This study will use a conjoint survey experiment to test the importance of production and process performance for political trust. The survey is fielded during the third week of school closures in Denmark (March 30th-April 6th) due to the coronavirus (covid-19). The survey experiment tests the effect of production performance outcomes (fatality rate, economic costs) and process performance outcomes (equality in health, equality in economic costs, use of cellphone data) on political trust and the respondents’ preferred choice of strategy towards the coronavirus.

The survey experiment uses a conjoint design. Respondents are either presented with the hypothetical outcomes of one strategy (1/3 of the respondents) or two strategies (2/3 of the respondents) that vary on five dimensions. The respondents are told to imagine that the government is considering the strategy/the strategies in the fight against covid-19 and are asked to score the strategy/the strategies in relation to political trust and prefered choice of strategy.
The survey experiment uses a conjoint design. Respondents are either presented with the hypothetical outcomes of one strategy (1/3 of the respondents) or two strategies (2/3 of the respodents). The respondents with two strategies are thus able to compare, while the respondent with only one strategy will have no provided reference point. The respondents are told to imagine that the government is considering the strategy/the strategies in the fight against covid-19. The strategies vary on five dimensions (which are presented randomly):
1) The fatality rate [0.1-0.3%,0.5-1%, 3-5%] 2) The economic costs [less than the 2008 financial crises, about the same as the 2008 financial crises, more than the 2008 financial crises] 3) Use of GPS data from cellphones [yes, no]
4) Who will be able to get tested for the virus [all who have a need, only the very ill, only the very ill and those that are able to pay for test]
5) Who will suffer from most from the economic costs (all equally, low-wage earners and vulnerable groups]

Experimental Design
The survey experiment uses a conjoint design. Respondents are either presented with hypothetical outcomes of one strategy (1/3 of the respondents) or two strategies (2/3 of the respodents). The respondents are told to imagine that the government is considering the strategy/the strategies in the fight against covid-19. The strategies vary on five dimensions (which are presented randomly):
1) The fatality rate (three outcomes)
2) The economic costs (three outcomes)
3) Useage of GPS data from cellphones (two outcomes)
4) Who will be able to get tested for the virus (three outcomes)
5) Who will suffer from most from the economic costs (two outcomes)
Respondents are assigned one or two of the 108 strategies randomly.

Sample size (or number of clusters) by treatment arms
As the study uses a conjoint design the concept of treatment arms is not applicable. The study does, however, divide the respondents into two groups. One group will only be presented with one strategy (approximately 650 individuals), while the other group (1,350) is presented with two strategies.
