In this article, we derive conditions in an imperfect market setting, under which the introduction of a self‐supporting insurance guaranty fund improves the position of the policyholders. When a guaranty fund is advantageous given homogeneous firms in the market, all policyholders benefit from it to the same extent, if they have the same underlying risk preferences and are charged identical premiums. In a more realistic heterogeneous setting, the introduction of an insurance guaranty fund is in general no longer beneficial for all policyholders in the same manner. Hence, systematic wealth transfers take place between the policyholders of different insurance companies. As a possible solution, and in order to counteract this effect, we introduce a framework for utility‐based fund charges.  相似文献

In this paper, we present a new methodology for modelling intraday volume, which allows for a reduction of the execution risk in VWAP (Volume Weighted Average Price) orders. The results are obtained for all the stocks included in the CAC40 index at the beginning of September 2004. The idea of considered models is based on the decomposition of traded volume into two parts: one reflects volume changes due to market evolution; the second describes the stock specific volume pattern. The dynamic of the specific volume part is depicted by ARMA and SETAR models. The implementation of VWAP strategies allows some dynamic adjustments during the day in order to improve tracking of the end-of-day VWAP.  相似文献

As genetically modified (GM) products approach the market stage, the UK government and agro-food industry have faced a suspicious or hostile public. Since 1998 many retail chains have undertaken to exclude any GM-derived ingredients from their own-brand lines. This commercial blockage has intensified pressures for greater precaution, even for a moratorium on cultivating GM crops. Political protest has led to strategies for precautionary commercialization. Government and industry have cooperated to plan a ‘managed development’ of GM crops. Across the agricultural supply chain, industry has devised voluntary guidelines to ensure segregation of GM crops and to limit the spread of GM herbicide-tolerance. In particular UK regulators seek to test the risk that broad-spectrum herbicide sprays could damage wildlife habitats; they have broadened the advisory expertise accordingly. These measures open up the precautionary content to further debate, at both national and EU levels. Market-stage precautions establish a means to test claims that GM crops are environmentally-friendly products. By translating public concerns into broader risk-assessment criteria, the UK procedure involves critics in potentially influencing standards of scientific evidence and environmental harm. This social process has become a prerequisite for legitimizing commercial use.  相似文献

We introduce multiperiod mortgage loans, fixed interest rate, a lower bound constraint on newly granted loans, and a possibly slack collateral constraint, in an otherwise standard Dynamic Stochastic General Equilibrium (DSGE) model with housing. Our nonlinear estimation shows that all those features are important to understand the evolution of mortgage debt during the recent U.S. housing market boom and bust. The transmission of monetary policy becomes dependent on the housing cycle, with weaker effects when house prices are high or start falling sharply. Higher average loan duration makes monetary policy less effective, eventually leading to asymmetric responses to positive and negative monetary shocks.  相似文献

The aim of this article is to evaluate the external and internal factors motivating the selection of business services to be outsourced by key meeting-industry (business tourism) players, with a particular focus on knowledge-intensive business services. The case-study method was adopted in the article to analyze the motivation behind outsourcing of knowledge-intensive business services by meeting venues and event companies in Krakow (Poland). The results confirm that event companies tend to subcontract out core services connected with the organization, promotion and/or management of events, event services, and technical support for events.  相似文献

The recent years have been a time of rapid development of information and communication technologies (ICTs) in tourism. The objective of this article is to analyse and assess the use of ICTs in tourist information and promotion of selected municipalities in the Polish Carpathians, the largest region of mountain tourism in Poland. Particular attention was paid to the activities taken by DMOs, local entrepreneurs and cultural institutions. The use of ICTs in the Polish Carpathians is at a relatively advanced level, but still not sufficient enough to make these solutions a fully effective tool in building a strong regional brand in the international tourism markets.  相似文献

Patent applications by male New Zealand inventors sharply increased in the early 1880s after initial official fees were reduced, and the requirement to advertise applications in newspapers abolished. Increasingly, however, applications lapsed, while applications by unskilled workers remained low. Non-fee costs were crucially important, with the 1870 reduction in fees failing to increase patenting, as hoped, because the doubling of mandatory advertising costs negated the fees reduction. Patenting by overseas inventors was less affected by fees, and steadily grew. Only one application was by an indigenous Māori person, while even in 1899 women made just 2.5% of applications.  相似文献

The authors argue that it is possible to partly automate the process of abstract control of fairness of clauses in online consumer contracts. The authors present a theoretical and empirical argument for this claim, including a brief presentation of the software they have designed. This type of automation would not replace human lawyers but would assist them and make their work more effective and efficient. Policy makers should direct their attention to the potential of using algorithmic techniques in enforcing the law regarding unfair contractual terms, and to facilitating research on and ultimately implementing such technologies.  相似文献

We consider the portfolio choice problem for a long‐run investor in a general continuous semimartingale model. We combine the decision criterion of pathwise growth optimality with a flexible specification of attitude toward risk, encoded by a linear drawdown constraint imposed on admissible wealth processes. We define the constrained numéraire property through the notion of expected relative return and prove that drawdown‐constrained numéraire portfolio exists and is unique, but may depend on the investment horizon. However, when sampled at the times of its maximum and asymptotically as the time‐horizon becomes distant, the drawdown‐constrained numéraire portfolio is given explicitly through a model‐independent transformation of the unconstrained numéraire portfolio. The asymptotically growth‐optimal strategy is obtained as limit of numéraire strategies on finite horizons.  相似文献
