We show that contrary to conventional wisdom intergenerational family transfers dominate fiscal policies as a remedy to the dynamic inefficiency arising in a Diamond (1965, American Economic Review) economy with logarithmic utility and Cobb-Douglas technology. Using the demonstration-effect...

In view of solving nonsmooth and nonconvex problems involving complex constraints (like standard NLP problems), we study general maximization-minimization procedures produced by families of strongly convex sub-problems. Using techniques from semi-algebraic geometry and variational analysis -in...

The paper determines how the value-added created by an organic label is shared in a vertical chain among manufacturers and retailers. Using purchase data on the French fluid milk sector, we develop a structural econometric model of demand and supply that takes into account the bargaining power...
