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…
