We investigate the effect of media information processing on policy preferences in the context of the COVID-19 crisis. For that purpose, we conduct a survey experiment to study the event of the publication of a highly regarded annual report about the state of the economy in Germany. In our experiment, individuals are exposed to information on a key economic statistic covered in the report which differs in terms of its medial framing. This design allows us to disentangle effects which are related to the original press released information and its coverage in newspaper articles. Our examination accounts for public evaluation of economic policy in general as well as important subdomains. We aim to inform about policy implications on the relationship between media coverage, belief updating and public opinion formation in times of economic recession and pronounced public interest in statistical reporting.

Experimental Details


The information which is provided to respondents stems from a highly regarded report about the state of the German economy by the German Council of Economic Experts (GCEE).

The annual report is presented to the public regularly in November and includes a press release pointing out key information from the comprehensive report. We employ both the original press release as well as its media coverage in large German newspapers which is generated by the publication of the GCEE report.

Experimental Design

Experimental Design
Our experimental design consists of four stages and four experimental groups. Survey respondents are randomly assigned to one of the three treatment arms which differ with respect to the framing of the information provided, or to the passive control group which does not receive any information.

In the first stage, we elicit respondents’ beliefs about a key economic statistic covered in the GCEE report.

In the second stage, random subsets of respondents are exposed to differently framed information on the key statistic:
- Treatment arm I: receives rather positively framed information from the GCEE report as covered by a German newspaper
- Treatment arm II: receives rather negatively framed information from the GCEE report as covered by a German newspaper
- Control group I (active): receives the original information from the GCEE
- Control group II (passive): does not receive any information

In the third stage, respondents are asked our outcome measures on the assessment of general COVID-19 policy and particular COVID-19 policies. Each of these outcomes are measured on an 11-point scale. As secondary outcomes, we investigate assessments of the usefulness and credibility of the information provided for those groups which receive information.

In the fourth stage, we elicit posterior beliefs about the key economic statistic covered in the GCEE report for those respondents who received information on the topic.
