In general, structuralist development economics “attempts to identify specific rigidities, lags, and other characteristics of the structure of developing economies that affect economic adjustments and the choice of development policy” (Meier 1984: 118). The main structuralist point was that neoclassical economics was not a universal science, that the price system varied in effectiveness over space, and that a new type of economics had to be developed for the Third World. In general, structuralist economics argued that developing countries had features that set them apart from the economies theorized by orthodox economics. These features included high levels of rural unemployment, low levels of industrialization, more obstacles to industrialization, and disadvantages in international trade. Structuralist economics in the 1950s and 1960s tried to remedy these problems by removing the obstacles to growth specific to poor countries.
