In this note we use unique data from Bar-Ilan University, over a period of four years (2005-2008), to estimate simultaneous equations with regard to the relationship between publications and teaching loads. The study shows that students studying for a bachelor's degree are a liability while PhD students are an asset in terms of publications. Those studying for a master's degree may be a liability or an asset depending on the department characteristics. Increasing the number of faculty members increases publications however it may not increase the publications per capita and is department specific.
