SUMMARY:phd seminar - Mathias Silva Vazquez*\, Tizie Bene**

DESCRIPTION:*This presentation will summarize a new econometric approach fo
 r parametric income distribution analysis. Two recent strands of literature
  are bridged under this approach. Firstly\, the literature on parametric co
 rrections for income data sources evidenced to be prone to the problem of '
 missing rich' such as household surveys. A new 'missing rich'-expanded para
 metric Generalized Lorenz curve form is proposed to account for a variety o
 f high-income data issues such as under-reporting\, top-coding\, and/or und
 ersampling. Secondly\, a step-by-step procedure is introduced for the purpo
 se of Bayesian inference on this model's parameters\, including optimizatio
 n of the correction quantities/margins for 'missing rich'. Procedures for t
 he ellicitation of prior probabilities for the model's parameters\, computa
 tional algorithms for parameter inference\, and posterior checks for model 
 criticism are proposed based on recent Approximate Bayesian Computation (AB
 C) methods for simulation-based Bayesian inference. The performance and com
 putational properties of this approach to inference are illustrated through
  grouped- and micro-data examples on simulated data and on EU-SILC data.**I
 n many developing economies\, formal insurance companies struggle to settle
 . People often mitigate risk by making insurance arrangements with each oth
 er\, thus creating informal risk-sharing networks.Whereas in developed econ
 omies we observe the opposite situation. People rely more on formal insuran
 ce to cover their risks and less on informal links. A very recent empirical
  literature suggests that the introduction of formal insurance products aff
 ects informal risk-sharing among individuals. Either it strengthens the sol
 idarity or it reduces it.This work-in-progress is the first to tackle this 
 issue from a theoretical viewpoint. To do so\, we use a network-based appro
 ach. I introduce formal insurance into the model of formation of risk-shari
 ng networks by Bramoullé and Kranton (2007). To the benchmark where indivi
 duals commit to sharing monetary holdings equally with a linked partner\, I
  add the possibility for each agent to take out formal insurance. Prelimina
 ry results establish a relation between the structure of the risk-sharing n
 etworks that emerged and the situation in the insurance market.\\n\\nContac
