This paper investigates risk-based premiums in ex-ante insurance guaranty schemes. Exchange rate risk is incorporated into the asset portfolio to reflect the growing practice of life insurers taking offshore risks for yield enhancement. The closed-form solutions of the risk-based premium charged by the insurance guaranty fund are derived. Our premium rating includes currency mismatches between assets and liabilities, and the effects of early closure, capital forbearance, and grace periods are fully explored. First, we discover that the insurance guaranty fund premium is underestimated if currency fluctuation uncertainty is overlooked. Second, the premium is higher under regulatory forbearance than it is under the Merton stock put option, which implies that the cost is substantial. Finally, we note that the premium increases with higher financial leverage and greater foreign exposure in the asset portfolio. The results of our analysis provide further insight for regulators to implement regulatory policies and insurance guaranty schemes.

I study dynamic hedging for variable annuities under basis risk. Basis risk, which arises from the imperfect correlation between the underlying fund and the proxy asset used for hedging, has a highly negative impact on the hedging performance. In this paper, I model the financial market based on correlated geometric Brownian motions and analyze the risk management for a pool of stylized GMAB contracts. I investigate whether the choice of a suitable hedging strategy can help to reduce the risk for the insurance company. Comparing several cross-hedging strategies, I observe very similar hedging performances. Particularly, I find that well-established but complex strategies from mathematical finance do not outperform simple and naive approaches in the context studied. Diversification, however, could help to reduce the adverse impact of basis risk.

The article analyzes the interconnectedness and gaps between two interrelated streams of literature, evolving in different time periods, by employing bibliometric tools. The research on the factors of life insurance demand started in the late 1960s and early 1970s, while more intensive works on the drivers of lapses in life insurance appeared during the 2000s. We map the research fields using our own criteria to create clusters and visualize the flow of knowledge within and between the clusters employing citation network analysis (CNA). We contribute by providing the most comprehensive systematic review that integrates both fields, additionally encapsulating studies on the demand for policy loans. The article detects the most important drivers of life insurance policyholder behavior during his/her lifetime and opens new horizons for future research.

Some people have optimistic expectations regarding their accident probability, and thus, refrain from purchasing adequate insurance. This study investigates how insurance firms use advertisements to lower the ratio of optimistic individuals in the market. The main results are as follows: first, the optimal level of advertisements is maximized when the insurance premium is moderate. Second, the maximum level of advertisement varies according to the degree of optimism, which is measured by the difference between accurate and optimistic accident probabilities. Third, the advertisement decision is affected by the free-rider problem, and the equilibrium number of insurance firms with advertisement is always larger than that of firms without advertisement in a competitive insurance market.
