The paper is a simplified exposition of an early combined phase I-phase II method for linear programming. The method works from an infeasible start. Besides, there is no need for regularity conditions if the method is applied to a primal-dual formulation.

Swiss intitutional investors hold approximately 19% of their wealth in property, and the bulk of the allocation to property is housing. The financial reasons which are often given to motivate this investment strategy are twofold. Firstly, property returns are hypothesised to be lowly correlated...

We propose an alternative apporach to stochastic programming based on Monte-Carlo sampling and stochastic gradient optimization. The procedure is by essence probabilistic and the computed solution is a random variable. The associated objectiev value is doubly random, since it depends two...

Earnings management can be defined as a purposeful intervention by executives into a firm's financial reporting process in order to secure some gains for themselves, for some firm stakeholders (e.g. investors), or from other firm stakeholders (e.g. debtholders). In this context, a firm's...

The preemptive role of the mean of payment in a takeover contest is analysed following the bidder's point of view.

This paper proposes and tests an approximation of the solution of a class of piecewise deterministic control problems, typically used in the modeling of manufacturing flow processes. This approximation uses a stochastic programming approach on a suitably discretized and sampled system. The...

We propose a stochastic programming approach for quantitative analysis of supply contracts, involving flexibility, between a buyer and a supplier, in a supply chain framework.

We use a Ricardo-Viner model to study the determinants of the supply of outmigration in developing countries in a model with neterogenous households. We assume that heterogeneity and migration costs prevent households from total migration.

In this paper, we use the hedonic approach to estimate the value of a statistical life based on the 1995 Swiss Labour Force Survey (SLFS) and the 1994 Swiss Wage Structure Survey (SWSS). Roughly, the value of a statistical life in Switzerland ranges from CHF 10 to 15 million (6.5-9.5 million...

Cette etude analyse le lien entre la disparite regionale du chomage et la politique migratoire suisse a l'aide de la courbe de Beveridge (ou U-V). Cette derniere a ete largement utilisee par d'autres auteurs pour etudier l'effet du chomage de longue duree et les mismatchs notamment. Notre...
