Industry costs of equity: evidence from frontier markets

Frontier markets are considered a good destination for international diversification due to their low level of integration with global markets. However, a diversification strategy into frontier markets with respect to country factors does not optimally capture their full diversification potential. Enhancing this strategy by simultaneously incorporating industry factors improves the ability to diversify portfolio risk. We investigate the industry costs of equity in frontier markets using five asset pricing models, taking into account the differences in five regions of frontier markets, namely, Africa, Eastern Europe, the Middle East, Latin America and Caribbean, and Asia. Additionally, we examine how well the explanatory factors of developed and emerging markets can explain industry returns in frontier markets. Our results precisely identified two industries in Africa, and two industries in Eastern Europe that exhibit segmentation from developed markets, and two industries in Africa and one industry in Asia show segmentation from emerging markets. However, we document the limited temporal variation in four regions of frontier markets indicating more precise estimates than US, UK, and European ones. Unlike previous studies, our findings show that the time-varying slopes in frontier markets follow a random-walk process.
