CAT bonds are of significant importance in the field of alternative risk transfer. Because the market of CAT bonds is not complete, the application of an appropriate pricing model is of high relevance. We apply different premium calculation models to compare them with regard to their predictive power. Without taking the financial crisis into account, a version of the Wang transformation model and the linear model are the most accurate ones. In contrast, under consideration of the financial crisis, all analyzed models are approximately equivalent. Furthermore, we find that CAT bond specific information does not improve out‐of‐sample results. 相似文献

- Nowadays, not‐for‐profit organizations and charities face the ageing of donors and a growing debate over monetary donation collection methods. They need to find solutions to attract younger generations of donors. Could this be done using the same methods applied to older generations? This present research investigates social representations (SRs) of giving by younger generations to understand how not‐for‐profit organizations and charities should approach them. The study focuses on SRs of a French sample of 276 individuals from Generation Y born between 1979 and 1991. It uses the free association technique. The results show paradoxical representations of giving. Institutionalization of giving is salient as representation of it as a freely consenting act. The paradox relies also in the strong presence of a relationship with others that parallels the gift as an individualistic choice.
- Generation Y individuals appear to be sociable, yet they evoke more sharing and solidarity than charity. Institutionalized forms of giving, particularly via charities and not‐for‐profit organizations, are rejected. These individuals seem to express their individuality through practices that resemble sharing rather than giving. From a managerial point of view, these results shed light on the factors liable to cause members of this generation to give, such as (i) the use of social networks, (ii) appealing to pleasure, festivities and efficiency rather than to guilt and duty, and (iii) encouragement to “work within the not‐for‐profit organization”.

This article documents change in periurban horticulture using repeat surveys in 1995 and 2004 of about 300 households around Muea, Cameroon. Real household incomes increased by 14%, with a large shift from farm to nonfarm income. Within agriculture, activity shifted from staple crops to horticulture, both for sale and in home consumption. In 1995, there were large remittances from farmers involved in periurban horticulture to their village of origin; in 2004 remittances continued and horticultural farmers were also heavily involved in informal financial associations. Periurban horticulture is disproportionately practiced by women and older workers, and plays an important and growing role in African livelihoods. 相似文献

Business historians have treated the emergence of large, modern,vertically integrated meatpacking firms in the second half ofthe nineteenth century as the economically rational and inevitableproduct of the industry's search for ways to maximize profitsthrough technological innovation, vertical integration, andthe achievement of economies of scale and scope. This is onlypart of the story, however. Society's efforts to force the industryto abate its environmental pollution through government regulationand private lawsuits also stimulated and shaped these processesof modernization. 相似文献

Zusammenfassung Innerhalb kürzester Zeit hat sich im Internet eine gro?e Bandbreite von Online-Communities entwickelt, als fester Bestandteil der Beziehungswelt vieler Kunden. Unternehmen k?nnen für die Markenführung der Zukunft das Thema Online-Communities nicht mehr ausklammern, finden sich aber h?ufig im Internetdschungel (noch) nicht zurecht. Um Bewertungsportale, Blogs, Social Networking Sites, Virtual Worlds etc. im Sinne der Marke verstehen und nutzen zu k?nnen müsse Markenmanager eine Reihe von Spielregeln erlernen und beachten.

The ability of futures markets to predict subsequent spot prices has been a controversial topic for a number of years. Empirical evidence to date is mixed; for any given market, some studies find evidence of efficiency, others of inefficiency. In part, these apparently conflicting findings reflect differences in the time periods analyzed and the methods chosen for testing. A limitation of existing tests is the classification of markets as either efficient or inefficient with no assessment of the degree to which efficiency is present. This article presents tests for unbiasedness and efficiency across a range of commodity and financial futures markets, using a cointegration methodology, and develops a measure of relative efficiency. In general, the findings suggest that spot and futures prices are cointegrated with a slope coefficient that is close to unity, so that the postulated long-run relationship is accepted. However, there is evidence that the long-run relationship does not hold in the short run; specifically, changes in the spot price are explained by lagged differences in spot and futures prices as well as by the basis. This suggests that market inefficiencies exist in the sense that past information can be used by agents to predict spot price movements. A measure of the relative degree of inefficiency (based on forecast error variances) is then used to compare the performance of different markets. © 1999 John Wiley & Sons, Inc.

We examine the effect of a federally-funded local infrastructure spending program on local unemployment rates. To address the likely funding endogeneity problem, we exploit variation in spending due to pork-barreling, and find that higher government expenditure on roads substantially reduces local unemployment. 相似文献

We develop Lancaster's model of consumer behaviour under product differentiation to analyse Schumpeterian creative destruction. Launching new products with novel characteristics enables firms to temporarily steal market share from rivals. Product launch is monitored by using trade marks, patents and research and development. The dataset covers a large sample of UK service and manufacturing firms. We find that stock market value is positively associated with own trade mark activity and trade mark‐active firms achieve significantly higher value‐added. Greater trade mark activity by competitors reduces net output of firms, but raises their stock market value. This is consistent with the Schumpeterian process of competition through innovation. 相似文献

This article contrasts the characteristic structural and control profiles of educational organizations with those of technical organizations. A group of primary and secondary schools and the operating units of an industrial firm differed both in structural variables and in three activities of control: buffering, smoothing, and forecasting. the article suggests that educational organizations emphasize modes of control that operate on components peripheral rather than central to the organization's technical core. 相似文献
