In the twentieth century, big business in Mexico invested much more in voluntary encompassing associations than business did elsewhere in Latin America. Multisectoral associations like the CCE, the CMNH, Coparmex, and COECE are rare in the other large countries of the region. Three primary factors gave Mexican business stronger incentives to invest in these associations. First, Mexican business was excluded from elections, PRI politics, and appointments to top government positions and therefore relied more on associations to channel business's organized participation in politics and policy making. Second, in some periods, government actions were threatening to business interests and prompted defensive organization. Third, in other periods of closer cooperation between business and government, government officials relied heavily on these associations to mediate relations with business, giving big business further incentives to invest in associations.
