Special issue of California Management Review explores multi-sided platforms

A new special issue of California Management Review (CMR) explores the rise of multi-sided platforms—digital ecosystems like Amazon, Uber, Paypal and other marketplaces where buyers, sellers, or other users can connect or collaborate.

CMR’s summer 2022 issue includes two articles co-authored by Berkeley Haas Professor David J. Teece, the Thomas W. Tusher Professor in Global Business, and covers multi-sided platform applications in healthcare and mental health, big tech, and autonomous vehicles.

CMR is Berkeley Haas’s academic management journal that bridges the study and practice of management. 

Big jump in influence for the Haas School’s California Management Review, ranked among top journals

California Management Review (CMR)—the Haas School’s academic management journal—has for the second year in a row earned a big jump in a ranking of its academic influence, placing it as one of the most highly cited practitioner-oriented research journals in the world.

The journal earned a two-year impact factor of 11.7 in the 2021 Clarivate Journal Citation Reports, a substantial increase from 8.8 last year. That placed it at #9 in the business journal category and #10 in management.

CMR also earned a five-year impact factor of 12.2, up from 9.3 last year.

Clarivate’s journal impact factor is a gauge of academic influence among top social science journals. It’s based on how frequently a journal’s articles are cited by scholars who publish in a collection of top social science journals. CMR articles were cited 7,895 times in 2021.

“We have been able to increase CMR’s relevance by consistently attracting and publishing important and influential research,” said David Vogel, the journal’s editor and Berkeley Haas professor emeritus. “The strong upward trajectory of our impact factor also reflects our many efforts over the last several years to extend CMR’s reach through social media engagement, expanding outreach, diversifying into digital mediums, and developing new content such as our CMR Insights.”

Tips for perfectly confident leadership

A silhouetted figure leads a group

Confident people tend to excel—in business, athletics, politics, and other domains. Yet overconfidence can lead to risks that undermine leaders and their companies’ reputations. So, how much confidence is too much confidence?

“Prior research has suggested that there can be some interpersonal benefits of expressing confidence. But it has not explored the dilemmas and potential for hypocrisy created by following that guidance,” says Berkeley Haas Prof. Don Moore, author of Perfectly Confident: How to Calibrate Your Decisions Wisely.

In a new article for California Management Review titled “Perfectly Confident Leadership,” Moore calls into question the idea that overconfidence improves performance, and offers strategies on how to become a wise leader who is both confident and honest.

Confidence does not indicate skill

Often, people associate confidence with skill. But research has not shown a direct connection between the two, says Moore, who has studied confidence and overconfidence for twenty years. He mentions a study demonstrating that people with high confidence and low confidence performed the same level. Yet despite the outcomes, people expected the highly confident people to perform better than the less confident people. This shows that confidence does not necessarily indicate skill, but rather it leaves an impression to others that it does.

While being confident can make you appear highly qualified and help increase others’ faith in you as a leader, being too confident can be your downfall. “Overconfident leaders put themselves, their teams, and their organizations at risk,” says Moore, the Lorraine Tyson Mitchell Chair in Leadership.

Many leaders may feel pressure to stay positive, especially in a pandemic, and resort to lying about successes to both themselves and others. One leader in particular, Elizabeth Holmes, made confident claims about her company Theranos, stating that its product could conduct hundreds of blood tests with one drop of blood—ultimately an impossible task to complete. Many criticized her as she was unable to meet those claims, making it difficult for Theranos to come clean about. Holmes’ experience is one of the many examples that reflect the consequences of confidence without substance.

Emotion vs facts

On the other hand, Moore finds that arguments displaying the most confidence often win a debate. If the goal is to persuade others, anecdotal and emotional statements appeal to an audience, gaining more support than objective, statistical, and factual claims. Still, winning a debate is not the same as solving problems. Falling for leaders who demonstrate a persuasive character without substance can be detrimental for the future.

If confidence can mask the incompetence and deceptions of leaders, how can we know who to support and who to believe in? Moore highlights that persuasive talks are often expressed through ambiguous optimism and assertive behavior.  It’s important to clarify and test others’ claims, ultimately choosing the person who is most capable and truthful.

As Moore says, “well-calibrated confidence, consistent with the facts, is most useful for calibrating expectations and informing decisions.”

New paper highlights manipulation in 5G patent licensing

The value of competing 5G technology standards shouldn’t be judged by number of patents alone, according to new research by David Teece.

Whether its mobile phones or autonomous cars or telemedicine, 5G is a game-changer, enabling cellular connections up to 100 times faster than 4G. Unfortunately, not all 5G implementations are alike: 5G technology portfolios are easily manipulated by patent holders, and determining which set of technologies and standards are most viable is not always straightforward.

That’s according to Berkeley Haas Prof. David Teece, who examined the problem of 5G patents in a new article for California Management Review titled, “Technological Leadership and 5G Patent Portfolios: Guiding Strategic Policy and Licensing Decisions.” Teece, the Thomas W. Tusher Professor in Global Business and director of the Tusher Initiative of Intangible Assets, highlights the flaws of the patent licensing system and the use of patent counts as an indicator of a technology’s value.

Patent licensing systems

When 5G developers patent their technology, they work with standard development organizations (SDOs) that in turn work with the 3rd Generation Partnership Project (3GPP) to make sure that the patents are commercially viable and meet the standardized elements for foundational technologies. Once the patent is licensed, 3GPP and these developers gain their profits from patent licensing fees and royalty payments which are determined by the fair, reasonable, and nondiscriminatory (FRAND) criteria.

Teece observed that under this licensing system, policing unlicensed use of patent data is often complex and difficult. That means that while these patents may be protected legally, they may not be protected practically. Moreover, just because a license is available does not mean royalties will be paid: The SDOs that patent-developers work with only provide the FRAND framework, but do not assist in developing an official licensing program. Teece suggests that patent owners must be willing to develop a licensing program that users must sign up for, and courts must be willing to charge patent infringers. These two actions may help prevent unlicensed users from getting away with not paying royalities.

Manipulation of patent counts

Another problem lies in the way that many companies determine which patents to license. It is tempting to look at the number of patents generated as an indicator of their quality, but quantity does not equal quality. “Patent counts are misleading proxies for technological contribution and leadership,” says Teece. “When well-respected media outlets like the Wall Street Journal and the Financial Times trumpet the patent rankings of companies and countries as proxies for patent value and technological leadership, with minimal if any qualification, it reinforces widespread ignorance about the utility of patent statistics.”

Patent counts can be deceiving and because they are likely biased, he says. For example, one country could hold the most patents, but others may be running the development and deployment services for 5G technology. On another note, the line between patents described as essential and patents simply declared as essential can be ambiguous. This makes patent counting inaccurate and invalid.

More importantly, Teece found that “the patent process is strategically manipulated by some countries and some companies.” For example, as China races to match the success of Western economies, it now owns about 36% of essential 5G patents. They may be partly due to China’s government subsidizing many of the patenting processes, however. Companies also have this same motivation for obtaining license control. In the past, higher patent counts were due to certain companies’ efforts to gain leverage in license negotiations.

With patent counts being easily manipulated, Teece described five key metrics used to understand patent data. Family counts and the number of technical contributions to standard bodies are found to be easy to manipulate and are not meaningful indicators of technological value, he says. On the other hand, forward-citation counts, the number of independent claims, and geographic coverage are difficult to manipulate, but are still not perfect in judging the value of a patent.  For example, forward-citation counts do not always reflect commercial significance.

After understanding how patent data is analyzed, Teece lays out methods to for properly assessing leadership in 5G technology. These include performing a patent-by-patent analysis of leading patents, looking at comparable licenses (with running royalty licenses as the most reliable indicator of royalty rates), and utilizing aggregate market-observed choice data to calculate the profit impact of patented technologies.

“Manipulation happens all too often,” Teece says. Though some of the alternative methods to determine technological value may be costly, these steps can help make vast improvements to the future of wireless technology development and use, he argues
