The main contribution of Phylaktis and Xia (2006) is to find the reasons for the different behavior of emerging markets relative to developed markets by comparing the dynamics of emerging markets’ global, country and industry effects at the firm level. Compared to developed markets, emerging markets have higher country effects and lower global and industry effects, which explains why the global and industry effects surpass the country effects in developed markets whereas the country effects still dominate the global and industry effects in emerging markets when focusing on market level evidence. According to Phylaktis and Xia (2006), even though the dynamics of firms’ global, country and industry effects are different between emerging and developed markets, they are systematically linked to the firms’ foreign sale ratios and ADR listings. Nevertheless, the paper shows that the link between the firm’s factor effects and the TMT sectors is volatile and unstable over time.
By applying a factor model to a sample data of 1893 firms representing 37 countries within 24 industry categories from Jan 1990 to Dec 2002, the authors measure the global, country and industry effects in firm level returns. The starting point is the standard
