    Do Rating Agencies Behave Defensively for Higher Risk Issuers?

    By: Samuel B. Bonsall IV, Kevin Koharki, Pepa Kraft, Karl A. Muller III and Anywhere Sikochi

    We examine whether rating agencies act defensively toward issuers with a higher likelihood of default. We find that agencies' qualitative soft rating adjustments are more accurate as issuers' default risk grows, as evidenced by the adjustments leading to lower Type I and Type II error rates and better prediction of default and default recovery losses. We also find that soft adjustments' relevance increases with issuers' default risk, as evidenced by the adjustments being more predictive of initial offering yields and leading to a greater market reaction to rating changes.

    The Irredeemability of the Past: Determinants of Reconciliation and Revenge in Post-Conflict Settings

    By: Kristen Kao, Kristin Fabbe and Michael Bang Petersen

    In the aftermath of violent conflict, identifying former enemy collaborators versus innocent bystanders forced to flee violence is difficult. In post-conflict settings, internally displaced persons (IDPs) risk becoming stigmatized and face difficulties reintegrating into society. This work considers the role of moral disapproval and future social value in processes of post-conflict reconciliation with stigmatized IDPs. We run two conjoint experiments embedded within a large-N face-to-face survey across three areas of Iraq (n=4,592) experiencing the return of stigmatized IDPs, many of whom are suspected of having collaborated with the Islamic State in Iraq and Syria (ISIS).

    Optimalen Capital

    By: Malcolm Baker, Elisabeth Kempf and Jonathan Wallen

    A new client portfolio manager at a quantitative investment management firm must explain why her firm, Optimalen Capital, has rebalanced a client portfolio with a set of trades that seem unintuitive. In particular, Optimalen has added to its position of Walmart (ticker = WMT) and reduced its position in Tesla (TSLA) despite the latter having a much higher forecast return. She also must compute breakeven returns for two other stocks, Exxon Mobil (XOM) and Duke Energy (DUK).

    Dena Almansoori at e&: Fostering Culture Change at a UAE Telco Transforming to a Global Techco

    By: Emily Truelove, Michelle Zhang and Alpana Thapar

    Dena Almansoori, the first female and one of the youngest members of the United Arab Emirates-based e&’s leadership team, joined in 2020 just before e& began a strategic transition from being a regional telecommunications company to becoming a global technology company. As the group’s chief HR officer, Almansoori had a key role to play in this transition. Her mandate was to build a culture that was a “magnet” for top global talent, such that e& would compete with the likes of Amazon and Google not only for customers, but employees too. Many deemed this to be a radically ambitious goal.

    Corporate Leaders Say They Are for Stakeholder Capitalism—But Which Version Exactly?: A Critical Look at Four Varieties

    By: Lynn S. Paine

    The past few years have seen an outpouring of articles and statements heralding the arrival of a new and more inclusive form of capitalism often called stakeholder capitalism. The new capitalism promises to strengthen companies, improve outcomes for their constituencies, produce better returns for long-term shareholders, and ultimately strengthen the economy and society as a whole. In line with the new ideology, corporate boards and business leaders are being urged to replace the shareholder-centered approach to governance that has guided their work for the past several decades and, instead, to adopt a multi-stakeholder approach. In speaking with hundreds of corporate directors, executives, investors, governance professionals, and academics over the years, I’ve found wide differences in how stakeholder capitalism is understood and what it is thought to require of companies and their leaders.

    Residential Battery Storage - Reshaping The Way We Do Electricity

    By: Christian Kaps and Serguei Netessine

    In this paper, we aim to understand when private households invest in rooftop solar installations and battery storage, and how these investment decisions affect their electricity usage patterns as well as the market structure overall. We answer three main research questions: 1) What drives customers to combine solar power with storage installations; 2) How does privately-owned storage change consumer autonomy and the grid provider business model, and how heterogeneous is this effect across the population; 3) What effects do subsidies have on investments, demands, and carbon emissions. We develop a structural estimation model of residential electricity usage, that allows us to estimate a household's hourly consumption preferences, and a non-financial utility the household has for using self-generated solar power over grid-procured electricity; we call this utility greenness valuation.

Open Source Software and Global Entrepreneurship

By: Nataliya Langburd Wright, Frank Nagle and Shane Greenstein
  • November 2023 |
  • Article |
  • Research Policy
This is the first study to consider the relationship between open source software (OSS) and entrepreneurship around the globe. This study measures whether country-level participation on the GitHub OSS platform affects the founding of innovative ventures, and where it does so, for what types of ventures. We estimate these effects using cross-country variation in new venture founding and OSS participation. We propose an approach using instrumental variables, and cannot reject a causal interpretation. The study finds that an increase in GitHub participation in a given country generates an increase in the number of new technology ventures within that country in the subsequent year. The evidence suggests this relationship is complementary to a country’s endowments, and does not substitute for them. In addition to this positive change in the rate of entrepreneurship, we also find a change in direction—OSS contributions lead to new ventures that are more mission- and global-oriented and are of a higher quality. Together, the results suggest that OSS can boost entrepreneurial activity, albeit with a human capital prerequisite. Finally, we consider the implications for policies that encourage OSS as a lever for stimulating entrepreneurial growth.

Health System Perspective on Cost for Delivering a Decision Aid for Prostate Cancer Using Time-Driven Activity-Based Costing

By: David R. Ho, Robert S. Kaplan, Jonathan Bergman, David F. Penson, Benjamin Waterman, Kristin C. Williams, Jefersson Villatoro, Lorna Kwan and Christopher S. Saigal
  • October 2023 |
  • Article |
  • Medical Care
Previsit decision aids (DAs) have been shown to improve decisional quality. But the cost to deploy a DA has not been previously estimated. We interviewed or observed relevant personnel at three institutions that had implemented DA programs for men with prostate cancer. We used time-driven activity-based costing to estimate cost. Total average costs (USD) per patient were $38 (UCLA), $60 (Olive View-UCLA), and $42 (Vanderbilt), respectively, with labor costs being the largest component. Electronic health record (EHR) integration streamlined DA delivery efficiency and produced substantial cost savings. DA use was also associated with shorter clinic visit length and high levels of decision quality.

CMA CGM: Reducing the Carbon Footprint of Container Shipping

By: Willy C. Shih
  • September 2023 |
  • Supplement |
  • Faculty Research
Marine transport is the most cost-effective way to move large volumes over long distances, and container shipping is the backbone of international trade in goods. Yet shipping contributed 3% of worldwide greenhouse gas emissions, and the deep-sea segment, which included long distance trade lanes such as Asia to Northern Europe and Asia to North America, warranted special focus because they accounted for 80% of maritime transport’s total emissions in 2019. New International Maritime Organization regulations that came into force in January 2023 mandated the annual calculation and grading of each ship of more than 5,000 deadweight tons. Vessels that received a grade of A, B, or C were compliant, while those graded D or E had time limits for getting back into compliance or removal from service. More significantly, the standards for grading required annual improvements in efficiency. This meant that a brand-new vessel built with the latest technology that was initially graded A could over time become graded E and no longer be legally operable if no upgrades were made. This is the supplementary spreadsheet for the case.

The Case Method

Introduced by HBS faculty to business education in 1925, the case method is a powerful interactive learning process that puts students in the shoes of a leader faced with a real-world management issue and challenges them to propose and justify a resolution.
Today, HBS remains an authority on teaching by the case method. The School is also the world’s leading case-writing institution, with HBS faculty members contributing hundreds of new cases to the management curriculum a year via the School’s unique case development and writing process.
