Simulation models may have many parameters and input variables (together called factors), while only a few factors are really important (parsimony principle). For such models this paper presents an effective and efficient screening technique to identify and estimate those important factors. The...

We experimentally investigate the development of voluntary transfers in an overlapping generations environment. By varying the information conditions of the game, we study whether the development of transfers is related to the possibility of future generations to monitor and reciprocate...
