Bojovať alebo nebojovať proti internetovému pirátstvu: Je ACTA naozaj to čo potrebujeme?
Regináč, Jozef ; Singer, Miroslav (advisor) ; Potužák, Pavel (referee)
Internet piracy has recently been addressed by several policies introduced in US, such as SOPA and ACTA. These policies suggest the general opinion to be that piracy reduce profits. The focus of this thesis is therefore put on the introduction of theoretical concept capable of describing possible piracy impacts and then showing empirical observations to prove it. We developed our own modified time-dependent model of demand function with network effect, which suggests that piracy can have indeed different results on producers' profits depending on the conditions. Further, we showed on real data that the resulting piracy effect in film industry is indefinite and piracy in other industries results in various outcomes.

Analysis of the Price Convergence of CR towards EU
Havrlant, David ; Pánková, Václava (advisor) ; Mandel, Martin (referee) ; Singer, Miroslav (referee)
The price level convergence of the transition economies towards the reference economies is linked to the relative price of nontradables, which is explained by the total factor productivity differentials in tradable and nontradable sector. Basic concept is offered by the Balassa Samuelson model and its modifications. Testable equations are derived from these models, and the panel data approach is applied for their estimation. The results indicate faster growth of the relative price of nontradables in transition economies as succession of higher growth rate of the total factor productivity in tradable sector. Hence estimated models confirm the price level convergence of transition economies towards the reference economies. The analyses of price dynamics of the complementary field, i. e. of the tradables, follows, and the basic concept is represented by the rational bubble hypothesis. The stress is putted on the impact of the word prices on the price levels of the Czech Republic. After a cointegration analysis of the time series is carried out, the influence of the word prices of tradable commodities is estimated within a vector error correction model and regression analysis. This cost factors analysis is afterwards related to the export dynamics of the Czech Republic, and models suitable for quantitative analysis of export dynamics as well as its prediction based on vector error correction model and regression analysis are evaluated. Their forecasting ability is assessed within a simulation of ex-post forecasts and a root mean squared error. The aim is to consider the relationship between the price levels and the export dynamics, for the relation of both variables evaluated within the Granger causality seems to be less straightforward then the standard export equations suggest, and the estimated equations confirm significant influence of the export dynamics on the price level.
