Abstract
We study the effects of information treatments regarding recent inflation rates or monetary policy targets and forecasts on inflation expectations of households and firms across countries and time using many RCTs implemented in different countries over time.

Experimental Details

Interventions

Intervention(s)
In each RCT, some randomly selected individuals are presented with information about either recent inflation, the central bank's inflation target, the central bank's inflation forecast, or some combination of these during the course of a survey, whereas other participants are not. We then study the effects of this information on the inflation expectations of the participants.

Experimental Design

Experimental Design
Random allocation of survey participants to control and treatment(s) groups. Treatments receive information about recent inflation, monetary policy inflation target, and/or monetary policy inflation forecast. We study how inflation forecasts change (or not) in response to this information relative to control group that is not provided with information.
Experimental Design Details
Randomization Method
Done by survey providers.
Randomization Unit
Individuals.
Was the treatment clustered?
No

Experiment Characteristics

Sample size: planned number of clusters
Depends on the survey
Sample size: planned number of observations
Depends on the survey. Nielsen surveys are ~20,000 individuals. ECB surveys are around 10,000. Atlanta Fed survey ~300 firms. New Zealand survey is about 3,000 firms. Uruguay survey is ~500 firms but there is variation over time across survey waves within each country.
Sample size (or number of clusters) by treatment arms
Depends on the survey. Nielsen has control of ~5,000, with 1-2,000 per treatment. ECB is similar. Atlanta Fed and uruguay are split evenly between control and one treatment group. New Zealand has ~500 in control and 50 in each treatment arm but there is variation over time across survey waves within each country.
Minimum detectable effect size for main outcomes (accounting for sample design and clustering)
