• HBS Book

This book offers a compelling reassessment and defense of purpose as a management ethos, documenting the vast performance gains and social benefits that become possible when firms manage to get purpose right. Few business topics have aroused more skepticism in recent years than the notion of corporate purpose, and for good reason. Too many companies deploy purpose, or a reason for being, as a promotional vehicle to make themselves feel virtuous and to look good to the outside world. Some have only foggy ideas about what purpose is and conflate it with strategy and other concepts like “mission,” “vision,” and “values.” Even well-intentioned leaders don’t understand purpose’s full potential and engage half-heartedly and superficially with it.

The authors analyzed data from multiple large-scale randomized experiments on LinkedIn’s People You May Know algorithm, which recommends new connections to LinkedIn members, to test the extent to which weak ties increased job mobility in the world’s largest professional social network. The experiments randomly varied the prevalence of weak ties in the networks of over 20 million people over a 5-year period, during which 2 billion new ties and 600,000 new jobs were created. The results provided experimental causal evidence supporting the strength of weak ties and suggested three revisions to the theory.

• Social Enterprise Initiative

In 2021, the HBS Impact Investment Fund student team had found a promising potential investment in Southwick Social Ventures (SSV), a worker and management-owned trouser manufacturer. With a 100% immigrant workforce, the co-operative was focused on reviving manufacturing in Lowell, Massachusetts, a city that was once an economic hub but had witnessed many of its factories shut and their activities moved to lower-cost locations abroad. The student team was charged with recommending deal terms to an independent investment committee whose members had deep experience in the impact investment field.

• Featured Case

For thirty-five years, Dollar Tree, a discount retail chain selling general merchandise, had held its fixed price point steady, pricing all of its household items, food, stationery, books, seasonal items, gifts, toys, and clothing that made up its diverse and ever-changing assortment at $1.00. While all other dollar store chains had raised prices over the years to keep up with inflation, Dollar Tree had never budged on its price. However, in late 2021, the company announced that Dollar Tree was “breaking the buck” and raising prices on all goods to $1.25. Would the demise of the $1.00 price point bring about the downfall of Dollar Tree or could the retail chain weather its price change without alienating its price sensitive shoppers through smart marketing, pricing, and branding strategies?

• Featured Case

The setting for this case is the Sian Flowers, a company headquartered in Kitengela, Kenya that exports roses to predominantly Europe. Because cut flowers have a limited shelf life and consumers want them to retain their appearance for as long as possible, Sian or its distributors used international air cargo to transport them to Amsterdam, where they were sold at auction or trucked to markets across Europe. The Covid-19 pandemic caused huge increases in the cost of shipping, so Sian launched experiments to ship roses by ocean using refrigerated containers. Chris Kulei, the Executive Director, was interested in not only the potential costs savings, but whether he could also market the reduced carbon footprint.

• HBS Working Paper

I investigate whether and how private equity fund managers (GPs) inflate their interim fund valuations (net asset values, or NAVs) during fundraising periods. Specifically, I study the extent to which the GPs inflate NAVs by managing valuation assumptions (e.g., valuation multiples), influencing the financial metrics (e.g., EBITDA and sales) reported by the private firms in their portfolios, or both. Using a sample of buyout funds and their portfolio firms in Europe, I find that funds managed by low reputation GPs show more dramatic forms of NAV inflation by managing upward not only valuation multiples but also portfolio firm earnings. The results are robust to a number of alternative explanations.

• Working Paper

Do information frictions limit the benefits of financial inclusion drives for the rural poor? We evaluate an experimental intervention among recently banked poor Indian women receiving government cash transfers via direct deposit. Treated women were provided automated voice calls confirming details of transactions posted to their accounts. The intervention increased women's knowledge of account balances and trust in their local banking agent. Indicative of improved consumption-smoothing by income-constrained women, administrative data show that treated women accessed government transfers faster when the service was active, with treatment effects dissipating after the notifications were discontinued.
