Behavioral economics has demonstrated systematic decision‐making biases in both lab and field data. Do these biases extend across contexts, cultures, or even species? We investigate this question by introducing fiat currency and trade to a colony of capuchin monkeys and recovering their preferences over a range of goods and gambles. We show that capuchins react rationally to both price and wealth shocks but display several hallmark biases when faced with gambles, including reference dependence… 

Capuchin monkeys do not show human-like pricing effects

Although monkeys demonstrated an understanding of which goods had which prices (consistently shifting preferences to cheaper goods when prices were increased), there was no evidence that such price information affected their valuation of different kinds of goods, suggesting that human pricing effects may involve more sophisticated human-unique cognitive capacities, such as a understanding of market forces and signaling.

On loss aversion in capuchin monkeys.

Three experiments with monkeys and humans consistent with a reinterpretation of their data that attributes their results not to loss aversion, but to differences between choice alternatives in delay of reinforcement are presented.

ON LOSS AVERSION IN CAPUCHIN MONKEYS

Three experiments with monkeys and humans consistent with a reinterpretation of their data that attributes their results not to loss aversion, but to differences between choice alternatives in delay of reinforcement are presented.

Endowment effect in capuchin monkeys

The data suggest that biased preferences rely on cognitive systems that are more evolutionarily ancient than previously thought—and that common evolutionary ancestry shared by humans and capuchins may account for the occurrence of the endowment effect in both species.

Magnitude-sensitive preference formation

A theory of magnitude-sensitive preference learning is developed that permits an agent to rationally infer its preferences for items compared with money options of different magnitudes and is shown how this theory yields classical and anomalous supply-demand curves and predicts choices for a large panel of risky lotteries.

Why Do Individuals Exhibit Investment Biases

Where do behavioral biases aecting investment decisions come from? We nd that a signicant proportion (about 20 to 56%) of investment biases such as home bias, loss aversion, performance chasing as

While the economic approach to human decision-making characterizes our choices in terms of how we maximize utility, in many cases, such an approach fails to predict the decisions we actually make.

An asymmetry of treatment between lotteries involving gains and losses in rhesus monkeys

Rhesus monkeys facing bets exhibited an asymmetry in the treatment of gains and losses comparable with that of humans, setting up a protocol that allowed two rhesus primates to make choices between lotteries involving either gains or losses.
