Market-wide, stock market specific, and real estate market specific risk – what kind of risk and to which extent drives the returns of listed real estate? Based on a structural asset pricing model calibrated to the empirical data in the U.S., we show that at least two thirds of the risk premium of listed real estate are driven by the same factors as direct real estate. Our results shed new light on the risk-characteristics of listed real estate returns and are of high interest for academics, regulators, and portfolio managers alike.  相似文献

The stabilization of budget deficit and budget debt ratios by fiscal retrenchment in order to fulfill the Maastricht criteria for the EMU is of central focus in most EU countries. At the same time the national policy dimension of acute environmental problems such as global warming has receded in the public eye. The environmental dimension nonetheless remains urgent, and a re-evaluation of the prospects of CO2-policy is needed against the background of fiscal retrenchment required by supranational obligations. We shall do this for the small, open, Austrian economy by constructing a dynamic multi-cohort CGE model enabling us to assess quantitatively the lifetime welfare impacts on the cohorts affected by three different options for using CO2-permit revenues. The distribution of welfare costs of (Toronto-) CO2-policy across cohorts significantly differs with use. This is explained by income, inheritance and price effects.  相似文献

The business and information systems engineering (BISE) discipline, dominating in the German-speaking countries, where it is called“Wirtschaftsinformatik”, is currently undergoing a phase of increasing internationalization and the U.S.-based Information Systems (IS) discipline is often considered an ideal. Studies show that BISE has often dealt with fads in the past – for IS there are no findings reporting on the diffusion of fads. The objective of the paper is to close this research gap. The authors conducted a literature analysis to investigate the development of topics and terms in BISE and IS from 1994 to 2007. Titles, abstracts and keywords of 2,564 articles in three BISE journals and 5,647 articles in five IS journals were analyzed. The results show that BISE is topically more diverse and concrete than IS. In addition, the rate of fads is higher in BISE than IS. Being engaged in fads is not necessarily negative – rather, it may considerably contribute to the relevance of research. However, it has to be considered that an overly intense orientation on fads may negatively influence a cumulative research progress. Hence, the authors conclude that for BISE and IS, which both have a theoretical and pragmatic mission, a balanced ratio of short- and long-term topics seems appropriate.  相似文献

The transition to an implicitly solar-basedenergy system can make use of various specificbiomass energy systems. This paper provideseconomic and environmental indicators forevaluating alternative options.The paper proceeds in three empirical steps.First, an expert survey supplies the primarybiomass potentials available for non-food usein Austria and their respective costs. Second,an inquiry into investment, operating andfinancing costs of 30 different biomass energyuse systems allows a standardized comparisonamong them and their relationship to fossilreference technologies. Third, a computablegeneral equilibrium model of the Austrianeconomy is employed to quantify the impacts offostering the use of distinct biomass energytechnologies.The results allow us to distinguish betweenthose technologies that tend to lead to anincrease in both GDP and employment (e.g.,combined heat and power production from sewagesludge biogas), to an increase only inemployment, while GDP tends to diminish (e.g.,district heating based on agricultural pellets)or to a decline in both (e.g., co-firing basedon wood-chips, bark or industrial pellets).Individual technologies could account for up toone third of Austrias Kyoto obligation, whilecombinations of technologies, triggered by acombined CO2 tax and biomass energysubsidy for example, could almost fully lead toAustrian Kyoto-compliance.  相似文献

Car-sharing organizations (CSO) have recently spread throughout central European cities and currently have 20000 members. They lower individual fixed costs of car availability change the incentive structure of private vehicle use by transforming nearly all costs into variable costs. A survey of all current Austrian CSO members is used to identify the characteristics significant of members. A procedure is proposed to quantify urban local market segment potentials and is applied to two residential areas. The net impact of CSOs depends on how the new incentive structure changes mobility behavior. A controlled experiment of voluntary new members was carried out to compare pre-membership and membership trip structure and modal split. Results indicate a substantial reduction of aggregate private vehicle mileage. While the share of trips by car is constant, changes in trip length are observed, with there being different changes for households which previously owned a car and those which did not. Combining behavior impact with market segment size results in the quantification of emission reduction and car ownership reduction (land use demand) due to car-sharing, which is a decentralized demand-side transport policy.  相似文献

Sustainable development at both the national and the global level is increasingly acknowledged to be dependent upon the international trade system. The WTO Agreements and the continuing discussion in the WTO Committee on Trade and Environment are therefore examined here in the light of principles put forward by the International Institute for Sustainable Development. The current shortcomings in the WTO are analysed and some possible cornerstones for future WTO development indicated.  相似文献

The attitudes and policy orientations of the West German unions to the development and utilisation of new technologies have changed substantially over the past three decades. Contemporary union policies are more critical and more politically oriented: the changes which they seek, to more successfully influence technological developments, have potentially crucial significance for the future character and stability of the West German industrial relations system.  相似文献
