How Big Is the Media Multiplier? Evidence from Dyadic News Data

The Review of Economics and Statistics 2026 108(3), 696-711 open access
Abstract This paper estimates the size of the media multiplier, an easily generalizable model-based measure of how far media coverage magnifies the economic response to shocks. We combine monthly aggregated and anonymized credit card activity data from 114 card-issuing countries in 5 destination countries with a large corpus of news coverage in issuing countries reporting on violent events in the destinations. To define and quantify the media multiplier, we estimate a model in which latent beliefs, shaped by either events or news coverage, drive card activity. According to the model, media coverage can more than triple the economic impact of an event. We document, through our model, that this effect is highly heterogeneous and depends on the broader media representation of countries in each other’s news. We speculate about the role of the media in driving international travel patterns.

Growth Experiences and Trust in Government

Quarterly Journal of Economics 2026 141(2), 1761-1822 open access
Abstract This article explores the relationship between economic growth and trust in government using variation in GDP growth experienced over a lifetime since birth. We assemble a newly harmonized global data set across 11 major opinion surveys, comprising 3.3 million respondents in 166 countries since 1990. Exploiting cohort-level variation, we find that people who have experienced higher GDP growth are more prone to trust their governments, with larger effects found in democracies. Higher-growth experiences are also associated with improved perceptions of government performance and living standards. We find no similar channel between growth experience and interpersonal trust. Second, more recent growth experiences appear to matter most for trust in government, with no detectable effect of growth experienced during one’s formative years, closer to birth, or before birth. Third, we find evidence of a “trust paradox” whereby average trust in government is lower in democracies than in autocracies. Our results are robust to a range of falsification exercises, robustness checks, and single-country evidence using the American National Election Studies and the Swiss Household Panel.
