The study focuses on three important sectors - cereals, dairy and pork - and assesses the period after the accession of the Czech Republic to the EU (2004-2011). Firstly, the multiple output distance function models were estimated. Secondly, the TFP was calculated and decomposed into scale efficiency (SE), management component (MAN), technological change (TCH) and technical efficiency (TE). The results show that the TFP development was significantly determined by the TCH in each sector.

We estimated the exact level of threshold points of the imported wheat price that have different impacts on the Korean wheat flour price. Our empirical estimations proved the main hypothesis of this study, namely, that the impact of input price on output price is stronger at higher levels of the input price. In the sub-sample, which includes data from January 1993 to January 2008, the price transmission effect from the imported wheat to the domestic wheat flour in the Regime 3, in which wheat prices are the highest among our three regimes, is larger than that in the Regime 2. In the whole sample, which includes data from January 1993 to March 2014, the price transmission effect in the Regime 3 is larger than that in the Regime 2, and that of the Regime 2 is larger than that of the Regime 1.

In China, the matter of energy security may be immediately transmitted to the food security, imposing a pressure to China's macro-economy to a certain extent. This paper examines the long-run and short-run influence caused by the world crude oil prices and the RMB-dollar exchange rate on the five individual agricultural commodity prices (soybean, maize, wheat, colza oil, and japonica rice) in China. In this paper, the Granger causality approach is applied to test the long-run interrelationships with the weekly data from June 2002 to August 2013. In addition, the impulse-response analysis is utilized to study how the agricultural prices react to the sudden shocks in oil prices and exchange rate in the short term. The results reveal that the impulse response curves demonstrate that agricultural prices are not significantly affected by the abrupt changes in either oil prices or the exchange rate. Consistently, agricultural prices are neutral to the changes in oil prices in the long run while the exchange rate only Granger causes the prices of soybean. Ultimately, we present some sound reasons to explain the statistical results and propose some policy suggestions aimed at the China's food and energy security.

Complexity in economic theory is in general perceived from the perspective of external effects, while the problem may also have other connotations: as the so-called fallacy of composition, or the phenomenon of entropy. The problem of complexity indicates the need for further reflection on the holistic perception of economic processes. This is particularly evident in the case of agriculture, when the evaluation based mainly on microeconomic approach from the perspective of the effect/cost relationship loses sight of the environmental, social, and cultural context. Focus should also be put on the entropy approach, which takes into account the openness of socio-economic systems and the limitations of resources, including the environment. Both the operating practice of agriculture together with the institutional surrounding, and agricultural economics are more advanced in the area of solving the problems of complexity on the practical and theoretical grounds, but there are still many issues that require solutions, particularly quantification of externalities. The work is theoretical in nature and a heuristic approach was applied in the considerations.
