Research Finds Digital Music Streaming Consumption Dropped as a Result of Covid-19 and Lockdowns
Decline in human mobility has stunning consequences for content streaming
The Covid-19 pandemic and lockdowns significantly reduced the consumption of audio music streaming in many countries as people turned to video platforms. On average, audio music consumption decreased by 12.5% after the World Health Organization’s (WHO) pandemic declaration in March 2020.
Music streaming services were an unlikely area hit hard by the Covid-19 pandemic. New research in Marketing Science found that the drop in people’s mobility during the pandemic significantly reduced the consumption of audio music streaming. Instead, people turned more to video platforms.
“On average, audio music consumption decreased by more than 12% after the World Health Organization’s (WHO) pandemic declaration on March 11, 2020. As a result, during the pandemic, Spotify lost 838 million dollars of revenue in the first three quarters of 2020,” said Jaeung Sim, a PhD candidate in management engineering at KAIST and one of the authors of the research study on this phenomenon. “Our results showed that human mobility plays a much larger role in the audio consumption of music than previously thought.”
The study, “Frontiers: Virus Shook the Streaming Star: Estimating the Covid-19 Impact on Music Consumption,” conducted by Sim and Professor Daegon Cho of KAIST, Youngdeok Hwang of City University of New York, and Rahul Telang of Carnegie Mellon University, looked at online music streaming data for top songs for two years in 60 countries, as well as Covid-19 cases, lockdown statistics, and daily mobility data, to determine the nature of the changes.
The study showed how the pandemic adversely impacted music streaming services despite the common expectation that the pandemic would universally benefit online medias platforms. This implies that the substantially changing media consumption environment can place streaming music in fiercer competition with other media forms that offer more dynamic and vivid experiences to consumers.
The researchers found that music consumption through video platforms was positively associated with the severity of Covid-19, lockdown policies, and time spent at home.

Professor Jihee Kim Wins the Lucas Prize for Her Income Inequality Theory
Professor Jihee Kim from the School of Business and Technology Management at KAIST was announced as one of two winners of the 2021 Robert E. Lucas Jr. Prize. Professor Kim was recognized for having provided an empirical analysis on engines of income growth, sources of income inequality, and their rich interplay in her paper published in the Journal of Political Economy (JPE) in October 2018. The co-author of this study, Professor Charles I. Jones at Stanford University, was honored to be another awardee of this year’s Lucas Prize.
The Robert E. Lucas Jr. Prize, simply known as the Lucas Prize, is awarded biannually for the most interesting paper in the area of Dynamic Economics published in the leading economics journal JPE in the preceding two years. The prize was established in 2016 in celebration of the 1995 Nobel Prize in Economics Laureate Dr. Lucas’s seminal contributions to economics. The two former prizes were presented in 2019 and 2017 respectively.
Professor Kim and Professor Jones, in their award-winning paper titled 'A Schumpeterian Model of Top Income Inequality', observed that top income inequality was relatively low and stable between 1960 and 1980, but then rose sharply in some countries, including the United States and the United Kingdom.
The authors focused on entrepreneurial activities and the resulting income as the driving force of income inequality. They assumed that the forces that increased the efforts of fast-growing entrepreneurs to improve their products or increased productivity of their efforts could increase income inequality. On the other hand, the forces that enhanced creative destruction or that raised the rate at which high-growth entrepreneurs lost that status could decrease income inequality, according to the authors’ theory.
Professor Kim explained, “Various economic forces due to globalization, the advancement in AI and IT technologies, taxes, and policies related to innovation blocking may explain the varied patterns in income inequality.”
“Through follow-up research, I will continue developing economic theory models that can analyze the impact of changes such as income tax rates and salary negotiations on income inequality,” she added.
Professor Kim received her bachelor’s degree from the KAIST School of Computing in 2005 and pursued her graduates studies at Stanford University, acquiring a master’s degree in economics in 2011 and a doctoral degree in management science and engineering in 2013.

Prof. Jae-Kyu Lee Campaigns on "Bright Internet" Worldwide
Professor Jae-Kyu Lee (pictured on the right) from the College of Business at KAIST is one step closer to fulfilling his dream of achieving the “Bright Internet,” a campaign that he first proposed as he became the president of the Association for Information Systems (AIS) in June 2015.
On December 12, 2015, Professor Lee signed a memorandum of understanding (MOU) at a convention center in Fort Worth, Texas, between the AIS and the International Telecommunication Union (ITU)—a specialized agency of the United Nations that is responsible for issues related to information and communication technologies—on a collaborative research and development program to make the Internet safer for everyone.
The MOU pursues building a trusted international information and communication technology (ICT) infrastructure by proposing telecommunication policies, developing international standards, and organizing interdisciplinary conferences.
The Bright Internet is an initiative to protect online users from cyber terrors, privacy breaches, and cyber-crimes. Further, it involves putting accountability to those who initiate or deliver cyber threats, thereby eliminating the possible source of Internet related crimes.
Following the MOU agreement, Prof. Lee delivered a speech on his campaign at the 2015 International Conference on Information Systems and received positive responses from the audience.
The Bright Internet campaign has been selected as visions of various ICT organizations worldwide including the Korea Society of Management Information System and the International Federation of Information Processing. KAIST and Tsinghua University in China adopted it as an academic topic for research and teaching.
Prof. Lee claimed that the Internet should be used in a manner based on the values of trust, ethics, and decorum. He further noted that it is important to build Internet environments that not only protect individuals from cyber threats or attacks, but also hold those who commit online crimes accountable for their actions.

Professor Jae Kyu Lee Appointed the President of Association for Information Systems
Chair Professor Jae Kyu Lee of KAIST’s College of Business was appointed the President of Association for Information Systems (AIS) on July 1, 2015. Professor Lee will serve a one-year term, which will end in June 2016. With four thousand members researching information systems from 90 different nations, AIS is the largest academic society in the fields of information system and business process engineering.
Professor Lee has proposed his idea of “the Bright Internet” as the official vision of AIS. Employing this vision, AIS will create technology and systems, as well as sponsor international cooperation to solve fundamental issues of the Internet including concerns over hacking and cyber-related crimes.
The extent of damage from cyber-related crimes grows each year. Every day, 56 billion junk emails are sent to computers which are hacked and become “zombie” computers. The social cost of such crimes is estimated to be 400 billion US dollars annually.
Based on "the Bright Internet," AIS will build a preventative Internet security system by adopting ground rules that make attackers responsible for the damages from such crimes. The system will also modify technology and other systems to minimize privacy infringement while maintaining security. Finally, the Bright Internet proposes to adopt an international standard for this security system through collaboration with the International Telecommunications Union (ITU).
Professor Lee said, “The vision of the Bright Internet started from an awareness that we needed to resolve issues such as Internet addiction, indiscriminate media exposure, and verbal violence. This vision developed by the experts from all around the world will not only bring a revolution of a reliable Internet platform to a global scale but also reshape the Korean Internet platform.”

Professor Jae-Kyu Lee's Memoir "Knowledge and Beyond"
Professor Jae-Kyu Lee of KAIST’s College of Business has recently published a book called Knowledge and Beyond (available only in Korean). It deals with selected aspects of science and the world around us.
In Knowledge and Beyond, he expounds on his understanding of science, business, life, and religion. In part autobiographical, he describes his thirty-year career and his interaction with his past students who are now leading scientists and scholars in Korea, and offers some advice on how to better treasure life. Professor Lee also recounts his own life: his childhood, growing up and maturing with his mates, love at first sight of and his unconditional love towards his wife.
With respect to science, he talks about the origin of knowledge and ways to find solutions to questions that seem almost impossible to answer and offers a few aphorisms, such as: “studying is more like a marathon, not a boxing match;” “do not predict, but plan your future” and “learn by head in class, learn by heart in life.”
Knowledge and Beyond is a must read for those who have become exhausted by today’s competitive world, reminding readers of their life goals and paths.
Professor Lee said, “I wrote this book for the young to share the true meaning of life over plain knowledge. You can never find out the true meaning of life unless you combine simple and spiritual knowledge, and I hope this book helps in showing a way to achieve it.”
Professor Lee has taught at KAIST since 1985, and is currently the Dean of KAIST's Business College. He was formerly the Dean of KAIST College of Management, Director of KAIST EEWS (energy, environment, water, and sustainability) and the Vice Provost of the Singapore Management University’s School of Information Systems. He was also the President of The Korea Society of Management Information Systems and the President of Korea Intelligent Information System Society.
