system
Donato Creti, La Vierge de l’Apocalypse entre saint Vincent Ferrier et saint Antoine de Padoue
No full textIl dipinto viene reso noto in questa sede. E' un'opera di alta qualità per invenzione e resa grafica e pittorica; testimonianza non solo della eleganza rara della maniera del Creti, che si rivela versato nella pittura profana come universalmente riconosciuto ma anche eccellente nella raffigurazione del sacro. La piccola pala è composta secondo un equilibrio scandito da una misura quasi matematica nella proporzione delle figure poste entro i termini di un triangolo che evoca la Trinità e caratterizzate da gestualità composta e equilibrata, memore degli amati modelli reniani, ulteriore dimostrazione del rigoroso e perseguito intellettualismo dell'autore

No full textA surplus and welfare analysis of asymmetric regulation
No full textSome European regulators have decided to force competition in their nationalmarkets. They have decided to go beyond the second directive and apply asymmetric regulation. Gas release programs and market shares constraints are the two asymmetric decisions imposed to incumbents. When a regulator imposes a gas release program to an incumbent, this operator is compelled to release quantities of its long term contracts to its competitor. In this paper, we will focus on gas release and its impact on welfare, consumer surplus and on the level of released quantities set by regulators. The aim of a gas release program is to give access to natural gas to competitors. They become actives on the market and are in competition with the incumbent. These programs are time limited. They only help competitors in expecting the development of hubs or new investments in importation infrastructures. If competitors want to stay active after the program, they may find others supply sources to increase security of supply. The gas release can induce Raising Rival's Costs or "Self-Sabotage" strategies. We use a Cournot model with capacity constraints to answer two questions. First, we will study the impact of these strategies on consumer surplus and welfare. We will show that there are no impact on consumer surplus but the welfare decreases. The gas release program introduces a transfer of profit between competitor and incumbent, reduces welfare because of the increase in costs of supply, but has no impact on total consumed quantities. Then, we will suppose that the regulator is setting released quantities maximising welfare. Gas release price is often based on costs plus a bid or a fixed premium. Quantities are set with a less obvious process. We will demonstrate that the regulator must set released quantities :- that would not be so high if incumbent's supplies are small to avoid Self- Sabotage or RRC strategies ;- as a function of incumbent's supplies if they are in intermediate values to avoid strategies seen above and to optimise quantities sold on the market ;- at a sufficient level to let the two operators playing their Cournot best reply function. Finally, we will conclude that the regulator can avoid RRC or Self-Sabotage strategies in maximising the welfare when it decides gas released quantities. Gathering from empirical studies, these quantities should not be so high in order to let a significant difference between the capacities of both competitor and incumbent to avoid collusive behaviours.Energy market ; Gas release ; Regulation ; Optimal released quantities ; Efficiency ; Welfare
