We analyze a standard employee selection model given two institutional constraints: First, professional experience perfectly substitutes insufficient formal education for insiders while this substitution is imperfect for outsiders. Second, in the latter case the respective substitution rate...

This paper proposes a new model called Fourier-GARCH that is a modification of the popular GARCH(1,1). This modification allows for time-varying first and second moments via means of Flexible Fourier transforms. A nice feature of this model is its ability to capture both short and long run...
