Kapitel I. Bibliographisches

Die versicherungstechnische Litteratur hat sich verhältnismässig wenig mit den aktuariell-finanziellen Fragen befasst. Bemerkenswert ist es deshalb, dass die meisten von den bis jetzt abgehaltenen neun internationalen Aktuarkongressen die eine oder die andere Frage aus oben erwähntem Gebiet in ihrem Programm aufgenommen haben. So z. B. beschäftigte sich der erste Kongress, der 1895 in Brüssel tagte, mit dem Gegenstand: “Des mesures qui pourraient être prises par les institutions qui contractent des engagements à long terme, pour se premunir contre les conséquences des variations du taux d intérêt.” Der Kongress im Jahre 1900 in Paris hatte in seinem Programm das Thema: “Méthodes à employer pour evaluer les titres mobiliers compris dans l'actif d'une Société quelconque.” Bei dem New Yorker Kongress 1903 wurde die Prage über “The Probable Future Course of the Rate of Interest” erörtert. Dem Wiener Kongress 1909 war die Frage über “Kapitalsanlagen der Versicherungsgesellschaften mit besonderer Berücksichtigung der modernen Entwickelung” zur Behandlung vorgelegt. Das Programm des Londoner Kongresses 1927 enthielt das Thema “Currency Depreciation as affecting Life Assurance Contracts”.  相似文献

We model the dynamics of ask and bid curves in a limit order book market using a dynamic semiparametric factor model. The shape of the curves is captured by a factor structure which is estimated nonparametrically. Corresponding factor loadings are modelled jointly with best bid and best ask quotes using a vector error correction specification. Applying the framework to four stocks traded at the Australian Stock Exchange (ASX) in 2002, we show that the suggested model captures the spatial and temporal dependencies of the limit order book. We find spill-over effects between both sides of the market and provide evidence for short-term quote predictability. Relating the shape of the curves to variables reflecting the current state of the market, we show that the recent liquidity demand has the strongest impact. In an extensive forecasting analysis we show that the model is successful in forecasting the liquidity supply over various time horizons during a trading day. Moreover, it is shown that the model's forecasting power can be used to improve optimal order execution strategies.  相似文献

The implementation of structural adjustment programs (SAPs) has often been undermined by opposition from politically powerful groups who are favored by existing policies. To assess the political sustainability of SAPs this paper uses social accounting matrices for three African countries to model the income effects of stylized SAPs on different socioeconomic groups. The analysis reveals wide variation in the likelihood for typical SAPs to be acceptable to political elites while generating growth in the rest of the economy. The presence of a rural elite or strong farm-nonfarm linkages can enhance the political sustainability of SAPs.  相似文献

This paper presents a critical discussion of the internationally prevailing understanding of the concept 'sustainable tourism'. It is argued that the current focus on stationary activities and local, intensive environmental issues is too limited both in relation to the concept of tourism and the concept of sustainable development. There is no tourism without travel. And, as shown in a Norwegian research study, tourist travel is a major source of serious environmental problems. The paper emphasises that sustainable tourism should be linked to a concept of sustainable mobility. However, this mobility would imply not only a change in the means of transport but also a reduced level of mobility in the rich part of the world. As this would entail new forms of tourism, other than those solely based on auto- and aeromobility, it represents a major challenge for the future development of tourism.  相似文献

Conference Tourism: A Problem for the Environment,as well as for Research?   总被引:1,自引:0,他引:1  
The increase in professional trips to conferences and seminars made by employees in the 'knowledge industries' presents an environmentally worrying trend in mobility in contemporary post-industrial society. A number of factors are involved. Globalisation and regional competition encourage host cities and institutions to put themselves on the conference map. For the individual traveller, conferences and seminars offer escape from daily routines and the chance to experience new, perhaps exotic, places. But trips to distant conferences can have serious environmental impacts, especially if made by airplane. Because of the aggressive impact of greenhouse gas emissions in the upper atmosphere, their threat to the global climate is more serious than similar trips made at surface level. In addition, the time spent on such trips competes with other tasks: conference participation takes scarce time resources available to university academics for research. In the age of electronic communication, it is questionable whether conferences are effective arenas for communicating and gathering knowledge.  相似文献

Khat-chewing, a controversial leisure activity within the Somali diaspora in Britain, has received little attention within the academic field of Leisure Studies. This paper reports on ethnographic research to provide insights into the unique locations where young British-Somali men chew khat, exposing the liminal qualities of such localities. The paper begins with an overview of the contentious position khat-chewing occupies within Somali communities in Britain, highlighting reasons why young British-Somali men hide their association with the leisure practice. The discussion that follows considers how young male khat users conceptualise spatial environments, exposing how these locations temporarily produce a dual sense of privacy and sociality. The ambiences of such temporary leisure spaces remain open to the prospect of discovery, resulting in the use of discretionary tactics to maintain a sense of secrecy. In this context, we discuss how khat-chewing offers a sense of cultural identity and belongingness while also marking young British-Somali men as outsiders – even within their own communities.  相似文献

Zusammenfassung Feldstein lenkt die Aufmerksamkeit von Politik und Ökonomie auf die Erhöhung der Steuerbelastung für die Unternehmungen, die bei Inflation durch die Abschreibung zu historischen Kosten (bei gleichem Steuertarif) entsteht. Er errechnet eine Formel für die Extrasteuer je Prozentpunkt Inflation, in der ein bestimmter effektiver Steuersatz eine Rolle (als Konstante) spielt. Dieser soll die Wirkung der weltweit üblichen Systeme der Investitionsbegünstigung (z. B. vorzeitige Abschreibung) berücksichtigen. Eine weitere Betrachtung dieser Systeme scheint dann nicht nötig, weil sie schon vor der Inflation geschaffen wurden. Tatsächlich hängt aber die Höhe des sogenannten effektiven Steuersatzes selbst von der Inflation ab. Der Wert der vorzeitigen Abschreibung steigt in der Inflation und wirkt der Steuererhöhung entgegen. Im Extremfall einer sofortigen vollen Abschreibung wird die Extrasteuer Null.Die stärkere Vorteilhaftigkeit der vorzeitigen Abschreibung in der Inflation (verglichen mit der Normalabschreibung zu historischen Kosten) läßt eine stärkere Ausnutzung der vorzeitigen Abschreibung im inflationären Fall erwarten. Gründe gegen die volle Ausnutzung dieser Begünstigung (fehlende Gewinne, Informationskosten) bei stabiler und inflationärer Preisentwicklung werden diskutiert.  相似文献

This paper investigates the relation between cross listing in the United States and the information environment of non‐U.S. firms. We find that firms that cross list on U.S. exchanges have greater analyst coverage and increased forecast accuracy than firms that are not cross listed. A time‐series analysis shows that a change in analyst coverage and forecast accuracy occurs around cross listing. We also document that firms that have more analyst coverage and higher forecast accuracy have higher valuations. Furthermore, the change in firm value around cross listing is correlated with changes in analyst following and forecast accuracy, suggesting that cross listing enhances firm value through its effect on the firm's information environment. Our findings support the hypothesis that cross‐listed firms have better information environments, which are associated with higher market valuations.  相似文献

Principals who delegate tasks to agents face the perennial challenge of overcoming agency problems. We investigate whether feelings of ownership among senior managers in the absence of formal ownership can align agents' interests with those of principals, thus turning agents into psychological principals. Using a moderated mediation model, we find that psychological ownership is positively related to company performance through the mediating effect of individual‐level entrepreneurial behaviour. We also find that the effect of psychological ownership on individual‐level entrepreneurial behaviour and, ultimately, company performance is weaker for high levels of monitoring compared to low levels. These findings offer important contributions to agency, psychological ownership, and entrepreneurship literatures.  相似文献
