A purposeful collection

Choose the decision
you need to improve.

Family-office research is complemented by relevant studies of family businesses, capital markets, property and financial decisions. Each article states the setting actually studied. An application to a family office is an editorial inference, not a claim that every original study sampled family offices.

Determining Drivers of Private Equity Return with Computational Approaches

Prosper Lamothe-Fernández; Eduardo García-Argüelles; Sergio Manuel Fernández-Miguélez; Omar Hassani-Zerrouk

Computational Economics · 2024-04-03

Helps family offices evaluate computational return models without confusing classification accuracy with investment performance.

An Accuracy Claim Is Not an Allocation Mandate: A Model-Risk Dossier for Private-Equity Forecasts

Computational models can help investigate private-equity return patterns, but classification performance is not an investment return. Drawing on Lamothe-Fernández and colleagues' analysis of 1,606 funds, this companion proposes a model-risk dossier for family offices evaluating forecasts, manager-selection tools, or AI-supported allocation research. It emphasizes target definitions, information timing, benchmark comparisons, distributional limits, and human approval.

Profitability of private equity: mean reversion and transitory shocks

Luis Alberiko Gil-Alana; Francisco Puertolas-Montanes

Journal of Economics and Finance · 2022-11-09

Separates historical return persistence from the cash availability and fund-specific evidence needed by long-horizon families.

Original practical companion

Patience Without Amnesia: A Shock-Persistence Review for Private-Equity Reporting

A smooth private-equity return series may contain economic persistence, valuation effects, or both. Gil-Alana and Puertolas-Montanes examine the statistical memory of regional pooled-IRR series. This companion proposes a family-office reporting process that separates model-based mean reversion from realizable liquidity, tests the age and basis of valuations, and links prolonged shocks to commitments and distributions.

Investing in Your Alumni: Endowments’ Investment Choices in Private Equity

Roland Füss; Stefan Morkoetter; Maria Oliveira

Journal of Financial Services Research · 2023-11-21

Provides an endowment-based lens for family offices distinguishing relationship-driven access from evidence of manager quality.

Original practical companion

Trusted Access, Independent Judgment: A Relationship-Disclosure Protocol for Family-Office Manager Selection

Relationships can open access to funds without proving their superiority. Füss, Morkoetter, and Oliveira examine alumni ties in university-endowment commitments to private equity and find that connected managers are more likely to receive commitments, without corresponding evidence of superior performance. This companion proposes a relationship-aware diligence process for family offices that preserves useful networks while making selection criteria, conflicts, and comparative evidence inspectable.

VC investors’ venture screening: the role of the decision maker’s education and experience

Alexandra Moritz; Walter Diegel; Joern Block; Christian Fisch

Journal of Business Economics · 2021-04-26

Informs a proposed calibration exercise for family-office committees while explicitly preserving the source population and stage limits.

Read research →Ask research agent

Original practical companion

The Committee Sees What It Knows: A Calibration Exercise for Venture Screening

Investment expertise can direct attention as well as improve it. Moritz and colleagues examine how education and experience relate to venture-screening preferences. This companion proposes a calibration exercise in which family-office reviewers independently assess comparable cases, explain disagreements, and examine missing evidence before turning screening preferences into investment judgments. It does not rank educational backgrounds or claim that any profile produces superior returns.

Navigating the Ambiguity of Impact Investing: How Impact Venture Capitalists Access New Markets, Founders, and Capital

Christian Garmann Johnsen; Johannes Lenhard

Journal of Business Ethics · 2025-06-28

Addresses how family-office LPs can allow evolving impact theses without losing accountability for claims and mandate changes.

Read research →Ask research agent

Original practical companion

Keep the Mission Flexible and the Claim Accountable: An Impact-Mandate Change Register

Ambiguity can enable innovation while making impact claims difficult to evaluate. Johnsen and Lenhard's ethnographic research examines how impact venture capitalists use flexible definitions to access markets, founders, and limited-partner capital. This companion proposes a change register that allows a family office to revise its impact thesis transparently while preserving beneficiary definitions, evidence requirements, decision rights, and the ability to challenge unsupported claims.

Ethical Sensemaking in Impact Investing: Reasons and Motives in the Chinese Renewable Energy Sector

Tongyu Meng; Jamie Newth; Christine Woods

Journal of Business Ethics · 2022-06-15

Provides a structured way for families to examine financial, personal, reputational and social motives in consequential energy investments.

Original practical companion

Why This Investment, and for Whom? A Three-Lens Deliberation for Renewable-Energy Capital

Impact-investment decisions combine financial evidence, personal commitments, reputational concerns, and aspirations for social benefit. Meng, Newth, and Woods examine these motives in the Chinese renewable-energy sector through ethical sensemaking. This companion proposes a structured family-office deliberation that asks what is feasible now, how earlier experience shapes judgment, and who may bear future consequences. It treats motives as matters for examination, not substitutes for diligence.

Green signals of new ventures: investigating the impact of environmental orientation on funding and the moderating role of lead venture capitalists

Verena Hossnofsky; Patrick-Peter Herold; Franziska Schlichte; Sebastian Junge

Small Business Economics · 2025-06-25

Helps family investors distinguish green fundraising signals and investor reputation from verified environmental outcomes.

Original practical companion

A Green Signal Is Not a Verified Outcome: A Diligence Bridge from Venture Narrative to Environmental Evidence

Environmental orientation can influence funding without establishing environmental performance. Hossnofsky and colleagues study green signals and lead-investor prominence in United States venture funding rounds. This companion proposes a diligence bridge for family offices: record the exact signal, distinguish intention from measured change, inspect the lead investor's contribution, and set proportionate evidence milestones before repeating impact claims.

Value, Values, and Valuation: The Marketization of Charitable Foundation Impact Investing

Supports family foundations in distinguishing capital purposes and making financial-social trade-offs explicit in transaction design.

Original practical companion

One Family, Several Capital Purposes: A Value-Integration Charter for Foundation Investments

A foundation can support social purpose while still allowing financial conventions to dominate investment decisions. Andersen and Tekula examine how charitable foundations and related organizations incorporate financial and social values. This companion proposes a charter that distinguishes capital purposes, defines permitted trade-offs, records how transaction design serves those purposes, and evaluates decisions against the objectives actually authorized.

From ambition to evidence: a practical tool for startup impact assessment

Guides proportionate impact-assessment pilots for family investors supporting early businesses with limited measurement capacity.

Original practical companion

Evidence a Startup Can Actually Produce: A Proportionate Impact-Assessment Pilot for Family Investors

Impact reporting can fail when investor expectations exceed a young company's capacity to measure. Eckerle and Terzidis develop design principles and a tool for startup impact assessment. This companion proposes a limited pilot that joins a theory of change, a small indicator set, explicit data-quality labels, and structured investor feedback. It treats the source's design-science contribution as a basis for testing rather than as proof that a scorecard improves impact or returns.

Drivers of Philanthropic Foundations in Emerging Markets: Family, Values and Spirituality

Family foundation values, cross-border partnership design and intergenerational stewardship. Directly studies business leaders and foundations, including family ties; family-office governance application is an editorial extension.

Original practical companion

A Values-to-Evidence Charter for Family Philanthropy Across Borders

Family philanthropy can preserve inherited values while remaining accountable to people who receive its support. Drawing on Giacomin and Jones’s historical study of philanthropic foundations in emerging markets, this companion proposes a charter that separates donors’ reasons for giving from evidence about what their giving accomplishes. It specifies how a family office can document traditions, negotiate local partnerships, share decision authority and revise funding when outcomes diverge from intentions. The charter is an untested editorial proposal, not a validated measure of philanthropic effectiveness.

How Billionaires Explain Their Philanthropy: A Mixed-Method Analysis of the Giving Pledge Letters

Hans Peter Schmitz; George E. Mitchell; Elena M. McCollim

Voluntas: International Journal of Voluntary and Nonprofit Organizations · 2021-03-12

Helps family offices distinguish public philanthropic pledges, reasons for giving, completed transfers and evidence of impact. Directly studies billionaire philanthropic discourse rather than family-office operations.

Read research →Ask research agent

Original practical companion

From Giving Pledge to Verifiable Commitment: A Family Office Accountability Ledger

Public statements about generosity communicate identity and purpose, but they do not by themselves establish that resources were transferred or that social outcomes improved. Building on Schmitz, Mitchell and McCollim’s analysis of 187 Giving Pledge letters, this companion proposes an accountability ledger connecting a family’s explanation for giving to authorization, funding, delivery and evidence. The process preserves the legitimacy of multiple motivations while preventing aspirational language from being presented as completed impact. It is an original editorial design for testing, not a finding about individual pledgers.
