Design and manufacture of an engraving LED laser
Adam, Tomáš ; Slaný, Martin (referee) ; Dvořák, Jaromír (advisor)
The thesis deals with the evaluation of achieved parameters of unconventional machining methods and their current use in practice. In addition, the design and construction of the prototype of the laser engraving device is carried out. Several tests are performed on the device and are compared with similar devices after evaluation. The entire construction is designed so that no special equipment is needed and the construction could be done in each workshop.
Generalized Nash Equilibrium Problems in Economics
Kratochvíl, Maxim ; Červinka, Michal (advisor) ; Adam, Tomáš (referee)
The aim of the thesis is to provide basic overview of term called Gener- alized Nash Equilibrium Problem (GNEP), mainly to the audience with economic education. Given term is the generalization of famous concept coming from Game theory called Nash Equilibrium Problem (NEP). Thesis describes basic properties of GNEP, illuminates main differences between NEP and GNEP and provides examples of both models. Thesis discuss hy- pothesis that there might exist economic models that could be advanced or solved by GNEP. One example of such economic model is presented to support given hypothesis. Keywords Generalized Nash Equilibrium Problems, abstract economy, social equilib- rium problem, pseudo-game, application.
Helicopter Drop of Money - Is It Feasible in Practice?
Gábrišová, Nela ; Holub, Tomáš (advisor) ; Adam, Tomáš (referee)
The main goal of this thesis is to discuss the famous Milton Friedman's concept of Helicopter Drop of Money in context of its applicability in the real world as a possible solution to liquidity trap. For better understanding, the thesis briefly de- scribes conduct of traditional and unconventional monetary policies. Key focus is put on describing assumptions necessary for the concept to yield desirable economic outcomes, and on detailed analysis of periods when zero lower bound on nominal interest rates is binding. Furthermore, roles of agents involved in execution of the concept, and important channels of transmission process are discussed from idealised theoretical view to real world possibilities of feasible execution. Additionally, prac- tical experience with direct cash distribution in Australia, and with quantitative easing programmes in Japan and the USA are explained. The last part analyses effects of increased monetary base on CPI inflation, money multiplier M2, and GDP in Japan and the USA using vector autoregression.

Modelling and comperative analysis of volatility spillover between US, Czech Republic and Serbian stock markets
Marković, Jelena ; Pečená, Magda (advisor) ; Adam, Tomáš (referee)
MASTER THESIS MODELLING AND COMPARATIVE ANALYZES OF VOLATILITY SPILLOVER BETWEEN US, CZECH REPUBLIC AND SERBIAN STOCK MARKETS Abstract This paper estimates Serbian, Czech and US stock markets volatility. Few studies analyzed stock market linkages for these three markets. The mean equation is estimated using the vector auto- regression model. The second moments is further estimated using different multivariate GARCH models. We find that current conditional volatilities for each stock is highly affected by the past innovations. Cross-market correlations are significant as well. However, there is a higher conditional correlation between Czech and US stock market indices compared to the conditional correlation between Serbian and US stock indices.
Understanding Information Asymmetries through Mechanism Design
Albert, Branislav ; Červinka, Michal (advisor) ; Adam, Tomáš (referee)
This thesis serves as an introduction and overview of the broad and closely related fields of mechanism design, contract theory, and information economics. Each chapter is intended to provide a self-contained guide to the particular area of application -- examples include adverse selection, moral hazard, and auctions. The reader should benefit from the thesis in two ways: by understanding the general notions of the revelation principle, incentive compatibility, and individual rationality from the mechanism design theory as well as by examining the particular information asymmetry models in the individual areas.

Arrow-Debreu Model of General Equilibrium
Juřena, Filip ; Červinka, Michal (advisor) ; Adam, Tomáš (referee)
Arrow-Debreu Model of General Equilibrium Filip Juřena Abstract In this thesis, we deal with the Arrow-Debreu model of general equilibrium, which is an integrated model of production, exchange and consumption. At the beginning, we present and discuss the original assumptions of the Arrow-Debreu model, i.e. the assumptions introduced by Kenneth J. Arrow and Gerard Debreu in 1954. Under these assumptions, Arrow and Debreu proved the existence of a general equilibrium. As a part of the proof, Arrow and Debreu showed that the equilibria of their model are the same as the equilibria of an abstract economy, or a generalized Nash equilibrium problem (GNEP). We describe the GNEP and look at whether there is a connection which allows to apply results developed by researchers from other disciplines to the Arrow-Debreu model. A part of the thesis is dedicated to a two-factor, two-commodity, two-consumer model, which is based on the original assumptions of Arrow and Debreu. In order to find the solution, we use a method called applied general equilibrium modelling and a software called GAMS. We examine the impact of better technology and taxes on consumers and producers. We have brief remarks on applications of the model at the end.
Differential equations and stability of competitive economy
Šabata, Marek ; Bárta, Tomáš (advisor) ; Adam, Tomáš (referee)
In the thesis, the author will analyse the theory of differential equations and its applications in economic model of price adjustment processes in competitive markets. First of all, the economic model sufficient to study stability of the market is introduced. Next microeconomic theory of competitive markets is presented and theory of differential equations is laid out, including the stability theory. Differences between the general model and the pure exchange model are discussed. Under certain microeconomic assumptions such as weak axiom of revealed preferences, gross substitutability, Walras's law and other properties of competitive markets, local and global stability of the market is proved.

Forecasting in futures markets: Front, back and rolling contracts
Badáňová, Martina ; Krištoufek, Ladislav (advisor) ; Adam, Tomáš (referee)
In the thesis we analyze sixteen commodity futures markets belonging to four families (energy type, grains, metals and other agricultural commodities) utilizing futures prices of front, back and roll futures contracts. As the tests for cointegration between front and back futures prices give us contradictory results we concentrate on roll contracts defined as the difference between front and back commodity futures contracts. We found that all commodity roll futures except natural gas and wheat futures exhibit long memory, which is usually connected with the fractal market hypothesis. Further, we employ specific ARMA and ARFIMA models and rolling window one-day-ahead technique to predict roll futures contract prices. Based on analysis of relation between resulting predictability and liquidity of roll futures contracts we concluded that lowest predictability is linked with the lowest liquidity among all commodities except metals and found evidence that predictability is positively dependent on liquidity among all commodities except metals, lumber, soybean oil and soybeans. The revealed dependence is strongest for energy type commodities. The relations and dependencies on the commodity futures markets are of high importance for all market participants such as hedge managers, investors, speculators and also for...
