A 2020 perspective on “Spreading the word : how customer experience in a traditional retail setting influences consumer traditional and electronic word-of-mouth intention”
Siqueira Junior, José Ribamar; Peña García, Nathalie; ter Horst, Enrique; Molina, Germán (Elsevier BV, 2020-01-28)The convergence of the brick and mortar and online worlds is now more prominent than ever. It is becoming increasingly difficult to operate exclusively in one of these two environments. While physical stores provide retailers ... -
Application of the method of maximum entropy in the mean to classification problems
Gzyl, Henryk; ter Horst, Enrique; Molina, Germán (Elsevier BV, 2015-11-01)In this note we propose an application of the method of maximum entropy in the mean to solve a class of inverse problems comprising classification problems and feasibility problems appearing in optimization. Such problems ... -
A Bayesian Beta Markov Random Field calibration of the term structure of implied risk neutral densities
Casarin, Roberto; Leisen, Fabrizio; Molina, Germán; ter Horst, Enrique (International Society for Bayesian Analysis, 2015-12)We build on the derivative pricing calibration literature, and propose a more general calibration model for implied risk neutral densities. Our model allows for the joint calibration of a set of densities at different ... -
Bayesian inference for a structural credit risk model with stochastic volatility and stochastic interest rates
Rodríguez, Abel; ter Horst, Enrique; Malone, Samuel W. (Oxford University Press, 2015)We develop a novel structural credit risk model that extends the original Merton model by allowing for stochastic interest rates and stochastic volatility. The model is estimated using Bayesian methods implemented via a ... -
Branding in the eye of the storm : the impact of brand ethical behavior on brand commitment during the COVID-19 crisis in a South American country
Siqueira Junior, José Ribamar; ter Horst, Enrique; Molina, Germán; Gunn, Laura H.; Reinoso Carvalho, Felipe; Sezen, Burcu; Peña García, Nathalie (Palgrave Macmillan Ltd., 2023-03)The purpose of this study is to determine how consumer perceptions of brand ethical behavior can affect their commitment to brands during turbulent times. A study of the effects of perceived ethical behavior of brands in ... -
Comment on article by Windle and Carvalho
ter Horst, Enrique; Molina, Germán (International Society for Bayesian Analysis, 2014)The article by Windle and Carvalho introduces a fast update procedure for covariance matrices through the introduction of higher frequency sources of information for the underlying process, demonstrated with a financial ... -
Customer behavior in electronic commerce : a bayesian approach
Dakduk, Silvana; ter Horst, Enrique; Santalla-Banderali, Zuleima; Molina, Germán; Malavé, José (MDPI AG, 2017-05)Online shopping has increasingly replaced traditional retail shopping, as a large number of consumers have adopted it on a global scale. However, while it is well established in developed countries, e-commerce is still at ... -
Imagen país de Colombia desde la perspectiva extranjera
Echeverri Cañas, Lina María; ter Horst, Enrique; Parra Sánchez, José Hernán (Consejo Superior de Investigaciones Científicas (CSIC). Departamento de Publicaciones, 2015)Colombia es un país con un posicionamiento histórico negativo en mercados internacionales. Si bien los gobiernos y los prescriptores han dedicado esfuerzos por mejorarla, la percepción del extranjero se mantiene polarizada, ... -
Inferring probability densities from expert opinion
Gzyl, Henryk; ter Horst, Enrique; Molina, Germán (Elsevier Inc., 2017-03)When experts are asked to assess a situation, they often express their opinions providing estimates of the probability of observing the occurrence of a random variable in given intervals, sometimes up to a range of values, ... -
Numerical determination of hitting time distributions from their Laplace transforms : simple cases
Gzyl, Henryk; ter Horst, Enrique (Elsevier BV, 2014-09-15)An important problem in probabilistic modeling consists of the determination of the distribution function of a positive random variable, in particular a hitting time, from its Laplace transform. In this note we use two ... -
A relationship between the ordinary maximum entropy method and the method of maximum entropy in the mean
Gzyl, Henryk; ter Horst, Enrique (MDPI AG, 2014-02-24)There are two entropy-based methods to deal with linear inverse problems, which we shall call the ordinary method of maximum entropy (OME) and the method of maximum entropy in the mean (MEM). Not only does MEM use OME as ... -
The role of brand commitment in the retail sector : the relation with open innovation
Siqueira Junior, José Ribamar; Peña García, Nathalie; ter Horst, Enrique; Molina, Germán; Villamil, Monica (MDPI AG, 2021-06-11)Firm–employee relationships are a prerequisite for customer–firm relationships and, consequently, to organizational success. The development of such relationships can be particularly challenging for retailers because of ... -
A spectral measure estimation problem in rheology
Gzyl, Henryk; ter Horst, Enrique; Molina, Germán (Elsevier BV, 2015-09-15)In this paper we consider an inverse problem appearing in rheology, consisting of determining a spectral measure over the set of relaxation times, that yields an observed collection of loss and storage moduli. Mathematically ... -
Spreading the word : how customer experience in a traditional retail setting influences consumer traditional and electronic word-of-mouth Intention
Siqueira Junior, José Ribamar; Peña García, Nathalie; ter Horst, Enrique; Molina, Germán (Elsevier BV, 2019-06-10)The study of customer experience has gained substantial importance in the consumer behavior field because of how it impacts the development of long-term relationships with customers. The next frontier of customer experience ... -
