Research Interests

HIRES_26

My research is at the intersection of labor and innovation aimed at understanding the way we work – how innovation impacts pay and the role that teamwork plays in the invention process.

I’m primarily interested in the rise of social, creative, and stem skills and its impact on wages and invention. In my previous work, I researched three topics: i. the impact of automation on inequality across Europe, ii. the role of teamwork (it’s impact on patenting throughout the life course), and iii. the importance of social & communication skills in knowledge diverse industries.

Currently, I am an Assistant Professor of Economics at Pace University in New York, NY.

About Mary Kaltenberg

I am currently an Assistant Professor of Economics at Pace University. Previously, I was a post-doctoral fellow at Brandeis University with Adam Jaffe and Margie Lachman working on the inventor creative life cycle with patent data. I did my PhD at UNU-MERIT (Maastricht University), Maastricht, The Netherlands. My doctoral advisors were Bart Verspagen (UNU-MERIT), Neil Foster-McGregor (UNU-MERIT) and Cesar Hidalgo at the Collective Learning group at the MIT Media Lab (now at the University of Toulouse). 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 (BA/MA program) .

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

The Knowledge Manager: Wage Premiums in Knowledge Diverse Industries

Larger industries are known to pay more, but are these premiums simply a reflection of industry size, or are they an expression of increased knowledge diversity? Firms operate much like a team – they coordinate a variety of tasks and specializations to produce a good or service. In order to improve productivity, firms will seek to improve the efficiency of a task. Some ways that firms can do this is adopting a new technology, reduce coordination costs, and hire effective communicators. Firms that have to manage a wide variety of knowledge specializations have higher coordination costs, and these costs are especially high for firms that combine knowledge that are relatively dissimilar from one another. Firms that hire individuals who are effective communicators can reduce their burdening coordination costs, and are therefore willing hire individuals who have more social skills at a higher wage premium. I test this theory at the industry level, where I can empirically observe varying degrees of specialization. I develop a novel way to approximate knowledge specialization using an occupation-industry network. This network allows me to capture the variety of specializations in and industry, and the relative knowledge base distance between two occupations. At the industry level, workers who have social and communication skills will sort to industries that have a higher diversity of knowledge because those industries are willing to pay a knowledge diversity premium to reduce their high coordination costs. My results show that workers in industries with higher knowledge diversity receive a wage premium, especially for jobs with social, communication and interpersonal skills.

Exporting Up: The Importance of Improving Technological Capabilities for Growth

What is the best way to measure technological capabilities? Over the past 15 years, technological capability indices have developed into two strains: aggregated capability indices and export based algorithms. We discuss the strength and weaknesses of using such measures and test at which point technological capabilities are important for low income nations to `catch-up’ with developed nations. We explore a variety of econometric estimation techniques including, random effect, fixed effect, Hausman-Taylor and GMM that compare three export based algorithms, economic complexity index, fitness and generalized fitness. Our results indicate that technological capabilities, measured with export based algorithms, contribute to economic growth for low income nations. However, we do not find conclusive evidence that these measures have an impact at all stages of the development process. We suggest that to understand how economic structures impact economic growth, future pathways of research should reevaluate how to measure complexity to include value added which is increasingly fragmented across global production chains, and to measure the complexity of service and knowledge based products which are becoming a pivotal part of economies across the world.

Teaching

Teaching Philosophy

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 clearly visible in theory alone, but also through application. Students also learn better when 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.
