The relationships between national culture and organizational culture were analysed in 16 Argentinean companies. Sample was integrated by 429 employees (292 male, and 184 female), mean age 35 years old. Subjects completed, in their own work places, a socio-demographic questionnaire, a scale of national culture, and a scale of organizational practices. Results indicated that organizations adopt practices that, on average, reflect the cultural values of their country of origin. Multiple regression analysis showed that Argentinean national companies are characterized by practices closely associated with collectivism, high power distance, and high uncertainty avoidance. In contrast, Argentinean privatized companies adopted practices most linked to individualism, low power distance, low uncertainty avoidance, low paternalism, and low fatalism. The results are discussed in light of its strengths and weaknesses, and a new agenda for future research is suggested.
