Until now the promotion of renewable energies in Europe has been effected on the basis of different promotion systems of the Member States. Currently the EU-wide harmonisation of the promotion systems, from which yields of efficiency and a higher effectiveness are expected, cannot be enforced due to a discordance concerning the “right” promotion instrument.With the proposal for a directive on the promotion of renewable energies, published at the 23. January in 2008, the European Commission attempts to make a first move towards harmonisation. Besides existing promotion systems it will be possible to transfer Guarantees of Origin for renewable energies between Member States. Since, however, some Member States expect negative effects as a consequence of opening their markets the proposal comprises opportunities to restrict the transfer. The present scope of interpretation within the proposal allows for different options concerning the design of the transfer restrictions. These will be identified, analysed, and subsequently evaluated in this article. Despite of both extreme options, the possibility to entirely opt out of the transfer system and the obligation to completely participate in the transfer system, two further hybrid options are discussed. The latter are characterised by the possibility of Member States to restrict the transfer of Guarantees of Origin to a certain extent through a “system of prior authorisation”. 相似文献

Prior literature indicates that quadratic models and the Black–Karasinski model are very promising for CDS pricing. This paper extends these models and the Black [J. Finance 1995, 50, 1371–1376] model for pricing sovereign CDS’s. For all 10 sovereigns in the sample quadratic models best fit CDS spreads in-sample, and a four factor quadratic model can account for the joint effects on CDS spreads of default risk, default loss risk and liquidity risk with no restriction to factors correlation. Liquidity risk appears to affect sovereign CDS spreads. However, quadratic models tend to over-fit some CDS maturities at the expense of other maturities, while the BK model is particularly immune from this tendency. The Black model seems preferable because its out-of-sample performance in the time series dimension is the best. 相似文献

Theory predicts that market‐timing activities bias Jensen's alpha (JA). However, empirical studies have failed to find consistent evidence of this bias. We tackle this puzzle in a nested model analysis and show that the bias contains an exogenous market component that is unrelated to market‐timing skill. In a comprehensive empirical analysis of US mutual funds, we find that the timing‐induced bias in JA is mainly driven by this market component, which is uncorrelated with measured timing activities. Measures of total performance that allow for timing activities are virtually identical to JA, even if timing activities are present in the evaluated fund. Hence, we conclude that JA is a sufficient measure of total performance. 相似文献

For the insurance industry the moral hazard poses an incalculable risk. Changes in the behaviour of the insuree can lead to higher claims settlements and thus to higher premiums for the insured collective. Asymmetrically allocated information gives the insured individual the possibility to profit from the idea of common protection in a way that impairs insurer and the collective on the whole. Based on the homo oeconomicus model, economic concepts, first and foremost the agency theory of new institutional economics have made attempts to provide solutions for this management problem. However, behavioural economic experiments have demonstrated that the homo oeconomicus model does not fully succeed in describing the realities. As a result, the solutions proposed in these economic concepts have to be rated inadequate.The moral hazard is inherent in the conflicting realm of cooperation and defection, behaviour patterns that have evolved during the history of development of human behaviour. Ultimate behaviour analyses of these patterns do offer the opportunity to understand why humans behave in specific ways based on man's evolutionary origins and sources. Consequently, ultimate behaviour analyses could provide a solid foundation for the development of a framework giving insurers the possibility to exert influence on the insuree's behaviour and thus to assist in successfully impacting the moral hazard. 相似文献

This paper provides an explanation for the increasing reliance on revenue from user charges on excludable public goods. We
develop a model with many identical countries. The government of each country imposes a source-based tax on capital and supplies
an excludable public good to heterogeneous households. Without tax competition, the price on the public good is zero. Tax
competition induces each country to choose a positive price. The reliance on user charges turns out to be increasing in the
intensity of tax competition measured by the number of countries. A coordinated decrease in user charges is shown to raise
welfare in all countries.

We develop a theory’ and empirical test of how the legal system affects the relationship between venture capitalists and entrepreneurs. The theory uses a double moral hazard framework to show how optimal contracts and investor actions depend on the quality of the legal system. The empirical evidence is based on a sample of European venture capital deals. The main results are that with better legal protection, investors give more non-contractible support and demand more downside protection. These predictions are supported by the empirical analysis. Using a new empirical approach of comparing two sets of fixed-effect regressions, we also find that the investor’s legal system is more important than that of the company in determining investor behavior. 相似文献

Using data from the British Household Panel Survey, this study examines the relationship between several outcomes in early adulthood (e.g. education, inactivity, earnings and health) and being born to a teenage mother. Besides standard cross‐sectional multivariate regression estimates, we also present evidence from non‐parametric estimates and from estimates that account for unmeasured family background heterogeneity by comparing siblings born to the same mother who timed their births at different ages. Regardless of the econometric technique, being born to a teenage mother is usually associated with worse outcomes. An important channel of transmission of this adverse effect is childhood family structure, which plays a more powerful role than childhood family poverty. Albeit smaller, some of the detrimental effects are also found for children of mothers who gave birth in their early 20s. 相似文献
