      Nesting quadratic logarithmic demand systems 

      Lyssiotou, Panayiota Flori; Pashardes, Panos; Stengos, Thanasis (2002)
      We propose a new generalised rank-3 demand system which nests all known (and new) rank-3 and rank-2 demand systems derived from the Quadratic Logarithmic (QL) cost function. We investigate its statistical adequacy against ...

      Testing the rank of Engel curves with endogenous expenditure 

      Lyssiotou, Panayiota Flori; Pashardes, Panos; Stengos, Thanasis (1999)
      We find that the endogeneity of consumer expenditure tends to increase the estimated rank of Engel curves. This result, based on nonparametric procedure, is in line with previous results obtained in the context of parametric ...
