Important lessons for policy makers are provided here as contributors evaluate the effectiveness of domestic economic policies and the recommendations of international organizations such as the World Bank regarding the economic development of developing countries. Challenges posed by debt problems, corruption, population dynamics, poverty, and the absence of adequate human and physical capital are highlighted. Contributors cast doubts on the conclusions of the prevailing theories of economic development with patterns of economic change over the course of the 20th century. Their findings point out the issue of inadequate social capability as a critical factor in understanding the lack of economic development in many developing countries. They suggest that contemporary theorizing tends to pinpoint necessary but insufficient conditions for the successful implementation of development strategies in these countries.

Commodity markets are integral to the global economy. Understanding what drives developments of these markets is critical to the design of policy frameworks that facilitate the economic objectives of sustainable growth, inflation stability, poverty reduction, food security, and the mitigation of climate change. This study is the first comprehensive analysis examining market and policy developments for all commodity groups, including energy, metals, and agriculture, over the past century. It finds that, while the quantity of commodities consumed has risen enormously, driven by population and income growth, the relative importance of commodities has shifted over time, as technological innovation created new uses for some materials and facilitated substitution among commodities. The study also shows that commodity markets are heterogeneous in terms of their drivers, price behavior, and macroeconomic impact on emerging markets and developing economies, and that the relationship between economic growth and commodity demand varies widely across countries, depending on their stage of economic development. Policy frameworks that enable countercyclical macroeconomic responses have become increasingly common-and beneficial. Other policy tools have had mixed outcomes.
