摘要：Post-docs signal their ability to do science and teaching to get a tenure giving universities the
possibility of separating highly talented agents from the low talented ones. However
separating that means signalling effort for the highly talented becomes even more important in
a two-dimensional signalling case. This attracts notice to time constraints. Under weak
conditions separating equilibria do not exist if time constraints are binding. The existing
equilibria are more costly but without additional information compared to the one-
dimensional case. Considering this, the efficiency of the current two-dimensional academic
job market signalling can be improved by switching to a one-dimensional one.
