Structuralist economics is an approach to economics that emphasizes the importance of taking into account structural features (typically) when undertaking economic analysis. The approach originated with the work of the Economic Commission for Latin America (ECLA or CEPAL) and is primarily associated with its director Raúl Prebisch and Brazilian economist Celso Furtado. Prebisch began with arguments that economic inequality and distorted development was an inherent structual feature of the global system exchange. As such, early structuralist models emphasised both internal and external disequilibria arising from the productive structure and its interactions with the dependent relationship developing countries had with the developed world. Prebisch himself helped provide the rationale for the idea of Import substitution industrialization, in the wake of the Great Depression and World War II. The alleged declining terms of trade of the developing countries, the Singer–Prebisch hypothesis, played a key role in this.
Dutt and Ros  argue that structuralist economists try to identify specific rigidities, lags as well as other characteristics of the structure of developing countries in order to assess the way economies adjust and their responsiveness to development policies. A normal assumption within this approach is that the price mechanism fails
- as an equilibrating mechanism,
- to deliver steady growth,
- to produce a "desired" income distribution.
- the importance of political and institutional factors in the analysis of economic problems.
- of the need to raise the level of domestic saving in order to raise the rate of investment given that external sources of finance are likely to be hard to come by
- inflation as a "social phenomenon" requiring for its elimination social, psychological and political-institutional changes, as well as orthodox monetary and fiscal policies.
- the false nature of dilemmas between for example ISI and EOI — planning and the market — agriculture and industry.
- the need to strengthen the productive and technological base.
- the importance of trying to improve the terms on which countries are integrated into the global economy and to improve international competitiveness.
- structural adjustment as only one component of structural change.
More recent contributions to structuralist economics have highlighted the importance of institutions and distribution across both productive sectors and social groups. These institutions and sectors may be incorporated macroeconomic or multisectoral models. At the macroeconomic level modern structuralists would trace the origins of their approach to Kalecki's Problems of Financing Economic Development in a Mixed Economy. FitzGerald’s version of this model of an industrializing economy has three commodity markets (food, manufactures and capital goods), foreign trade and income distribution which underpin the specification of a financial-sector with savings, investment, fiscal and monetary balances. For multisectoral models Social Accounting Matrices (SAMs) (an extension to input-output tables) are often used. Lance Taylor has provided both a technical introduction to a form of structuralist economics and critique of more mainstream approaches.
New structural economics
New structural economics is an economic development strategy developed by World Bank Chief Economist Justin Yifu Lin. The strategy combines ideas from both neoclassical economics and structural economics.
