Economics · Library

Economics is the academic discipline that studies the production, distribution, and consumption of goods and services and — at a broader theoretical level — the allocation of scarce resources under different institutional, behavioural, and policy frameworks. Modern economics has a more contested relationship with policy practice than most academic disciplines because the policy implications of any given research result are often direct and politically charged. The discipline divides into microeconomics (the study of individual agents — households, firms, markets), macroeconomics (the study of aggregate economy — inflation, unemployment, growth, monetary policy, fiscal policy), and a substantial set of applied-and-cross-cutting specialisations.\n\nThe global economics-PhD-program landscape is more concentrated than most disciplines. The "top-5" by Tilburg-rankings or RePEc rankings: MIT, Harvard, Stanford, Princeton, Chicago. The next tier: Yale, Berkeley, Columbia, Northwestern, Penn, NYU, Brown, UCLA. In Europe: LSE, Oxford, Cambridge, UCL, Bocconi, Toulouse School of Economics, Pompeu Fabra Barcelona, Bonn, ETH Zurich, the Stockholm School of Economics, the Paris School of Economics (PSE), the European University Institute Florence (the EUI). In Asia: NUS, HKU, Tsinghua, Peking. India's economics-research infrastructure runs through the Delhi School of Economics, Indira Gandhi Institute of Development Research (IGIDR Mumbai), the Centre for Development Economics (Delhi), Madras School of Economics, Indian Statistical Institute (ISI Calcutta and Delhi), JNU Centre for Economic Studies and Planning, the IIM economics groups, plus the substantial growth of private-university economics programs (Ashoka, Krea, Shiv Nadar, BITS Pilani Hyderabad).\n\nIndia's economics-academic-and-policy infrastructure has structural distinctness given the country's scale and the post-1991 reform trajectory. The Reserve Bank of India's Department of Economic and Policy Research; the Ministry of Finance's Chief Economic Adviser office; NITI Aayog's economic-policy think-tank function; the National Council of Applied Economic Research (NCAER); the Indian Council for Research on International Economic Relations (ICRIER); the Centre for Policy Research (CPR); the Observer Research Foundation (ORF); the Asian Development Research Institute (ADRI); the substantial post-2010 emergence of evidence-based-policy research through J-PAL South Asia and the IDinsight India teams. India's contribution to development economics globally — through Amartya Sen (Nobel 1998), Abhijit Banerjee (Nobel 2019, with Esther Duflo and Michael Kremer), Kaushik Basu, Raghuram Rajan, Arvind Subramanian — is disproportionate to the country's economics-PhD-volume.\n\nSubdisciplines and active research areas: microeconomic theory (game theory, mechanism design, contract theory); macroeconomics (monetary economics, fiscal policy, business cycles, growth theory); econometrics (the statistical-methodology subfield that has evolved through the 2008 Angrist-Pischke "credibility revolution" toward strong identification strategies); labour economics; public economics (taxation, public goods, welfare economics); industrial organisation (the analysis of firm-and-market behaviour); international trade (the discipline most directly relevant to AJG's core trade-intelligence vertical); international finance and macroeconomics; development economics (with the post-2010 RCT-evidence-based revolution); environmental and natural-resource economics (increasingly important given climate-policy questions); behavioural economics and experimental economics; financial economics (asset pricing, corporate finance, market microstructure); health economics; education economics; urban economics. The post-2018 emergence of "AI-and-the-economy" research and the rapidly-growing climate-economics field reflect how the discipline expands.\n\nFor a globally-mobile professional, the economics-PhD-pathway is the principal route into research-and-academic-faculty roles plus central-bank-and-multilateral-institution research positions (IMF, World Bank, OECD, BIS, regional development banks). The MA Economics is the principal master's-level credential. The applied tracks — MA Public Policy, MPP, MPA — sit at the policy-practice interface. Career destinations span academic faculty, central banks (the Federal Reserve System, Bank of England, ECB, RBI, BoJ, PBoC, Riksbank, and dozens of others have substantial PhD-economist staff), multilateral institutions, government economic-policy roles, financial-services research (sell-side strategy, buy-side macro research, hedge-fund macro analysis), management consulting (the economic-consulting firms — NERA, Charles River Associates, Compass Lexecon, Brattle Group, Frontier Economics, Cornerstone Research). AJG cross-links academy-economics to the journal-root-econ + paper-root-econ + the broader trade-intelligence vertical.
