We propose a Bayesian model to quantify the uncertainty associated with the payments per claim incurred (PPCI) algorithm. Based on the PPCI algorithm, two submodels are proposed for the number of reported claims run-off triangle and the PPCI run-off triangle, respectively. The model for the claims amount is then derived from the two submodels under the assumption of independence between the number of incurred claims and the PPCI. The joint likelihood of the number of reported claims and claims amount is derived. The posterior distribution of parameters is estimated via the Hamiltonian Monte Carlo (HMC) sampling approach. The Bayesian estimator, the process variance, the estimation variance, and the predictive distribution of unpaid claims are also studied. The proposed model and the HMC inference engine are applied to to an empirical claims dataset of the WorkSafe Victoria to estimate the unpaid claims of the doctor benefit. The Bayesian modeling procedure is further refined by including a preliminary generalized linear model analysis. The results are compared with those in a PwC report. An alternative model is compared with the proposed model based on various information criteria. 相似文献

转型期中国,地方国有企业作为地区经济发展的一股中坚力量,当其发生债务违约时,作为实际控制人的地方政府究竟是否愿意提供支持,会优先选择哪些企业提供支持,政府的支持行为是否会影响到信贷资源的配置效率呢?为得到验证,文章选取2007-2016年沪深A股地方国有上市企业作为研究样本,实证分析了地方国企发生债务违约后,地方政府的支持行为及其对信贷资源配置效率的影响。研究结论表明:第一,地方国企发生债务违约后,地方政府会提供更多的"支持",且支持额度与债务违约额呈显著正相关关系;第二,债务违约前,承担了更多社会责任(环保投资、捐赠以及就业等)的地方国企,在债务违约后可相应地获得更多的地方政府支持;第三,违约企业,尤其是得到更多政府支持的违约企业可获得更多的信贷资源,而其经营业绩却往往更差。由此表明政府干预一定程度上降低了信贷资源配置效率。 相似文献

Little research has investigated the effect of ownership identity (or type) and corporate philanthropy experience on giving. In this research, relying on legitimacy theory, we first assess the effect of ownership identity on corporate philanthropy (CP) in the context of the 2008 earthquake in China. Then we explore moderation effects of firms' prior CP experience and size as proxies for perceived legitimacy on owners' efforts at increasing giving and legitimacy. We find that state and CEO ownership are deterrents, while non‐SOE and institutional ownership enhances giving probability and amount. In addition, there is evidence that firm size and prior CP weaken the effects of institutional ownership on CP. This study provides a complete assessment of owner behaviour. Copyright © 2018 ASAC.

This paper examines the effects of idiosyncratic accounting information on a firm's cost of capital. By embedding a moral hazard problem into a multifirm asset‐pricing model, I show that moral hazard distorts the sharing of idiosyncratic risk but does not affect the sharing of systematic risk in the economy. A firm‐level improvement in idiosyncratic information reduces the firm's cost of capital even though it does not affect the implied cost of capital inferred from publicly traded shares. Moreover, an economy‐level improvement in idiosyncratic information reduces the risk premium for idiosyncratic risk but increases the risk premium for systematic risk, resulting in an ambiguous net effect on the firm's cost of capital. These results provide alternative explanations for the mixed empirical evidence on the relation between information quality and the cost of capital. 相似文献

以创新生态系统为视角,引入创新资源互动与生态系统规范机制为中介变量和调节变量,探究价值共创如何影响企业创新绩效。基于307家企业样本数据,运用结构方程模型、Bootstrap和层级回归方法对数据进行分析。研究发现:创新生态系统中,价值共创不完全直接影响企业创新绩效;创新资源互动部分中介价值共创对企业创新绩效的影响;生态系统规范机制部分正向调节价值共创对创新资源互动的影响。最后提出,创新生态系统调控方与企业要差异化地制定提升创新绩效的实施方案,营造活跃的创新资源互动氛围,形成并完善系统内生态规范机制。 相似文献

Studies on the legitimacy challenges faced by hi-tech start-ups are still scarce, leaving room for research, and policymaking debate. Legitimacy issues may become difficult to face for hi-tech firms in comparison with other start-ups, because they work in an extreme environment where the technological challenges are at the edge of the scientific possibility. The paper proposes a conceptual model to grasp the relevance of three legitimacy drivers of the hi-tech start-ups for investment decisions. We investigated the ability of 30 hi-tech start-up firms to obtain financial resources from the US investors, employing a set-theoretic approach and carried out fuzzy-set Qualitative Comparative Analysis. Our findings clarify that the funding decisions of US investors are driven by the location of headquarter and R&D of hi-tech start-ups and by the educational experience of the founders. Our study has significant theoretical, practical, and policymaking implications. 相似文献

This paper develops a platform‐based influencing factors model which considers value perception, risk prevention measure, non‐default experience, trust and incentive gap, to better examine the impact of platforms on investors’ satisfaction and lending intention based on the Chinese market. The results reveal that the first four factors positively influence the satisfaction of the investors, while the incentive gap has a negative impact, and there is a positive association between investors’ satisfaction and lending intention. Some specific features of China’s online lending market are identified, which provides valuable insights for online lending platforms and the government. 相似文献

This study proposes a hybrid information approach to predict corporate credit risk. In contrast to the previous literature that debates which credit risk model is the best, we pool information from a diverse set of structural and reduced‐form models to produce a model combination based on credit risk prediction. Compared with each single model, the pooled strategies yield consistently lower average risk prediction errors over time. We also find that while the reduced‐form models contribute more in the pooled strategies for speculative‐grade names and longer maturities, the structural models have higher weights for shorter maturities and investment grade names. 相似文献
