With firms’ increasing interest in marketing analytics, customer valuation receives more attention than ever. This is clearly reflected in recent advances in customer lifetime value calculation for non-contractual business settings such as grocery retailing. However, due to the novelty of these developments there is little empirical evidence on when which model performs best. To calculate customer lifetime value in non-contractual settings it is essential to statistically model both, how long a customer will stay with the firm as well as the frequency of a customer’s future transactions. The Pareto/NBD model (Schmittlein, Morrison, and Colombo, 1987) was the first model to address both issues and is currently the de facto standard in marketing practice and research. Recently, alternative models have been proposed, such as the BG/NBD model (Fader, Hardie and Lee, 2005), the GGompertz/NBD (Bemmaor and Glady, 2012), and the Normal/NBD model (Jain and Singh, 2013). Besides, some initial work has been done on the inclusion of covariates into these models. However, no empirical comparison of those approaches across multiple real-world scenarios exists. We contribute to the literature on customer lifetime value by providing a structured review of recent modeling approaches for non-contractual business settings. Additionally, we compare the models’ performance by using four different datasets from the grocery retail, luxury goods, travel, and video-on-demand industry. Our findings have strong implications for both, marketing practice and research. Besides giving detailed recommendations on when to use which modeling approach, we also provide practical advices for estimating these models.

In this paper we study the identification of discrete choice models of dynamically optimizing consumers. We first provide additional formal results for existing identification solutions. We then investigate the ‘last in, last out’ (LILO) constraint on consuming from the inventory as a means to identifying the discount factor in these models. We find that the LILO constraint (over-)identifies the discount parameter in the absence of assumptions about consumers’ expectations and show how LILO results in efficient estimates in a parametric, maximum likelihood framework using simulated data. Finally, we report survey based empirical evidence for the relevance of LILO strategies in four different categories.

The Mental Health Continuum-Short Form (MHC-SF) developed by Keyes (2009) is the tool that allows for continuous assessment of subjective well-being (including its three aspects: emotional, psychological, and social), as well as for the categorical diagnosis of the presence of mental health and the absence of mental health (understood as flourishing and languishing). This paper presents the result of the validation and psychometric parameters of the Polish MHC-SF. The participants included 2115 respondents aged 16–81 (55.6% women) from Poland. The findings confirmed the reliability of MHC-SF, external validity, three-dimensional structure of subjective well-being, and supported two-continua model of mental health, where mental health and mental illness are two related but distinguishable dimensions, not at the ends of the same continuum.

Prezentowany artykuł, będący wprowadzeniem do niniejszego numeru Roczników Psychologicznych, poświęconego cechom osobowości i ich pomiarowi, składa się z dwóch części. W pierwszej z nich zostały omówione dwie tradycje badawcze posługujące się taksonomią pięciu cech osobowości: tradycja leksykalna (posługująca się terminem Wielka Piątka) i psychometryczna (posługująca się terminem Pięcioczynnikowy Model Osobowości). Autorzy omawiają podobieństwa i różnice między tymi tradycjami, a także teoretyczne podstawy pojawiających się w ostatnich badaniach innych modeli, takich jak model Wielkiej Szóstki czy Wielkiej Dwójki. W drugiej części artykułu zostały przedstawione wybrane zagadnienia związane z pomiarem cech osobowości (szczegółowo analizowane przez autorów w kilku tekstach wchodzących w skład tego numeru Roczników. Szczególną uwagę zwrócono na różnice między operacjonalizacją pięciu cech w różnych kwestionariuszach, a także na rosnącą popularność krótkich skal do pomiaru cech osobowości. Zaprezentowano też problemy związane z pomiarem cech osobowości i wykorzystywane narzędzia psychometryczne. The article is an introduction to the volume devoted to personality traits and their measurement. It consists of two parts. The first part presents two research traditions that use the taxonomy of five personality traits: the lexical tradition (using the term "Big Five") and the psychometric tradition (using the term "Five-Factor Model of Personality"). Similarities and differences between these traditions are outlined and the basic elements of other models that have appeared in recent studies - such as the Big Six or the Big Two - are introduced in it. The second part of the paper presents selected issues of measurement, discussed in detail in several texts included in the current issue of Annals of Psychology. Special attention is drawn to differences between various questionnaires in the operationalization of the five traits as well as to the growing popularity of short scales for measuring personality traits. The paper also outlines problems involved in the measurement of personality traits and the psychometric instruments used.

The paper is a review of current discussion on the Big Five model and new proposals of personality structure description. The discussion concerns three main claims of the Big Five model: (1) the claim about number of basic traits; (2) the claim about the organization of lower-level traits and (2) the claim about relations between the basic traits. Critique of each claim has led to a counterproposal that describes the personality structure in a different way. Critique of the first assumption is supported by the proposal of increasing to six number of basic traits in the HEXACO model (Ashton, Lee, 2001, 2007). Critique of the second assumption is supported by the proposals of different lower-traits organization. The Abridged Big Five Dimensional Circumplex (Hofstee, De Raad, Goldberg, 1992; Goldberg, 1999) and the model of 10 aspects located between the basic five traits and their facets (DeYoung, Quilty, Peterson, 2007) there are reviewed in the paper. The critique of the third assumption argues that the five traits are not orthogonal and the systematical relations between them can be explained by two higher-order factors (Digman, 1997; DeYoung, Peterson, Higgins, 2002) or even one General Factor of Personality (Musek, 2007; Rushton, Irving, 2011).
