Depression as a major mental illness among older adults has attracted a lot of research attention. However, the problem of sample selection, inevitable in most health surveys, has been largely ignored. To fill in this gap, this paper formally models selection into the sample jointly with a...

Leading papers in a journal’s issue attract, on average, more citations than those that follow. It is, however, difficult to assess whether they are of better quality (as is often suggested), or whether this happens just because they appear first in an issue. We make use of a natural...

This paper studies correlation in discounted infinitely repeated games with public monitoring. Two extensions of the perfect public equilibrium are proposed: the public correlated equilibrium, where a correlation device sends private correlated messages to the players at the beginning of each...
