Model of Development of the Czech Agriculture
Gálová, Dagmar ; Zinecker, Marek (referee) ; Luňáček, Jiří (advisor)
The main goal this master thesis is the identification of key factors influencing the performance and production of Czech agriculture. The work contains into three parts. First part summarizes theoretically background concepts for construction models with looking historical contexts. The second part builds a data base for another work. The third part of the thesis is computational, formulates specific numerical models of possible answer. This part contains a discussion of the results and definitions of possible limits.

Essays on Model Uncertainty and Model Averaging
Skolkova, Alena ; Jurajda, Štěpán (advisor) ; Lafférs, Lukáš (referee) ; Mikusheva, Anna (referee)
In the first chapter of this dissertation I study the properties of a model averaging estimator with ridge regularization. I propose the ridge-regularized modifications of Mallows model averaging (Hansen, 2007, Econometrica}, 75) and heteroskedasticity-robust Mallows model averaging (Liu and Okui, 2013, The Econometrics Journal, 16) to leverage the capabilities of averaging and ridge regularization simultaneously. Via a simulation study, I examine the finite-sample improvements obtained by replacing least-squares with a ridge regression. Ridge-based model averaging is especially useful when one deals with sets of moderately to highly correlated predictors, because the underlying ridge regression accommodates correlated predictors without blowing up estimation variance. A two-model theoretical example shows that the relative reduction of mean squared error is increasing with the strength of the correlation. I also demonstrate the superiority of the ridge- regularized modifications via empirical examples focused on wages and economic growth. The second chapter focuses on the use of elastic-net regression for instrumental variable estimation. I investigate the relative performance of the lasso and elastic-net estimators for fitting the first-stage as part of IV estimation. Because elastic-net includes...

Rozdíly ve výši příjmů a starobních důchodů u mužů a žen v ČR
Slanařová, Barbora
This diploma thesis deals with differences in income and pension between men and women in the Czech Republic. The target was to evaluate time series and panel data of income and pension of both sexes and to evaluate the existence of differences by using econometrics methods. From the performed analysis was forecast the future development for next three years and then was created the marketing recommendation for retail store regarding the focus on consumers in the pension in the end.

Economic applications of geometric programming
Štěpánek, Ladislav ; Dupačová, Jitka (advisor) ; Zimmermann, Karel (referee)
Geometric programming is a special case of nonlinear programming, where objective function and constraints are shaped as posynomials. In this work we introduce geometric programming and solving methods. In~last chapter we will apply the geometric programming to Cobb-Douglas production function, create a model with random demand and possible extensions of this model. Powered by TCPDF (www.tcpdf.org)

Czech educational system in the international context
Kučera, Milan ; Cahlík, Tomáš (advisor) ; Břízová, Pavla (referee)
This bachelor thesis analyses the impact of chosen variables on results from PISA. The thesis describes the short existence of PISA, summarizes the results from PISA with aiming on aggregatable variables and also deals with critique of PISA. The thesis provides the insertion of the czech system of compulsory education in the international context of results and findings of PISA. Econometrics analysis based on panel data of 44 countries participating in PISA from years 2006, 2009 a 2012 were confirmed international autocorrelation in results of PISA, significantly positive impact of economic, social and cultural background and negative impact of the inequality in the distribution of wealth in society. For this purpose was used spatial autoregressive model using maximum likelihood estimation method. Powered by TCPDF (www.tcpdf.org)
