We consider some robust optimal portfolio problems for markets modeled by (possibly non-Markovian) jump diffusions. Mathematically the situation can be described as a stochastic differential game, where one of the players (the agent) is trying to find the portfolio which maximizes the utility of...

We study partial information, possibly non-Markovian, singular stochastic control of Itô--Lévy processes and obtain general maximum principles. The results are used to find connections between singular stochastic control, reflected BSDEs and optimal stopping in the partial information case. As...

We use the Itô-Ventzell formula for forward integrals and Malliavin calculus to study the stochastic control problem associated to utility indifference pricing in a market driven by Lévy processes. This approach allows us to consider general possibly non-Markovian systems, general utility...

Le recrutement constitue un enjeu majeur dans toutes les organisations. Pour être certaines de ne pas commettre d'erreur dans leurs recrutements, les entreprises font appel à toutes sortes de tests et particulièrement des tests de personnalité. En effet, l'intégration d'un nouveau salarié...

In this article we develop a dynamic model where an endogenous evolution of trust impacts a politician's choice for bribe-taking and tax re-distribution. The politician obtains utility from net income that comes from his wage income, tax embezzlements and bribe-taking, and he also has incentives...

This paper analyses the impact of the Sloping Land Conversion Program (SLCP) on rural labor migration in China. We use recent survey data from Ningxia Hui Autonomous Region and a difference-in-difference approach to assess the impact of the policy on labor migration decision. We find a...

La evolución contemporánea de las economías occidentales se ha caracterizado por un cambio estructural que ha llevado a la situación actual de fuerte terciarización. La economía española también ha participado del incremento de los servicios. El desarrollo capitalista moderno ha tenido...

Le renouvellement de la clientèle bancaire constituée par les très petites entreprises (TPE) est un élément déterminant de l'activité de financement des banques de réseaux. Ces TPE constituent l'essentiel de la clientèle professionnelle et les enjeux commerciaux sont importants. La...

Las transformaciones experimentadas por España a partir del Plan de estabilización Económica de 1959 han alterado la realidad de su economía pero también, y de una manera importante, la de su sector público. De hecho, la modernización económica exigía una racionalización de la parte de...

Nanotechnologies are often presented as breakthrough innovations, where technology transfer and knowledge-bridging will play a pivotal role in the industrial dynamics. This article investigates the model of knowledge transfer in the nanotechnologies in depth, by comparing it with the models of...
