Aggregating over risk and time in risky intertemporal choice: which order?

(joint work with Xiao Yu)


This paper studies how people aggregate over risk and time when evaluating
intertemporal lotteries. In an experiment, subjects are asked to report
their present certainty equivalents of receiving a lottery at two different
points in time. These two lotteries are perfectly positively correlated,
perfectly negatively correlated, or independent. People who first aggregate
over risk, are insensitive to intertemporal correlations. We measure
non-parametric degrees of correlation aversion and disentangle them into
positive correlation aversion and negative correlation seeking. Subjects
were both positive correlation averse and negative correlation seeking. They
were found to be intertemporal correlation averse across lotteries and time
frames. The results show that subjects aggregate first over time, or
recursively over risk and time. Two framings were considered between
subjects: one that encouraged subjects to first aggregate over risk, and
another one that encouraged them to first aggregate over time. While these
framings resulted in lower present certainty equivalents for the framing
that encouraged to aggregate first over risk, they did not affect degrees of
intertemporal correlation aversion. Thus, subjects consistently aggregated
first over time or recursively, even in the framing that encouraged to
aggregate first over risk.

TITLE: Teaching Norms in the Streets: An Experimental Study (joint with
Thijs Brouwer and Marie Claire Villeval)

ABSTRACT: We study parents' tendency to enforce a social norm in the
presence and absence of a child in a natural, but controlled setting. Given
the central role of both parental socialization efforts and norm-enforcement
in guaranteeing the stability of social norms in society, parents play a
vital role in transmitting norm compliance to the younger generation. We
stage three scenes, including a norm violation, a helping opportunity, or
both in the vicinity of public elementary schools. We vary whether the child
is around or not and test whether parents are more likely to engage in (i)
direct punishment, (ii) indirect punishment through withholding help, or
(iii) helping behavior. We find that parents accompanying a child, in
contrast to parents alone, are more likely to engage in direct punishment
following a violation and are more likely to help in the absence of one. We
do not find that parents withhold help significantly more often as a means
of indirect punishment, even though the difference goes in the predicted
direction. In order to explore the mechanism behind our results, we conduct
a survey among parents not in our sample to elicit the social
appropriateness of the violation and the subsequent helping behavior.
