Previous studies on the impact of technology on performance (usefulness) have looked at the Information System (IS) in its role as supplier of information (informating role) and thus they have studied the influence of information quality and system quality on usefulness. However, an IS also has a role in the automation of tasks (automating role), which these studies do not take into account. Accordingly, this paper proposes a factor model that (1) includes explicitly both roles; (2) considers that informating and automating roles mediate the relation between these technological factors (information quality and system quality) and usefulness and (3) includes a system’s level of intervention (i.e. the degree to which technology participates in carrying out the tasks) as an additional factor that determines usefulness. Using a questionnaire, data were gathered on 229 Enterprise Resource Planning system users from different organisations and functional areas and structural equations model was used for analysis. Results show that information quality explains usefulness through both roles. System’s level of intervention explains usefulness through the automating role and system quality explains usefulness through the informating role. The factors’ differentiated effects through each role may help managers to establish more effective criteria and priorities in the various stages of an IS’s life cycle. © 2016 Informa UK Limited, trading as Taylor & Francis Group Source


The analysis of organic-product consumer behavior deals primarily with preferences. There is a need to better under-stand the predictors that determine consumer choices when purchasing organic products. Metropolitan Lima was chosen as the study location. The structured questionnaire involved interviews with 547 organic consumers of the metropolitan area of Lima, Peru. A principal component analysis and a cluster analysis were used to assess the underlying opinions of consumers of organic products. The results revealed that deci-sions to purchase organic products in the future were mainly influenced by factors such as health and quality perceptions. Moreover, profiling the clusters as naturalites, drifters (mid-level) and LOHAS (core level) confirmed the results. The link between health and environment, among other benefits, should be strengthened through communication strategies to increase interest from consumers. © 2015, Universidad Nacional de Colombia 1.

The benefits of automation lead to increase levels of technology intervention. However, automation can have negative effects, such as reducing employee knowledge (deskilling). Other authors claim that automation may also raise knowledge (up-skilling). This study analyzes the effect of automation on an employee's knowledge to determine the presence of deskilling - if the knowledge of the task decreases-, up-skilling - if the knowledge of information system increases- or reskilling (a simultaneous effect of decreasing the knowledge of the task and increasing the knowledge of the information system). By using a survey, we gathered data from 125 users and used partial least squares for the analysis. The results show that if the automation levels vary, presence of reskilling is evident in an individual. The design of information systems should take into consideration automation will finally result in reskilling, simultaneously impairing knowledge of the task but increasing knowledge of the information system.

Lead poisoning of Callao's population is the most severe externality port operations cause in Peru. The problem could have been tackled in 2009, after the government issued a decree regulating how mineral ore was to be handled at Peruvian ports. However, the port regulator's inability to follow the criteria contained in their own regulations led the procedure of selecting the providers of the service to continuous delays, and finally, to a complete stop. As a consequence, Callao's population will continue to be affected by this externality until 2013. The problem the regulator could not solve was to determine whether the market for "mineral ore stevedore services" at Callao Port was monopolistic or competitive. This article re-examines the case and concludes that the market for the service has natural monopoly characteristics. Therefore, the regulator should have ordered the call of an auction to select the least expensive provider and thus spare the population from four more years of lead poisoning. © 2012 Copyright Taylor and Francis Group, LLC.

This paper models the diffusion of mobile telephone subscriptions in Peru. Peru's mobile telephone diffusion has occurred in a concentrated market with relatively high prices and as such it features consumer behaviors such as call management, multiple subscriptions and handset sharing. The study uses two growth models, the Gompertz and the Logistic, compared in terms of fit and forecasting performance using the R2, RMSE and MAPE statistics. The empirical results indicate that the Gompertz model is the most appropriate. Principal Component Analysis, a technique that reduces the arbitrary nature of variable selection, found the determinants of diffusion to be Market concentration, Population, Regulated interconnection tariffs and GDP per capita. The Gompertz model's 5-year forecast of subscriptions predicts a further 11.72 million subscribers, which was validated through the use of linear and nonlinear regressions and 95 percent confidence limits. The study is relevant to Peru's telecommunications industry due to a recent policy focus on mobile business and a new market entrant. © 2013 Elsevier Ltd. Source
