- "Other People's Money: The Role of Reciprocity and Social Uncertainty in Decisions for Others" (with Ivo Vlaev, Nicholas Wright, Antoinette Nicolle, Paul Dolan, Raymond Dolan) [May 2016]
Abstract: Many important decisions are taken not by the person who will ultimately gain or lose from the outcome, but on their behalf by somebody else. We examined economic decision-making about risk and time in situations in which deciders chose for others who also chose for them. We propose that this unique setting, which has not been studied before, elicits perception of reciprocity that prompts a unique bias in preferences. We found that decision-makers are less patient (more discounting), and also more risk-averse for losses than gains, with other peoples' money, especially when their choices for others are more uncertain. Those results were derived by exploiting a computational modelling framework that has been shown to account for the underlying psychological and neural decision processes. We propose a novel theoretical mechanism - precautionary preferences under social uncertainty - which explains the findings. Implications for future research and alternative models are also discussed.
- "The impact of price frames on consumer decision making: Experimental evidence" (with Steffen Huck, Julia Schmid) [October 2015]
Abstract: We present a laboratory experiment on the impact of price framing on consumer decision making. Consumer subjects face a search market where two sellers offer a homogeneous good. We examine six different price frames with linear per-unit pricing (that is displayed as such) serving as a benchmark. We find that all frames deviating from the benchmark have some negative impact on consumer decision making. The most striking result concerns drip pricing (where prices are decomposed into three elements and "dripped in" during the purchasing process). While leaving the actual decision problem unchanged, drip pricing wipes out 22% of consumer surplus.
Price framing research
Recently, with Steffen Huck, we conducted a laboratory experiment that investigated the effects of price framing on decision making as if in a retail setting. Prices frames encountered include '3 for 2', 'price was x now y', 'sale ends tomorrow', 'price is x while stocks last' and '...plus shipping'.
The report, entitled "The effects of price framing on consumer decision making", is available at: http://www.oft.gov.uk/shared_oft/economic_research/OFT1226.pdf. A working paper is available above.
Media coverage of the report include:
Throughout the year, we run experiments both online and in our lab in Drayton House. Typically, this involves making decisions at a computer. If you take part, you can earn money as well as helping contribute to our research.
You can register to join our participant database through our experiment recruitment page at https://else.econ.ucl.ac.uk/experiments. You will then receive invitations to take part in individual experiments.
