Plain-language explanation.
Development Studies is an interdisciplinary field that examines why some countries are wealthy and others are poor, and what can be done about it. It draws on economics, sociology, political science, anthropology, and history to understand inequality, poverty, and the paths to human wellbeing.
Core concepts and standard treatment.
Core development studies covers theories of development: modernisation theory (Rostow's stages of economic growth — traditional society, preconditions, takeoff, drive to maturity, mass consumption; development as Westernisation; critique — ethnocentric, ignores structural constraints), dependency theory (Frank, Cardoso — underdevelopment is produced by the capitalist world system; core-periphery; unequal exchange — Emmanuel; import-substitution industrialisation — ISI — ECLA — Prebisch-Singer thesis), the Washington Consensus (Williamson — 10 reforms: fiscal discipline, trade liberalisation, privatisation, deregulation; implemented by IMF/World Bank structural adjustment programmes — SAPs; critique — one-size-fits-all), and human development (Sen — capability approach — Development as Freedom; Nussbaum — capabilities list; UNDP Human Development Index — HDI — life expectancy, education, GNI per capita).
Deeper theory, debates and edge cases.
Advanced development studies covers the political economy of development (Acemoglu and Robinson — 'Why Nations Fail' — inclusive vs extractive institutions; Rodrik — the 'trilemma' of globalisation; Piketty — inequality and capital — r > g; Easterly vs Sachs debate — 'The White Man's Burden' vs 'The End of Poverty' — big push vs incremental aid), randomised controlled trials in development (Banerjee and Duflo — J-PAL — Abdul Latif Jameel Poverty Action Lab; RCTs for development interventions — Progresa/Oportunidades, deworming controversy, unconditional cash transfers — GiveDirectly; critique of RCT-isation — Deaton, Cartwright), and global governance of development (SDGs — 17 goals, 169 targets — review via VNR; OECD DAC — official development assistance — ODA targets — 0.7% GNI; South-South cooperation; China's development finance — AIIB, BRI; decolonising development — BOND, Saferworld — shifting power in INGO sector).
How it is applied in practice.
At the development economist, INGO director, and multilateral policy adviser level, practitioners contribute to Journal of Development Economics and World Development; lead country-level development programmes (FCDO — bilateral aid; USAID; GIZ; UNDP — country programme documents); apply evaluation methods to development interventions (DCED — Donor Committee standard; theory of change — logframe vs adaptive management — PDIA — problem-driven iterative adaptation — Andrews, Pritchett, Woolcock; contribution analysis; realist evaluation); design microfinance and financial inclusion programmes (Grameen Bank model; BRAC — holistic graduation approach; mobile money — M-Pesa — Kenya; digital financial inclusion — G20 GPFI); and advise on humanitarian-development-peace nexus (OCHA — humanitarian coordination; cash and voucher assistance — UNHCR, WFP; durable solutions for displacement).
