I suggest a model to forecast life expectancy based on the electrocardiogram signal. I show how the heart electrical activity can be decomposed in the state‐space and that the suggested model has superior out‐of‐sample properties compared to a set of alternatives. When the model is used to forecast my own electrocardiogram, a striking result arises: the n‐step ahead forecast remains bounded and positive even after one googol period. Therefore, my life expectancy tends to infinity implying that I am immortal. (JEL I10, I19) 相似文献

This paper develops an evidence-based approach to the selection and prioritisation of Next Generation EU (NGEU) projects for timely implementation and impact of the Recovery Plan for Europe. The analysis of a large sample of projects, currently funded by the European Union (EU) with the same priorities and objectives of NGEU, suggests that a timely implementation should be driven – within the EU Commission coordination framework – by national governments liaising directly with their citizens through participatory procedures, involving relevant stakeholders. Simplified implementation procedures with clear spatial targeting and limited involvement of regional authorities are necessary conditions for the avoidance of implementation delays. 相似文献

In this paper we investigated the use of attrition weights to cope with non-response when selecting graphical chain models
for longitudinal data. We proposed a parametric bootstrap approach to account for the extra variability introduced by the
estimation of the weights and compared this with results using standard test procedures. 相似文献

Scholars and practitioners have recently devoted considerable attention to boards of directors, but far more research is needed.
We still know little about how boards actually work and how their behavior may be improved to contribute to value creation.
During more than two decades agency theory has been the dominant theory in studies about boards of directors. When relaxing
some of the assumptions in agency theory several new pathways for new research arise. To present new perspectives on board
research we follow in this essay some of the pathways arising from relaxing agency theory assumptions about complete contracts.
Alternative theoretical approaches, research questions and methods are suggested. 相似文献

The current paper constructs a progress measurement appropriate for measuring multiple and different dimensions of progress.
The paper is not meant to be a detailed discussion of the framework but rather a demonstrated application of the measure.
The constructed resource-infrastructure-environment progress measure employs a non-monetary evaluation adopting a weighting
technique based on public opinion. The proposed index is assessed from a single summary standpoint. The aggregation method
is evaluated via a z-score standardisation technique. The progress index is applied to three countries that are representative
of different clusters. They are Australia (mid-industrialised nation), Mexico (emerging economy), and the US (highly industrialised
nation). These selected countries provide an opportunity to highlight any divergences that may exist in their perceived economic
strength. The results showed Australia as consistently having the highest levels of progress, closely followed by Mexico and
then the US. 相似文献

The European Union Statistics on Income and Living Conditions (EU-SILC) is the main source of information about poverty and economic inequality in the member states of the European Union. The sample sizes of its annual national surveys are sufficient for reliable estimation at the national level but not for inferences at the sub-national level, failing to respond to a rising demand from policy-makers and local authorities. We provide a comprehensive map of median income, inequality (Gini coefficient and Lorenz curve) and poverty (poverty rates) based on the equivalised household income in the countries in which the EU-SILC is conducted. We study the distribution of income of households (pro-rated to its members), not merely its median (or mean), because we regard its dispersion and frequency of lower extremes (relative poverty) as important characteristics. The estimation for the regions with small sample sizes is improved by the small-area methods. The uncertainty of complex nonlinear statistics is assessed by bootstrap. Household-level sampling weights are taken into account in both the estimates and the associated bootstrap standard errors. 相似文献

An organization’s survival and its performance are often connected to employees’ well-being, which in intensive work conditions can be compromised by employee exhaustion. To date, the last economic crisis has forced several companies to downsize and leave the remaining employees facing higher job demands and vulnerability toward job exhaustion. The present study investigates whether resilience together with other personal resources can function as a psychological shield through a mediation and/or moderation process that mitigate the emergence of burnout. Based on a sample of employees from three different Italian companies (N?=?208), our results confirmed that “resilience resources” (i.e., resilience, self-efficacy, self-regulation) mediated the relationship between job demands, exhaustion, and task performance (i.e., energetic process). These results suggest that organizational environments characterized by challenging demands are likely to foster the development of resilience resources to cope with the emergence of potentially harming processes. 相似文献
