Produkční funkce v makroekonomii
Koláčková, Adéla
Diploma thesis is concerned with production functions and their utilization in macroeconomics. Theoretical part describes and summaries general knowledge about production functions and their basics in macroeconomic theory. Produc-tions functions are described from the point of productivity measurement and estimation of potential product. In theoretical part, indicators of productivity and their alternatives are sum up. Practical part is based on estimation of Cobb-Douglas, CES and Sato produc-tion functions by least squares and non-linear least squares method. Results are compared and discussed with similar works in conclusion of thesis.

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%.

Different approaches to calculating TFP
Zeman, Jan ; Vltavská, Kristýna (advisor) ; Sixta, Jaroslav (referee)
The bachelor thesis deals with total factor productivity and ways of its calculation.The first goal is describing theoretically the principles of total factor productivity and what it reflects. Subsequently the work uses the data available to test the ways of calculation while considering the hours worked and number of employees as an input. The thesis then names the advantages and disadvantages of individual kinds of input and further shows the calculation of direct and indirect method, comparing and assessing the two methods at the end.

Estimate of Capital Services in the Czech Republic
Hudrlíková, Lenka ; Fischer, Jakub (advisor) ; Ondruš, Vítězslav (referee)
This diploma paper discusses the importance of implementation of capital into the system national accounts. The purpose of this work is an estimation of capital services for real data of the Czech Republic. Conducted its own calculation is first such comprehensive estimate of the capital services, which was made. The diploma paper is divided into three parts. In the first part there is a explaination of concept of capital services and the methods of estimation and possible ways of calculating the necessary data. In the second part there is already done my own calculations of estimate of capital services used the methodology recommended by the OECD, but subject to certain adjustments, which are better suited to national conditions. Due to the volume of data all the calculations are listed in the Annex. In the text work is illustrative example of one sector of economic activity and the economy as a whole. The last section deals with experimental estimates of impact of capital services on macroeconomic aggregates, particularly gross domestic product. Other possibilities obtained an estimate of capital services, it is possible to estimate multi-factor productivity. Capital services can be used to express the input of capital.

Dopad PZI na produktivitu -- Spillovers efekty v České republice
Lehmann, Richard ; Klosová, Anna (advisor) ; Castro, José Villaverde (referee)
This dissertation analyzes productivity changes connected with inflow of foreign direct investment. Specifically indirect effects of foreign direct investment (spillovers) on firms in the Czech Republic in period 2000 -- 2006 are analyzed. As a proxy for productivity spillovers is used total factor productivity, which is retrieved by implementing the Levinsohn -- Petrin technique, which control the simultaneity bias in the production function. Using firm-level data, obtained from Amadeus database, a significant spillovers effects of foreign direct investment on productivity were identified -- a stronger positive impact on upstream sector and weaker negative impact on downstream sector.
