Investigating imprecision in preferences and its possible consequences for economics and economic choices. When people's preferences are not clear, their choices become variable and susceptible to theoretically irrelevant influences. Examples can be found in surveys of preferences intended to inform public policy in areas such as health, safety and the environment. Understanding the nature of imprecision in people's values and choices is also likely to be crucial for consumers' ability to advan ....Investigating imprecision in preferences and its possible consequences for economics and economic choices. When people's preferences are not clear, their choices become variable and susceptible to theoretically irrelevant influences. Examples can be found in surveys of preferences intended to inform public policy in areas such as health, safety and the environment. Understanding the nature of imprecision in people's values and choices is also likely to be crucial for consumers' ability to advance their interests in our complex, choice-filled society. We plan to draw out some of the implications of our experimental work on preference imprecision for consumer behaviour and existing business practices, including the regulation of fair trading.Read moreRead less
