Foot-and-mouth disease is one of the most contagious diseases of animal livestock. We used statistical tools to explore the dynamics of epidemics and to evaluate the consequences of virus reintroduction in France. We developed a stochastic farm-based model adapted to the French farm structure from previous modeling works following the 2001 epidemic in the United Kingdom. This model depends upon...

This paper presents a synthesis of the main theoretical and empirical contributions that analyse production choices of farm households living and operating in developing countries. The review is particularly concerned with recent micro-economic contributions that highlight the trade-off farm households typically face, between full-income risk and expected return, while making production decisio...

This paper reported on a decision support system (DSS) for strategic planning on pig farms. The DSS was based . on a stochastic simulation model of investment decisions (ISM). ISM described a farm with one loan and one building using 23 variables. The simulation model calculated the results of a strategic plan for an individual pig farm over a time horizon of a maximum of 20 years for a given s...

Josephson, Anna Leigh. M.S., Purdue University, December 2013. How Population Density Influences Agricultural Intensification and Productivity: Evidence from Ethiopia. Major Professors: Jacob Ricker-Gilbert, Raymond J.G.M. Florax. We use household-level panel data to estimate how population density impacts agricultural intensification and farm income in Ethiopia. We hypothesize that increases i...

The paper determined optimum farm plan for food security among smallholder farmers in Imo State, Nigeria. Data were collected with structured and validated questionnaire from 180 smallholder crops farmers in Imo State. Data were analyzed using descriptive statistics (mean, frequency distribution and percentages), budgetary analysis and linear programming model. Results show that the mean age of...

This paper shows that the asymmetric information present in the relationship between the government and agricultural producers has led to persistent problems in the application of land taxes (Imposto Territorial Rural – ITR) in Brazil. The main result is that, when the asymmetric information is taken into account, some use of output taxes in the optimal tax scheme may be more desirable than a p...
