Available in PDF, EPUB and Kindle. Book excerpt: Most social science theories attempt to explain the ways in which social interactions affect human behavior. Inferences therefore depend upon a researchers' ability to measure and characterize these interactions. In this dissertation, we highlight several inferential challenges in measuring social interactions and show how geographical data can be used to address them. One such challenge is posed by exposure to various treatments; many treatment variables of interest are difficult to measure in a coherent and unified way. Chapter 2 illustrates the way in which public records can be used to overcome this challenge. Another challenge is post-treatment sorting. Once social conflict begins, one of the first things that groups do is segregate themselves into smaller sub-groups. Chapter 3 introduces a new instrumental variable to correct for this bias in census data. Lastly, Chapter 4 introduces a novel method for estimating where social media users spend time during their day. These findings and novel methods will contribute to social scientists' ability to study contextual effects on behavior.

Book excerpt: The aim of this thesis is to investigate identification of peer effects and their application on a large set of outcomes, going from school attendance to obesity. The relevance of this research relies on three main points: 1) it allows better measurrement of effects stemming from social interactions, thus providing some answer to the numerous econometric issues that make the study of peer effects a lot challenging; 2) it improves our comprehension of negative social phenomena, including the incidence of school dropouts and obesity; 3) it proposes better public policies aiming at fighting against such phenomena by exploiting social network effects that contribute to amplify them. The different objectives of this thesis are investigated in three different chapters. The first chapter proposes a new strategy for estimating the influence of the social network on individual decisions in a network context using randomized experiments. It combinates the structural social network model developed by Bramoullé et al. [2009] and randomized experiments. New identification conditions that mostly require balance in the characteristics of friends between treatment and control groups are provided. The model is estimated and validated on experimental data collected for the evaluation of a scholarship program in Colombia. By design, randomization is at the student-level. Friendship data reveals that treated and untreated students interact together. Besides providing evidence of peer effects in schooling, the chapter concludes that ignoring peer effects would have led to an overestimation of the program actual impact. The aim of the second chapter is to propose a model that accounts for heterogeneity in peer effects between individual categories in a network setting. Identification conditions of a network-based interactions model that generalizes the one proposed by Bramoullé et al. [2009] are derived, and heterogeneity of peer effects is allowed within and between categories of individuals. Using the Add-Health dataset, the study explores heterogeneity in adolescents weight using both gender and racial categorizations. The results show that the positive endogenous effect found using the homogeneous model is actually heterogeneous when considering both gender and racial categorizations, as for example, females seem to be more influenced by their female friends than by their male friends. While the first two chapters consider friendship networks in an attempt to identify the effects that result from social interactions, the third chapter considers the course-overlaps network. The model is local agregate and has the feature, unlike other studies of peer effects, that the interaction matrix accounts for the extensive and intensive margins. Interactions of this type are better to design school policies. The chapter then proceeds to estimation of peer effects in overall GPA and GPAs in both mathematics and science courses using the Add Heakth and AHAA datasets. The results reveal the presence of positive and significant social interaction effects using both 2SLS and GMM estimation techniques.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses on the social interaction with economic perspectives. This first essay tests peer effects in the workplace with piece-rate compensation. Reference groups are defined as the geographical peers in undirected networks. A series of spatial econometric models are employed to investigate the social effects. We identify and present evidence for endogenous effects (production) while find no evidence for exogenous effects (characteristics). We also find that the heterogeneity of endogenous effects depends on workers and their peers' characteristics, which is defined as conditional endogenous effects in this paper. Our results suggest that rearranging workers' seats according to their personal characteristics could lead to changes in overall productivity. From a field experiment design, the second essay studies the relation between social distance and training outcomes. We test our hypothesis through two measures: the tips shared with trainees by trainers, and the exist test results of trainees. We find that trainers share more tips to socially closer trainees, and the communications between trainers and trainees have a significant indirect effects on the number of tips shared. The productivity of trainees are also higher when they are socially closer to their trainers. The third essay discusses the identification problem in social peers effect studies. By considering the canonical linear in means model with the rank condition in simultaneous equations model, it suggests that the group structures determines the identifiablity of the desired social effects estimates. Transitive networks are not identified unless there are more information contained in the between group structures. Modifications to the conventional model are also suggested with respect to the recovery of transitive networks and potentially incomplete networks.

Book excerpt: This dissertation is composed of a literature review, Chapter 1, an in-depth analysis of data used in the dissertation, Chapter 2, and three main essays, Chapters 3-5, on relative concerns, social interactions and unintended consequences. To uncover the nature of social interactions, Chapter 3 studies how rural residents form social networks, and what explains the recent gift spending escalation. Chapter 4 focuses on a typical market that carries significant social stigma - paid blood plasma donation in China. I explore the role of peer interactions in the networks. Building upon it, Chapter 5 evaluates how in utero exposures to frequent and costly social events for the impoverished families impacts early child nutrients intake and health status. Chapter 1 This chapter reviews the recent literature on inequality and income distribution in rural China utilizing panel datasets. On the basis of the review, this chapter identifies new research areas with existing panel datasets and my new household panel dataset, i.e., the IFPRI-CAAS, which could shape future research. Chapter 2 The tradition of keeping written gift record in many Asian countries offers researchers an old-fashioned but underutilized means of data collection for development and social network study. This chapter documents a long-term spontaneous household gift record I collected from the field. I discuss the data collection and network structure, highlighting its unique features for studies at household and dyadic link level. Chapter 3 The growth rate of gift and festival spending in some developing countries has been much higher than that of consumption and income. I test three competing explanations of the phenomenon-peer effect, status concern, and risk pooling-based on the IFPRI-CAAS and the gift network data. I find that gift-giving behavior is largely influenced by peers in reference groups. Status concern is another key motive for keeping up with the Joneses in extending gifts. In contrast, risk pooling does not seem to be a key driver of the observed gift-giving patterns. I also show that large windfall income triggers the escalation of competitive gift-giving behavior. Chapter 4 Despite the resultant disutility, people are still engaged in behavior carrying social stigma. Empirical studies on stigma behavior are rare, largely due to the formidable challenges of collecting data on stigmatized goods and services. Combining the IFPRI-CAAS and the gift network data, I examine frequent blood sales, widely regarded as a stigmatized behavior and the driving force of public health crises. Using a novel spatial identification strategy, I find social interactions with heterogeneous intensities affect plasma sales decisions. Peer effects are directional and work through preference interactions that reduce stigma. Families with unmarried son are more likely to sell plasma to offset costs of getting married in a tight marriage market, such as a bigger house, a higher bride price and a more lavish wedding banquet. Chapter 5 Participating in and presenting gifts at funerals, weddings, and other ceremonies held by fellow villagers have been regarded as social norms. However, it is more burdensome for the poor to take part in these social occasions than the rich. Because the poor often lack the necessary resources, they are forced to cut back on basic consumption, such as food, in order to afford a gift to attend the social festivals. Using the IFPRI-CAAS and the gift dataset, this chapter shows that children born to mothers in poor families who are exposed to a greater number of ceremonies during their pregnancies are more likely to display a lasting detrimental health impact.

Book excerpt: These three essays by the independent German Marxist Karl Korsch offer expositions, often in polemical form, of basic Marxist ideas. Since they cover both sociology and economics, they are excellent guides for the student on the most introductory, though not the most elementary, level. The first essay, "Leading Principles of Marxism," takes up Marxism on the plane of sociology and deals with the relation of Marxism to Comte and positivism, and to bourgeois sociology in general. The second, his introduction to the 1932 German edition of Capital, consists of an assessment of the work in human thought and an important reader's guide to Volume I. The third, "Why I Am a Marxist," is a polemic against various distortions in Marxism and an affirmation of the revolutionary, as against the academic, character of Marxism.

Download or read book Three Essays on Social Media Use and Information Sharing Behavior written by Sarbottam Bhagat and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Social media platforms create rich social structures, expand users' boundaries of social networks and revolutionize traditional forms of communications, social interactions and social relationships. These platforms not only facilitate the creation and sharing of news and information, but they also drive various kinds of businesses models, processes and operations, knowledge sharing, marketing strategies for brand management and socio-political discourses essential for healthy and democratic functions. As such, social media has greater implications on organizations and society brought about by individuals' social media usage patterns, and therefore, calls for further investigations. The main objective of this dissertation is to explore and offer insights into such social media usage and information sharing behaviors via data driven examination of various theories. This dissertation involves three studies that focus on factors that explain individuals' three different social media usage behaviors. Essay 1 investigates individuals' perceived importance of online affiliation, self-esteem, self-regulation and risk-benefit structure as antecedents of users' geo-tagging behavior on social media. Essay 2 examines the role of online news quality, source credibility, individuals' perception towards online civic engagement, attitude towards news sharing and social influences to understand users' news sharing behavior on social media platforms. Essay 3 seeks to examine the individuals' information verification behavior on social media through the lens of individuals' fake news awareness, perceived cost of information verification, trust in social media and truth-seeking.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation consists of three self-contained essays on the economics of social interactions. The first chapter is coauthored with Lorenzo Verstraeten. Knowing that Individuals interact with their peers, we study how a social planner can intervene, changing these interactions, in order to achieve a particular objective. When the objective is welfare maximization, we describe the interventions for games of strategic complements and strategic substitutes. We show that, for strategic complements, the planner uses resources to target central players; while she divides individuals into separated communities in the case of strategic substitutes. We study which connections she targets in order to achieve these goals. The second chapter is coauthored with Lorenzo Verstraeten and analyzes a model of contagion on social network. We ask how a social planner should intervene to prevent contagion. We characterize the optimal intervention and the cost associated. We discuss the intuition behind the choice of the planner and we provide comparative static on the cost of intervention for different type of network. In the third chapter I develop a theoretical study about groups relationship and ask whether intragroup cooperation crowd-out intergroup cooperation. I consider a gift-giving game where cooperation endogenously arises, within and across groups. Cooperation is sustained through peer punishment with the help of a group specific monitoring technology. I specify under which conditions cooperation crowding-out occur. I identify two classes of equilibrium: a Sorting equilibrium where guilty players prefer to be matched outside their group due to a less efficient Out-Group monitoring technology, and a Non Sorting equilibrium where the higher level of In-Group cooperation makes it more attractive for everybody. I then compare their welfare properties and draw conclusions on optimal punishment levels.
