Abstract
The study provides empirical evidence for the effect of reinsurance on solvency, profitability, and taxes of primary insurers. Our main finding is that primary insurers increasing in the use of reinsurance exhibit lower capital ratios. This impact involves the segments of health insurance, composite insurance, title insurance, and non-life insurance. Our interpretation is that reinsurance and capital can be seen as substitutes for improving solvency. This implies that, by sharing their risk with reinsurers, primary insurers can benefit from a relief on capital. Additional outcomes display an important relationship between demand and supply of reinsurance at the firm level, as we observe that, growing in the used reinsurance; primary insurers are more prone to providing reinsurance to other firms.
