In this paper we derive a market value for Guaranteed Annuity Optionusing martingale modeling techniques. Furthermore, we show how to construct a static replicating portfolio of vanillainterest rate swaptions that replicates the Guaranteed Annuity Option. Finally, we illustrate with historical...

We model and measure simultaneous large losses of the market value of insurers to understand the impact of shocks on the insurance sector. The downside risk of insurers is explicitly modelled by common and idiosyncratic risk factors. Since reinsurance is important for the capacity of insurers,...

This discussion paper has led to a publication in <A href="http://www.sciencedirect.com/science/article/pii/S001429211200044X">'European Economic Review'</A>, 56(4), 669-90.<P>We investigate the presence of moral hazard and advantageous or adverse selection in a market for supplementary health insurance. For this we specify and estimate dynamic models for health insurance...</p></a>

We study the dependence between the downside risk of European banks and insurers. Since the downside risk of banks and insurers differs, an interesting question from a supervisory point of view is the risk reduction that derives from diversification within large banks and financial...

This paper empirically analyzes moral hazard in car insurance using a dynamic theory of an insuree's dynamic risk (ex ante moral hazard) and claim (ex post moral hazard) choices and Dutch longitudinal micro data. We use the theory to characterize the heterogeneous dynamic changes in incentives...

This paper presents a new axiomatic characterization of risk measures that are additive for independent random variables. In contrast to previous work, we include an axiom that guarantees monotonicity of the risk measure. Furthermore, the axiom of additivity for independent random variables is...

This paper focuses on the relation between worker's productivity and retirement decision. Assuming that productivity follows geometric Brownian motion with drift, there exists such a level of productivity for which it is optimal to retire. The worker buys an insurance, which gives a constant...

This paper examines the impact of coinsurance exemption for prescription medicines applied to elderly individuals in Spain after retirement. To evaluate this coinsurance change we use a rich administrative dataset that links pharmaceutical consumption and hospital discharge records for the full...

We allow the preference of a political majority to determine boththe corporate governance structure and the division of profits betweenhuman and financial capital. In a democratic society where financialwealth is concentrated, a political majority may prefer to restraingovernance by dispersed...

We study the effects of the reform of the system of severance payments (TFR) of Italian employees on the cost and the access to credit for small and medium-size enterprises (SMEs). The most direct consequence of the reform is to reduce in the long run the amount of liquid assets available to...
