Key Figures

Structural Transformation Paradigm era

Gary S. Becker[1] emerged as a prominent figure in development economics during the Structural Transformation Paradigm (1958-1979), with affiliations at Columbia University[3] and the University of Chicago[4]. Becker's[1] contributions centered on human capital as a driver of economic development, exemplified by his 1964 work Human Capital: A Theoretical and Empirical Analysis, with Special Reference to Education[7], which helped formalize the role of education in growth during this era. Albert O. Hirschman[2] shaped development thought through The Strategy of Economic Development[8], with positions at Harvard University[5] and Princeton University[6], connecting gradualist and strategic policy approaches to the era's concerns about sectoral change and international linkages. Hirschman[2]'s emphasis on policy-relevant reform and the interconnectedness of sectors and countries helped frame the Structural Transformation Paradigm's critique of one-size-fits-all growth models and contributed to the analysis of world-systems and dependency that characterized this era.

Policy and Institutional Turn era

Robert J. Barro [1], associated with Harvard University [3] and Yale University [4], emerged as a leading figure in the policy and institutional turn of 1980–2000. Barro [1]'s key contributions in this era include cross-country growth analysis and the governance-dynamics of democracy, evidenced by Economic Growth in a Cross Section of Countries [6] (1991) and Democracy and growth [7] (1996), which helped quantify how governance quality and political systems shape development. Paolo Mauro [2], associated with Harvard University [3] and Jerusalem University College [5], contributed to the era's focus on governance and corruption as development determinants. This is reflected in his 1995 paper Corruption and Growth [8], which quantified how corruption reduces growth and reshaped policy emphasis on governance.

Governance-Driven Open Growth era

Alain de Janvry [1], associated with the University of California, Berkeley [3] and Vanderbilt University [4], epitomizes governance-informed development scholarship in the 2001–2023 era. His key contribution, highlighted by the World development report, 2008: agriculture for development [5], is to frame how agriculture can drive growth and poverty reduction within governance and policy contexts, an idea central to governance-driven open growth. Élisabeth Sadoulet [2], also tied to the University of California, Berkeley [3] and Vanderbilt University [4], extends this governance-driven agenda through empirical and policy-relevant work in the era. Her contributions, echoing the same WDR 2008 paper, illustrate how governance quality, regulatory credibility, and institutional design condition productive diversification, informed by the World development report, 2008: agriculture for development [5].
