The purpose of this paper is to examine the mediating role of job involvement as high-performance work system (HPWS) on the relationship between human resource (HR) practices and employee performance in multinational corporations (MNCs) in developing economies using Ghana as a case study.

Using questionnaires to collect data from 317 employees and ten MNCs in Ghana, structural equation modeling (SEM), multiple regression and bootstrapping analysis were used to analyze the data.

The results showed that an HPWS proxy as job involvement fully mediates the relationship between HR practices and employee performance. The findings also showed that training and development and compensation and reward have a significant and direct positive effect on employee performance.

This paper provides a practical guide to management and corporations on the significance of training and compensation on employee performance in MNCs. The study, therefore, recommends managers of firms and corporations to take a serious look at their HR practices and institute an HPWS, which can positively improve both corporate and employee performance.

This paper enhances our understanding of micro-level HPWS in the form of job involvement as a positive mediator between training and development and employee performance on the one hand, and between compensation and reward and employee performance on the other hand in work organizations in a less-studied context.

The purpose of this paper is to compare how the various sectors among the largest companies in Ghana have incorporated sustainability into their mission, vision and value statements.

The mission, vision and value statements of the 100 largest corporations in Ghana, known as Ghana Club 100 (GC100), were extracted from the firms’ official websites. These firms were grouped into nine sectors, and the sustainability components in the mission, vision and value statements were subjected to cross tabulation and thematic contents analysis to establish the sectoral variations.

In formulating their mission, vision and value statements, GC100 firms were more than six times likely to include economic sustainability themes than environmental sustainability themes. Even though three out of every five GC100 firms are financial institutions, the manufacturing and the extractive sectors and firms ranked 1st−20th are three times likely to incorporate all the sustainability dimensions (i.e. economic, social and environmental) into their mission, vision and value statements. Firms in the financial sector and those ranked 80th−100th were more likely not to publish either a mission, vision or value statements online.

This study reveals the magnitude of the strategic pronouncements such as mission, vision and value statements of large firms in emerging economies and how they are aligned with sustainability. This could serve as a basis for formulating guidelines to reinforce efforts that contribute to corporate sustainability.

Research on how large firms align sustainability into their mission, vision and value statements is not a new agenda, but fragmented in the context of the emerging economies. The novelty is that this study addresses this gap and contributes to this topic from a sectoral comparative perspective of largest organization in Ghana, an emerging economy.
