Economic growth and agricultural land conversion under uncertain productivity improvements in agriculture

FOODSECURE Working papers from LEI Wageningen UR

Abstract: We study how uncertainty in the evolution of agricultural productivity interacts with economic and population growth, and the associated the demand for food. We use two-sector Schumpeterian model of growth, in which a manufacturing sector produces the traditional consumption good and an agricultural sector produces food to sustain contemporary population. Sectors differ in that agriculture also demands land as an input, itself treated as a scarce form of capital. In our model both population and sectoral technological progress are endogenously determined, and a number of key technological parameters of the model are structurally estimated using 1960-2010 data on world GDP, population, cropland and technological progress. Introducing random shocks to the evolution of total factor productivity in agriculture, we show that uncertainty optimally requires more land to be converted into agricultural use as a hedge against production shortages, and that it signficiantly affects both consumption and population trajectories.
