ABSTRACTAccurate estimation of value-at-risk (VaR) and assessment of associated uncertainty is crucial for both insurers and regulators, particularly in Europe. Existing approaches link data and VaR indirectly by first linking data to the parameter of a probability model, and then expressing VaR as a function of that parameter. This indirect approach exposes the insurer to model misspecification bias or estimation inefficiency, depending on whether the parameter is finite- or infinite-dimensional. In this paper, we link data and VaR directly via what we call a discrepancy function, and this leads naturally to a Gibbs posterior distribution for VaR that does not suffer from the aforementioned biases and inefficiencies. Asymptotic consistency and root-n concentration rate of the Gibbs posterior are established, and simulations highlight its superior finite-sample performance compared to other approaches. 相似文献

This paper investigates whether the accrual anomaly reported in prior studies exists across both profit and loss firms. We
posit that the extent of accrual mispricing is less severe for loss firms than for profit firms because earnings for loss
firms are less value relevant and, therefore, less subject to accrual mispricing. As expected, we find that the accrual overpricing
anomaly is restricted to profit-making firms and, thus, is dampened by the inclusion of loss firms in the sample. Furthermore,
we report that accrual overpricing for profit firms but not for loss firms is primarily attributable to the overpricing of
positive accruals of profit firms compared with those of loss firms. Finally, we find that the phenomenon of accrual overpricing
for profit but not for loss firms may persist into the new regulatory environment following the passage of the Sarbanes–Oxley
Act of 2002. 相似文献

The demand for housing is heavily influenced by access to employment opportunities. The cost of gasoline determines, in part, the cost of such access and therefore the relative demand across markets with varying commuting needs. Locally exogenous gasoline price movements demonstrate the causal impact of higher fuel costs on housing markets: a shift of market demand toward real estate markets with less costly commutes. Higher fuel prices increase the value of real estate with shorter commutes and easier access to driving alternatives relative to more driving dependent homes. Every incremental $1 per gallon of gasoline reduces home values by 0.143% for every additional mile relative to counterfactual markets, or $5,200 for the average home and commute. This translates into a discount rate of 6.4%, comparable to mortgage rates for the period. 相似文献

Eco‐innovations are an effective way for companies to strategically align themselves with customers’ growing environmental concerns. Despite their crucial role, scant research has focused on eco‐innovative product designs. Drawing from the sustainability and innovation literature, this article proposes that in the design of an eco‐innovation, its degree of innovativeness, level of eco‐friendliness, and detachability significantly affect consumers' adoption intentions. This article develops various conceptual models tested through three independent online experiments with U.S. consumers. The findings support the hypotheses and provide useful insights into the underlying mechanisms of how and why consumers respond to eco‐innovative product designs across various high‐tech product categories. Specifically, the results show (1) a positive effect of innovativeness degrees of eco‐innovative attributes on consumers' perceptions of product eco‐friendliness and on their adoption intentions as well as a significant moderating role of consumers' need for cognition (Study 1); (2) a positive influence of eco‐friendliness levels of eco‐innovative attributes on consumer adoption intentions in the case of high‐complexity products but not for low‐complexity products, emphasizing the need to adopt different approaches when developing eco‐innovations to ensure favorable consumer reactions (Study 2); and (3) a significant impact of the detachability of eco‐innovative attributes on consumers' perceptions of trade‐offs between environmental benefits and product functionality and on their intentions to adopt eco‐innovations (Study 3). These findings add to existing theoretical knowledge, provide actionable managerial implications, and identify fruitful avenues for future research. 相似文献

Slow growth over the last decade has prompted policy attention towards increasing R&D spending, often via the tax system. We examine the impact of R&D on firm performance, both by the firm's own investments and through positive (and negative) spillovers from other firms. We analyse panel data on US firms over the last three decades, and allow for time‐varying spillovers in both technology space (knowledge spillover) and product market space (product market rivalry). We show that the magnitude of R&D spillovers remains as large in the second decade of the 21st century as it was in the mid 1980s. Since the ratio of the social return to the private return to R&D is about four to one, this implies that there remains a strong case for public support of R&D. Positive spillovers appeared to temporarily increase in the 1995–2004 digital technology boom. We also show how these micro estimates relate to estimates from the endogenous growth literature and give some suggestions for future work. 相似文献
