Research and development (R & D) competition is standard, and it heavily affects patent values. This study captures R&D competition's effects on patent values using game-theory approaches. Cost-reduction patent values increase with technology level and decrease with the competition. Technology...

Researchers are often interested in testing for measurement invariance with respect to an ordinal auxiliary variable such as age group, income class, or school grade. In a factor-analytic context, these tests are traditionally carried out via a likelihood ratio test statistic comparing a model...
