The paper presents an analysis of the shadow prices of the greenhouse gas emissions in the Czech dairy production industry. There is employed the stochastic frontier multiple output distance function with two market outputs and one non-market (undesirable) output - greenhouse gas emissions - as a representation of a negative public good. The results show that shadow prices differ significantly between producers. Moreover, the price is not stable over time. Significant differences can be seen in shadow prices for the greenhouse gas emissions among the researched group of farmers with respect to the degree of intensification. Most noticeably, the higher...

The paper analyses the structure and level of international cooperation among African states in the area of agriculture and rural development. It focuses on the AU and its eight Regional Economic Communities. The international cooperation schemes between the World Bank, EU, FAO and African countries in agricultural policy are reviewed. The paper concludes that, despite numerous cross-border initiatives, governance of agricultural policies in the pan-African context remains fragmented. Policy-making and cooperation schemes need to be stepped up to address continent-wide challenges in the sector. There is an urgent need for the AU and the EU to intensify...

To order to raise chickens for meat, chicken farmers must select an appropriate breed and determine how many broilers to raise in each henhouse. This study proposes a mathematical programming model to develop a production planning and harvesting schedule for chicken farmers. The production planning comprises the number of batches of chickens to be raised in each henhouse, the number of chicks to be raised for each batch, what breed of chicken to raise, when to start raising and the duration of the raising period. The harvesting schedule focuses on when to harvest and how many broilers to harvest each time. Our aim was to develop proper production and...
Nonlinear Granger causality between grains and livestockOriginal Paper

Linear and nonlinear Granger causality between three grains: corn, soybean, wheat and two livestock commodities: live cattle and lean hogs, was verified. Weak evidence of linear causal relationships was found, supporting the results published in other studies. However, strong nonlinear causal relationships between grain and livestock returns were found, which had not yet been documented in the literature on this subject. The revealed relationships have different patterns and features, and in some cases, they arise from second moment dependencies, but nonlinearities of a different type were also found. Most of the discovered nonlinear relationships...
