This multiple-curve model satisfies the main no-arbitrage and market requirements (such as nonnegative LIBOR-OIS spreads) by construction. The use of multidimensional affine processes as driving motions ensures the analytical tractability of the model. We provide pricing formulas for caps, swaptions and basis swaptions and discuss an efficient numerical implementation. Furthermore, the connection between the affine LIBOR setup and the 'classical' LIBOR market models is clarified. We present also some new examples of affine processes on $R^2_+$ which admit explicit solutions of the Riccati equations. We conclude this talk by presenting calibration results to market data. This is joint work with Z. Grbac, J. Schoenmakers and D. Skovmand. Date: Wednesday, September 25, 2013Time: 5:00 pmLocation: Wean Hall 7201Submitted by:  Shreve
