Estimating Engel curves under unit and item nonresponse
2010
SUMMARY This paper estimates food Engel curves using data from the first wave of the Survey on Health, Aging and Retirement in Europe (SHARE). Our statistical model simultaneously takes into account selectivity due to unit and item nonresponse, endogeneity problems, and issues related to flexible specification of the relationship of interest. We estimate both parametric and semiparametric specifications of the model. The parametric specification assumes that the unobservables in the model follow a multivariate Gaussian distribution, while the semiparametric specification avoids distributional assumptions about the unobservables.

A complete system of Engel curves in the Spanish economy
2003
The main goal of this article is the estimation of the consumption–income relationship along with socio–economic factors using cross section data from the Spanish Household Expenditure Survey 1991. The data has been grouped according to exogenous criteria to avoid the problem of null expenditure. First, a non–linear system of equation is estimated, from which the linear form that best fits the used data is tested. Finally, income elasticities are calculated considering three alternative formulations depending on how an initial income increment is distributed among consumers. Income elasticities are shown for the whole income distribution
A Sample Selection Model for Unit and Item Nonresponse in Cross-Sectional Surveys
2007
We consider a general sample selection model where unit and item nonresponse simultaneously affect a regression relationship of interest, and both types of nonresponse are potentially correlated. We estimate both parametric and semiparametric specifications of the model. The parametric specification assumes that the errors in the latent regression equations follow a trivariate Gaussian distribution. The semiparametric specification avoids distributional assumptions about the underlying regression errors. In our empirical application, we estimate Engel curves for consumption expenditure using data from the first wave of SHARE (Survey on Health, Aging and Retirement in Europe).
Demographic and Economics Determinants of Differentiation of Consumption Model in Silesia in Poland in the Years 1994-2013
2016
The research presented in this article focuses on long-term changes in consumption patterns in Silesia, which covers three border provinces of Poland - Silesia, Opole Voivodship and Lower Silesia. The investigation concerns also identification of the most important factors determining differentiation of consumption patterns implemented by households in that region. Based on data of the Central Statistical Office in Warsaw coming from the panel research on households’ budgets in 2004-2013 there was conducted an econometric analysis of few characteristics of households (such as: the level and the main source of income, place of residence, age or educational level of reference person (leader o…
