The paper examines in the laboratory how risk-taking situations are affected by the conditions of observing other's choices (observer) and being observed by others (source). By extending Yechiam et al.'s (2008) experimental design to the domain of gains we find that observers are more probable...

This paper addresses two questions about the morality of warfare: (1) how much risk must soldiers take to minimize unintended civilian casualties caused by their own actions (“collateral damage”), and (2) whether it is the same for the enemy's civilians as for one's own. The questions take...

Here's why. (1) The HP filter produces series with spurious dynamic relations that have no basis in the underlying data-generating process. (2) Filtered values at the end of the sample are very different from those in the middle, and are also characterized by spurious dynamics. (3) A statistical...
