We propose a novel class of convex risk measures, based on the concept of the Fréchet mean, designed in order to handle uncertainty which arises from multiple information sources regarding the risk factors of interest. The proposed risk measures robustly characterize the exposure of the firm, by filtering out appropriately the partial information available in individual sources into an aggregate model for the risk factors of interest. Importantly, the proposed risks can be expressed in closed analytic forms allowing for interesting qualitative interpretations as well as comparative statics and thus facilitate their use in the everyday risk management process of the insurance firms. The potential use of the proposed risk measures in insurance is illustrated by two concrete applications, capital risk allocation and premia calculation under uncertainty. 相似文献

The intersection of tourism and climate change has seen significant research over the past two decades, focusing particularly on issues of mitigation and adaptation in the global North. Research output has predominantly been centred on the Mediterranean and Nordic countries and number of localities in North America. The global South has seen significantly less investigation, despite having significantly lower adaptive capacity to the impacts of climate change, and numerous countries with rapidly growing tourism sectors. The African continent specifically has seen appreciably less research than other countries in the global South, despite arguably having the lowest adaptive capacity and projections of severe impacts of climate change to the tourism sector from temperature increases, changes in precipitation volume and sea level rise. This paper therefore presents a review of the existing literature on adaptation strategies of tourism sectors and participants in African countries. The crucial argument of this paper is in highlighting the need for an increase in research into the threats of climate change to tourism in African countries, identifying future research trajectories. The development of such knowledge would assist in the development of adaptation and mitigation strategies for these most vulnerable tourism economies. 相似文献

ABSTRACTTourists’ hotel event experiences have received little attention in tourism research. By proposing an integrated model of expectation–confirmation theory (ECT) and the experience economy concept, this research explores the relationship between tourists’ event experience and their satisfaction regarding the hotel event setting. The hypothesized model was empirically validated using a sample of 663 tourists who experienced a holiday event at a resort hotel. Results confirmed that the integration of the experience economy and ECT provided a better understanding of tourists’ post-satisfaction in a pleasure-driven setting. This affective–cognitive approach advances the knowledge of tourists’ experiences and satisfaction at hotel events. 相似文献

In this work, we simulate the effects of the tax autonomy of the Austrian states on the levels of public employment in each state. We show that depending on the strength of the public sector lobby, tax autonomy would require a reduction of employment in the public sector of between 25 and 35% of the current level. We also show that tax autonomy increases welfare levels by 1–1.5%; that is, the positive change in the disposable income of the workers more than offsets the welfare loss resulting from the lower provision of public goods. Finally, we show that the reduction of public employment is superior in terms of welfare to an alternative scenario in which employment levels are held constant but the wage levels in the public sector are adjusted. 相似文献

The conflicts of interest among managers, shareholders and creditors resulting in agency costs, can be mitigated by restricting managers’ adverse behavior, through financial covenants to better align the various stakeholder interests. Thus, debt contract strictness represents an important aspect of agency costs between creditors, shareholders, and management that is not always captured by interest rates. The contract setting provides a unique opportunity to investigate how creditors may rely on auditors to alleviate information uncertainty stemming from reliance on management's financial reporting and thus alleviate the creditor's potential loss of invested capital. After controlling for borrower risks, loan characteristics, and audit factors, we show that auditor industry specialization is significantly associated with a reduction in the strictness of debt contracts, consistent with creditors viewing certain industry expert auditors as effective monitors against financial reporting manipulation aimed at the avoidance of debt covenant triggers that protect creditors against potential loss. Further, we find that the association between loan strictness and auditor specialization is attenuated by stronger corporate governance systems, external monitors, and prior lender relationships. 相似文献

With increased regulatory focus on audits and concerns about whether audit regulation is achieving its stated aims, it is timely to investigate how regulator inspection of audit files and partner rotations may be affecting staffing decisions. This is an important issue, which affects all audits, as the calibre of staff allocated across engagements impacts the quality of audit work delivered. This study reports the results of an experiment where auditor participants allocate staff across two audits, where regulation anticipated (none, inspection, rotation) and a client request for the best staff (absent, present) are manipulated between‐subjects. We find that auditors allocate lower calibre staff when neither an inspection nor rotation is anticipated than when either is anticipated. When an inspection is anticipated, auditors allocate staff with more knowledge and compliance skills. When a rotation is anticipated, auditors allocate staff with more people skills. A client request for the best staff only has an effect when a partner is due to be rotated, where auditors allocate staff with more people skills in response to the client request. Our findings provide greater understanding of staffing decisions, which may affect audit quality if concerns around audit inspections and partner rotations are perceived by auditors as more important than the underlying risk or complexity of an engagement when allocating staff. 相似文献

This study quantifies the moral hazard effect of health insurance on medical expenditure by estimating a dynamic model of within‐year medical care consumption that allows for insurance selection, endogenous health transitions, and individual uncertainty about medical care prices in an environment where insurance has nonlinear cost‐sharing features. The results suggest that moral hazard accounts for 53.1%, on average, of total annual medical expenditure when insured. This estimate is significantly different, and generally larger, than that produced by an alternative model that is representative of the annual medical care decision‐making models commonly found in the literature. 相似文献

This paper studies the combined effect of affiliation with prestigious universities, underwriters, and venture capitalists on the valuation of biotech ventures at IPO and their post-IPO performance. We argue that affiliation to a prestigious university provides the affiliated firm with a quality signal in the scientific domain. The pure quality signaling effect of the affiliation is isolated from the substantive benefits it provides by performing a difference-in-difference approach based on the scientific reputation of scientists in firms' upper echelons. The signal is stronger the weaker is the scientific reputation of scientists of the focal IPO-firm and is additive to those provided by prestigious venture capitalists and underwriters. Results for a sample of 254 European biotech ventures that went through an IPO between 1990 and 2009 confirm our predictions. 相似文献

Integrating agency and institutional perspectives, we describe how China’s socio-political institutions create state-owned corporate empires with unique agency conflicts. We develop a framework demonstrating how economically unjustified firm expansion, i.e. empire building, mediates the relationship between state ownership and performance. We uncover the instrument in empire building and appropriate corporate governance and strategic management remedies. An empirical study on 29,638 Chinese firms evidences that (1) increased state ownership drives higher management expenses and lower firm profitability though empire building; (2) long-term debt is used to finance empire building; and (3) foreign capital investments and innovativeness can mitigate these agency conflicts. 相似文献
