Nous évaluons l'impact du pouvoir de négociation des syndicats sur l'inflation et l'emploi dans le cadre d'un modèle de contrat optimal à la Mac Donald & Solow [1981]. Nous considérons un jeu à la Stackelberg entre la banque centrale et les partenaires sociaux (entreprises et syndicats). Les entreprises et les syndicats négocient l'emploi et le salaire nominal, tandis que la banque centrale, qui joue le rôle de leader , fixe le taux d'inflation. Nous montrons qu'une diminution du pouvoir de négociation des syndicats tend à réduire le salaire nominal et l'emploi. Dans un tel contexte de banque centrale leader , la politique monétaire optimale consiste à augmenter le taux d'inflation optimal afin d'éviter une hausse du chômage. De plus, nous démontrons que l'augmentation du taux d'inflation optimal a des effets plus importants lorsque la banque centrale est faiblement conservatrice. Ces résultats plaident en faveur d'une réduction du conservatisme de la banque centrale pour compenser l'impact macroéconomique de la baisse du pouvoir de négociation des syndicats.

Millisecond pulsars (MSPs) are old neutron stars that spin hundreds of times per second and appear to pulsate as their emission beams cross our line of sight. To date, radio pulsations have been detected from all rotation-powered MSPs. In an attempt to discover radio-quiet gamma-ray MSPs, we used the aggregated power from the computers of tens of thousands of volunteers participating in the Einstein@Home distributed computing project to search for pulsations from unidentified gamma-ray sources in Fermi Large Area Telescope data. This survey discovered two isolated MSPs, one of which is the only known rotation-powered MSP to remain undetected in radio observations. These gamma-ray MSPs were discovered in completely blind searches without prior constraints from other observations, raising hopes for detecting MSPs from a predicted Galactic bulge population. ; This work was supported by the Max-Planck-Gesellschaft, the Deutsche Forschungsgemeinschaft through an Emmy Noether Research Grant [no.
