We describe a prototype approach to flexible modelling for maxima observed at sites in a spatial domain, based on fitting of max-stable processes derived from underlying Gaussian random fields. The models we propose have generalised extreme-value marginal ...
In this paper, we present a simulation-based investigation of the potential benefit of route-guidance information in the context of risk-sensitive travelers. We set up a simple two-route scenario where travelers are repeatedly faced with risky route-choice ...
Vulnerability is estimated in terms of the effects that IEMI may induce to the services provided by the facility under study. We estimate the vulnerability by considering three variables: the likelihood, the risk, and the hardness. The different parameters ...
This thesis consists of three chapters. The first chapter endogenizes technological change by introducing a stylized innovation process driven by a R&D–dependent Poisson process in a Cox, Ingersoll and Ross (1985) production economy. The model reproduces s ...
We study survival, price impact, and portfolio impact in heterogeneous economies. We show that, under the equilibrium risk-neutral measure, long-run price impact is in fact equivalent to survival, whereas long-run portfolio impact is equivalent to survival ...
Most accounts of the function of anterior insula in the human brain refer to concepts that are difficult to formalize, such as feelings and awareness. The discovery of signals that reflect risk assessment and risk learning, however, opens the door to forma ...
This paper presents an equilibrium model in a pure exchange econ- omy when investors have three possible sources of heterogeneity. In- vestors may di§er in their beliefs, in their level of risk aversion and in their time preference rate. We study the impac ...
We investigate routing policies for shortest path problems with uncertain arc lengths. The objective is to minimize a risk measure of the total travel time. We use the conditional value-at-risk (CVaR) for when the arc lengths (durations) have known distrib ...
Available risk analysis techniques are well adapted to industry since they were developed for its purpose. All hazards met in industry are also present in research/academia (although quantities of some hazardous substances are smaller). Still, because of i ...
Attitudinal attributes play an important role in behavior of individuals in various contexts. In this study we focus on the travel behavior and our main objective is to come up with segments of individuals that have different mode choice preferences with t ...
