  ABSTRACT: This paper utilizes the new non-parametric variance ratio tests based on signs and ranks to examine the random walk hypothesis of Euro exchange rates for 10 Middle Eastern and North African (MENA) currencies. The results of the new-variance ratio tests reject the random walk hypothesis for all currencies except the Kuwaiti and the Emirate currencies. Given the improved size and power properties of Wright's (2000) ranks and signs tests, the results of the new variance ratio tests are robust to the results of the traditional LOMAC variance ratio tests.

  Article: Empirical testing of different alternative proxy measures for firm size

  ABSTRACT: This paper examines the relationship among total sales revenue, total assets, book value of equity, and market value of equity for different economic sectors and time periods. Five statistical tools are used to examine the relationship among the different proxies of size of the firm for the period 1999-2002. Our study shows that the relationships among the four measures of the size of the firm are not the same for the different economic sectors and are not stable over time for each economic sector. Our results suggest that the use of the four measures interchangeably as a proxy for the firm size may not be appropriate.
