Abstract

We present evidence of product market adjustments and asset reorganizations from the largest ever shift in risk regulation in a developed insurance market. Using proprietary data on insurance risk exposures from the Bank of England, we develop a measure of regulatory constraints that is plausibly exogenous to shifts in demand. After the regulatory shift, constrained insurers reduce underwriting of traditional insurance, which became more capital intensive, and alter product composition from traditional to non-traditional-non-insurance products that offer no protection to households. Large insurers slow down, but small insurers completely pull out of traditional underwriting. Constrained insurers undergo asset reorganizations, and small insurers are more likely to be fully taken over. As a result, there is significant decline in traditional insurance from £30 billion in 2002 to £5 billion in 2015 and increase in market concentration with the share of top 10 insurers increasing from 60% in 2002 to 80% in 2015. Our findings imply that the scarcity of traditional insurance after the regulatory shift is particularly pronounced for households that match with small insurers.
