This paper demonstrates that well-established biases in decision making under uncertainty can generate poverty traps. A theoretical framework is developed to demonstrate that: i) probability weighting and ambiguity attitude can lead individuals to erroneously undervalue profitable investments,...

This paper deals with estimating small tail probabilities of thesteady-state waiting time in a GI/GI/1 queue withheavy-tailed (subexponential) service times. The problem ofestimating infinite horizon ruin probabilities in insurancerisk processes with heavy-tailed claims can be transformed into...

The Basel Committee on Banking Supervision (BCBS) (2013) recently proposed shifting the quantitative risk metrics … system from Value-at-Risk (VaR) to Expected Shortfall (ES). The BCBS (2013) noted that - a number of weaknesses have been … identified with using VaR for determining regulatory capital requirements, including its inability to capture tail risk - (p. 3 …

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, we measure risk dependence among European insurers and reinsurers. The … results point to a relatively low insurance sector wide risk. Dependence among insurers is higher than among reinsurers. …

In arbitrage-free but incomplete markets, the equivalent martingale measure Q for pricing traded assets is not uniquely determined. A possible approach when it comes to choosing a particular pricing measure is to consider the one that is "closest" to the physical probability measure P, where...

In this paper, we extend the concept of mutual exclusivity proposed by Dhaene and Denuit (1999) to its tail counterpart and baptise this new dependency structure as tail mutual exclusivity. Probability levels are first specified for each component of the random vector. Under this dependency...

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 …. The risk measure characterized can be regarded as a mixed exponential premium. …
