The strategic role of reinsurance in the United Kingdom’s (UK) non-life insurance market

We demonstrate that by increasing the level of reinsurance, primary insurers increase their product-market share at the expense of rivals with lower reinsurance coverage in five main lines of insurance in the United Kingdom’s (UK) non-life insurance market. We use panel data drawn from statutory filings made by non-life insurers to the then UK regulator (FSA) over 1985 to 2010 period. We find that the influence of reinsurance and other financial variables on insurers’ growth in product-market share varies across lines of insurance business. Since reinsurance impacts on product-market outcomes in competitive non-life insurance industry, we conclude that reinsurance performs an important strategic function in insurance markets
