摘要翻译:
预测成本现在是经验经济学的前沿。我们提出了一个非常规的工具,用于基于记录事件的个别(微观)发展来随机预测未来的费用。考虑一个公司、企业、机构或国家,它拥有关于特定历史事件的知识。对于每一个事件,都有一系列相关的子事件:支付或损失随着时间的推移而蔓延,所有这些都导致了一个无限随机的过程。然而,问题是一些已经发生的事件不一定要报告。其目的在于预测来自已报告、已发生但未报告以及尚未发生的事件的未来子事件流。我们的方法在定量风险评估方面得到了说明,但它也可以应用于其他领域,如创业、流行病、战争损害、广告和商业、数字支付或药物处方。作为一个理论贡献,无限随机过程的推理得到了发展。特别地,使用了以非齐次Poisson过程为标记的非齐次Poisson过程,它包括例如Cox过程作为特例。

英文摘要:
Forecasting costs is now a front burner in empirical economics. We propose an unconventional tool for stochastic prediction of future expenses based on the individual (micro) developments of recorded events. Consider a firm, enterprise, institution, or state, which possesses knowledge about particular historical events. For each event, there is a series of several related subevents: payments or losses spread over time, which all leads to an infinitely stochastic process at the end. Nevertheless, the issue is that some already occurred events do not have to be necessarily reported. The aim lies in forecasting future subevent flows coming from already reported, occurred but not reported, and yet not occurred events. Our methodology is illustrated on quantitative risk assessment, however, it can be applied to other areas such as startups, epidemics, war damages, advertising and commercials, digital payments, or drug prescription as manifested in the paper. As a theoretical contribution, inference for infinitely stochastic processes is developed. In particular, a non-homogeneous Poisson process with non-homogeneous Poisson processes as marks is used, which includes for instance the Cox process as a special case.
