New fast estimation methods stemming from control theory lead to a fresh look at time series, which bears some resemblance to "technical analysis". The results are applied to a typical object of financial engineering, namely the forecast of foreign exchange rates, via a "model-free" setting,...

We are settling a longstanding quarrel in quantitative finance by proving the existence of trends in financial time series thanks to a theorem due to P. Cartier and Y. Perrin, which is expressed in the language of nonstandard analysis (Integration over finite sets, F. & M. Diener (Eds):...

Model uncertainty, in the context of derivative pricing, can be defined as the uncertainty on the value of a contingent claim resulting from the lack of precise knowledge of the pricing model to be used for its valuation. We introduce here a quantitative framework for defining model uncertainty...

Household models estimated on labour supplies alone generally assume non-market time to be pure leisure. Previous work on collective household decision-making is extended here by taking domestic work into account in the Chiappori et al.'s (2002) model. Derivatives of the household "sharing rule"...

We analyse how physicians respond to contractual changes and incentives within a multitasking environment. In 1999 the Quebec government (Canada) introduced an optional mixed compensation system, combining a xed per diem with a partial (relative to the traditional fee-for-service system) fee for...

This paper analyzes the interaction between migrants income and remittances and between remittancesand the labor supply of residents. The model is cast as a two-period game with imperfect informationabout the residents' real economic situation. Residents subject to a good economic situation may...

A premature death unexpectedly brings a life and a career to their end, leading to substantial welfare losses. We study the retirement decision in an economy with risky lifetime, and compare the laissez-faire with egalitarian social optima. We consider two social objectives: (1) the maximin on...

This paper examines the intrahousehold ressource allocation in Egyptian married couples and its impact on females labor supply. Using data from the Egyptian Labor market and Panel Survey of 2006, we estimate a discrete-choice model for female labor supply within a collective framework. The...

This paper is devoted to the analysis of the General Practitioners' (GPs) labour supply, specifically focusing on the physicians' labour supply responses to higher compensations. This analysis is mainly aimed at challenging the reality of a ‘backward bending' form for the labour supply of GPs....
