Abstract An artist’s death constitutes a negative shock to his future production; death permanently decreases the artist’s float. We use this shock to test predictions of speculative trading models with short-selling constraints. As predicted in our model, we find that an artist’s premature death leads to a permanent increase in prices and turnover; this effect being larger for more famous artists. We document that premature death increases prices (by 54.7%) and secondary market volume (by 63.2%).

The paper is focused on analysis of return on speculative operations with futures contracts from the view of participators not undertaking and undertaking the currency risk. The currency risk is determined by unexpected change of relevant exchange rate (currency denomination of futures contracts / domestic currency of participator). The paper analyses the basic factors influencing the profitability of these operations such as relative change of futures contract value, leverage incidence and relative change of relevant exchange rate. The paper is focused on futures contracts of the world most important agricultural commodities. The conclusion of the paper for participators not undertaking the currency risk is following: The relative change of futures contract is main factor for the calculation of return on speculative operation. This change is multiplied by leverage incidence finally. The conclusion of the paper for participators undertaking the currency risk is following: The relative change of relevant exchange rate is not usually relevant for the calculation of return on speculative operation. Main factor is the relative change of futures contract because this change is multiplied by leverage incidence finally but the relative change of relevant exchange rate isn’t.Neverthless the conclusions of this paper are not valid only for futures contracts of agricultural commodities but generally also for other commodity futures contracts and futures contracts where underlying assets are not commodities but for example financial assets.

Renewable energy sources produce less environmental impact and have little marginal cost. Thus, because of these characteristics, it is desirable to disseminate it for the purpose of economic efficiency. Because of the uncertainty in the supply of renewable energy and the special feature of electricity as a good, such as merit order curve, introducing forward markets is an essential factor in a liberalized market. In European countries, which have already established several mechanisms for managing liquidity including markets with several timelines, the market liquidity invites the investor to perform some speculative action. We present a simple electric power market model to analyze the speculative actions of electricity suppliers and the price effect of such actions. Moreover, we found that the speculative action improves the inelasticity of the demand in electricity market.

Historically, LNG has been sold through long-term contracts with limited flexibility in volume and price. LNG trade patterns have evolved significantly, adding to increased sales of multiple cargoes on the spot market, brokered trades and speculative trading positions being taken up by non-traditional players. Buyers in the Asia-Pacific region are keen to secure supply for local markets, while Australian producers, particularly subsidiaries of foreign headquartered groups, are under pressure to sell at competitive prices. From a transfer pricing perspective, the Australian Taxation Office (ATO) has placed increased scrutiny on the commerciality of arrangements, arm’s length outcomes and profit allocations between Australian taxpayers and their international related parties (e.g. marketing and trading hubs). This extended abstract covers: factors that could impact on the selection of a price index and the slope or gradient to be applied in pricing formulae; blended pricing based on an average of different indices, and why pooling and trading may make commercial sense, although revenue authorities may not look favourably upon it; the importance of the contractual terms, the market situation and the other commercial contract conditions on the pricing of related-party LNG sales; and, the value in potentially seeking an advanced pricing agreement in a related party LNG pricing context, given the significance of the transactions. Given the practical and commercial challenges facing the industry and with several projects commencing production in the relatively near future, this is very topical. The authors use case studies to illustrate the key concepts.
