Three Perspectives On Innovation In European Agriculture: From Public Research To The Circular Economy, Michele Vollaro Jan 2020

Three Perspectives On Innovation In European Agriculture: From Public Research To The Circular Economy, Michele Vollaro

Theses and Dissertations--Agricultural Economics

The dissertation examines the idea that current and future challenges faced by the European agricultural sector call for a multidimensional approach combining the classical path of productivity growth with more stringent commitments to environmental protection, and more incisive mitigation and adaptation actions to mitigate climate change, all within a policy context of a transition toward the cyclical management of resources (inputs, outputs and wastes) inspired by the circular economy concept. The three essays of the dissertation aim to show: that agricultural productivity in Europe is supported by complementarities between public and private investments in agricultural research with remarkable results in …


Measuring Cocoa Agricultural Productivity: A Spatio-Temporal Econometric Approach, Yurlady Chaverra-Palacios May 2019

Measuring Cocoa Agricultural Productivity: A Spatio-Temporal Econometric Approach, Yurlady Chaverra-Palacios

Master's Theses

A significant increase of 50.5 percent in the national production of cocoa was registered between 2011 and 2015 in Colombia. Nevertheless, 5,890 tons were imported in 2015 to supply domestic demand. Unlike other crops, the production of cocoa has made a significant contribution to the income of approximately 38,000 families of which 90 percent are small farm-producers with very little capital. Facilitating credit for investment is one of the main strategies of the national government to increase cocoa productivity. Correspondingly, the impact of the credit for investment on the cocoa agricultural productivity and if those investments have a spillover effect …


Industrial Output Fluctuations In Developing Countries: General Equilibrium Consequences Of Agricultural Productivity Shocks, Iona Hyojung Lee Feb 2018

Industrial Output Fluctuations In Developing Countries: General Equilibrium Consequences Of Agricultural Productivity Shocks, Iona Hyojung Lee

Research Collection School Of Economics

This paper shows that a negative shock to agricultural productivity may increase food prices, and labor and capital can move away from manufacturing into agriculture to meet the subsistence requirement for food. This effect depends on income levels and openness to trade. Using annual manufacturing data and rainfall shocks as the instrument for crop yields (proxy for agricultural productivity), I find that an exogenous decline in yield decreases manufacturing output as well as employment and capital investment in manufacturing. Overall, crop yield variation can explain up to 44% of industrial output fluctuations in developing countries (rainfall shocks cause 31% of …


Financial Sector Development And Agricultural Productivity, John J. Onoja May 2017

Financial Sector Development And Agricultural Productivity, John J. Onoja

Master's Theses

Global concern is rising about the performance of the agricultural sector in view of its integral role in poverty alleviation, economic development and meeting an ever-increasing nutritional demand. At the epicenter of the concern is declining productivity due to poor financial inclusion of the sector leading to low investment and returns to agriculture. A cursory examination of the existing literature on the subject reveals quite varied dimensions to the analysis of agriculture productivity-financial development nexus. Focusing on the role of financial sector development as a catalyst to agricultural productivity, we employ panel data and advances fixed-effects econometrics approach to empirically …


Agricultural Productivity In The Greater Middle East, Zahra Tayebi May 2014

Agricultural Productivity In The Greater Middle East, Zahra Tayebi

Department of Agricultural Economics: Dissertations, Theses, and Student Research

The purpose of this research is to determine TFP growth in Iran, Pakistan, Afghanistan, Turkey and Syria considering weather as well as economic and social factors that might be affecting it. A translog production function was used to estimate TFP over the period 1980-2010. Precipitation, temperature, drought and irrigation were included in the analysis. The results show increasing agricultural productivity at the average rate of 2.66% during the period. Temperature and precipitation play a significant role in agricultural production and most frequent extreme drought episodes and irrigation affect, substantially, agricultural productivity growth in the region. The results highlight that respect …


Agricultural Productivity In Mercosur, Preeti Bharati Dec 2013

Agricultural Productivity In Mercosur, Preeti Bharati

Department of Agricultural Economics: Dissertations, Theses, and Student Research

This thesis applies econometric methods to investigate reported decline in productivity in the countries of Mercosur in Latin America. While non-parametric methods in general claimed thus, more recent studies using parametric approach exhibited mixed results. We show that the results are contingent to the estimation method employed, the dataset used and the degree of diversity in socio-political and economic environment prevailing in the countries analysed. Our results indicate that the region is experiencing 2.24% productivity growth dominated by technical growth (1.97%) and marred by low efficiency (0.24%), the latter being explained primarily by the quality of human capital in agriculture, …


Agricultural Productivity In Developing Countries, Lilyan E. Fulginiti, Richard K. Perrin May 2012

Agricultural Productivity In Developing Countries, Lilyan E. Fulginiti, Richard K. Perrin

Richard K Perrin

This paper examines changes in agricultural productivity in 18 developing countries over the period 1961-1985. We use a nonparametric, output-based Malmquist index and a parametric variable coeficients Cobb-Douglas production function to examine, whether our estimates confirm results from other studies that have indicated declining agricultural productivity in LDCs. The results confirm previous findings, indicating that at least half of these countries have experienced productivity declines in agriculture.


Institutions And Agricultural Productivity In Sub-Saharan Africa, Lilyan E. Fulginiti, Richard K. Perrin, Yu Bingxin May 2012

Institutions And Agricultural Productivity In Sub-Saharan Africa, Lilyan E. Fulginiti, Richard K. Perrin, Yu Bingxin

Richard K Perrin

Agricultural productivity in 41 Sub-Saharan Africa (SSA) countries from 1960 to 1999 is examined by estimating a semi-nonparametric Fourier production frontier. Over the four decades the estimated rate of productivity change was 0.83% per year, although the average rate from 1985-99 was a strong 1.90% per year. Former UK colonies exhibited significantly higher productivity gains than others, while Liberia and countries that had been colonies of Portugal or Belgium exhibited net reductions in productivity. We measure a significant reduction in productivity during political conflicts and wars, and a significant increase in productivity among those countries with higher levels of political …


Institutions And Agricultural Productivity In Mercosur, Preeti Bharati, Lilyan Fulginiti Oct 2007

Institutions And Agricultural Productivity In Mercosur, Preeti Bharati, Lilyan Fulginiti

Lilyan E. Fulginiti Publications

We revisit earlier estimates of agricultural productivity in original Mercosur member countries and later associates: Argentina, Brazil, Paraguay, Uruguay, Chile, Bolivia, Colombia, Ecuador, Peru and Venezuela, for 1972-2002. We estimate a translog frontier production function and revise our earlier estimates as well as those of others that indicated declining agricultural productivity. We find that the average rate for the region was a strong 2.25 percent. All the member countries experienced positive agricultural productivity growth for the sample period with Brazil being the fastest gainer. Institutions such as investments in public health and in public agricultural R&D, as well as an …

Green Revolutions And Miracle Economies: Agricultural Innovation, Trade And Growth, Brishti Guha Jun 2006

Green Revolutions And Miracle Economies: Agricultural Innovation, Trade And Growth, Brishti Guha

Research Collection School Of Economics

The purpose of this paper is to develop a simple model of an economy in which growth is driven by a combination of exogenous technical change in agriculture and a rising world demand for labor-intensive manufactured exports. We explore the relative roles of an exogenous agricultural productivity shock and rising export demand in a model with two traded industrial goods and a non-traded agricultural good, food. When the non-traded sector uses a specific factor, we show that technical change in agriculture may be the key to factor migration into industry, in particular driving intersectoral labor migration. A key assumption is …

We explore the relative roles of agricultural innovation and rising export demand in a model with two traded industrial goods and a non-traded agricultural good, food. When the non-traded sector uses a specific factor, we show that technical change in agriculture may be the key to sustained factor accumulation in industry, in particular driving intersectoral labor migration.
