Baldos, Uris Lantz Caldo. Ph.D. Purdue University, December 2014. Essays on Productivity Growth in Agriculture. Major Professor: Dr. Thomas W. Hertel This dissertation aims to explore the current trends in agricultural productivity and analyse its impact on the global farm and food system. Chapter 2 in this dissertation looks at the current trends in agricultural productivity in India – one most of the populous country in the world. In this chapter, productivity trends in Indian agriculture are examined by looking at changes in Total Factor Productivity – a measure which takes into account all farm outputs and inputs. Estimates in this chapter suggest that TFP growth for the 10-year period – between 1999-2000 and 2009-2010 – steadily grew at the national level. Looking at the 5-year estimates, TFP growth in the early 2000s was sluggish but this poor performance was offset by sharp growth in the late 2000s. Developments at the global scale ultimately affect world food production and prices. This dissertation develops a new framework for the analysis of productivity, prices, nutrition and land use in the context of a global economy. The Simplified International Model of agricultural Prices, Land use and the Environment (SIMPLE) forms the basis for Chapters 3 and 4. In Chapter 3, projections from the SIMPLE model are validated against actual changes in key agricultural variables during the historical period 1961-2006. Given observed growths in population, incomes and total factor productivity, SIMPLE can successfully replicate historical changes in global crop

An International Comparison of Productivity Change in Agriculture and the Economy as a Whole, Using Production-Frontier Approa

A common and longstanding assumption in the economic growth literature has been that total factor productivity growth is lower in the agriculture sector than in the rest of the economy.

This decomposition ...
