Recommendations:
The objective of this question is unclear, that is, it is unclear what respondents are supposed to do. Are they supposed to provide their estimate of the prices and the repayment rate in 12 months? Are they supposed to provide the optimal ratio of price and repayment rate? Or something else? Given that the question objective is unclear, we are not able to provide a concrete suggestion for improvement but only some general recommendations.
We recommend to rephrase the explanation of the relationship between interest and inflation rate to break down the complexity of the topic as much as possible for the participants.
Especially the misconception that the loan will be repaid faster if you pick a higher repayment rate or that it takes longer if you pick a rate of less than 500 Euros should be corrected. This could eventually be accomplished by including the statement that the repayment time is the same in all answer categories. Alternatively or in addition, a statement on the duration of the loan repayment could be included.
Additionally, the way how the repayment rates are calculated should be explained, i.e. which interest rates are at the base of these calculations.
Finally, the recommendation for question 1 should also be adopted here, that is, the amount of 1.500 Euros/1.700 Euros should be reduced.
