## In authors' words

### Abstract

Purpose: This paper examines governance mechanisms in Moroccan listed family firms, emphasizing how anticipated regulatory changes interact with strong family entrenchment to affect real earnings management and financial performance. Design/methodology/approach: This study analyzes 42 family firms listed on the Casablanca Stock Exchange from 2016 to 2022. It uses a dynamic panel with the System GMM estimator to address endogeneity, unobserved heterogeneity and moderation. Findings: The results indicate that a governance hierarchy emphasizing cognitive diversity, particularly gender diversity, more effectively challenges family power than structural independence does. While board independence reflects symbolic compliance and is associated with negative performance effects, gender diversity serves as a governance barrier that disrupts family entrenchment and significantly reduces opportunistic real earnings management. Research limitations/implications: The study is constrained by limited data access given the relatively small number of listed firms in Morocco. Comparative studies across emerging markets could examine whether the governance hierarchy we identify also appears in other legal and cultural contexts. Practical implications: The findings indicate that gender diversity is a strategic advantage for long-term survival, rather than a regulatory burden. It helps safeguard the family legacy by preventing value-destroying earnings manipulation that family CEOs might engage in to maintain control. Originality/value: This paper develops and tests a governance hierarchy model, showing that governance mechanisms occupy distinct positions, and extending previous work on the configurational perspective of corporate governance.

### What they set out to do (purpose)

To examine how governance mechanisms in Moroccan listed family firms interact with family entrenchment to affect real earnings management and financial performance.

### Who or what was studied (sample)

42 family firms listed on the Casablanca Stock Exchange, observed from 2016 to 2022.

### How they did it (methods)

Dynamic panel analysis using the System GMM estimator to address endogeneity, unobserved heterogeneity, and moderation effects.

### What they found (results)

A governance hierarchy in which gender diversity, rather than board independence, more effectively curbed family entrenchment: board independence was associated with negative performance effects, while gender diversity significantly reduced opportunistic real earnings management.

## Commentary

### In short

The finding combines a systems (S) structure, in which governance mechanisms occupy distinct positions within a hierarchical governance system, with a relationships (R) structure, in which specific mechanisms are shown to relate differently to family power and firm performance.
