Problem: What are the four dimensions of culture studied by Geert Hofstede? Identify and describe each. Choose one of the dimensions and explain how it is concretely exemplified in the global workforce. For example, a higher score for power distance in Spain accounts for that nation's greater degrees of hierarchy and of class stratification. Therefore, it is necessary for U.S. firms to be more formal and more respectful of titles when operating in Spain. In similar fashion, give concrete examples for the four dimensions of culture studied by Hofstede.
