Essays On Socioeconomic Shocks And Policies In Agriculture, Wilman Iglesias

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

The three chapters of this doctoral dissertation estimate the responses of agricultural productivity, production value of agriculture, and crop supply to some external shocks and policies. Using unique panel datasets for Colombia and the United States, this research provides new insights regarding the responsiveness of agriculture to some socioeconomic effects and related market policies. Chapter 1 studies the impact of armed conflicts in rural areas on legal agricultural productivity in Colombia by using a production function that includes violence shocks such as the forced intra-national displacement of the rural population from 1995 to 2017. Chapter 2 investigates the effect of …

The Impact Of The African Growth And Opportunity Act (Agoa): An Empirical Analysis Of Sub-Saharan African Agricultural Exports, Addisalem Zenebe

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

The African Growth and Opportunities Act (AGOA) which was signed into law in 2000 as part of U.S. trade legislation has the objectives of increasing trade and investment between the U.S. and eligible Sub-Saharan African (SSA) countries, by reducing or eliminating tariffs applied to African exports of different products. This Act represents a promising approach to economic growth and development in SSA through international trade.

This thesis examines the impact of AGOA on African agricultural exports. The study uses the gravity trade model framework and panel data depicting annual agricultural trade from 35 eligible SSA countries to the United States …

Net Energy Of Cellulosic Ethanol From Switchgrass, Marty R. Schmer, Kenneth P. Vogel, Robert B. Mitchell, Richard K. Perrin

Department of Agricultural Economics: Faculty Publications

Perennial herbaceous plants such as switchgrass (Panicum virgatum L.) are being evaluated as cellulosic bioenergy crops. Two major concerns have been the net energy efficiency and economic feasibility of switchgrass and similar crops. All previous energy analyses have been based on data from research plots (<5m²) and estimated inputs. We managed switchgrass as a biomass energy crop in field trials of 3–9 ha (1 ha=10,000m²) on marginal cropland on 10 farms across a wide precipitation and temperature gradient in the midcontinental U.S. to determine net energy and economic costs based on known farm inputs …
