Media and Social Capital

Abstract

We survey the empirical literature in economics on the impact of media technologies on social capital. Guided by a simple model of information and collective action, we cover a range of different outcomes related to social capital—from social and political participation to interpersonal trust—in its benign and destructive manifestations. The impact of media technologies hinges on their content (information versus entertainment), their effectiveness in fostering coordination, and the networks they create as well as on individual characteristics and media consumption choices. Expected final online publication date for the Annual Review of Economics, Volume 14 is August 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.

Research on the Influence of DNN-Based Cross-Media Data Analysis on College Students’ New Media Literacy

“…e media is the medium of dissemination of information [1][2][3]. It refers to the tools, channels, carriers, intermediaries, or technical means that people use to transmit and obtain information, as well as the tools and means to transmit text, voice, and other information.…”

“…ere are still many college students who spread unverified information on the Internet, and even some students directly forward and spread the information without further verification and confirmation of the source and authenticity of the new media information. g [1] � linear g [2] � linear g [3] � linear g [4] � linear D g � Ea(alpha) # define the activation function hierarchically. d g [1] � dz_linear d g [2] � dz_linear d g [3] � dz_linear d g [4] � dz_linear Loss � L2 # Define the cost function DA_loss � dAL2 # define cost derivatives ALGORITHM 1: Pseudocode of the optimization model.…”

Do social media undermine social cohesion? A critical review

“…Similarly, Campante et al. (2022) find that the correlation between Internet penetration and social capital (measured in terms of group membership) was weaker after Facebook became available in a country than before Facebook became available.…”

“…Overall, however, observational studies allow documenting how communication networks create the basic architecture underlying dynamics of political engagement and conflict. This is clearly an advance compared to the aggregate measures of social capital gathered with survey instruments (e.g., Campante et al, 2022). Survey measures can only offer speculative accounts of why networks (and different types of ties) are of theoretical relevance.…”
