What is the impact of male and female alumni speaker interventions in introductory microeconomics courses on student interest in economics? Using student-level transcript data, we estimate the effect of speakers on future course-taking in models which use untreated lectures as control groups,...

Economics is among the most popular undergraduate majors. However, even at the best research universities and liberal arts colleges men outnumber women by two to one, and overall there are about 2.5 males to every female economics major. The Undergraduate Women in Economics (UWE) Challenge was...

After decades of rising global economic integration, the world economy is now fragmenting. To measure this phenomenon, we introduce an index of geopolitical fragmentation derived from various empirical indicators. This index is developed using a flexible dynamic factor model with time-varying...

We propose a general simulation-based procedure for estimating quality of approximate policies in heterogeneous-agent equilibrium models, which allows to verify that such approximate solutions describe a near-rational equilibrium. Our procedure endows agents with superior knowledge of the future...

We study the impact of the Covid-19 pandemic on Euro Area inflation and how it compares to the experiences of other countries, such as the United States, over the two-year period 2020-21. Our model-based calibration exercises deliver four key results: 1) Compositional effects - the switch from...

This paper builds on Baqaee and Farhi (2022) and di Giovanni et al. (2022) to quantify the contribution of fiscal policy on U.S. inflation over the Dec-2019 to June-2022 period. Model calibrations show that aggregate demand shocks explain roughly two-thirds of total model-based inflation, and...

Using dissertation research topics found in the EconLit database and large-scale algorithmic methods that identify author demographics based on names, we explore the link between race and ethnicity and fields of economic research. We find that underrepresented racial and ethnic minority (URM)...

Using the EconLit dissertation database and large-scale algorithmic methods that identify author demographics from names, we investigate the connection between the gender of economics dissertators and dissertation topics. Despite stagnation in the share of women among economics Ph.D.s in recent...

Large language models (LLMs) such as ChatGPT have the potential to revolutionize research in economics and other disciplines. I describe 25 use cases along six domains in which LLMs are starting to become useful as both research assistants and tutors: ideation, writing, background research, data...

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...
