Nonparametric estimation of nonadditive hedonic models

Working Paper

We analyze equilibria in hedonic economies and study conditions that lead to identification of structural preference parameters in hedonic economies with both additive and nonadditive marginal utility and marginal product functions.

Estimating a semi-parametric duration model without specifying heterogeneity

Journal article

This paper is concerned with the practical problem of conducting inference in a vector time series setting when the data is unbalanced or incomplete. In this case, one can work only with the common sample, to which a standard HAC/bootstrap theory applies, but at the expense of throwing away data and perhaps losing effciency. An alternative is to use some sort of imputation method, but this requires additional modelling assumptions, which we would rather avoid.1 We show how the sampling theory changes and how to modify the resampling algorithms to accommodate the problem of missing data.

GEL Criteria for Moment Condition Models

Working Paper

GEL methods which generalize and extend previous contributions are defined and analysed for moment condition models specified in terms of weakly dependent data.
