Landowners' Willingness To Supply Woody Biomass For Biofuel In West Alabama, Gilbert Adjoyi, Ellene Kebede

Professional Agricultural Workers Journal

Abstract

The Concern for national energy security, rural development, and climate change has created a wider attention for biofuels from woody biomass in recent times. For instance, West Alabama is an area of interest for stakeholders regarding the production of woody biomass. Therefore, the main objective of this study was to examine landowners’ willingness to supply woody biomass for biofuel in West Alabama. A mail survey of randomly selected landowners was conducted in eight selected counties. The results indicated that the average forestland owner is male, between ages of 40 and 57, with an average of 27 years of land …

Determinants Of Iowa Cropland Cash Rental Rates: Testing Ricardian Rent Theory, Xiaodong Du, David A. Hennessy, William M. Edwards

William Edwards

Based on the Ricardian rent theory, this study employs the variable profit function to analyze the determinants of Iowa cropland cash rental rates using county-level panel data from 1987 to 2005. Accounting for spatial and temporal autocorrelations, responses of local cash rental rates to changes in output prices and other exogenous variables are estimated. We find that Iowa cash rental rates are largely determined by output/input prices, soil quality, relative location, and other county-specific factors. Cash rents go up by $79 for a $1 increase in corn price in the short run. The marginal value of cropland quality, as represented …

The Impact Of An Eu-Us Transatlantic Trade And Investment Partnership Agreement On Biofuel And Feedstock Markets, John C. Beghin, Jean-Christophe Bureau, Alexandre Gohin

Department of Agricultural Economics: Faculty Publications

We assess the impact of a potential TTIP bilateral free trade agreement on the EU and US bio-economies (feedstock, biofuels, by-products, and related competing crops) and major trade partners in these markets. The analysis develops a multi-market model that incorporates bilateral trade flows (US to EU, EU to US, and similarly with third countries) and is calibrated to OECD-FAO baseline for 2013–2022 to account for recent policy decisions. The major policy reforms from a TTIP involve tariff and TRQ liberalization and their direct contractionary impact on US sugar supply, EU biofuel production, and indirect negative effect on US HFCS production. …

An Analysis Of Government Policy Impacts In The Ethanol And Sugar Markets, Hassan Marzoughi_Ardakani

LSU Doctoral Dissertations

ABSTRACT This study determines the impact of U.S. government policies on U.S. ethanol market and its consequences for the U.S. corn, sugar, and HFCS markets. Using corn as the primary input in ethanol and HFCS production in the United States, along with the substitutability between sugar and HFCS, has linked the U.S. ethanol market to the U.S. HFCS, sugar, and corn markets. To address the problem, two sets of data, quarterly and annual data, were collected and a simultaneous econometric model was constructed. Estimated results show that the “2007 Energy Independence and Security Act” will increase the domestic corn price …

Economic Analysis Of Cellulase Production Methods For Bio-Ethanol, Jun Zhuang, Mary A. Marchant, Sue E. Nokes, Herbert J. Strobel

Biosystems and Agricultural Engineering Faculty Publications

The cost of cellulase enzymes has limited the feasibility of producing ethanol from fibrous biomass. Traditional submerged fermentation (SmF) was compared to an alternative method of producing cellulase, solid state cultivation (SSC). Results from an economic analysis indicated that the unit costs for cellulase enzyme production were $15.67 (The prices are all 2004 prices in this article, except otherwise stated. We deflated newer prices to 2004 prices using a deflation factor 0.9 per year and inflated older prices to 2004 prices using an inflation factor 1.1.) per kilogram ($/kg) and $40.36/kg, for the SSC and SmF methods, respectively, while the …
