We investigate the causes and consequences of the aging of the scientific workforce. Using novel data on the population of US chemistry faculty members over fifty years, we find that the secular increase in the age of the academic workforce has been mainly driven by the slowdown in faculty...

We investigate whether excessively optimistic beliefs may play a role in the persistent demand for doctoral and post-doctoral training in science. We elicit the beliefs and career preferences of doctoral students through a novel survey and randomize the provision of structured information on the...

The advancement of the knowledge frontier is crucial for technological innovation and human progress. Using novel data from the setting of mathematics, this paper establishes two results. First, we document that individuals who demonstrate exceptional talent in their teenage years have an...

We estimate the career and location preferences of students in U.S. doctoral programs in a major STEM field – chemistry. Our analysis is based on novel survey conducted in 2017 of 1,605 current Chemistry doctoral students enrolled in the top 54 U.S. research intensive universities. First, we...

This paper studies the impact of U.S. immigration barriers on global knowledge production. We present four key findings. First, among Nobel Prize winners and Fields Medalists, migrants to the U.S. play a central role in the global knowledge network-representing 20-33% of the frontier knowledge...

I study how patents affect firm success (initial public offering or acquisition at a high price) in a sample of 2,191 U.S. startups applying for patent protection in the 24 months following their first round of venture capital funding. I observe both successful and unsuccessful patent...
