Trade-Related Intellectual Property Rights, North-South Trade, and Biological Diversity

In the Trade-Related Intellectual Property Rights (TRIPS) Agreement of GATT (1 January 1995) it was agreed to harmonise intellectual property rights (IPR) on an international level and to include the option for patent protection for all life forms such as plants and animals (Article 27 (3) b).

Is Child Like Parent? Educational Attainment and Ethnic Origin

A Mixed Approach and a Distribution-Free Multiple Imputation Technique for the Estimation of a Multivariate Probit Model with Missing Values

In the present paper a mixed generalized estimating/pseudo-score equations (GEPSE) approach together with a distribution-free multiple imputation technique is proposed for the estimation of regression and correlation structure parameters of multivariate probit models with missing values for an ordered categorical timeinvariant variable. Furthermore, a generalization of the squared trace correlation ...

Evaluation of a Pseudo-R2 Measure for Panel Probit Models

A simulation study designed to evaluate the pseudo-R2T proposed in an earlier paper by Spiess and Keller suggests that, for the models considered, this measure represents the goodness of fit not only of the systematic part, but also of the assumed correlation structure in binary panel probit models.

Education, Employment, and Gender Inequality amongst Couples: A Comparative Analysis of Britain and Germany
