Undocumented migrant workers are among a group of marginalized stakeholders who are severely exploited at their workplace and across broader society. Despite recent scholarly discussions in marginalized stakeholder theory and migration studies, our understanding of how undocumented workers...

Prevailing methods for measuring sensitive outcomes confront researchers with an inherent bias-variance trade-off: direct questioning is prone to a sensitivity bias, while indirect methods such as list experiments are substantially less precise. We introduce the ballot-bag, a novel technique...
