Preferences, Homophily, and Social Learning [PDF]
SSRN Electronic Journal, 2013 We study a sequential model of Bayesian social learning in networks in which agents have heterogeneous preferences, and neighbors tend to have similar preferences—a phenomenon known as homophily. We find that the density of network connections determines the impact of preference diversity and homophily on learning. When connections are sparse, diverse

SSRN Electronic Journal, 2011 We examine whether social preferences are determined by hormones. We do this by investigating whether markers for the strength of prenatal testosterone exposure (finger length ratios) and current exposure to progesterone and oxytocin (the menstrual cycle) are correlated with choices in social preference games.

Control of preferences in social networks [PDF]
49th IEEE Conference on Decision and Control (CDC), 2010 We consider the problem of deriving optimal advertising policies for the spread of innovations in a social network. We seek to compute policies that account for i) endogenous network influences, ii) the presence of competitive firms, that also wish to influence the network, and iii) possible uncertainties in the network model. Contrary to prior work in

Heterogeneous social preferences [PDF]
Journal of Economic Behavior & Organization, 2008 Recent research has shown the usefulness of social preferences for explaining behavior in laboratory experiments. This paper demonstrates that models of social preferences are particularly powerful in explaining behavior if they are embedded in a setting of heterogeneous actors with heterogeneous (social) preferences. For this purpose a simple model is

International Journal of Health Policy and Management, 2021 There are at least two reasons why health technology assessment (HTA) agencies need to seek process-based solutions to support the legitimacy of healthcare resource allocation, ie, (i) in pluralistic societies, the existence of often conflicting and ...
