Land prices with urban sprawl: a model for Spain The paper describes the agricultural land price to identify the explanatory variables of the recent cycle in Spain. The key variables in our panel data model are location and expected farm rents as fundamentals and the housing prices and increases...

This paper proposes a new method for estimating a structural model of labour supply in which hours of work depend on (log) wages and the wage rate is considered endogenous. The main innovation with respect to other related estimation procedures is that a nonparametric additive structure in the...

Microdata concerning consumer demand typically show considerable variation in real expenditures, but very little variation in prices. We propose a semiparametric strategy for the consumer demand problem in which expenditure share equations are estimated nonparametrically in the real expenditure...

The purpose of this paper is to model the interaction between the targets of the current CAP: environmental adaptation, subsidies and efficiency the of animal farming. To this end we first have to identify the production frontier and relative efficiency level for each animal oriented type of...

The paper presents a study of the generalized partially linear model including random effects in its linear part. We propose an estimator that combines likelihood approaches for mixed effects models, with kernel methods. Following the methodology of Härdle and co-workers, we introduce a test...

Imagine we have two different samples and are interested in doing semi- or non-parametric regression analysis in each of them, possibly on the same model. In this paper, we consider the problem of testing whether a specific covariate has different impacts on the regression curve in these two...

The study focuses on testing the hypothesis that the subsidy system of the Common Agricultural Reform in 1992 (CAP'92) drove to changes in farm efficiency towards the thereby claimed objectives. With sequential applications of semiparametric methods we succeed to identify the impact of the...
