Experimental Design

Experimental Design
The study consists of two part of the experiment: part I, through the randomized controlled trial (RCT) we analyse whether the choice of greener alternatives is influenced by the presence of information. The incentive to participate for the families is a supermarket voucher for grocery. Part II, through a discrete choice experiment, the authors explore the role of different attributes (environmental sustainability and price) on the food purchasing choices.
