主讲人简介：
Andre Veiga completed his Phd in Economics at the Toulouse School of Economics. He was then a postdoctoral fellow at Oxford University and joined Imperial College as an Assistant Professor in 2017. His research interests are in theoretical and empirical Industrial Organization, especially insurance, credit and healthcare markets.
摘要：
Should insurance prices vary with age? I consider competitive markets for lemons where a signal (eg, age) partitions consumers (eg, young and old). I study the continuum of policies between full community rating (CR, equal prices) and zero CR (no restriction on prices). CR increases welfare if high-cost markets exhibit greater adverse selection. I show how cost levels and risk adjustment affect optimal CR. I extend the model to arbitrary signal structures, multi-product firms, behavioural consumers, imperfect competition and environments where CR restores collapsed markets. In a calibration to US health insurance, optimal CR increase welfare by $730/person-year.
