Deregulation, Pricing Strategies, and Claim Behavior in the Taiwan Automobile Insurance Market

Stringent pricing regulations have long been in effect in the Taiwan automobile insurance market. In April 2009, a pricing deregulation was adopted, enabling insurers to establish their own auto insurance premium rates. This study examines the effects of deregulation in terms of three hypotheses that we propose pertaining to market shares, loading factors, and last policy month claims. The quantitative analysis results show that pricing deregulation prompts insurers to lower their rates. The effects of deregulation for insurers are determined by not only the decision to deduct premiums and the deduction percentages, but also by policy type.
