The inclusion of the elderly in the digital era could positively impact their social and economic welfare. However, their level of Internet use is relatively low in Spain compared to other sectors of the population. The present study aims to explain the Internet use in this segment, capturing the heterogeneity across gender in the technology acceptance model (TAM). A sample of 492 individuals over 50 years old has been analyzed using the multigroup approach of structural equations models. The results show that although TAM is suitable for studying the phenomenon, it is necessary to consider how the gender gap in the Internet use development is real for seniors. Contrary to previous results that pointed to a greater importance of the ease of use for women than men among Internet users, male elders seem to perceive more usefulness due to higher levels of ease of use than woman. This ease of use is also better explained by the level of enjoyment for males. All these results point to unique gender differences for older adults in their Internet use.

Purpose: The purpose of this paper is to analyse which factors impact firms' perceived performance in mobile commerce (m-commerce). Introducing the perspective of firms, the paper advances the literature of m-commerce adoption that mainly focuses on the consumer standpoint. Design/methodology/approach: The authors complement the technology-organization-environment (TOE) framework by adding customer value for the firm and the relationship marketing and fit-viability approaches. Using a sample of 125 Spanish firms, structural equations models are used to validate measures and test the proposed hypothesis. Research limitations/implications: The main limitation of this work is the sample size. New studies using larger and more heterogeneous samples in terms of size could consolidate the results achieved in this work, that must be understood as a first step in the analysis of firm m-commerce adoption. Findings: Findings show that the perception of performance by firms engaging in m-commerce depends on the extent to which firms' activity fits mobile business, technological competence and customer value for the firm. Practical implications: Content providers, operators or payment platforms may find in the paper arguments to favour the incorporation of clients to this new channel. Originality/value: This is one of the few papers adopting the perspective of firms, since most of the literature approaches the matter from the consumer standpoint.

The technology adoption of mobile commerce has frequently been studied by considering the extended technology acceptance model (TAM). However, the role of the perceived drivers and impediments affecting potential mobile shoppers' acceptance has been scarcely analyzed. This article highlights: (1) the typology of potential m-shoppers described by their reasons for, and perceived impediments to, mobile shopping and (2) the possible differences in the extended TAM in the resulting categories. In order to do so, we advance a single hypothesis about moderation of the m-shopper type on the relationships presented in the extended TAM. The study was conducted in Spain, a country with significant current and forecasted use of mobile shopping. Data from 476 Spanish mobile phone users were analyzed. The use of latent class cluster allowed us to identify three types of mobile shoppers that show different profiles based on their perception about drivers and impediments. Differences in the extended TAM relations across the clusters were identified using the multigroup approach of structural equation models. The results show support for the moderation effect, providing valuable information for practitioners to understand how consumers develop mobile shopping intentions, which is necessary to implement effective marketing strategies.

Firms are involved in supply chains to achieve operative efficiency, develop strategic advantages, and generate financial profits. However, there is limited evidence regarding how governance mechanisms influence the generation of value from collaboration. Furthermore, how a particular buyer or supplier position provides benefits to partners is unclear. In this paper, we examine the roles of management control information as both a governance mechanism and a source of dynamic capabilities, and its interaction with relational variables to create and capture value following a demand-side perspective. Two separate studies are developed using multigroup structural equation modelling, which analyse buyer and supplier positions played by the firm as a complex supply chain node. The results demonstrate that the characteristics of information sharing have different impacts on value, depending on the role played in the relationship. Although timely information sharing appears to be the key source of operative and financial value in downstream relationships, disaggregated information sharing generates additional strategic advantages in upstream relationships. The presence of different control-trust frameworks mediates the process of value generation, leading to different managerial and theoretical implications.
