Optimal price promotion in the presence of asymmetric reference-price effects by Fibich, Gadi, Gavious, Arieh, Lowengart, Oded

“…In this study we demonstrate how a reference price may affect the degree of price rigidity/flexibility. For this, we construct a model of reference-price…”

DIFFUSION OF NEW PRODUCTS WITH RECOVERING CONSUMERS by FIBICH, G.

“…We consider the diffusion of new products in the discrete Bass-SIR model, in which consumers who adopt the product can later "recover" and stop influencing…”

Numerical simulations of asymmetric first-price auctions by Fibich, Gadi, Gavish, Nir

“…The standard method for computing the equilibrium strategies of asymmetric first-price auctions is the backward-shooting method. In this study we show that the…”

Loss of physical reversibility in reversible systems by Sagiv, Amir, Ditkowski, Adi, Goodman, Roy H., Fibich, Gadi

“…A dynamical system is said to be reversible if, given an output, the input can always be recovered in a well-posed manner. Nevertheless, we argue that…”
