An analysis of health expenditure on a microdata population basis

The objective of this paper is to analyse the hospitalisation and the pharmaceutical expenditures of a population. To do so, we will use cross-sectional information for the year 2004, referring to the whole population of one of the seventeen autonomous communities that make up the Spanish public health system, namely, Aragón. Given the important proportion of null expenditures, a model that takes into account the censored nature of the data must be specified. In our case, the model we choose is Heckman's (1979) selection model. The results are conclusive. i) Age, being a pensioner and being of Spanish nationality positively influence the generation of both types of expenditure; ii) on the contrary, the distance from the health centre to the hospital affects them negatively; iii) sex notably influences the generation of both types of expenditure, women generating higher level of expenditures; iv), in both cases, significant differences appear associated with the zone to which the user belongs; and v) we have also found that pharmaceutical expenditure depends significantly on the doctor who is prescribing.     

Improving the “Leader–Follower” Relationship: Top Manager or Supervisor? The Ethical Leadership Trickle-Down Effect on Follower Job Response

Since time immemorial, the phenomenon of leadership and its understanding has attracted the attention of the business world because of its important role in human groups. Nevertheless, for years efforts to understand this concept have only been centred on people in leadership roles, thus overlooking an important aspect in its understanding: the necessary moral dimension which is implicit in the relationship between leader and follower. As an illustrative example of the importance of considering good morality in leadership, an empirical study is conducted in which a good performance of the “leader–follower” relationship is reflected when individuals perceive ethical leadership in higher hierarchical managerial levels. To be precise, findings of this study demonstrate that follower job response is improved through an ethics trickle-down partial effect from the Top Manager to the immediate supervisor, and also reveal both key aspects and managerial level on which the practice of ethical leadership should rest upon to have a stronger effect on the follower positive job response. Practical implications of these findings and directions for future research are finally presented.     

An application of health-portals to improve electronic listening

Electronic listening (eListening) is an innovation that potentially provides patients and other users with the right answer in the right place at the right time. Thus, eListening can potentially improve service flexibility, adaptability and quality. The main purpose of this paper is to investigate the extent to which new web-based service delivery channels, which we refer to as health-portals (he-portals), facilitate eListening in the Spanish public healthcare sector. In this paper, we investigate the relative importance and significance of hospital size and three different types of information and communications technologies (Internet, groupware and collective systems) on the use of eListening through an empirical investigation of 300 Spanish public he-portals. Our main conclusion is that the implementation of Internet systems alone does not guarantee the development of effective eListening. In addition, we demonstrate that hospital size does not affect the level of eListening achieved by hospitals.     

Evaluación de la conversión a café orgánico usando la metodología de opciones reales

Since the deregulation of the coffee market in 1989, price crises are proof of the uncertainty and risk around coffee growers’ income, particularly for small producers who, in the case of Mexico, have taken action such as the conversion of their traditional crops into the organic production system which, besides the ecological priority, allows them to get a higher income than from conventional coffee. In this document we model as real investment options (RIO) the possibility of conversion from one system into the other one also including the feasibility of abandoning this strategic decision.     

Role of Retailer Positioning and Product Category on the Relationship Between Store Brand Consumption and Store Loyalty

Recent empirical evidence regarding the relationship between store brand purchase and store loyalty suggests a nonmonotonic relationship (inverted U): positive up to a certain store brand consumption level, after which it becomes negative. To investigate this idea further, this research analyzes the role of (1) the retailer's competitive positioning, and specifically its price positioning, and (2) the product category. On the one hand, the more price oriented the retailer's positioning, the more favorable is the relationship between store brand consumption and store loyalty. The threshold level of store brand purchasing at which the relationship becomes negative occurs later, and this negative relationship is less prominent. On the other hand, the relationship between store brand consumption and store loyalty appears to differ across product categories as a consequence of several factors, including perceived risk. The relationship therefore appears more favorable for risky categories. An empirical study of ten retailers that adopt different price positions corroborates these propositions.     

A multi-process second-order latent growth curve model for subjective well-being

This article proposes a new approach to modelling longitudinal perceptions of subjective well-being (SWB). Several measures have been proposed in the literature to assess SWB and its determinants. Statistical approaches adopted include ordered probit models, fixed and random effects models and cross-lagged structural equation models. The British Household Panel Survey (BHPS) is a longitudinal national representative survey and contains several measures of SWB. Using BHPS data from 2002 to 2005, this article considers two main latent dimensions of life satisfaction: satisfaction with leisure and satisfaction with material issues. The latent trajectories of these two latent life satisfaction dimensions are simultaneously modeled in Mplus, using a multi-process, second-order latent growth curve model. Significant determinants of leisure and material satisfaction growth trajectories include socio-demographic characteristics, number of children in the household, number of hours worked per week, income and perceived health status.     

Exploitation- and exploration-based innovations: The role of knowledge in inter-firm relationships with distributors

Learning capacity is a critical factor for a firm’s innovation and competitiveness. This study explores the issue of how knowledge in inter-firm relationships with distributors influences manufacturers’ exploitation- and exploration-based innovations and performance. The empirical model examines the effect of three different types of knowledge-related issues in inter-firm relationships: (i) the acquisition of substantial knowledge (about products, technology, or markets) from distributors; (ii) the learning about collaborating with each distributor as the relationship evolves; and (iii) the general firm’s knowledge about managing distributors. A model of learning—innovation—performance is developed and tested in a sample of 201 firms in the food and beverages sector. The results reveal that: (i) knowledge about managing distributors promotes continuous learning from them; (ii) learning to collaborate is critical, as it favours knowledge acquisition and both types of innovations (exploitation- and exploration-based); (iii) learning from distributors weakens firms’ tendency to stress one type of innovation strategy over another; and (iv) knowledge in inter-firm relationships with distributors affects performance in a completely mediated way, that is, through innovation. Theoretical and managerial implications of these findings are discussed in the conclusion of the paper.     

Bridging and bonding forms of social capital in a regional strategic network

Research on networks emphasizes the importance of bonds between actors. Social reciprocity strengthens network bonds, which is assumed to have positive effects on business relationships between firms. However, the importance of weak ties is also stressed in network research. An important policy issue is therefore if more attention should be devoted to the creation of bridges to other social groups and loosening bonds between network actors. The difficulty in doing so is described and analyzed in this article focusing on a regional strategic network, which is viewed in three network perspectives. Interview data were collected from all participating managers in a regional strategic network in 2004 and 2010. The findings shed light upon the paradox of using a regional strategic network to counteract over-embeddedness and freeing the involved actors from existing network lock-ins instead of further strengthening such social institutions.
