abstract
We propose a perfect empathy model of cultural transmission to capture the evolution of preferences
in a population. Unlike existing imperfect empathy models, focusing on stable interior equilibria, we
demonstrate that a corner outcome will eventuate. However, which corner outcome emerges is unknown,
and depends on the interplay of ‘‘history’’ and ‘‘expectations’’.

1. Introduction
The canonical model of utility maximization in economics as-
sumes preferences are given. But preferences are not written in
stone—they evolve over time. The economics literature distin-
guishes between two approaches to capture the evolution of pref-
erences. First, the indirect evolutionary approach postulates that
preferences determine payoffs via their effect on behavior. Inso-
far as success translates into greater reproductive success (or in-
vites copying), evolutionary pressures will shape the distribution
of preferences in society (e.g., Dekel et al., 2007).

Second, the cul-
tural transmission approach argues that parents ‘‘invest’’ in so-
cializing their offspring, imprinting certain preferences, values and
beliefs in the next generation.
Two models of cultural transmission exist. Models of imperfect
empathy assume parents prefer their offspring to have similar pref-
erences or beliefs as they themselves have (e.g. Bisin and Verdier,
2000, 2001a,b) hereafter BV, (Tabellini, 2008), and evaluate future

Examples of the application of evolutionary models to explain the evolution of

payoffs for offspring using their own preferences. This approach
reflects the deep value associated with certain preferences (pro-
social preferences, trusting behavior, etc.). In contrast, models of
perfect empathy assume parents want to imprint sets of prefer-
ences in their offspring aimed at maximizing the children’s pay-
offs. A small literature on imperfect empathy models has emerged,
but little systematic work has been done in the domain of im-
printing preferences for maximum offspring payoffs. Perhaps this
is because such models appear reminiscent of the literature on
evolution and replicator dynamics. For example, BV 2001 write
that ‘‘cultural transmission mechanisms characterized by perfect
altruism imply dynamics of the distribution of preferences which
converge to degenerate distributions concentrated on those pref-
erences which maximize fitness’’ (p. 278). This is also what hap-
pens in a model where evolutionary pressure selects for maximum
fitness.
However, the commonality between cultural transmission
models and evolutionary pressures is only superficial. They are
fundamentally different in the following sense: evolutionary
pressures operate strictly via differences in current performance,
cultural transmission accounts for the future as well. That is,
since parents consider the future and form expectations about
the environment within which their offspring will reside, the
eventuating equilibrium trajectories and steady states may be
quite different, depending on these expectations. That is the focus
