We ran a controlled laboratory experiment to examine whether ChatGPT's aid can increase the participants' performance in three different—reading and writing, mathematical problem-solving, and computational thinking—tasks. We find that the math score significantly decreases with ChatGPT's...

Time is a crucial determinant of deception, since some misreporting opportunities come as a surprise and require an intuitive decision while others allow for extensive reflection time. To be able to pursue a deceptive strategy, however, a subject must be aware of the misreporting opportunity....

We examine whether belief-based preferences - caring about what transgressors believe - play a crucial role in punishment decisions: Do punishers want to make sure that transgressors understand why they are being punished, and is this desire to affect beliefs often prioritized over distributive...

Many committees—juries, political task forces, etc.—spend time gathering costly information before reaching a decision. We report results from lab experiments focused on such information-collection processes. We consider decisions governed by individuals and groups and compare how voting...

This paper examines the effect of peers on individual risk taking. In the absence of informational motives, we investigate why social utility concerns may drive peer effects. We test for two main channels: utility from payoff differences and from conforming to the peer. We show experimentally...

We conducted a lab experiment to examine (1) whether luck-based income influences honesty in a subsequent, unrelated decision, (2) whether the perceived agency over an uncertain event affects the interplay between luck and honesty, and (3) whether accumulated previous luck-based incomes...

Does being lucky (or unlucky) affect honest decision-making? We examine (1) whether luck-based income strengthens or erodes the moral value of honesty; (2) whether the perceived level of agency over an uncertain event affects the relationship between luck and honesty; and (3) whether accumulated...

We examine how people redistribute income when there is uncertainty about the role luck plays in determining opportunities and outcomes. We elicit redistribution decisions from a U.S.-representative sample who observe worker outcomes and whether luck magnified workers' effort ("lucky...
