Abstract
We are launching a survey that elicits consumer preferences over inflation. The survey embeds an RCT, featuring six information treatments and one control group. The survey also includes questions that explore potential rationales for preferences expressed; vignettes--wherein random numbers for long-run inflation are presented--that elicit preferences in hypothetical contexts; and a task that confronts respondents with a trade-off between stabilizing inflation and stabilizing unemployment.

Interventions

Intervention(s)

Our RCT features five information treatments, administered between subjects:

T1 Friedman.
T2 ELB.
T3 Firms.
T4 Wages.
T5 Assets.

Following the main interventions, we present respondents with economic vignettes, which provide a random, hypothetical number for future long run inflation. The vignettes elicit respondents' expectations for economic variables and expected changes in their own economic behavior.

Primary Outcomes

Primary Outcomes (end points)
We have two primary outcome variables:
1. Individual-level inflation preferences elicited following the interventions.
2. The individual-level difference between inflation preferences elicited prior to the intervention and preferences elicited following the intervention.
Primary Outcomes (explanation)

Secondary Outcomes

Secondary Outcomes (end points)
People are asked to assign a relative weight on both objectives within the dual mandate of the Fed (price stability and maximum employment).

Experimental Design

Experimental Design

We plan to administer a nationally representative survey of US respondents. Our survey elicits inflation preferences at two different points. The first elicitation precedes an RCT component, which presents one of six information treatments (including control). The second preference elicitation follows the RCT. The survey also includes questions that explore potential rationales for preferences expressed; vignettes that elicit preferences in hypothetical contexts; and a task that confronts respondents with a trade-off between stabilizing inflation and stabilizing unemployment.
