This incentivizes the insiders to set even higher wages when the economy again gets better, as there are not as many insiders remaining as before, instead of letting the outsiders to again get jobs at earlier wages. WebbA comprehensive theory for the Soret effect (also called: Ludwig-Soret effect and thermal diffusion) is presented which incorporates both the thermodynamic contribution and the kinetic contribution.
