The literature on stochastic programming typically restricts attention to problems that fulfill constraint qualifications. estimation and inference under partial identification frequently the geometry of identified sets with diverse high-level assumptions. These superficially appear be different approaches closely related problems. We extensively analyze their relation. Among other things, we s...

Regular use of that vehicle requires, however, some constraint qualification . Yet many economists go easy on the mathematics issue. Conversely, few mathematicians elaborate economics context.
