We provide a generalization of Harsanyi (1955)'s aggregation theorem to the case of incomplete preferences at the … aggregation rules that are utilitarian in a generalized sense. Strengthening Pareto indifference to Pareto preference provides a …

Elasticity optimism
Imbs, Jean; Méjean, Isabelle - HAL - 2009
Estimates of the elasticity of substitution between domestic and foreign varieties are small in macroeconomic data, and substantially larger in disaggregated studies. This may be an artifact of heterogeneity. We use disaggregated multilateral trade data to structurally identify elasticities of...

Aggregating sets of von Neumann-Morgenstern utilities
Danan, Eric; Gajdos, Thibault; Tallon, Jean-Marc - HAL - 2010
We analyze the aggregation problem without the assumption that individuals and society have fully determined and … utilities, where it basically reduces to utilitarianism. In particular, aggregation rules may differ by the relationship between … individual and social indeterminacy. We characterize several subclasses of neutral aggregation rules and show that utilitarian …

One-Year Volatility of Reserve Risk in a Multivariate Framework
Appert-Raullin, Yannick; Devineau, Laurent; Pichevin, … - HAL - 2013
The one-year prediction error (one-year MSEP) proposed by Merz and Wüthrich has become a market-standard approach for the assessment of reserve volatilities for Solvency II purposes. However, this approach is declined in a univariate framework. Moreover, Braun proposed a closed-formed...
