Testing the rank of Engel curves with endogenous expenditure
(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 ...
Comparing the true cost of living indices of demographically different households
(2004)
The comparison of true cost of living indices between demographically different households (relative equivalence scale) is argued to be sensitive to the way demographic characteristics enter demand analysis. In particular, ...
Age effects on consumer demand: An additive partially linear regression model
(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 ...
Nesting quadratic logarithmic demand systems
(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 ...
Estimates of the black economy based on consumer demand approaches
(2004)
We propose a consumer demand system approach to estimating the size of the black economy where alternative hypotheses affecting the empirical results can be tested in a nested framework. This approach allows for the ...
Hedonic Price Analysis and Selectivity Bias: Water Salinity and Demand for Land
(2003)
Hedonic valuation of quality attributes can be misleading when the assumption that these attributes are exogenous to sample selection is violated. This paper considers the simultaneity between hedonic valuation and sample ...
