Rare Disasters and Asset Pricing Puzzles
Kotek, Martin ; Maršál, Aleš (advisor) ; Korbel, Václav (referee)
The impact of rare disasters on equity premium and term premium in a New Keynesian DSGE model is explored in the thesis. Andreasen's (2012) model with Epstein-Zin preferences, bonds and a rare disaster shock in total factor productivity process is extended by a variable capital stock and an equity-type asset. We find that the variable capital significantly changes behavior of the model, capital depreciation must be substantially increased to counter the effect of variable capital and stochastic mean of inflation increases. The model calibrated to the US economy and a high risk aversion generates 10-year term premium of 90 basis points, rare disasters increase the premium only by 3 basis points. The equity premium is 163 basis points and rare disasters increase it also only by 3 basis points. The model with a low coefficient of relative risk aversion of 5.5 generates negative risk premia. Rare disasters increase the risk premia by mere 4 basis points in comparison to a model with i.i.d. shocks. Powered by TCPDF (www.tcpdf.org)
Children and cheating - A field experiment with individuals and teams
Korbel, Václav ; Chytilová, Julie (advisor) ; Mlčoch, Lubomír (referee)
This thesis presents a field experiment drawing interferences on the lying be- havioural patterns among grammar school students. Students were filling in non-related questionnaire for which they were rewarded. They rolled a dice and for a corresponding number on a dice they obtained a certain number of sweets. Students were not controlled therefore they could choose what num- ber to report. The experiment included one treatment for individuals and two treatments for groups. The analysis shows that a certain fraction of students cheated but they often did not exploit the possibility of cheating maximally. Older students cheated more in comparison with younger students and younger students deceived more in groups. Last but not least, dishonesty in groups may also hinge on the family background, namely on the number of siblings. The model of self-concept maintenance explains the cheating patterns observed in our experiment best among all discussed models. 1
How do people perceive income inequality? A Czech case
Havelková, Kateřina ; Korbel, Václav (advisor) ; Želinský, Tomáš (referee)
The widespread concern that the gap between the rich and the poor is continuously ex- panding prompts the stimulus for further examination. Standard theory suggests that the level of income inequality has a significant effect on policies with redistributive elements. However, empirical studies propose that rather than the actual shape of income distri- bution, individual perceptions of income distribution define the public finance models. Individuals tend to misperceive income inequality, yet there is little evidence regarding the origins of these perception biases. The bachelor thesis examines one of the possible theories that attempt to explain roots of misperceptions. The geographic reference group theory suggests that people project their local findings onto their estimates of overall income inequality. To test this hypothesis, we used the Gini coefficient with respect to country's districts as an explanatory variable and the subjective inequality index (Per- ceived inequality index) as a dependent variable. The empirical findings, nevertheless, provide little support for the geographic reference group theory as all regressions showed a highly insignificant relationship between district inequality and perceived inequality. The evidence suggests that respondents, who live in districts with high...
Ukrainian labour migration and remittances in the European Union
Šperková, Lenka ; Strielkowski, Wadim (advisor) ; Korbel, Václav (referee)
The remittances or money transfers sent by migrants to the country of origin are considered to be one of the welfare channels with potential to influence macroeconomics indicators. The aim of this thesis is to analyse migration and remittance behaviour of Ukrainian migrants in the context of the EU. Study is based on the questionnaire survey inspired by the similar projects in the Latin America and Mexico. Contribution of the thesis lies in the detailed analysis of the topic that separates different forms of remittances. The econometric model consists of statistical summary of the data and three hypotheses tests focusing on the probability and amount remitted; consumption behaviour and probability of getting skilled position. According to findings, probability and amount remitted is determined by demographic factors and direction of effects differs in the case of regularly and one- time payments. Altruism and business financing are primary motives to remit. Remittances appear to be transferred by informal channels into the productive forms of consumption. A procurement of skilled position is positively influenced by human capital factors but also reflects labour market situation in the destination country.

Working from home: the possibility or necessity?
Grossmann, Jakub ; Korbel, Václav ; Münich, Daniel
The study describes the use of work from home across socio-demographic groups in the Czech Republic during the coronavirus year 2020. It shows how work-from-home arrangements relate to workers' characteristics, such as their education, industry, gender, and type of household. The analysis reveals the perceived barriers to and benefits of working from home.
Social status in Vocational Education and Training (VET) in the Czech Republic over the past 15 years, and an international comparison
Korbel, Václav ; Münich, Daniel
The Czech Republic (CZ) has an historically strong system of vocational education and training (VET), which around 30% of first-year high school (HS) students enter each year. How many students should enter VET has often been debated. However, which students select into VET and how their composition has changed over time has been less examined. This study maps these phenomena by measuring the social status linked to VET programs in the Czech Republic since 2003. Based on previous literature, we define social status as the relative difference in PISA scores of first-year VET students compared to first year students at other types of high schools. The social status thus reflects which students chose VET, and is the sum of various factors that influenced their choice – the expected quality of education, employment prospects after graduation, and the perception and opinions of parents and primary school classmates. If the relative PISA scores of VET students decreased in comparison to those of students who entered other types of high schools from one PISA wave to another, we can interpret this as a decrease in the social status of VET students.
How should the government’s crisis measures be communicated? Through frequent repetition
Korbel, Václav ; Novák, Vladimír ; Šoltés, Michal ; Tóth, L.
About three weeks after the first case of Covid-19 infection in the Czech Republic was confirmed, i.e. on 20th - 21st March, we carried out a survey to find out how the way government measures are communicated affects residents’ willingness to abide by them. Our main findings were published in IDEA anti COVID-19 study # 7. We supplemented our questionnaire with an experiment in which we provided five different pieces of information\nabout the government measures to five randomly selected groups of people. This study focuses on presenting the results of that experiment.
Households’ attitudes to infection and to the government measures: the latest survey data
Korbel, Václav ; Novák, Vladimír ; Šoltés, Michal ; Tóth, L.
This study presents Czech people’s real views about the Covid-19 pandemic from a survey carried out on a representative sample of internet users around the 20th March 2020. It thus presents very up-to-date information about people’s attitudes to the ongoing infection and, moreover, to the measures imposed by the government. The findings provide new and important information to be taken into account when planning further measures. For example, if people had not considered the restrictions on free movement or the requirement to wear face masks as appropriate and had not begun implementing them voluntarily, the relevant authorities would have had to enforce these measures. More than half the population is concerned that they will catch the coronavirus. People have substantial confidence in the ability of the government measures to successfully overcome the current situation. The majority of people, around 75 %, declare themselves willing to limit their outdoor movements to essential activities and otherwise stay at home. Even so, almost 53 % of respondents go out every day. If it were to be necessary, many people are prepared to refrain from outdoor and social activities even for months. People believe that there is a moderately high chance of meeting an infected person on the street. Wearing face masks became a matter of course very quickly. 92 % of people only leave their homes with a face mask on, the majority agree that people without face masks should not be allowed into public areas, if they meet someone without a face mask, 42 % of respondents are prepared to tell the person concerned that they should wear a mask and a quarter would express their disapproval by frowning at that person.5 Another study will follow soon after this one, which reveals how reminders about government orders and recommendations (to wear face masks and practice social distancing) affect people’s willingness to abide by them and how the way the measures are communicated affects that willingness.

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...
The Covid-19 pandemic and socio-economic inequality in education
Federičová, Miroslava ; Korbel, Václav
In response to the Covid-19 pandemic, schools have been closed since 11th March 2020 and have been obliged to switch to remote teaching. This new situation may, among other effects, further deepen the considerable existing inequalities in education, which are already higher in the Czech Republic than in most other European countries. In this study, we look at various factors that may affect how remote teaching can be related to socioeconomic educational inequalities in the Czech Republic. For the sake of clarity, we distinguish between factors relevant to schools, families, and pupils. The aim of this study is not to describe the current situation but to outline who is most at risk of losing out as a result of remote teaching and where possible measures should be targeted in order to prevent deepening inequalities in education further. In this study, we focus on primary and lower secondary schools, with an emphasis on the lower secondary years.
