This paper studies nonparametric estimation of conditional moment models in which the residual functions could be nonsmooth with respect to the unknown functions of endogenous variables. It is a problem of nonparametric nonlinear instrumental variables (IV) estimation, and a difficult nonlinear...

We consider testing for correct specification of a nonparametric instrumental variable regression. In this ill-posed inverse problem setting, the test statistic is based on the empirical minimum distance criterion corresponding to the conditional moment restriction evaluated with a Tikhonov...

We study the asymptotic distribution of Tikhonov Regularized estimation of quantile structural effects implied by a nonseparable model. The nonparametric instrumental variable estimator is based on a minimum distance principle. We show that the minimum distance problem without regularization is...

This paper considers the shape invariant modelling approach in semiparametric regression estimation. Nonparametric functions of similar shape are linked by parametric transformations with unknown parameters. A computationally convenient estimation procedure is suggested. √N- consistency of the...

Berkson errors are commonplace in empirical microeconomics and occur whenever we observe an average in a specified group rather than the true individual value. In consumer demand this form of measurement error is present because the price an individual pays is often measured by the average price...

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 of the age effects in parametric models of consumer behaviour. Empirical...

This paper examines the relationship between family stressors and subsequent financial behavior of young individuals in Croatia. Previous research indicates that family stressors are associated with increased levels of financial stress, resulting in impulsive purchases, risky financial behavior,...

This paper studies the impact of remittances on the savings behaviour of rural households in China, using a cross-sectional survey. Allowing for endogeneity and left-censoring of remittances, we find that the marginal propensity to save out of remittances is well below half of that out of other...

Earlier literature has investigated the drop in household consumption upon retirement of the head of the household, the so-called "retirement consumption puzzle". Here, we expand on these studies by considering also retirement of the wife, thus distinguishing households in which the wife is a...

This study examines, using quantile regression, the linkage between food security andefforts to enhance smallholder coffee producer incomes in Rwanda. Even though in Rwanda smallholder coffee producer incomes have increased, inhabitants these areas still experience stunting and wasting. This...
