This paper analyzes the determinants of individual attitudes towards environmental action by means of an original PLSPM model of Environmental Awareness-Social Capital-Action (EASCA). Estimates build on survey data on 34.612 individuals from 42 different countries, as provided in the fifth wave...

In a classical experiment, Niederle and Vesterlund (2007) used the dichotomous choice of individuals between a piece rate and a tournament payment scheme as an indication of their propensity to compete. This paper reports results from a two person interaction of a similar type to analyze whether...

One of the main issues in the statistical literature of extremes concerns the tail index estimation, closely linked to the determination of a threshold above which a Generalized Pareto Distribution (GPD) can be fi tted. Approaches to this estimation may be classifi ed into two classes, one using...

In this study we empirically explore the capacity of historical VaR to correctly predict the future risk of a financial institution. We observe that rolling samples are better able to capture the dynamics of future risks. We thus introduce another risk measure, the Sample Quantile Process, which...

Under the Fundamental Review of the Trading Book (FRTB) capital charges for the trading book are based on the coherent expected shortfall (ES) risk measure, which show greater sensitivity to tail risk. In this paper it is argued that backtesting of expected shortfall-or the trading book model...

Our interest in this paper is to explore limit theorems for various geometric functionals of excursion sets of isotropic Gaussian random fields. In the past, limit theorems have been proven for various geometric functionals of excursion sets/sojourn times (see [4, 13, 14, 18, 22, 25] for a...

In this study, we examine different quantitative methods to recover the risk neutral distribution function associated to the prices of option on bank shares. This is useful for a wide range of applications, such as determining the implicit State guarantee that systemic financial institutions...

We propose a new approach to analyse the effect of diversification on a portfolio of risks. By means of mixing techniques, we provide an explicit formula for the probability density function of the portfolio. These techniques allow to compute analytically risk measures as VaR or TVaR, and...

The French market for specialist physician care has a dual structure, including a sector 1 with regulated fees, and a sector 2 where physicians can freely choose fees. Patients who undergo a sequential search process for the best medical offer develop a reservation fee decision rule. We analyzed...
