We analyze the effect of enhanced annuities on an insurer engaging in individualunderwriting. We use a frailty model for the heterogeneity of the insured populationand model the individual underwriting by a random variable that positivelycorrelates with the corresponding frailty factor. For a...

In the last few years it has been possible to observe decreasing interest margins forGerman universal banks. At the same time, institutions increasingly moved partof their business from interest to fee-earning activities. This study analyzes thedeterminants of non-interest income and its impact...

Despite extensive research interest in the last decade, the banking literature has notreached a consensus on the impact of bank mergers on deposit rates. In particular,results on the dynamics of deposit rates surrounding bank mergers vary substantiallyacross studies. In this paper, we aim for a...

In the presence of transactions costs, no matter how small, ar-bitrage activity does not necessarily render equal all riskless rates ofreturn. When two such rates follow stochastic processes, it is not opti-mal immediately to arbitrage out any discrepancy that arises betweenthem. The reason is...

In this paper we propose a smooth transition tree model for both the conditionalmean and variance of the short-term interest rate process. The estimation of suchmodels is addressed and the asymptotic properties of the quasi-maximum likelihoodestimator are derived. Model specification is also...

It has been found in the literature that the overnight Eurodollar rate and the effective Fedfunds rate exhibit similar calendar-day effects caused by the Federal reserve regulationsand accounting conventions and characteristics of the Fed funds market. However, it wasnot documented whether the...
