Question 1: Sustainable food choices You will be discussing the analysis and results presented in Hansen, P. G., Schilling, M., & Malthesen, M.S. (2019). Nudging healthy and sustainable food choices: three randomized controlled field experiments using a vegetarian lunch-default as a normative signal. Journal of Public Health.1The first step will be to carefully read the paper. All main analysis in this paper uses methodology that has been covered in your coursework.

Question 1.1:Summarize the article’s main finding and highlight the contribution you deem most important and most surprising.

Question 1.2:Compare any two experiments of the paper in your own words: who are the treated units,what is the response variable and what is the treatment? Discuss the role of randomization and the differences in the treatment choices. Why did the authors rely on multiple experiments?

Question 1.3:Discuss considerations of internal and external validity throughout the whole study(all three experiments), highlighting potential trade-offs in general and how they relate to the studies carried out.

Question 1.4:The paper presents group differences in a plot and discusses these in text. Pick one comparison and carry out step-by-step the hypothesis testing (with the𝛼value of your choice) for a difference in proportion.

Question 1.5:The paper discusses some differences between men and women. Present a brief outline of a study that you would design to get a more detailed view of these differences and the potential reasons behind them
