There has been extensive research on social networks and methods for specific tasks such as: community detection, link prediction, and tracing information cascades; and a recent emphasis on using temporal dynamics of social networks to improve method performance. The underlying models are based on structural properties of the network, some of which we believe to be artifacts introduced from com...
This paper constructs a quantitative lifecycle model with uninsurable labor income and aggregate housing return risk to assess how Korean households make saving and portfolio allocation decisions. The model incorporates the special roles housing plays in the portfolio of households: collateral, a source of service flows, as well as a source of potential capital gains or losses. In the model, a ...
In this paper we investigate wealth inequality/polarization properties related to the geometry of the support of the limit distribution of wealth in economies characterized by equal opportunities and uninsurable individual risk. We work out two simple successive generation models, one with stochastic human capital accumulation and one with R&D, and prove that intense technological progress make...
Both contextual risk and sensitive parenting have been associated with children's social However, it is not clear how sensitive parenting might impact children's social skill development in the context of accumulation of risk.
