In countries with unstable conditions, negotiations regarding construction work takes place under conditions of great uncertainty with both sides, the purchaser and the investor, trying to minimize the difficulties. This paper gives an insight of how matters relating to costing are looked at by professionals when faced with such conditions. 相似文献
In view of the currently observed energy prices, recent price scenarios, which have been very moderate until 2004, also tend to favor high future energy prices. Having a large impact on energy-economic scenarios, we incorporate uncertain energy prices into an energy systems model by including a stochastic risk function. Energy systems models are frequently used to aid scenario analysis in energy-related studies. The impact of uncertain energy prices on the supply structures and the interaction with measures in the demand sectors is the focus of the present paper.
For the illustration of the methodological approach, scenarios for four EU countries are presented. Including the stochastic risk function, elements of high energy price scenarios can be found in scenarios with a moderate future development of energy prices. In contrast to scenarios with stochastic investment costs for a limited number of technologies, the inclusion of stochastic energy prices directly affects all parts of the energy system. Robust elements of hedging strategies include increasing utilization of domestic energy carriers, the use of CHP and district heat and the application of additional energy-saving measures in the end-use sectors. Region-specific technology portfolios, i.e., different hedging options, can cause growing energy exchange between the regions in comparison with the deterministic case. 相似文献
This paper investigates the existence of a long-term relationship between oil prices and GDP in 12 European countries. To account for the fact that economic activity responds asymmetrically to oil price shocks, we propose an approach based on asymmetric cointegration. Our results show that, while standard cointegration is rejected, there is evidence for asymmetric cointegration between oil prices and GDP in the majority of the considered European countries. 相似文献
This paper examines the stagnation of the Dutch housing production in the late 1990s and identifies possibilities for raising production in the near future. Dutch housing production is placed in a theoretical and historical context. Special attention is devoted to the relationship between housing production, price developments, the economic cycle and urbanization policy. These form the basis for an explanation of the stagnation of Dutch housing production. In addition, it identifies a number of obstructive and disruptive influences in play. Because these are partly steered by government policy, the government needs to re-think its role in the housing (construction) market. 相似文献
In this study, the recent persistent growth of regional house price pattern in Sweden is explained by the fundamental variables and the regional distributive perspective on household income and wealth are indicated to be important to understand the different level and development of regional housing market. We also discuss the long running relationship between house prices and migration flows and highlight its critical role on house price analyses. 相似文献
The literature on housing markets suggests that house prices in almost all western economies can be explained by short-run
demand-oriented variables and a long-run term. The basic principles of the theory are that the short-run fluctuations, which
are based on recent price developments (shocks), occur due to market imperfection, while over the long term, causality with
such fundamentals as income will recover. Nonetheless, many of the interesting questions in housing economics concern adjustments
toward equilibrium. This paper seeks to identify a long-run equilibrium between interest payments and household income (interest-to-income
ratio) instead of between house prices and income (price-to-income ratio).
