Forecasting risk measures using intraday data in a generalized autoregressive score framework

A new framework for the joint estimation and forecasting of dynamic value at risk (VaR) and expected shortfall (ES) is proposed by our incorporating intraday information into a generalized autoregressive score (GAS) model introduced by Patton et al., 2019 to estimate risk measures in a quantile regression set-up. We consider four intraday measures: the realized volatility at 5-min and 10-min sampling frequencies, and the overnight return incorporated into these two realized volatilities. In a forecasting study, the set of newly proposed semiparametric models are applied to four international stock market indices (S&P 500, Dow Jones Industrial Average, Nikkei 225 and FTSE 100) and are compared with a range of parametric, nonparametric and semiparametric models, including historical simulations, generalized autoregressive conditional heteroscedasticity (GARCH) models and the original GAS models. VaR and ES forecasts are backtested individually, and the joint loss function is used for comparisons. Our results show that GAS models, enhanced with the realized volatility measures, outperform the benchmark models consistently across all indices and various probability levels.     

政府创业支持与国家创新绩效：文化价值观的调节效应

创业作为实现创新的过程，对创新绩效提升具有重要作用。文化价值观作为社会“软实力”的重要指标，能够对创新过程施加重要影响。以文化价值观作为调节变量，构建政府创业支持与国家创新绩效关系模型，并通过全球54个国家数据进行实证检验。结果发现，政府政策支持、资金可获得性对国家创新绩效具有显著正向影响，权力差距、个人主义、不确定性规避负向调节政策支持与国家创新绩效间的关系，个人主义正向调节资金可获得性与国家创新绩效间的关系，而男性气质不存在调节效应。研究结果对政府制定有效政策具有一定参考价值。

依据创新扩散理论与流程观，提出一种企业互联网融合（互联网与业务流程融合）测度模型，包括信息化管理影响因素和相关假设，并将互联网与价值链上业务流程融合规模作为互联网融合的度量标准。基于196家传统企业调查数据，采用Logistic模型和结构方程建模对样本数据进行对比分析，验证所提出的模型及假设，揭示企业实施互联网技术支持业务活动的状况，鉴别企业之间互联网融合差异的关键解释因素，同时提出一种研究企业实施互联网技术支持业务活动的新途径。     

A change of perceived innovativeness for contactless food delivery services using drones after the outbreak of COVID-19

This study aims to identify how behavioral intentions are formed in the context of drone food delivery services using the moderating role before and after the outbreak of COVID-19. A conceptual model including eight hypotheses was developed and tested based on the data of two consumer samples, one collected before and the other after the outbreak of COVID-19. The data analysis results showed that perceived innovativeness positively affects attitude. In addition, the attitude, the subjective norm, and perceived behavioral control have a positive influence on behavioral intentions. Lastly, the outbreak of COVID-19 played a moderating role in the relationship between the attitude and behavioral intentions.     

Performance appraisal: dimensions and determinants

Abstract

Using a sample of Spanish establishments in the manufacturing sector, this article analyses the determinants of the dimensions of performance appraisal. The dimensions examined are performance measures, who evaluates performance and frequency. The results show that the degree of autonomy of the workforce affects positively the use of subjective criteria. It is also more likely that performance appraisal is carried out by the supervisor in the presence of teams and internal promotions. Regarding the explanation of the frequency, teams affect negatively this dimension of performance appraisal.     

Bayesian learning with variable prior

How much can be learned from a noisy signal about the state of the world not only depends on the accuracy of the signal, but also on the distribution of the prior. Therefore, we define a general information system as a tuple consisting of both a signal technology and a prior. In this paper we develop a learning order for general information systems and characterize the order in two different ways: first, in terms of the dispersion of posterior beliefs about state quantiles and, second, in terms of the value of learning for two different classes of decision makers. The first class includes all agents with quasi-linear quantile preferences, and the second class contains all agents with supermodular quantile preferences.     

The IB/ IHRM interface: Exploring the potential of intersectional theorizing

Although the core concepts underlying IB and IHRM provide a common lexicon and epistemology, this commonality is often more implicit than explicit. We highlight not only the common ground but also the lack of critical dialogue between the two fields. This paper asks: What can each field learn from the other? What do scholars from IB learn from IHRM and vice versa? We identify a possible agenda and concerns regarding theory building as a basis for dialogue between the two fields.     

Buen Vivir: Degrowing extractivism and growing wellbeing through tourism

Abstract

Buen Vivir (BV) is a holistic vision for social and environmental wellbeing, which includes alternative economic activities to the neoliberal growth economy. This article looks at how tourism initiatives under a BV approach can lead to degrowth by drawing on a case study of how BV is put into practice through tourism in the Cotacachi County in Ecuador. We argue that by degrowing socially and environmentally damaging extractive sectors and growing alternative economic activities like community-based tourism, a BV approach could increase social and environmental wellbeing. We refer to LaTouche’s notion of degrowth as a matrix of multiple alternatives that will reopen the space for human creativity. This complements the notion of BV as a plural approach, and in turn works to decolonise the parameters of how we might understand degrowth. In the case of Cotacachi, the vision for tourism is based on the needs of the community, rather than to satisfy a Eurocentric ideal of development supported by a policy of extractivism. BV is key to how this community conceptualises the potentialities of tourism because it considers the wellbeing of the people and the environment. In this case, degrowth is a consequence of BV, rather than the objective.
