This paper estimates the effects of friends' health behaviors, smoking and drinking, on own health behaviors for adolescents while controlling for the effects of correlated unobservables between those friends. Specifically, the effect of friends' health behaviors is identified by comparing similar individuals who have the same friendship opportunities because they attend the same school and make similar friendship choices, under the assumption that the friendship choice reveals information about an individual's unobservables. We combine this identification strategy with a cross-cohort, within school design so that the model is identified based on across grade differences in the clustering of health behaviors within specific friendship patterns. Finally, we use the estimated information on correlated unobservables to examine longitudinal data on the on-set of health behaviors, where the opportunity for reverse causality should be minimal. Our estimates for both behavior and on-set are very robust to bias from correlated unobservables.
The PROSPER study is the premier study of adolescent peer networks in the world, with a scope of over 12,000 youth in 28 school districts, and with 8 annual waves of data collection covering grades 6-12. Research output from the PROSPER study has provided extensive new insights in the areas of adolescent development, risky behaviors, and social networks. Through the lens of the PROSPER study, Teen Friendship Networks, Development, and Risky Behavior describes the many ways that adolescent friendship networks channel and facilitate the spread of adolescent substance use, delinquent behaviors, mental health problems, educational success, romantic relationships, and future development. Introductory chapters explain the theories of adolescent development and the elements of peer network science. The chapters of the main part of the book each focus on a domain of adolescent behavior, providing background on the topic and highlighting the contribution of the PROSPER study to understanding the way teen friendships operate to promote initiation or diffusion of the behavior or attribute. With coverage of major themes such as the ways that teens select friends based on particular characteristics or similarity between them, and the ways that friends, once selected, influence each other, as well as discussion of how friendship and network patterns are linked to the uptake and spread of positive prevention messages, Teen Friendship Networks, Development, and Risky Behavior will appeal to researchers and students across several fields.
Appropriate for use in developmental research methods or analysis of change courses, this is the first methods handbook specifically designed to meet the needs of those studying development. Leading developmental methodologists present cutting-edge analytic tools and describe how and when to use them, in accessible, nontechnical language. They also provide valuable guidance for strengthening developmental research with designs that anticipate potential sources of bias. Throughout the chapters, research examples demonstrate the procedures in action and give readers a better understanding of how to match research questions to developmental methods. The companion website (www.guilford.com/laursen-materials) supplies data and program syntax files for many of the chapter examples.
Urban Youth Friendships and Community Practice breaks new ground in identifying and capturing the importance of friendships and the role that community practitioners and scholars can play to enhance them.
Edited by Mahzad Hojjat and Anne Moyer, The Psychology of Friendship provides a comprehensive overview of the research on these important relationships, which represent one of humanity's closest connections. This book provides a wealth of information on both the beneficial and detrimental aspects of this important bond in everyone's lives.
Social Networks and Social Support in Childhood and Adolescence (Prevention and Intervention in Childhood and Adolescence).
This volume is designed to guide the reader through the research on close relationships before, during, and after adolescence. It begins with a section on developmental pathways and processes. The next section is devoted to family relationships during the transitions into adolescence and young adulthood. The final two sections concern peer relationships.
Developments in methodologies, agglomeration, and a range of applied issues have characterized recent advances in regional and urban studies. Volume 5 concentrates on these developments while treating traditional subjects such as housing, the costs and benefits of cities, and policy issues beyond regional inequalities. Contributors make a habit of combining theory and empirics in each chapter, guiding research amid a trend in applied economics towards structural and quasi-experimental approaches. Clearly distinguished from the New Economic Geography covered by Volume 4, these articles feature an international approach that positions recent advances within the discipline of economics and society at large. - Emphasizes advances in applied econometrics and the blurring of "within" and "between" cities - Promotes the integration of theory and empirics in most chapters - Presents new research on housing, especially in macro and international finance contexts
Tobacco consumption continues to be the leading cause of preventable disease and death in the United States. The Food and Drug Administration (FDA) regulates the manufacture, distribution, and marketing of tobacco products - specifically cigarettes, cigarette tobacco, roll-your-own tobacco, and smokeless tobacco - to protect public health and reduce tobacco use in the United States. Given the strong social component inherent to tobacco use onset, cessation, and relapse, and given the heterogeneity of those social interactions, agent-based models have the potential to be an essential tool in assessing the effects of policies to control tobacco. Assessing the Use of Agent-Based Models for Tobacco Regulation describes the complex tobacco environment; discusses the usefulness of agent-based models to inform tobacco policy and regulation; presents an evaluation framework for policy-relevant agent-based models; examines the role and type of data needed to develop agent-based models for tobacco regulation; provides an assessment of the agent-based model developed for FDA; and offers strategies for using agent-based models to inform decision making in the future.
