Dr. Sarah Iweala


Sarah is a former member of the Research Training Group Global Food. In her research, Sarah is interested in factors that motivate consumers to go for the ethical option when they have the choice. For her PhD she analysed the role of the warm glow of giving in different study set ups, including choice experiments and experimental online auctions. She collaborated with fellow researchers to analyze the choices of consumers in Germany, the UK and China. It is particularly this joint work that she enjoyed during her PhD.
