Households' adoption of energy-efficient technologies in Greece: Independently or Jointly?
Spyropoulou, Dimitra ; Ščasný, Milan (advisor) ; Opatrný, Matěj (referee)
Hlavním cílem práce je analyzovat individuální preference řeckých spotřebitelů voblasti technologií osobních vozidel s alternativní palivem, včetně bateriových elektrických a plug-in hybridních elektrických vozidel. Vzhledem k nízkému rozšíření elektrických vozidel a velkému potenciálu solární energie v Řecku zkoumám dopad veřejné podpory kombinace fotovoltaiky a bateriových elektrických vozidel, pokud jsou tyto dvě technologie podporovány společně, na rozhodování spotřebitelů. K odhadu preferencí a ochoty platit reprezentativního vzorku potenciálních kupců automobilů v Řecku za peněžní, technické a politické atributy vozidel používám experimenty diskrétní volby. Shledávám, že spotřebitelé mají pozitivní vztah k bateriovým elektrickým a plug-in hybridním elektrickým vozidlům a že instalace fotovoltaiky je nástrojem pro plné využití výhod elektrických vozidel. Výsledky ukazují, že cena vozidla, provozní náklady, běžná doba nabíjení a dotace na instalaci wallboxů jsou klíčovými faktory ovlivňujícími přijetí elektrických vozidel. Zkoumám také nepozorovanou i pozorovanou heterogenitu spotřebitelských preferencí. Politická doporučení zahrnují společnou podporu přijetí elektrických vozidel s instalací fotovoltaiky a wallboxů, pokud je to možné, snížení počáteční ceny a zvýšení znalostí spotřebitelů o...
Demand for gas: Evidence from the 2022 energy crisis
Stuchlík, Jan ; Pertold-Gebicka, Barbara (advisor) ; Opatrný, Matěj (referee)
This thesis analyzes the effects of the 2022 energy crisis on changes in consump- tion patterns among Czech households, with the main focus on natural gas and other energy sources. We captured the effects using income and cross-price elas- ticity of expenditure shares of various goods. We calculated these elasticities from estimated parameters of a quadratic almost ideal demand system. The system parameters were estimated using the iterated feasible generalized non- linear least squares method on household-level data collected by PAQ Research. Demand for gas is income-elastic during the energy crisis, contrasting with other energy sources. Households made significant adjustments to their consumption of luxury goods and necessities in response to the high energy prices. The cross- price elasticity estimates show a decrease in expenditure shares of luxury goods and distant heat in relation to higher gas prices. Reduced healthcare and trans- port expenditure shares and increased solid fuels expenditure shares are related to higher electricity prices. In response to rising prices of necessities, households generally decrease expenditure shares of luxury goods. Households' reactions to the energy crisis are heterogeneous among socio-economic groups.
Green purchasing: Case of Bottled Water Consumption in the Czech Republic
Hanusová, Klára ; Ščasný, Milan (advisor) ; Opatrný, Matěj (referee)
To tackle various environmental issues, many of which stem from unsustainable consumer behavior, policymakers make an effort to transition toward a circular economy. One of the initiatives in the Czech Republic includes a reduction in single-use plastic waste. An example of this waste category are plastic bottles used for beverage packaging. Consequently, this thesis aims to uncover the determinants of bottled water consumption in the Czech Republic, as a similar study does not appear to exist in this context. Data (n=3 411) used for the analysis are obtained from a survey "TAČR Kohoutková". Methods used include estimation by Generalized Ordered Logit and Multinomial Logit. Results uncover socio-demographic characteristics, taste, health reasons, constructs from the Theory of Planned Behavior, and habits as predictors of bottled water consumption. It was found that highly educated people and those with a strong habit of drinking tap water are less likely to consume bottled water. The main consumers of this product appear to be those who negatively perceive tap water taste and healthiness, or positively perceive such characteristics of bottled water. On contrary, there is not enough evidence for identifying a relationship between environmental values and bottled water intake.
Evaluating Economic Policy Using the Synthetic Control Method
Opatrný, Matěj ; Havránek, Tomáš (advisor) ; Ščasný, Milan (referee) ; Tremewan, James (referee) ; Caselli, Francesca G. (referee)
The doctoral thesis consists of three essays that address the application of synthetic control method to various economic policy intervention. In the first essay I evaluate the quantitative effects of the Czech National Bank's commitment to keep the Koruna from appreciating that were put in place in 2013. I find that the commitment helped decrease unemployment substantially. The effect on overall output is also strongly positive, almost 2 percentage points for growth in 2015. The effect of the commitment on inflation is positive but not statistically significant at standard levels. In the second essay I focus on the impact of joining the EU on the Czech agriculture. The results show that the Czech Republic would have had a higher food index if it had not entered the CAM and CAP. Moreover, I show that the CAP and CAM had different impacts on farms in the Czech Republic and Bulgaria, which have the most comparable agriculture according to the results of the synthetic control method. In the final essay I estimate how the UK financial markets would have evolved if the Remain camp had won the referendum. The results suggest that there would not have been any significant change in the development of the FTSE 100 Index in the medium to long term if there had not been a referendum. On the other hand, I...
The anti-alcohol measures in Russia and life satisfaction
Baydadaeva, Nigina ; Fialová, Kamila (advisor) ; Opatrný, Matěj (referee)
1 Abstract The long-standing issue of the alcohol consumption level in Russia, remaining among the highest in the World, has resulted in the introduction of strict anti-alcohol regulations aiming to mitigate the negative aftermath. Substance abuse influences many spheres of life, including life satisfaction. Moreover, in the special case of Russia, hazardous drinking led to the increase in the probability of men's death. This thesis examines the relationships between the newly introduced anti-alcohol policies in Russia during the period from 2009 to 2014 and the life satisfaction of alcohol consumers. To perform the analysis, the Difference-in-Differences principle is applied to the sample derived from the two waves of the non-governmental survey conducted by The Russia Longitudinal Monitoring Survey - Higher School of Economics (RLMS-HSE). The respondents are divided into two groups: alcohol consumers (treatment group) and abstainers (control group). The analysis is firstly performed on the whole sample of the Russian population, then on the masculine subsample. The results of both parts of the analysis show no evidence of an increase in the life satisfaction of alcohol consumers following the implementation of the anti-alcohol regulations over the period under review. Keywords: taxes, life satisfaction,...
Competitive Balance in Individual Sports: An Empirical Evidence of Uncertainty of Outcome Hypothesis
Berčík, Václav ; Janhuba, Radek (advisor) ; Opatrný, Matěj (referee)
Beach volleyball is a fast-growing modern sport that is struggling with popularity despite being one of the most attractive-to-watch sports when directly compared to others at the Olympics. This thesis studies what drives fans' demand for watching professional beach volleyball. We use viewership data from YouTube live streaming of FIVB World Tour event - 2021 Katara Cup. In this thesis, we investigate the effect of uncertainty of outcome and both long and short-term determinants of team quality on fans' behaviour. The uncertainty is proxied by difference in odds, the long-term team quality is determined by teams' tournament seedings and short-term quality by recent winning records. The dynamics of fans behaviour according to the progress of the game are also studied. We are specifically interested in the effect of in-game uncertainty and surprising results on demand. Results of the work show evidence that beach volleyball fans prefer games with uncertain outcomes, care more about short-term team quality than long-term, and change behaviour in-game according to the development of uncertainty.
Modeling of football matches results and efficient-market hypothesis in sports betting
Augustin, Michael ; Korbel, Václav (advisor) ; Opatrný, Matěj (referee)
01 Abstract Betting on sporting events can be perceived by the general public as a game of chance. In the professional literature, however, betting on football matches is treated in the same way as other financial markets, where in the event of a violation of the theory of efficient markets due to the occurrence of inefficiency, there are opportunities for investors to obtain abnormal returns. The main goal of this work is to create a model capable of predicting the results of football matches on the basis of historical data better than bookmakers are able to do and test the effectiveness of the Czech betting market for football matches of the Czech highest football league. The first part of the thesis contains a more detailed presentation of the theory of efficient markets, a comparison of financial and betting markets and sources of possible inefficiency in betting markets. The second and third parts present data, models and their possible modification to increase the accuracy of estimates. The fourth part describes the results of testing individual models and subsequent simulations of betting strategies. The fifth part contains a conclusion and discussion of the results, including an indication of possible alternatives to follow-up research. The results of simulations of betting strategies confirm...
Health, Happiness and Consumption of Sugary Goods
Hanusová, Klára ; Ščasný, Milan (advisor) ; Opatrný, Matěj (referee)
Numerous studies have examined socio-economic and demographic determinants of sugar consumption, happiness, and life satisfaction. However, little is still known about association between sugar consumption on one side and happiness (or life satisfaction), on the other side, in particular, if we control for other key factors such as health, dietary patterns, or even addictive behaviour that all potentially affect both sugar consumption and life satisfaction. This thesis fills this research gap. Individual-level data obtained from the INHERIT multi-country survey are used to analyse these determinants in five European countries, the Czech Republic, Latvia, Portugal, Spain, and the United Kingdom. The analysis is relying on several econometric models for count and limited dependent variable data, including negative binomial, logit, multinomial logit, and bivariate probit. We found that younger, respondents with children, and in particular males are eating more portions of sugary goods. Higher consumption of sugary goods is also correlated with eating more meat and smoking, and bad health status, gastrointestinal disease in particular, that is likely consequence of these healthadverse habits. Many of the explanatory variables which are positively associated with sugar consumption, tend to have opposite...
Do National Hockey League Players Perform Better During Their Contract Years?
Liehman, Jan ; Opatrný, Matěj (advisor) ; Janhuba, Radek (referee)
This thesis analyses the validity of the contract year phenomenon in the Na- tional Hockey League (NHL). This notion, that players increase their perfor- mance in the final year of their contract, has been supported by previous find- ings in baseball and basketball, but ice hockey has been largely overlooked thus far. This thesis further extends the analysis to the second-to-last year on players' contract and distinguishes between unrestricted and restricted free agents. Rigorous analysis of the NHL contract structure is employed to elimi- nate contract states that would bias the results. By using a within-player fixed effects model in combination with advanced performance metrics, it arrives at an unexpected conclusion that upcoming unrestricted free agents improve their performance in the second-to-last year of their contract, but there is not enough evidence to suggest that they improve in the final one. No performance increase was found for upcoming restricted free agents during the final two years of their contract.
