We study whether student-advisor gender and race composition matters for publication productivity of Ph.D. students in South Africa. We consider all Ph.D. students in STEM graduating between 2000 and 2014, after the recent systematic introduction of doctoral programs in this country. We...

We examine friendships and study partnerships among university students over several years. At the aggregate level, connections increase over time, but homophily on gender and ethnicity is relatively constant across time, university residences, and different network layers. At the individual...

We examine the dynamics of a country's growth, consumption, and sovereign debt, assuming that the government is myopic and wants to maximize short-term, self-interested spending. Surprisingly, government myopia can increase a country's access to external borrowing. In turn, access to borrowing...

The scholarly impact of academic research matters for academic promotions, influence, relevance to public policy, and others. Focusing on writing style in top-level professional journals, we examine how it changes with age, and how stylistic differences and age affect impact. As top-level...

Using data describing all "Top 5" economics journal publications from 1969-2018, we examine what determines which authors produce less as they age and which retire earlier. Sub-field has no impact on the rate of production, but interacts with it to alter retirement probabilities. A positive,...

We study how conflicts of interest (CoI)--defined as financial, professional, or ideological stakes held by authors--affect perceived credibility in economics research. Using a randomized controlled survey of both economists and a representative sample of the U.S. public, we find that the...

This study examines publications in three leading general economics journals from the 1960s through the 2020s, considering levels and trends in the demographics of authors, methodologies of the studies, and patterns of co-authorship. The average age of authors has increased nearly steadily;...

This paper presents a framework to standardize crowd-sourced computational reproductions in economics through the Social Science Reproduction Platform (SSRP). The approach address four main challenges for computational reproductions: a lack of standardization, aggregation issues, existing...

The adoption of new ideas is critical for realizing their full potential and for advancing the knowledge frontier but it involves analyzing innovators, potential adopters, and the networks that connect them. This paper applies natural language processing, network analysis, and a novel fixed...
