      Lyssiotou, Panayiota Flori; Pashardes, Panos; Stengos, Thanasis (2002)
      An additive partially linear regression model is used to estimate non-parametrically the effects of total expenditure and age in the context of Engel curves and to investigate the specification and welfare interpretation ...

      Demographic versus expenditure flexibility in Engel curves 

      Lyssiotou, Panayiota Flori; Pashardes, Panos; Stengos, Thanasis (2008)
      We consider the effects of demographic and expenditure variables on consumer demand in a system of Engel curves using a smooth coefficient semiparametric model where the expenditure effects on the budget shares vary ...

      On estimating the cost of characteristics indices from consumer demand analysis 

      Lyssiotou, Panayiota Flori (2003)
      We examine the information content of relative equivalence scales using a multiperiod framework and argue that in the absence of Independence of Base (IB) these scales can be uniquely identified from demand analysis only ...
