Social networks effects on outcomes of government programs: a systematic review

ABSTRACT The adoption of public policies to reduce inequality in Brazil has grown significantly over the last few years, as a result of a social welfare agenda. In an increasingly connected world, social interactions must be taken into account in policy making. This study aims to systematically investigate and map the studies in the area of economics that consider the role of networks in the results of social programs and income transfer. The systematic review method shows the state of the art in the literature regarding the employability of social networks within the scope of public policies, highlighting the main estimation methods, network structures, the most active authors in the area, as well as the open gaps and motivations for further research.摘要 近年来，受社会福利议程驱动，巴西为缩小不平等差距而推行的公共政策显著增多。在互联互通程度不断加深的时代背景下，政策制定必须将社会互动纳入考量范畴。本研究旨在系统性调研并梳理经济学领域中探讨社会网络对社会项目与收入转移项目实施成效影响的相关文献，绘制该领域的研究图谱。本研究运用系统综述方法，呈现公共政策框架下社会网络应用相关研究的前沿进展，重点梳理了主流估计方法、网络结构类型、该领域的高产核心作者，以及尚存的研究空白与后续研究的潜在方向。
