, connections increase over time, but homophily on gender and ethnicity is relatively constant across time, university residences …, and different network layers. At the individual level, homophilous tendencies are persistent across time and network … layers. Furthermore, we see assortativity in homophilous tendencies. There is weaker, albeit significant, homophily over …

Many data situations require the consideration of network effects among the cross-sectional units of observation. In … this paper, we present a generalized panel model which accounts for two features: (i) three types of network effects on the … error components, and (ii) higher-order network effects due to ex-ante unknown network-decay functions or the presence of …

The network model's first-order conditions are used to derive an … underlying network structure can inform us about the potential gains from policies that increase economic activity in specific …

We develop and estimate a model of student study time on a social network. The model is designed to exploit unique data …: own study time may depend on friend study time in a heterogeneous manner. Social network data allow us to embed study time …

. Furthermore, the larger the number of behavioral traits that students share, the higher the overall homophily. Using network … econometrics, we show that the observed homophily is not only an outcome of endogenous network formation, but is also a result of … other demographic characteristics (Jackson, 2010). We present novel evidence on an understudied source of homophily …
