This paper examines how capital tax competition affects jurisdiction formation. We describe a locational model of public goods provision, where jurisdictions are represented by coalitions of consumers with similar tastes, and where the levels of taxation and local public goods provision within...

Following the ideas behind the Feynman approach, a variational wave function is proposed for the Fröhlich model. It is shown that it provides, for any value of the electron-phonon coupling constant, an estimate of the polaron ground state energy better than the Feynman method based on path...

We study the scattering of an electron of a 2DEG through a large point contact separating a region where the electrons are free and a region where the Rashba spin-orbit coupling is present. The scattering depends dramatically on the electron incidence angle showing double refraction within the...

The formation of spherical polaron clusters is studied within the Fröhlich polaron theory. In a dilute polaron gas, using the non-local statistical approach and the polaron pair interaction obtained within the Pekar strong coupling theory, the homogeneous phase results to be unstable toward the...

We consider renegotiation of social earnings insurance arrangements by majority voting in an economy where ex-ante identical individuals make unobservable private investments in education. We show that voting-based renegotiation can result in a higher expected level of investment in comparison...

The Uruguay Round was the most ambitious round of GATT negotiations ever undertaken. This paper offers an evaluation of possible effects of the Final Act of the Uruguay Round with a special focus on Canada. Our two main findings can be summarized as follows: (1)First, the estimated impacts of...
