Literature on Digit Ratio is rapidly growing in Economics. Quite surprisingly we observe that there is no consensus about how to make an accurate measurement in such a delicate task. Along this brief document we offer some concise guidance of how to scan the hands using digital scanners and...

Economic experiments report that individuals perform better under a piece rate payment scheme in comparison to a fixed payment scheme. The reason is straightforward: incentives motivate people, and without incentives they decrease their effort. Yet women are prone to choose a fixed payment over...
