The Inclusion of Socially Irresponsible Companies in Sustainable Stock Indices
2019
Social rating agencies implement complex filters to identify the companies with the best sustainable and social performance and help investors select the companies for their sustainable portfolios. This study analysed whether companies that are defined as ethical, sustainable and socially responsible by those agencies actually deserve this label. More specifically, the inclusion in the prestigious Dow Jones Sustainability Index (DJSI) World of companies that have been involved in controversies according to the Thomson Reuters Eikon database was studied. The results show that the inclusion of irresponsible companies in the DJSI Index is a fact. This outcome is in line with previous studies t…
Cost of Type 2 Diabetes Patients with Chronic Kidney Disease Based on Real-World Data: An Observational Population-Based Study in Spain
2021
[EN] This study analyzed the prevalence, costs and economic impact of chronic kidney disease CKD in patients with T2D in a Spanish Health District using real-world data. Observational cross-sectional study in adult patients with T2D was through data extracted from the information systems of the Valencia Clinico-La Malvarrosa Health District in the year 2015. Patients were stratified with the KDIGO classification for CKD. Additionally, patients were assigned to Clinical Risk Groups (CRGs) according to multimorbidity. Direct costs of primary and specialized care, and medication were estimated. The prevalence of T2D in the database population (n = 28,345) was 10.8% (mean age (SD) = 67.8 years …
Is the sustainability profile of FinTech companies a key driver of their value?
2022
[EN] The digitisation process is affecting all markets and raising consumer awareness about companies' sustainable behaviour. This work studies the effect of the sustainability profile of FinTech companies on the firm (market value and book value) as the factors that add value to investors and motivate their evolution in markets are still unknown. Using the KBW and Nasdaq FinTech Indices, and the NASDAQ Insurance Index (IXIS), we composed a panel of 95 companies over a 10-year period (2010-2019) with economic-financial variables and data about green certificates and sustainability indices. The applied methodology is based on dynamic (GMM-SYS) and static (PCSE) panel data models. Our results…
Corporate Governance Configurations and Corporate Social Responsibility Disclosure: Qualitative Comparative Analysis of Audit Committee and Board cha…
2020
[EN] Drawing on the complexity theory and responding to the recent calls to use such creative methods that mix between a quantitative and qualitative approach. Therefore, this study fills the literature gap, adding novelties, showing evidence from the unexplored (or underexplored) European context and, consequently, shedding light to inconclusive results in previous research concerning the effect of audit committee (AC) and board characteristics on corporate social responsibility (CSR) disclosure by applying a novel research methodology: the fuzzy set qualitative comparative analysis. The data were collected from Eikon database for a sample of the top 69 non¿financial European companies (ba…
Mass appraisal of residential real estate using multilevel modelling
2016
Mass appraisal, or the automatic valuation of a large number of real estate assets, has attracted the attention of many researchers, who have mainly approached this issue employing traditional econometric models such as Ordinary Least Squares (OLS). However, this method does not consider the hierarchical structure of the data and therefore assumes the unrealistic hypothesis of the independence of the individuals in the sample. This paper proposes the use of the Hierarchical Linear Model (HLM) to overcome this limitation. The HLM also gives valuable information on the percentage of the variance error caused by each level in the hierarchical model. In this study HLM was applied to a large dat…
A Compact Representation of Preferences in Multiple Criteria Optimization Problems
2019
A critical step in multiple criteria optimization is setting the preferences for all the criteria under consideration. Several methodologies have been proposed to compute the relative priority of criteria when preference relations can be expressed either by ordinal or by cardinal information. The analytic hierarchy process introduces relative priority levels and cardinal preferences. Lexicographical orders combine both ordinal and cardinal preferences and present the additional difficulty of establishing strict priority levels. To enhance the process of setting preferences, we propose a compact representation that subsumes the most common preference schemes in a single algebraic object. We …
Chemometrics as a tool to discriminate geographical origin of Cyperus esculentus L. based on chemical composition
2013
[EN] In the present study the chemical composition of Cyperus esculentus L. (tiger nut) from four distinct geographical origin (Spain, Egypt, Nigeria, and South Africa) was assessed to observe the possible effect of the cultivation site in the fatty acids profile, sterols composition, and squalene and -tocopherol content. It was verified that the individual fatty acids as well as the different fatty acids fractions were severely affected by the geographical origin. Tiger nut oils were predominantly monounsaturated with lower prevalence of saturated fatty acids, and with capability to provide appreciable amounts of essential fatty acids. The sterols fraction was affected as well, but in lowe…
Multiple-criteria cash-management policies with particular liquidity terms
2019
Abstract Eliciting policies for cash management systems with multiple assets is by no means straightforward. Both the particular relationship between alternative assets and time delays from control decisions to availability of cash introduce additional difficulties. Here we propose a cash management model to derive short-term finance policies when considering multiple assets with different expected returns and particular liquidity terms for each alternative asset. In order to deal with the inherent uncertainty about the near future introduced by cash flows, we use forecasts as a key input to the model. We express uncertainty as lack of predictive accuracy and we derive a deterministic equiv…
Constructing the Audit Risk Assessment by the Audit Team Leader When Planning: Using Fuzzy Theory
2021
The aim of this study is to construct the assessment of the expected audit risk by the audit team leader (ATL) during the planification phase of the audit. The ATL plays an important role within the audit, and even more so regarding small and medium-sized (SME) audit firms. The audit risk assessment is critical as relying more (less) on internal controls implemented by the client leads to performing less (more) substantive audit procedures. This is determined by the ATL based on their professional judgement and previous experience. The use of fuzzy theory has powerful potential into the audit arena, as the audit risk assessment (outcome) is critically related to the auditors’ judgement and …
Bibliometric analysis of the international literature on open innovation and absorptive capacity
2016
Objecte: Comprovar si existeix, i si ha estat estudiada o demostrada, l’estreta relació, suggerida per alguns autors, entre innovació oberta i capacitat d’absorció. Disseny/metodologia: Anàlisi bibliomètrica sobre la Web of Science de la literatura internacional on es tracten ambdós termes simultàniament. Aportacions i resultats: S’ha demostrat que és un camp de creixent interès i que existeix una estreta relació entre innovació oberta i capacitat d’absorció. Limitacions: Els biaixos propis de utilitzar la base de dades elegida i els criteris de selecció aplicats fan possible la no inclusió d’algun article significatiu. Implicacions pràctiques: Conèixer que la capacitat d’absorció té relaci…
