Is the new Illinois cigarette tax really helping to deter people from smoking? Would a ban on sugary drinks and soda really help curb the obesity epidemic? Does offering incentives like money or candy motivate children to perform better in school? This hour on Focus, we’ll talk about what influences our behavior. We'll delve into the idea of a “sin” tax, why we use them and if they have an impact on our decisions with Professor of Economics at the Institute of Government and Public Affairs at the UIUC Fred Giertz. Edward Deci, a Professor of Psychology and Social Sciences at the University of Rochester, also joins the program to answer questions about peer pressure, money as a motivator, stereotypes and how the world around us affects how we act and the decisions we make.
