During the research for a recently-submitted paper, I decided to investigate the rising importance of graduate employability as a concern for universities (and the wider society). As an indicator of this trend I searched Google Scholar for articles with “graduate” and “employability” in the title – the results are shown in the chart below.
The increase in papers on graduate employability is striking, but probably not a surprise. Having done this research, however, I elected not to include the data in the paper. Why? My main concern was uncertainty about appropriate controls for the fact that there has been a general increase in information (specifically academic literature) during the same period. I was therefore uncomfortable about the dangers of over-interpretation.
Should I have worried? Is it a valid observation? What could serve as a legitimate control? Any thoughts gratefully received.
