IMPACT OF PRODUCTIVITY GROWTH IN CROPS AND LIVESTOCK ON WORLD FOOD TRADE PATTERNS AgEcon
Ludena, Carlos E..
World food trade patterns have changed in the last 40 years with the share of world trade comprised of bulk commodities falling, and the share of world food trade comprised of processed commodities rising. These changes have been driven by a combination of supply and demand forces. On the demand side, world demand for livestock products and more highly processed food products has been rising more rapidly than that for bulk products. This increasing demand can either be met from domestic production or from foreign production – in the latter case resulting in increased international trade. The extent to which the increased demand can be met from domestic production depends importantly on the rate of productivity growth in the various components of the farm...

Productivity Growth and Convergence in Crop, Ruminant and Non-Ruminant Production: Measurement and Forecasts AgEcon
Ludena, Carlos E.; Hertel, Thomas W.; Preckel, Paul V.; Foster, Kenneth A.; Nin Pratt, Alejandro.
There is considerable interest in projections of future productivity growth in agriculture. Whether one is interested in the outlook for global commodity markets, future patterns of international trade, or the interactions between land use, deforestation and ecological diversity, the rate of productivity growth in agriculture is an essential input. Yet solid projections for this variable have proven elusive – particularly on a global basis. This is due, in no small part, to the difficulty in measuring historical productivity growth. The purpose of this paper is to report the latest time series evidence on total factor productivity growth for crops, ruminants and non-ruminant livestock, on a global basis. We then follow with tests for convergence amongst...

Domestic Support Policies for Agriculture in Ecuador and the U.S.-Andean Countries Free Trade Agreement: An Applied General Equilibrium Assessment AgEcon
Ludena, Carlos E.; Wong, Sara.
For the past two years the United States and Colombia, Peru and Ecuador have being negotiating a Free Trade Agreement (FTA). One of the main concerns of Ecuador's farmers is the asymmetry that exists between U.S. and Ecuador agricultural sectors. U.S. agriculture is highly subsidized in products such as rice, corn, and soybeans, products that represent an important export and subsistence products for Ecuadorian farmers. To reduce any negative effect that the FTA may have, Ecuador's government is studying land-based payments for rice, corn, soybeans and livestock producers. This program would offer direct initial support to farmers' income after the FTA enters in full effect. The objectives of this paper were twofold. First, estimate the effects on the...

DEVELOPMENT OF A STOCHASTIC MODEL TO EVALUATE PLANT GROWERS' ENTERPRISE BUDGETS AgEcon
Ludena, Carlos E.; McNamara, Kevin T.; Hammer, P. Allen; Foster, Kenneth A..
Increased domestic concentration and international competition in the floricultural industry are forcing growers to improve resource management efficiency. Cost management and cost accounting methods are becoming key tools as growers attempt to reduce costs. These tools allow growers to allocate costs for each crop, increasing their greenhouse planning abilities. Growers have a relative high degree of risk due to potential crop and market failure. Individual growers have different tolerance for risk and risk bearing capacity. Growers need a cost accounting system that incorporates production and market risk, a system that allows them to make informed business decisions. The research reported in this paper developed a greenhouse budgeting model that...

Georeferenced Assessment of Trade Liberalization Effects on Agriculture in Ecuador AgEcon
Ludena, Carlos E.; Schuschny, Andres; de Miguel, Carlos; Duran Lima, Jose E..
As the use of global and national computable general equilibrium (CGE) models has become more widespread, most policies still remain at the regional or sub-national level. This level of disparity requires an approach that bridges the gap between national results and sub-national policies. This study provides a methodology that combines micro-level information and the results of a CGE model with geographical information to spatially map the effects of trade liberalization on the agricultural sector. This methodology enables to distribute changes in value of production for each production unit according to the importance of a specific crop in the political administrative unit. These results show the geographic effects of the FTA on Ecuador's agriculture, and...

Biofuels Potential in Latin America and the Caribbean: Quantitative Considerations and Policy Implications for the Agricultural Sector AgEcon
Ludena, Carlos E.; Razo, Carlos; Saucedo, Alberto.
Rising oil prices has led to increased interest to replace domestic demand for liquid fuels for transport (petrol and diesel) with biofuel production (ethanol and biodiesel). One of the pioneers in biofuel production is Brazil, which since the 1970s has established a government program that promotes the production and consumption of ethanol. Currently, Brazil is the leading producer of ethanol in the world and has started also programs for biodiesel production based on soybeans, oil palm and other crops. Other countries in Latin America and the Caribbean have also expressed interest in biofuel production, and have started programs, and in some cases the legislation that promotes biofuel production. However, most of the analysis of biofuel crops has been...

Agriculture Productivity Growth: Is the Current Trend on the Track to Poverty Reduction? AgEcon
Valenzuela, Ernesto; Ivanic, Maros; Ludena, Carlos E.; Hertel, Thomas W..
In this study we evaluate the effect of annual productivity growth in agriculture over the 1991-2001 period on poverty in eleven developing countries. We compare this with the optimal pattern of productivity growth of comparable cost with the sole goal of maximizing poverty reduction. This comparison reveals that regional agricultural development is a viable option in the fight for poverty reduction.

Disaggregate Productivity Growth in Livestock Production: A Directional Malmquist Index Approach AgEcon
Ludena, Carlos E.; Hertel, Thomas W.; Preckel, Paul V.; Foster, Kenneth A.; Nin Pratt, Alejandro.
Limited data on the allocation of inputs to different activities has limited agricultural economists' attempts to measure sub-sector productivity growth in agriculture. However, recent developments have enabled us to estimate total factor productivity (TFP) growth for crops and livestock accounting for input-output allocation. This paper extends previous work on TFP measurement for livestock into ruminants and non-ruminant productivity measurement, given the differences in productivity growth rates among these species. The results show that the non-ruminant sector is more dynamic than the ruminant sector, driving most of the productivity growth within the livestock sector. Given the rapid rates of productivity growth observed recently, non-ruminant...
