This paper studies optimal decision rules, including estimators and tests, for weakly identified GMM models. We derive the limit experiment GMM, propose a theoretically?motivated class of priors which give rise to quasi?Bayes rules as limiting case. Together with results in previous literature, this establishes desirable properties approach regardless model identification status, we recommend s...

We released genetically modified Pseudomonas putida WCS358r into the rhizospheres of wheat plants. The two genetically modified derivatives, genetically modified microorganism (GMM) 2 and GMM 8, carried the phz biosynthetic gene locus of strain P. fluorescens 2-79 and constitutively produced the antifungal compound phenazine-1-carboxylic acid (PCA). In the springs of 1997 and 1998 we sowed whea...
