The growth incidence curve of Ravallion and Chen (2003) is based on the quantile function. Its distribution-free estimator behaves erratically with usual sample sizes leading to problems in the tails. The authors propose a series of parametric models in a Bayesian framework. A first solution consists in modeling the underlying income distribution using simple densities for which the quantile function has a closed analytical form. This solution is extended by considering a mixture model for the underlying income distribution. However, in this case, the quantile function is semi-explicit and has to be evaluated numerically. The last solution consists in adjusting directly a functional form for the Lorenz curve and deriving its first-order derivative to find the corresponding quantile function. The authors compare these models by Monte Carlo simulations and using UK data from the Family Expenditure Survey. The authors devote a particular attention to the analysis of subgroups.

This study aims to examine the formal and metric properties of Gil et al.’s (2000) scale of attitudes toward organic products, which is the most popular scale to measure these attitudes.

The sample consisted of 4,992 household shoppers living in Hong Kong, Germany, Norway, Spain and the UK. The questionnaire was distributed using a third-party consumer panel, and the fieldwork was conducted using computer-assisted Web interviewing. The approach was based on confirmatory factor analysis and measurement of invariance, as well as format analysis using a wording-syntactic and semantic descriptive method.

The scale reflects an attitude-toward-object model approach. Its use has been heavily varied (in terms of wording, item semantics and the attributes to be measured). A two-factor structure that meets the metric conditions (reliability and validity) is found. However, the analysis of invariance shows that the scale behaves differently in different countries.

This scale offers a good starting point for measuring attitudes toward organic products. However, it requires refinement to adapt to consumer evolution and improve its metric validity. Verification of its applicability in cross-national studies is recommended.

To the best of the authors’ knowledge, this is the first study that assesses the format and quantitative characteristics of this scale on a cross-national level. For scholars and companies with international interests, preventing the use of scales with poor properties at the transnational level can improve the design of future studies and save money through a more informed choice of attitudinal scale.

Este estudio examina las propiedades formales y métricas de la escala de actitudes hacia los productos orgánicos de Gil et al. (2000), que es la escala más popular para medir estas actitudes.

La muestra incluye 4.992 compradores principales en hogares de Hong Kong, Alemania, Noruega, España y el Reino Unido. El cuestionario se distribuyó utilizando un panel de consumidores, y el trabajo de campo se llevó a cabo mediante entrevistas online asistidas por ordenador. El enfoque se basó en un análisis factorial confirmatorio y en la invariancia de las medidas, así como en un análisis del formato utilizando un método descriptivo de redacción-sintáctico-semántico.

La escala refleja un enfoque de actitud basada en el objeto. Su uso ha sido muy variado (en redacción, semántica de sus redacciones y los atributos que mide). Se encuentra una estructura de dos factores que cumple con las condiciones métricas (fiabilidad y validez). Sin embargo, el análisis de invariancia muestra que la escala se comporta de manera diferente en distintos países.

Esta escala ofrece un buen punto de partida para medir las actitudes hacia los productos orgánicos, pero requiere un refinamiento para adaptarse a la evolución del consumidor y para mejorar su validez métrica. Se recomienda verificar su aplicabilidad en los estudios internacionales comparados.

Este es el primer estudio que evalúa el formato y las características cuantitativas de esta escala a nivel internacional. Para los académicos y las empresas con intereses internacionales, evitar el uso de escalas con propiedades deficientes a nivel transnacional puede mejorar el diseño de futuros estudios y ahorrar dinero a través de una elección más informada de la escala actitudinal.

A place brand is a public instrument for territorial development that needs a strategic design that is made by the public sector with the support of experts. To ensure that this design has the greatest chances, there should be an alignment between them regarding how the public sector should act when designing the place brand. This study aims to analyze the alignment and polarization among experts regarding this topic and whether experts with different place brand visions show different expectations in the public sector.

A Web survey was conducted using a sample (n = 260) of four types of experts (politicians, scholars, public managers and consultants) in Latin America and Spain.

First, there is high agreement that the public sector should have an active role and an open attitude to establish relationships with the private and voluntary sectors. This favors the dialogue among brand creators and generates a shared vision. Second, there is an elevated alignment with regards to which roles the public sector should play, independently of experts’ place brand visions. Finally, four aspects derived from the four place brand visions are detected that can favor different final approaches regarding the place brand strategic design.

The study has been performed in Latin America and Spain. Other studies in other areas can complete the previous results.

The results show how experts perceive the desirables behaviors from the public sector, which is a missing topic in place brand literature.

We provide a Bayesian inference for a mixture of two Pareto distributions which is then used to approximate the upper tail of a wage distribution. The model is applied to the data from the CPS Outgoing Rotation Group to analyze the recent structure of top wages in the United States from 1992 through 2009. We find an enormous earnings inequality between the very highest wage earners (the “superstars”), and the other high wage earners. These findings are largely in accordance with the alternative explanations combining the model of superstars and the model of tournaments in hierarchical organization structure. The approach can be used to analyze the recent pay gaps among top executives in large firms so as to exhibit the “superstar” effect.

Over the last decades, the development of entrepreneurial activity has allowed greater growth and economic development in Spain. However, within the analysis of Spanish entrepreneurial dynamics, insufficient attention has been paid to a key group: senior entrepreneurs. The fact that the first two decades of the 21st century have been accompanied by the two worst economic crises in remembrance since the Great Depression of the 1930s has had a great impact on the professional careers of the group of senior workers, whose careers have been cut short due to the closure of companies. In this way, the present work delves into the reality of senior entrepreneurs in Spain, analyzing the main characteristics of this group, which is becoming increasingly important in society.

Using microdata from the Spanish National Statistics Institute's Labour Force Survey, the study focuses on reference persons who, being 50 years of age or over and actively working, work as an entrepreneur and have started their activity in the last 12 months. The study covers, in turn, the analysis period of the fourth quarters from 2005 to 2020. In relation to the methodology, the work focuses on the use of binary logistic regression techniques, given that the phenomenon to be studied is binary in nature: entrepreneurship or not.

The main conclusions drawn are the importance of sociodemographic factors such as educational level, age, the profession of the couple as well as the fact of having or not having children. The sector of activity and region are also significant. It is also concluded that senior entrepreneurship in Spain is of a necessary nature, considering the evolution of unemployment and decisions based on pension reform.

The main limitations of the study refer to the lack of socioeconomic information. Thus, it would be interesting to know the link among the sociodemographic characteristics and the economic situation of the professionals, as well as the fact of whether they have started from a previous situation of unemployment or employment.

The obtained conclusions allow progress to be made in the generation of economic policies aimed at the professional reorientation of a group of workers who, due to labor market circumstances, are obliged to end long professional careers and to seek alternatives. In fact, entrepreneurship is a viable professional alternative for these professionals.

Despite the importance of senior professionals in the Spanish economy, more research is needed on their characteristics and needs. Despite important studies such as Socci et al. (2020) or Perez-Encinas et al. (2021), there are not many studies for the Spanish reality. This paper seeks to deepen the understanding of the sociodemographic characteristics of Spanish senior entrepreneurs, based on current public information and considering different stages of the economic cycle.

The purpose of this paper is to propose a framework of green strategies as a combination of energy-efficiency measures and solutions towards environmental impact reduction for improving environmental sustainability at logistics sites. Such measures are examined by discussing the related impacts, motivations and barriers that could influence the measures' adoption. Starting from the framework, directions for future research in this field are outlined.

The proposed framework was developed starting from a systematic literature review (SLR) approach on 60 papers published from 2008 to 2022 in international peer-reviewed journals or conference proceedings.

The framework identifies six main areas of intervention (“green strategies”) towards green warehousing, namely Building, Utilities, Lighting, Material Handling and Automation, Materials and Operational Practices. For each strategy, specific energy-efficiency measures and solutions towards environmental impact reduction are further pinpointed. In most cases, “green-gold” measures emerge as the most appealing, entailing environmental and economic benefits at the same time. Finally, for each measure the relationship with the measures' primary impacts is discussed.

From an academic viewpoint, the framework fills a major gap in the scientific literature since, for the first time, this study elaborates the concept of green warehousing as a result of energy-efficiency measures and solutions towards environmental impact reduction. A classification of the main areas of intervention (“green strategies”) is proposed by adopting a holistic approach. From a managerial perspective, the paper addresses a compelling need of practitioners – e.g. logistics service providers (LSPs), manufacturers and retailers – for practices and solutions towards greener warehousing processes to increase energy efficiency and decrease the environmental impact of the practitioners' logistics facilities. In this sense, the proposed framework can provide valuable support for logistics managers that are about to approach the challenge of turning the managers' warehouses into greener nodes of the managers' supply chains.

This study aims to identify the decision-making process involved in the purchase of organic wine from consumer values to attitudes to behavioural intention towards organic wine via the value–attitude–behaviour (VAB) model. Involvement in wine is also taken into consideration.

The data were collected using a snowball sampling method and a closed-ended questionnaire. A total of 209 responses were analysed. Linear regression and PROCESS Macro on SPSS were used to perform data analysis.

Both biospheric-altruistic values and egoistic values are positively associated with attitudes towards organic wine. Attitude is found to mediate the relationship between biospheric-altruistic/egoistic values and behavioural intention. Egoistic values are found to significantly predict behavioural intention in the organic wine purchase context. Involvement was found to moderate the relationship between egoistic values and attitudinal loyalty.

This study identifies the decision-making hierarchy from consumer values to attitudes to behavioural intention, theoretically confirming the robustness of the VAB model in the organic wine consumption context. It also makes a practical contribution by indicating the marketing emphasis of organic wine and segmenting potential consumers according to their values and levels of wine involvement.

This study seeks to enhance productivity, motivation and well-being of workers by improving decision-making processes. Using inner knowledge management (IKM), this study aims to identify, manage and transform unconscious beliefs and negative emotions that limit decision-making processes.

The methodology used is empirical research, analyzing multiple cases qualitatively and using the T-test statistical model to analyze the hypotheses. The study tests the relation between different limiting beliefs and negative emotions that influence decision-making processes.

This study shows that IKM is positively related to the productivity, motivation and well-being of workers.

The study is limited to workers who are mentally healthy, who work in teams and who seek professional help to achieve their goals.

The results indicate that there is a lot of potential to be explored applying IKM in companies and organizations. Specifically, this study proves that there are several inner knowledge assets that constrain the workers’ potential and therefore affect the efficiency of businesses.

The results have strong implications for how companies and organizations can create great value for themselves and their workers.

To the best of the authors’ knowledge, this is the first data-based study using an IKM model. The importance of this study opens the door to further exploration of the effects on IKM on productivity, motivation and the general well-being of workers.

The purpose of this paper is to examine the influence of consumers’ perceived corporate social responsibility (CSR). The aim is to provide insight into the effect of perceived CSR on purchase intention (short-term effect) and corporate reputation (long-term effect), whilst considering the role of brand image, satisfaction (affective and cognitive) and brand loyalty.

The sample comprised 429 consumers selected using non-probabilistic sampling with age and gender quotas. Confirmatory factor analysis was used to validate the measurement model. Structural equation modelling was used to validate the research hypotheses.

All direct and mediated influences in the model were significant, except for the effects of perceived CSR on affective satisfaction. Thus, the proposed causal chain is valuable to understand how perceptions of CSR influence purchase intention and perceived reputation.

Perception is considered a dual phenomenon (cognitive and affective). It would be advisable to consider both dimensions in the future. The same is true of affective satisfaction.

Direct and mediated relationships that have previously been studied separately are considered together in a single model. This approach provides a better understanding of how perceived CSR influences purchase intention and reputation.

The purpose of this paper is to propose information leadership as a concept for describing the activity of leading information processes in organisations and in the society, and consequently, to distinguish and articulate the influence and consequences of making decisions about the use, organisation and management of information resources and information infrastructures.

To complement the earlier observations of the usefulness of making an analytical distinction between information and knowledge, and management and leadership within information management/knowledge management, this paper posits that it is useful to distinguish information and knowledge leadership as two separate yet inherently connected processes of orchestrating respectively information infrastructures and resources, and the processes of knowing in an organisation.

This paper defines information leadership as the leadership of information resources and infrastructures in contrast to the leadership of social knowledge processes, knowing and organisational learning. The distinction helps to explicate the informational premises of knowledge in organisations, articulate the difference of the infrastructural and social forms of leadership and to be more explicit about the respective consequences of information and information infrastructures and knowledge held and practised within an organisation and on its boundaries.

The concept of information leadership can be used both for describing the activity of leading the development and using information resources and infrastructures in organisations, and for articulating the influence and consequences of making decisions about the use, organisation and management of information resources and information infrastructures.

To the knowledge of the authors, this is the first time information leadership is defined comprehensively in the context of information and knowledge management and specifically in relation to knowledge leadership.
