Research Interests

My research is at the intersection of labor and innovation aimed at understanding the impact of the structure of work due to the current wave of innovation (ICT revolution, digital innovation, the internet of things, automation, AI, etc.). I’m interested in 2 main themes within this topic:

1. The way we do work

This has been discussed at length in regards to the replacement of routine work, rise of social and stem skills, and within the innovation and management/organization fields, the importance of teamwork. In my previous work, I have been interested in the role of teamwork (it’s impact in conjunction with age on lifetime patenting) and skills (particularly the importance of knowledge managers and social & communication skills).

2. How work is structured

Having a single employer is still the predominant form of work, but the rise of new online labor markets has lead way to a new class of work (often called the gig economy) of which many labor institutions are unprepared to handle.

How are new types of work affecting wages? With the rise of the gig economy, income can now come from a variety of sources, whether that be platform work (ie Mechanical Turk), renting out possessions (Homes via airbnb, cars via Turo) or providing services (Thumbtack, Etsy, Lyft). Work has become decentralized in these markets with employers no longer providing the same benefits or pay structure as those in more centralized firm organization structures. Has this new structure impacted inequality? Is there biasedness in hiring within online labor markets? What is the responsibility of the firm to the employee? Under which labor institutional settings can workers be best protected considering the changing role of the firm (ie in the us context of providing retirement benefit options and healthcare)? How do we consider contracts for this new type of work and what rights do these individuals have?

I also have worked on other topics:

  • Structural change (economic complexity & development)
  • Skills & education demand in Brazil
  • Inequality across Europe
  • Mapping inequality in Brazil


Q: If you had to convince a young adult why they should study economics, what would you tell them?

If they are curious about the world then study economics – become a worldy philosopher as Robert Heilbroner coined it.


About Mary Kaltenberg

Profile Pic

I am currently a post-doctoral fellow at Brandeis University with Adam Jaffe and Margie Lachman working on the inventor life cycle with patent data. I was a PhD Fellow at UNU-MERIT, Maastricht, The Netherlands. My doctoral advisors were Bart Verspagen at UNU-MERIT, Neil Foster-McGregor at UNU-MERIT and Cesar Hidalgo at the Collective Learning group at the MIT Media Lab. In 2016, I was a visiting student and research assistant at the MIT Media Lab.

Previously, I worked at UNICEF on resource mobilization and research on accessibility to health care. I received my masters and bachelors degree in economics from The New School for Social Research in New York City.

Check out my Github for code and data from previous papers (currently updating), and code for tutorials for previously taught short courses.

Teaching Philosophy

The goal of economics is to make sense of the social world around us. I believe the best way to teach economics is through applied real world examples in an active environment. My pedagogical approach is to challenge students by asking questions and utilize classroom activities that reiterate the learning objective. This is especially important when teaching econometrics or statistics – the power of these tools is not visible in theory, but through application. Students also learn better when learning objectives are repeated in different ways – data collecting at the lecture, interactive websites, short videos at home, writing reports and problems sets. Learning is best applied in a community of active and engaged students. My goal as a teacher is to foster this kind of environment.
