This paper reviews some multi-unit auction mechanisms that are used in the procurement of electricity. In ordinary auctions bidders compete to buy several units same object from seller, while or reverse suppliers electricity sell a certain number units. Reverse numerous countries and they create competitive market for electricity, instead state-owned monopolies providing at administratively set prices. this we will present most commonly forms markets. Auctions renewable energy sources...

Abstract The aim of this work was to investigate the effect temperature on thickness, surface roughness, visual appearance and morphology electrochemically deposited gold decorative coatings obtained from conventional cyanide electrolyte (AUROCIN DPB) based mercaptotriazole (Au-MT). Heating does not significantly affect thickness ( b ) (at 20 °C = 0.08 μm, at 30 0.07 μm 40 μm) and, for reason, coating processes were carried out room temperature. Temperature increase has a positive...

This paper reviews equilibrium behavior in different auction mechanisms. We will deal with two types of open auctions, English and Dutch, sealed-bid first-price second-price, when there is a single object for sale bidders have private values. show that under certain conditions all four auctions yield the same expected revenue to seller, but once these assumptions are relaxed equivalence does not hold. also study by using standard tools from demand theory. Finally, we analyze collusive...

This paper reviews single object auctions when bidders? values of the are interdependent. We will see how auction forms could be ranked in terms expected revenue signals that bidders have about value affiliated. In discussion follows we deal with reserve prices and entry fees. Furthermore examine conditions to met for English asymmetric allocate efficiently. Finally, common considered all same object.

Abstract The aim of this work was to investigate the effects current density, temperature, pH and concentration ethylhexilsulfonate additive on microhardness electrochemically deposited gold decorative coatings obtained from a conventional cyanide electrolyte complex based mercaptotriazole. Mechanically chemically prepared brass samples were first nickeled acidic electrolyte. Nickel substrate deposit, then two types electrolytes at different densities temperatures. Decorative...

A thermoplastic pultrusion process was examined using commercial fiber roving of PET/E glass, to determine the optimum pulling speed and optimal zonal temperatures. Finite element analysis predicted heat transfer through commingled fibers air in die. The cross-section obtained rods examined, image carried out obtain information about degree impregnation, number voids uniformity distribution. Optimizing temperature field for poly (ethylene terephthalate) is significant importance. has same...

In sequential auctions objects are sold one by in separate auctions. These might be organized as first-price, second-price, or English We will derive equilibrium bidding strategies for these Theoretical models suggest that prices with private values randomly assigned heterogeneous should have no trend. However, empirical research contradicts this result and exhibit a declining increasing trend, which is called price anomaly. present review of results, well different theoretical explanations...

The gradual liberalisation of the EU railway market, which began in early 2000s, has entered its final phase with formal opening national markets for commercial passenger transport. However, level competition established some countries is still not sufficient to increase welfare. Based on previous experience, this phenomenon stems from high barriers entry new operators, such as sunk costs, relatively infrastructure train access charges (TAC) traffic, and between asymmetric participants,...

The subject of this study is the quantitative adhesion a UV-curing composite film based on Bis-GMA (Bisphenol A glycidylmethacrylate) / TEGDMA (triethylene glycol dimethacrylate) as matrix and particles doped with ferrous oxide metal substrate. Two different substrates: silver gold-spattered brass nickel intermediate coating were used in evaluating. Adhesion was measured using micro-identation it compared wetting angle composites to It has been shown that substrates, although similar...

In this paper, we present the problem of matching students to schools by using different mechanisms. This market is specific since public are free and price mechanism cannot be used determine optimal allocation children in schools. Therefore, it necessary use algorithms that mimic enable us core cooperative game. will possible apply game theory problems. review paper based on illustrative examples aiming compare terms incentive compatibility, stability efficiency matching. some problems may...

This paper analyses equilibrium in competitive markets with asymmetrically informed agents. In contrast to Walrasian equilibrium, where price is only an indicator of relative scarcity, the models studied this has two additional roles. It conveys and aggregates private information agents economy. Each agent infers other by studying price. implies that setting have higher cognitive capabilities than The concept used describe these roles called Rational Expectations Equilibrium (REE).

Composite materials based on UV-curing acrylates and various alumina-based reinforcements represent material that is suitable for the use in dentistry, but also other areas. Composites were made using four different types of reinforcement chemically very similar compositions, size morphologies. In order to monitor mechanical properties composite material, samples form discs defined dimensions polymerization under UV light. The subject this study examination Bis-GMA (Bisphenol A glycidyl...

Abstract This paper aims to identify the possible implications of quantity competition in markets with differentiated products on entry deterrence. If capacity commitments characterise this industry, quantities can be expected as choice variable rational players, even presence product differentiation. Different equilibria a static game occur depending degree asymmetry incumbent and entrant, which will crucially affect shape their best response functions. Asymmetry stem from players’...

This paper reviews theoretical models of network competition in telecommunications. We will discuss two alternative approaches. The first approach assumes Hoteling?s horizontal differentiation and the second is based on switching costs. analyse spatial with linear prices continue price discrimination between on-net off-net calls. Price can also be used to deter entry market. deal regulator?s optimal choice access price, which should designed induce new firms. Furthermore, pricing roaming...
