In this paper we discuss the state of corporate governance in five countries, Kuwait, Bahrain, the United Arab Emirates, Qatar and Oman, of the Arabian Gulf. The countries are similar in culture and part of a locality with characteristics which make it distinctive in terms of wealth, state of social, economic and political development and their economic dependence on hydrocarbon resources. We construct a measure of corporate governance using the OECD's 2005 survey data, which included these and many other countries in the sample. We anayze the resulting measures in the light of ongoing institutional developments in each country. Our findings are that Omasn appears as a clear leader followed by Kuwait and the United Arab Emirates, based on our corporate governance measurement scale. Bahrain and Qatar rank least highly. We discuss some of the underlying reasons for these results.
