We develop a structural risk‐neutral model for energy market modifying along several directions the approach introduced in Aïd et al. In particular, a scarcity function is introduced to allow important deviations of the spot price from the marginal fuel price, producing price spikes. We focus on pricing and hedging electricity derivatives. The hedging instruments are forward contracts on fuels and electricity. The presence of production capacities and electricity demand makes such a market incomplete. We follow a local risk minimization approach to price and hedge energy derivatives. Despite the richness of information included in the spot model, we obtain closed‐form formulae for futures prices and semiexplicit formulae for spread options and European options on electricity forward contracts. An analysis of the electricity price risk premium is provided showing the contribution of demand and capacity to the futures prices. We show that when far from delivery, electricity futures behave like a basket of futures on fuels. 相似文献

加利福尼亚州是美国经济最发达的州,相当于世界第八大经济体,然而近年来加州政府却挣扎在濒临破产的边缘。长期的入不敷出是导致加州财政危机的直接原因,但背后却隐藏着美国联邦财政体制、税制结构、福利模式、两党政治博弈、三权分立的行政效率等深层次的原因。加州财政危机是美国政治、经济、社会的体制矛盾的集中反映。近年我国地方政府债务规模迅速增大,高速的经济增长掩盖了大量风险。加州财政危机对治理我国地方债务风险具有重要的借鉴意义。 相似文献

Companies often begin their search for great ideas either by encouraging wild, outside-the-box thinking or by conducting quantitative analysis of existing market and financial data and customer opinions. Those approaches can produce middling ideas at best, say Coyne, founder of an executive-counseling firm in Atlanta, and Clifford and Dye, strategy experts at McKinsey. The problem with the first method is that few people are very good at unstructured, abstract brainstorming. The problems with the second are that databases are usually compiled to describe current--not future--offerings, and customers rarely can tell you whether they need or want a product if they've never seen it. The secret to getting your organization to regularly generate lots of good ideas, and occasionally some great ones, is deceptively simple: First, create new boxes for people to think within so that they don't get lost in the cosmos and they have a basis for offering ideas and knowing whether they're making progress in the brainstorming session. Second, redesign ideation processes to remove obstacles that interfere with the flow of ideas--such as most people's aversion to speaking in groups larger than ten. This article offers a tested approach that poses concrete questions. For example, what do Rollerblades, H?agen-Dazs ice cream, and Spider-Man movies have in common? The answer: Each is something that adults loved as children and that was reproduced in an expensive form for grown-ups. Asking brainstorming participants to ponder how their childhood passions could be recast as adult offerings might generate some fabulous ideas for new products or services. 相似文献

In most OECD countries, the wage gap between men and women has narrowed during the past two decades. Developments of the last
20 years, e.g., increased labour market attachment of women or the introduction of equal pay laws, may have reduced the gender
wage gap. We investigate the extent, persistence, and socio-economic determinants of the gender wage gap in Austria, for the
years 1983 and 1997. Using wage decomposition techniques, we find that the average gender wage gap was almost as high in 1997
as it was in 1983. Not accounting for differences, the gender wage gap dropped from 25.5 to 23.3% of men’s wages. Taking observable
differences between men and women into account, we estimate that the mean gender wage gap that cannot be explained, i.e.,
discrimination against women, dropped from 17 to 14% of men’s wages. A decomposition of the gender wage gap over time indicates
that both returns to human capital and less discrimination were responsible for the narrowing of the gender wage gap.
