The empirical results clearly indicate the importance of heterogeneous portfolio characteristics while choosing a type reinsurance that minimizes the underwriting risk and/or maximizes the underwriting profits. As a result, taking into account varying factors, such as risk type, variability in insurance coverage, retention levels, and varying insurance
and reinsurance premiums, can give more robust and realistic insights into the effects of reinsurance on an insurer's risk–profitability profile. Hence, future research on optimal financial and risk management choices and portfolio management should consider heterogeneous portfolios while determining the effects of different financial and risk management tools (e.g., financial and risk hedging) on companies'risk–return profiles.
