Using detailed administrative data that allow us to hold gender, education, productivity, timeliness, and work quality constant, we document that minority patent examiners at the U.S. patent office face substantial glass ceilings and pay gaps. The promotion gap relative to White examiners...

The Financial Risk Meter (FRM) is an established mechanism that, based on conditional Value at Risk (VaR) ideas, yields insight into the dynamics of network risk. Originally, the FRM has been composed via Lasso based quantile regression, but we here extend it by incorporating the idea of...

Following the death of a star, do coauthors experience a uniform decline in their productivity? Prior work informs us that the death of a star negatively influences coauthors’ productivity. In this study, I extend this work and argue that the characteristics of coauthors’ collaboration...

This paper provides causal evidence of local innovation spillovers, i.e. innovation by one firm fostering innovation by neighboring firms.

In the absence of first-best climate policy, energy efficiency has figured prominently among strategies to reduce carbon emissions. One of the most sought-after green certification in the building sector is the internationally recognized Leadership in Energy & Environmental Design (LEED). This...

We develop efficiency estimates for the production, implementation and diffusion of artificial intelligence (AI) services. We use a variety of data measuring factors relating to AI input and output. We start by constructing a set of nine different AI efficiency measures using non-parametric...
