“…Taken together, these facts are consistent with the hypothesis that advisors care about supporting the career of their advisees even if that means a smaller influence of their own fields. An additional important finding is that larger fields (more productive and exhibiting more intergenerational field similarity) exhibit more cooperation among researchers, which is consistent with complementarities between socialization and productive efforts as in Cabrales et al (2011) and Albornoz et al (2016).…”

• We documents trends of mobility across fields in economics.• We find intergenerational field similarity is more prevalent in larger fields.• We show that researchers with different fields from their advisors are more likely to switch to highly demanded fields in the job market.• We also document a positive relation between field productivity and the median level of co-authorship at the field level. Abstract This note documents trends of socialization and intergenerational mobility across research networks (fields) in economics. Using data on advisor-advisee pairs, we find that intergenerational field similarity is more prevalent in larger and successful fields. We then show that researchers who do choose different fields than those of their advisors are more likely to switch to highly demanded fields in the job market. These results are consistent with the equilibrium of a model in which advisors' have concerns for their advisees' socialization and production outcomes. We also document a positive relation between field productivity and the median level of co-authorship at the field level, which is consistent with complementaries between socialization and productive efforts.JEL-Classification: A1, A19, A23, J62 .

“…It is, however, well-known that non-cooperative games of network formation with nominal lists of intended links are plagued by coordination problems (Myerson, 1991;Jackson and Wolinsky, 1996;Jackson, 2008;Cabrales et al, 2011). This is why it is extremely hard, if not impossible, to provide a full-fledged characterization of all possible stable networks.…”

We show that the more central minority agents are in the social network, the more they assimilate to the majority culture. We also show that denser networks tend to favor assimilation so that, for example, it is easier to assimilate in a complete network than in a star-shaped network. We show that the subgameperfect equilibrium is not optimal because there is not enough activity and assimilation. We then endogeneize the network and show under which condition the ethnic minorities either assimilate to or separated themselves from the majority group.JEL Classification: D85, J15, Z13

“…In particular, our framework is a generalization of the model in König et al (2014). This part of the paper is also related to the literature that combines strategic interactions with network formation, as in Bramoullè et al (2004), Cabrales et al (2010), Jackson and Watts (2002), , Goyal and Joshi (2003). 7 Relative to this literature, the framework that we provide is general and dynamic, i.e.…”

This paper investigates the role of strategic complementarities in the context of network games and network formation models. In the general model of static games on networks, we characterize conditions on the utility function that ensure the existence and uniqueness of a pure-strategy Nash equilibrium, regardless of the network structure. By applying the game to empirically-relevant networks that feature nestedness-Nested Split Graphs-we show that equilibrium strategies are nondecreasing in the degree. We extend the framework into a dynamic setting, comprising a game stage and a formation stage, and provide general conditions for the network process to converge to a Nested Split Graph with probability one, and for this class of networks to be an absorbing state. The general framework presented in the paper can be applied to models of games on networks, models of network formation, and combinations of the two.
