Dependence between renewable energy related critical metal futures and producer equity markets across varying market conditions
2022
We study the dependence of renewable energy production-related critical metal futures and producer equity returns, compared to the non-renewable energy (oil and natural gas) and some other globally relevant commodity markets. We find different asymmetric and symmetric dependencies in these commodity markets. The dependence is asymmetric in the most important critical metal markets, i.e., of silver, copper, and platinum. Still, surprisingly, for example, in the oil market, the relationship is symmetric, and no relationship is found in the natural gas market. Furthermore, the oil and agricultural markets have homogenous dependence structures in most market conditions, so the information trans…
Strategic Analysis Tools Application at SMEs in Ecuador
2015
This article explores the nature and scope of Strategic Analysis Tools (SAT) application in SMEs located in emerging countries such as Ecuador (where there are no formal studies on the subject). It is intended to assess which of the instruments utilized by these firms may contribute to formulate strategic options and which of them create awareness of relevant risks or distress specifically about continuity concerning their operations. Through the application of a survey to an intentional sample-selection of SMEs in Quito-Ecuador we analyzed the consciousness over these instruments to facilitate the creation of strategic options, their contribution to assess their competitive position and th…
Simple Strategic Analysis Tools at SMEs in Ecuador
2015
This article explores the possible applications of Strategic Analysis Tools (SAT) in SMEs located in emerging countries such as Ecuador (where there are no formal studies on the subject). It is intended to analyze if whether or not it is feasible to effectively apply a set of proposed tools to guide mental map decisions of executives when decisions on strategy have to be made. Through an in-depth review of the state of the art in regards to SAT and interviews performed to main participants such as chambers and executives of different firms, it is shown the feasibility of their application. This analysis is complemented with specialists´ interviews to deepen our insights and obtaining valid …
Como as práticas ecológicas e o desperdício de alimentos influenciam o capital de marca do restaurante?
2020
Resumen El presente trabajo tuvo por objetivo evaluar la incidencia de las prácticas verdes, la innovación sostenible y el manejo del desperdicio alimentario en la construcción del capital de marca de los restaurantes. A partir de una investigación cuantitativa dirigida a responsables de restaurantes en Ecuador, se obtuvieron 120 cuestionarios válidos que permitieron estimar un modelo de ecuaciones estructurales a través de la regresión de mínimos cuadrados parciales. Los resultados obtenidos evidencian que las prácticas verdes orientadas a la formación del empleado y la innovación sostenible contribuyen significativamente a la reducción del desperdicio alimentario, que, a su vez, junto a l…
Multiscale Model Selection for High-Frequency Financial Data of a Large Tick Stock by Means of the Jensen–Shannon Metric
2014
Modeling financial time series at different time scales is still an open challenge. The choice of a suitable indicator quantifying the distance between the model and the data is therefore of fundamental importance for selecting models. In this paper, we propose a multiscale model selection method based on the Jensen–Shannon distance in order to select the model that is able to better reproduce the distribution of price changes at different time scales. Specifically, we consider the problem of modeling the ultra high frequency dynamics of an asset with a large tick-to-price ratio. We study the price process at different time scales and compute the Jensen–Shannon distance between the original…
“Your ride has arrived” – Exploring the nexus between subjective well-being, socio-cultural beliefs, COVID-19, and the sharing economy
2021
This study aimed to identify and explain different facets of the sharing economy and to differentiate between micro- and macro-mobility services. We also aimed to examine the correlation between the sharing economy and subjective well-being, cultural beliefs, and COVID-19. An exploratory research technique with face-to-face semi-structured interviews was used to collect data from a sample of 22 rideshare app users in a developing country between January and May 2020 and in July 2020. The data were analyzed using the NVivo 12 application. The major findings suggest that, considering their scope and use, sharing economy technology and services can be divided into four major domains: (1) hospi…
A dynamic analysis of SP 500, FTSE 100 and EURO STOXX 50 indices under different exchange rates.
2018
In this study, we assess the dynamic evolution of short-term correlation, long-term cointe-gration and Error Correction Model (hereafter referred to as ECM)-based long-term Granger causality between each pair of US, UK, and Eurozone stock markets from 1980 to 2015 using the rolling-window technique. A comparative analysis of pairwise dynamic integration and causality of stock markets, measured in common and domestic currency terms, is conducted to evaluate comprehensively how exchange rate fluctuations affect the time-varying integration among the S&P 500, FTSE 100 and EURO STOXX 50 indices. The results obtained show that the dynamic correlation, cointegration and ECM-based long-run Gra…
THE SCOPE OF DUE DILIGENCE IN CROSS-BORDER ACQUISITIONS IN CENTRAL AND EASTERN EUROPE
2015
Cross-border acquisitions play an important role in the corporate strategic development and international expansion. The paper summarizes the results of the dissertation, which intends to establish vital link between research and practice, deeply exploring the risk assessment methods and the scope of due diligence audit in the pre-acquisition phase. The central hypothesis of the comprehensive model stated that thorough due diligence in the pre-acquisition phase is necessary to make successful cross-border acquisition. The empirical evidence has been drawn on data sample of acquisitions made by automotive firms in cross-border acquisitions in the Central and Eastern Europe. The main results …
Segmentation algorithm for non-stationary compound Poisson processes
2010
We introduce an algorithm for the segmentation of a class of regime switching processes. The segmentation algorithm is a non parametric statistical method able to identify the regimes (patches) of a time series. The process is composed of consecutive patches of variable length. In each patch the process is described by a stationary compound Poisson process, i.e. a Poisson process where each count is associated with a fluctuating signal. The parameters of the process are different in each patch and therefore the time series is non-stationary. Our method is a generalization of the algorithm introduced by Bernaola-Galván, et al. [Phys. Rev. Lett. 87, 168105 (2001)]. We show that the new algori…
Consumer Information Systems as Services
2017
Consumer Information Systems (CIS) are a type of information systems that provides services to consumers instead of addressing users in traditional organizational settings, such as Internet based television. Services typically involve a trade-off between achieving high service productivity and quality. The use of service mass customization to successfully address these issues of both productivity and quality in a service context is proposed. We suggest that the development of Consumer Information Systems as Services (CISaS) may achieve such service mass customization. This paper presents a conceptual framework and investigates how it applies to a set of Internet Protocol Television (IPTV) o…
