Price Volatility Modelling – Wheat: GARCH Model Application


This paper is focused on the modelling of volatility in the agricultural commodity market, specifically on wheat. The aim of this study is to develop an applicable and relevant model of conditional heteroscedasticity from the GARCH family for wheat futures prices. The GARCH (1,1) model has the ability to capture the main characteristics of the commodity market, specifically leptokurtic distribution and volatility clustering. The results show that the forecasted volatility of wheat has a tendency towards standard error reversion in the long-run and the position of price distribution is closed to the normal distribution. The wheat production can be hedged against the price variability with long-term contracts. The price of wheat was influenced during the years of 2005 to 2015 by different events, in particular; financial crisis, increasing grain demand and cross-sectional price variability. The results suggest that agricultural producers should focus on short-term structural events the wheat market, rather than long-term variability.

Economic Crisis And the Fragility of World Wine Export


The paper investigates the impacts of economic crisis on the duration of word wine exports for 40 leading wine exporter countries between 2000 and 2012. We analyze three attributes of wine exports embodied in exports relationships: the initial value of exports, the growth of exports within a spell, and the hazard of exports ceasing. Our results indicate that wine exports are rather short lived even for leading wine exporter countries. Our estimations imply that economic crisis has not significant impacts on initial value of wine export starting before crisis, whilst it has negative effects on spells beginning after crisis. However, economic crisis does not influence the export growth, and decrease the pr obability of failure of wine exports.

Exploitation of Agricultural Land in the Czech Republic and EU Countries


The primary objective of the paper is to assess the extent and exploitation of agricultural land in the CR and EU countries based on selected macro-socioeconomic indicators in order to determine the position of the CR and future desirable exploitation, protection and stabilisation of agricultural land in the CR. The following methods will be employed in order to meet the objective: (1) The Coefficient of Geographical Association (CGA) and my own modified coefficients of association reflecting the impact of exploitation of agricultural land on indicators of the country’s economic level. (2) Comparison (shrinkage of agricultural land, workforce in agriculture and market price of agricultural land in selected countries). (3) The Coefficient of Ecological Stability to assess the extent of stable and unstable areas in EU-27 countries. The following data are used for calculations: Eurostat (2009, 2015), World Bank and FAOSTAT (1993-2014). The extent of agricultural land in the CR (2014/1993) has been decreasing more slowly than in the detailed comparison countries (5 countries with the lowest CGA). The price of the agricultural land (2014) is lower than in France, Germany and Poland; nevertheless, the actual price rates are not as contrasting against these countries if purchase parity is considered. The Coefficient of Ecological Stability ranks the Czech Republic in the second half of the list of EU-27 countries (22nd place). While the ecological stability of land has decreased slightly in Germany and France (2009-2015), an improvement has occurred in the CR.

Current Trends in Training of Managers in the Field of Information And Communication Technologies And Identifying the Barriers to Education of Managers


Lately lifelong learning has become an integral part of the whole society. This is also the reason for the greatest development of new concepts serving just the implementation of lifelong learning policy. These changes in the process of continuous education are in practice much more than a comprehensive adaptation of the education system, which is why this trend is currently understood mainly in the developed countries of the world as a response to the changing labor market. Lifelong learning thus provides individuals with a better perspective and at the same time increases the chances of an organization in which they succeed and differentiate themselves on a global scale. That is why we can designate lifelong learning, learning and constant improving as an essential part of the development of managers. Education and training of human resources in organizations form a significant part of lifelong learning. Employee training focuses on shaping individuals, their skills and increasing their competitiveness on the global market. In today's turbulent and difficult-to-anticipate period, educational activities in management and training are important. This brings the ever-increasing demands for expanding, specialized and retraining education and thus the constant demand for new and more efficient forms of educatio n.

Agricultural Competitiveness of Vietnam by the RCA and the NRCA Indices, and Consistency of Competitiveness Indices


This study measures the static and dynamic agricultural competitiveness of Vietnam by the RCA and the NRCA. The dynamics of the trade competitiveness indicators are assessed in three ways: OLS regression, Markov matrices, and trend analysis. The paper, moreover, tests the consistency between the RCA, NRCA, and RTA indices. The results show that (i) Vietnam, generally, achieves strong competitiveness in crop and fishery sectors whilst it has weak competitiveness in livestock and processed food sectors; (ii) the country has the convergent pattern of agricultural competitiveness with the high stability of strong competitive and uncompetitive sectors; (iii) the country’s agricultural export strategy and competitiveness pattern are based on the natural-resource-intensive and traditional agricultural products with a slight improvement over time; and (iv) the RCA, NRCA, and RTA indices are strongly consistent in identifying the degrees of competitiveness and determining whether a country obtains competitiveness while they are weakly consistent in ranking competitiveness.

Selection of Communication Routes in Agriculture Equipment Company


Many publications describe problems in businesses and project management that are caused by communication. Team communication is a very complicated process full of soft aspects. One of basic problems represents a choice of an appropriate communication route kind useful for messages transmission between the team members as sources and recipients. It is a complex issue because of necessity to evaluate individual communication routes from many different perspectives. Therefore the suitable communication route of team members can be selected by a multicriterial mathematical model. Since communication can be understood as a distribution of messages, the appropriate model form can be based on the distribution model. The proposed model is derived from the three-dimensional transportation problem. The article discusses the possibility of this approach on the case study of communication modelling in the field of agriculture. Specifically, it is constructed and solved a model of communication problem for small team of agriculture equipment dealers.

The Use of Combined Models in the Construction of Foodstuffs Consumption Forecasting in the Czech Republic


Many authors all over the world attempt to perform time series analyses (at differing levels of expertise) in their published works. Knowledge of quantitative information is necessary for decision making in any domain. Therefore, it is more desirable to enter this field of problems and examine and develop everything that has been offered by these modern methodologies. In time series forecasting, the extrapolation methods are applied most frequently in practice. Currently, the combined models have been increasingly employed in experiments – these represent an aggregation of prognoses obtained from various separate models. The study presented is aimed at such new approaches, i.e. the construction of combined prediction models that are more realistic, more flexible and more concise in the time series modelling. This paper focuses on a subsequent assessment of combined prognoses constructed and a comparison of these with selected separate models having participated in the aggregate prognoses making. In order to obtain an efficient product, the Time Series Forecasting System (TSFS) component has been employed, being a component of the SAS programme system. For quality assessment of the models constructed, the assessment criteria selected in advance have been applied. The results of this empirical study have shown that in the domain of estimation of future foodstuffs consumption development, the techniques illustrated in this paper by examples of long-term time series from foodstuffs consumption area in the Czech Republic (CR), can be employed with success. This way represents a suitable supplement to complex econometric models.

Domestic and Foreign Origin Foodstuff Prices Comparison in Selected Retail Chains


The main objective is to verify whether it is possible to confirm differences in price policy not only in the division of chains according to the format of the shops but also in relation to Czech and foreign food and whether these findings can be clearly identified. The partial objective is to find the difference between Czech and foreign products in the context of chain approach according to other criteria such as price differences among products and among chains. There are eleven chains evaluated in the tables as well as 29 relevant food groups. The used underlying data is based on the data processed from the primary data obtained by the data collection in the retail chains. The average number of observations of one item, which is about 43 observations, of which 37 observations of Czech products and about 29 products with price. Only Lidl has a higher number of price observations from the total number of observations of foreign products. In the area of price policy evaluation (whether it is possible to confirm the differences not only in the division of the chains according to the format of the stores, but also in relation to Czech and foreign foods and identify clearly these findings), the difference is considered mainly according to the "low price“ of food and it can be said that there are noticeable differences among the chains, which also confirm different approach to Czech and foreign food and differences according to the format of chain stores. This paper originated in the context of the exploratory study „Prices of selected Czech and foreign food products in retail chains in November 2016“. The study was created for the needs of the Ministry of Agriculture of the Czech Republic.

Strategic Importance of the Quality of Information Technology for Improved Competitiveness of Agricultural Companies And Its Evaluation


The article discusses the issue of the use of information technology in the search for potential competitive advantages in agricultural companies. Information technology in agriculture should provide a clearly defined benefit for the management’s decision-making. If information technology is not being used to its full potential and if the results are interpreted incorrectly, the overall impact may be damaging to the position of companies in the competitive environment. Investment in information technology requires considerable sums that should return in the form of faster and better decision-making in which digitalized corporate processes play a complex role. Strategic decision-making concerning investments in information technology in various types of agricultural businesses varies depending on their size, focus, economic situation etc. In the context of the current state of agriculture in the Czech Republic and after a detailed analysis of available literature, the authors conclude that the issues of quality of information technology have not yet been systematically examined and resolved in Czech agricultural companies. For this reason, they consider it fruitful to focus their attention on this subject. The main objective of the paper is to develop and apply a methodological model for evaluating the quality of information technology in an agricultural business. In addition, we want to examine the broader impact of the criterion of IT quality from the perspective of its strategic importance for competitiveness and the extent to which it supports strategic management in practice.

Analytical System with Decision Tree for Economic Benefit


Data processing is an important aspect of business decision support systems (DSS). A good analytical system to process these data is essential to implement as a primary pillar for the development of complex expert systems. Businesses themselves are constantly confronted with deciding on investment opportunities to improve their performance. An important criterion for selecting investment is its profitability which cannot be easily determined when investing in analytical systems. Currently, there are two types of approaches to evaluating investments into information systems: normative and positive approaches. The simplest form of decisional analytical modeling is the decision tree (normative approach). The purpose of the article is to illustrate decision tree analysis as a component of an analytical system for evaluating two decision alternatives. The test case is demonstrated on an example of decision-making in agriculture.
