Media coverage and pandemic behavior: Evidence from Sweden

Area of Science:

• Public Health Communication
• Behavioral Economics
• Media Studies

Background:

• Understanding how media influences public behavior during health crises is crucial.
• Sweden's unique approach without lockdowns provides a distinct case study for media impact.
• The Covid-19 pandemic presented an unprecedented challenge for public health messaging.

Purpose of the Study:

• To investigate the causal relationship between media coverage and individual behavior during the Covid-19 pandemic.
• To identify characteristics of media coverage that amplify or diminish behavioral effects.
• To assess the role of local relevance, visibility, and factual reporting in shaping public responses.

Main Methods:

• Analysis of a unique dataset comprising 200,000 Swedish newspaper articles on Covid-19.
• Utilized two distinct identification strategies to establish causal links.
• Correlated media content with changes in mobility data (visits to workplaces, retail, recreation, and residential areas).

Main Results:

• Covid-19 media mentions significantly decreased visits to workplaces and retail/recreation areas.
• Increased mentions of Covid-19 correlated with longer durations spent in residential locations.
• Behavioral effects were amplified by locally relevant, highly visible, and factual news stories.

Conclusions:

• Media coverage has a demonstrable causal effect on public behavior during health crises.
• The framing and characteristics of news content (e.g., source, advice) significantly modulate behavioral impact.
• Findings underscore the importance of strategic public communication and the value of local media in crisis management.
