Does enterprise participation in global markets ensure sustainable income growth? Policies have often been designed in the belief that this is true, but competitiveness and participation in international markets may take very different forms, and developing countries do not always benefit. This book presents a series of rich and original field studies from Latin America, conducted by the authors with the same consistent methodological approach, and represents a theory-generating exercise within clusters and economic development literature. The main question addressed is how Latin American small and medium-sized enterprises (SMEs) may participate in global markets in ways that provide for sustainable income growth, the “high road” to competitiveness. In contrast, the “low road” is often typically followed by small firms from developing countries, which often compete by squeezing wages and revenues rather than by increasing productivity, salaries, and profits.
