Mathematical Models of Production
Hanzlíček, Tomáš ; Půža, Bedřich (referee) ; Mezník, Ivan (advisor)
The thesis deals with the mathematical modelling of economic processes, particulary production. Basic approach, models and methods of modelling concerning the mentioned area are described. Further, specific characterizations are investigated. Application of selected methods to typical examples is presented. In the final part models on concrete data are constructed.

The analysis of impacts of the foreign exchange intervention making by CNB on the company CGI
Macháček, Marek ; Rotschedl, Jiří (advisor) ; Čermáková, Klára (referee)
The aim of this thesis is to determine the impact of the foreign exchange intervention, which was conducted in November 2013, based on analysis of production and profit function. From the results of each analysis I can accept the hypothesis about the negative impact of the foreign exchange intervention on the company CGI. Analysis of the production function shows that if the firm is profit maximalist, it would have reduced number of employees by approximately by 30 % after the intervention. The negative impact of the intervention was also confirmed by the higher gain on the real profit function when there is changing the prices of inputs and outputs in terms of no intervention. In an analysis of a hypothetical profit function assuming a fixed variable, the hypothesis was not confirmed and contrary the higher company profit was reached after the intervention. The work also brings an interesting and valuable finding, how many employees should the company hire and what is the optimal size of the product to maximize its profit.

Productivity and its measuring aiming at individual size categories of companies.
ŘÍHA, Jaroslav
The main aim of this thesis was to assess the relation between productivity and size of company in selected sector of national economy construction industry. The sub-objectives were determined as follows: to gather theoretical information on the topic, to analyse the productivity according to the individual size categories of companies in the selected sector, to assess the relation between the size of company and the productivity and to ascertain the level of productivity in the Czech Republic in comparison with the selected sector.

Currency Shocks to Export Sales of Importers: A Heterogeneous Firms Model and Czech Micro Estimates
Tóth, Peter
To what extent can exporters cushion the impact of currency appreciation shocks by using imported intermediates? We apply a partial equilibrium model with heterogeneous firms. Producers can serve the domestic market, export final goods, or import inputs. In the model, an exogenous exchange rate shock simultaneously affects the variable costs and revenues associated with exports and imports. The impact of a hypothetical 1% appreciation of the domestic currency on sales is estimated using a panel of 7,356 Czech manufacturing firms observed from 2003 to 2006. We focus on the above period to exploit the rich within-firm variation in trade strategies. The variation is probably associated with the lifting of trade barriers due to Czech EU membership since 2004. For firms that both export and import, the model predicts a drop in total sales of 0.2%, a drop in export sales of 0.8%, and a rise in domestic sales of 0.2%.

Is labour homogenous on the food production line?
Šoman, Michal ; Lahvička, Jiří (advisor) ; Brožová, Dagmar (referee)
The thesis examines a homogeneity of labour on weekly data from 2009 tillfirst half of 2012 in an anonymous food company with high capital facilities which produce biscuit products. Model is estimated as a Cobb-Douglas production function where behaviour and experience of operators (age, sex, amount of trainings etc.) have an impact on an amount of product. The annual amount of product on the given production line is about 5,000 tons. The amount of output is significantly influenced by age and sex of operators who are working on given production line. If operators get older by one year (ceteris paribus), the amount of production will decrease by 0.4 % (in practice, it means by 19.95 tons per year). Another significant characteristic parameter which influences significantly product is sex of operators. If all men working on the given production line will be replaced by women, the amount of products will decrease by 6.7 % (in practice, it means by 333.75 tons per year). The experience of operators was measured by the number of completed trainings per one year. It was found that the increased amount of completed trainings have a significant impact on the amount of produced product. If operators attend additional training quarterly, the production on the given line will increase in better case by 0.4 % (in practice, it means by 18.01 tons per year). In this case additional trainings for operators have positive impact on company's revenue. Conclusion is that labour is not as homogenous as was expected in that type of company.

Cost analysis of the farm
PEJŘILOVÁ, Lenka
This thesis deals with problems of cost and profitability of farms producing the selected crop and livestock commodities. For the structure of the work is divided into 3 parts - theoretical part and practical part of the methodology. The theoretical part is devoted to the use of cost and production functions and the degree of cost-effectiveness. Complementing the analysis of systems of indicators, which is defined logarithmic metoda.V practical part of the theoretical findings are applied to a set of 76 farms, which are divided according to production areas in the period 2006 - 2010.

Estimate of potential output for economy of the Czech Republic: Production function approach
Šálek, Pavel ; Pánková, Václava (advisor) ; Školuda, Václav (referee)
The goal of this thesis is to estimate potential output of the economy of the Czech Republic from 1999 to 2011. In the first chapter I focus on description of the overall product of the economy, introduction and definition, mostly NAIRU approach, of the potential output and several approaches to estimate potential output. Production function is analysed in the following chapter from econometric as well as economic perspective. The most important properties of the production functions are also described in this chapter. In the end of the second chapter I deal with three most common types of production function. Estimated values of the variables in the production function including the value of the potential output of the Czech economy and relevant interpretations are presented in the last chapter of this thesis.
