I am an assistant professor of Organizational Behavior Area at the Desautels School of Management at McGill University. I am broadly interested in patterns of employment and inequality in the United States and other developed countries. In recent years my research has focused on broad changes in employment patterns in the United States since the 1970s, in particular the growth in employment instability. While it seems obvious that workers are changing employers and careers more frequently than in the past, empirical evidence of this trend has been surprisingly weak. My research identifies several sources of these weak results and demonstrates that the growth in employment instability is stronger than the original empirical studies suggested. Future research will explore similar trends in employment instability in other developed countries.
