We estimate the impact of the Green Revolution in the developing world by exploiting exogenous heterogeneity in the timing and extent of the benefits derived from high-yielding crop varieties (HYVs). We find that HYVs increased yields by 44% between 1965 and 2010, with further gains coming through reallocation of inputs. Higher yields increased income and reduced population growth. A 10-year delay of the Green Revolution would in 2010 have cost 17% of GDP (gross domestic product) per capita and… 
Agriculture, Development and Sustainability in the Covid-19 Era
Domestic and international mobility restrictions helped to reduce the numbers of confirmed Covid-19 cases until the end of 2021. Indonesia entered 2022 with caution, however, as Omicron cases began
Economic Growth, Convergence and Agricultural Economics
After nearly two centuries of lagging behind the industrial countries, growth in many developing countries has surged since the early 1990s. This outperformance has major implications for almost all
Agricultural productivity and economic development: the contribution of clover to structural transformation in Denmark
This paper contributes to the debate on the impact of agricultural productivity on long run economic development. It presents evidence that widespread adoption of clover contributed to local economic
Climate Change, The Food Problem, and the Challenge of Adaptation through Sectoral Reallocation
This paper combines local temperature treatment effects with a quantitative macroeconomic model to assess the potential for global reallocation between agricultural and non-agricultural production to
Trade, Technology, and Agricultural Productivity
We examine the contribution of trade to the rise of modern agriculture, taking into account interactions between trade, input requirements, and technology adoption. We develop and estimate a new
Can Smallholder Extension Transform African Agriculture?
Agricultural productivity in Sub-Saharan Africa (SSA) lags far behind all other regions of the world. A long list of policy experiments has yielded more evidence on what fails than on what works. We
The Food Problem and the Aggregate Productivity Consequences of Climate Change
This paper integrates local temperature treatment effects and a quantitative macroeconomic model to evaluate the impact of climate change on sectoral reallocation and aggregate productivity. First, I
Structural Transformation of the Agricultural Sector in Low- and Middle-Income Economies
Movement of labor from agriculture to nonagriculture and the associated increase in farm size through structural transformation are at the core of economic development. We conduct a comprehensive
Commodity Booms and Structural Transformation: The Role of Input Use and Land Inequality
This paper studies the effects of an agricultural commodity price boom on structural transformation. I construct a shift-share measure of exposure to the commodity shock by combining climateand
Agricultural Development and Structural Change, Within and Across Countries∗
This study exploits rapid technological development during the Green Revolution (1960-1990) to estimate the causal effect of agricultural productivity growth on structural change both within and


Assessing the Impact of the Green Revolution, 1960 to 2000
Over the period 1960 to 2000, international agricultural research centers, in collaboration with national research programs, contributed to the development of “modern varieties” for many crops, which have contributed to large increases in crop production.

A detailed retrospective of the Green Revolution, its achievement and limits in terms of agricultural productivity improvement, and its broader impact at social, environmental, and economic levels is
The agricultural basis of comparative development
This article shows, in a two-sector Malthusian model of endogenous population growth, that output per capita, population density, and industrialization depend upon the labor intensity of agricultural
Agricultural Development and Structural Change, Within and Across Countries∗
This study exploits rapid technological development during the Green Revolution (1960-1990) to estimate the causal effect of agricultural productivity growth on structural change both within and
Agricultural Productivity Growth, Rural Economic Diversity, and Economic Reforms: India, 1970–2000*
A salient theme in D. Gale Johnson’s work is the importance of agricultural development for general prosperity and for economic diversification (e.g., Johnson 2000). Johnson has also noted that most
Agricultural Productivity and Structural Transformation. Evidence from Brazil
We study the effects of the adoption of new agricultural technologies on structural transformation. To guide empirical work, we present a simple model where the effect of agricultural productivity on
