The Coasean analysis of lighthouse financing: myths and realities

In ‘The Lighthouse in Economics’ (Coase, R. H. Journalof Law and Economics, vol. 17, no. 2, 357–76, 1974), Coasereached the conclusion that in England there existed a relativelyefficient privately financed lighthouse system, which wouldrefute economists' traditional statements concerning the productionof public goods. The purpose of this paper is to challenge hisconclusion. We first show that, from a methodological and theoreticalperspective, ‘The Lighthouse’ is consistent with‘The Problem of Social Cost’ (Coase, R. H. Journalof Law and Economics, vol. 3, 1–44, 1960). Then, applyingCoase's own method (historical case studies), we attempt tore-examine the respective roles and efficiencies of privateinitiative and government.     

Peer network position and shopping behavior among adolescents

Prior research on consumer group behavior has overlooked the importance of peer group structure and the social position of its members in marketing action, especially among adolescents. This study draws on social network theoretical frame to explore the relationship between adolescents’ structural position in peer networks and the decision to shop with friends. Based on a survey of 1037 adolescents, the study suggests that adolescents’ social positions within a peer network affect the frequency of shopping with friends, although gender moderates the relationship. The findings provide practical guidelines for retailers and other managers who target adolescent consumers.     

Land‐use change trajectories up to 2050: insights from a global agro‐economic model comparison

Changes in agricultural land use have important implications for environmental services. Previous studies of agricultural land‐use futures have been published indicating large uncertainty due to different model assumptions and methodologies. In this article we present a first comprehensive comparison of global agro‐economic models that have harmonized drivers of population, GDP, and biophysical yields. The comparison allows us to ask two research questions: (1) How much cropland will be used under different socioeconomic and climate change scenarios? (2) How can differences in model results be explained? The comparison includes four partial and six general equilibrium models that differ in how they model land supply and amount of potentially available land. We analyze results of two different socioeconomic scenarios and three climate scenarios (one with constant climate). Most models (7 out of 10) project an increase of cropland of 10–25% by 2050 compared to 2005 (under constant climate), but one model projects a decrease. Pasture land expands in some models, which increase the treat on natural vegetation further. Across all models most of the cropland expansion takes place in South America and sub‐Saharan Africa. In general, the strongest differences in model results are related to differences in the costs of land expansion, the endogenous productivity responses, and the assumptions about potential cropland.     

War Legacies,Welfare and Livelihoods in Rural Areas: The Case of Kosovo

This article examines the effects of war on livelihood choices and welfare outcomes of rural households in Kosovo using the 2000 Kosovo Living Standards Measurement Survey. We analyse the extent of the legacy of war on livelihood activities and welfare. We first identify livelihood portfolio clusters of households pursuing similar combinations of activities. These clusters are comparable to those described in more qualitative studies in the immediate post‐conflict period. We then examine the determinants of livelihood portfolio choice and the consequences of these for welfare outcomes. Our results provide evidence of a relationship between a household’s experience of war and livelihood choice. We also identify significant selection effects on welfare for three out of four livelihood clusters, highlighting the fact that selecting into a specific livelihood portfolio changes welfare relative to expected levels. Our results show that war not only affects livelihood choices but also changes the returns to these activities.     

Adolescent consumption autonomy: A cross-cultural examination

Adolescents are an important market segment globally not only for their spending power as adolescents but also for their future spending power as adults. One variable that impacts current and future spending power is the degree to which adolescents are autonomous consumers. This study reports on depth interviews conducted with adolescent girls in France and the United States for the purpose of identifying dimensions of adolescent consumption autonomy based on adolescents' perceptions. Four dimensions of adolescent consumption autonomy are identified, including attitudinal, emotional, functional and financial. Similarities and differences between the two cultures are discussed, and implications for marketing and future research are identified.     

Augmented reality in marketing: Conceptualization and systematic review

This systematic review of the literature focuses on the use of AR and its impacts in the marketing area. It provides a multidisciplinary, up-to-date synthesis of the literature and an exhaustive classification of AR. Through the use of the SPAR-4-SLR protocol, 148 articles were selected for analysis. The study has three main objectives. First, it reports the key characteristics (distribution by year, publication outlets, etc.), theoretical models, and methodologies used in this research domain. Second, it suggests a classification of the types of AR according to their triggers and the object of the augmentation (self vs. external). Third, it proposes a framework that presents (1) the AR features and attributes and the AR use experience; (2) the cognitive, affective, and social mediators; and (3) the outcomes of these experiences. Key moderators (types of AR, types of products, individual characteristics, etc.) are also discussed. Using the TCCM framework (theories, context, characteristics, and methodologies), this study offers several future research avenues and highlights the importance of considering the effects of the different types of AR. Finally, it offers pointers for managers on how to develop efficient AR solutions and how these can be used to reduce a company's carbon footprint.
