The Impact of Natural Disasters on Access to Finance
Pavlovská, Markéta ; Horváth, Roman (advisor) ; Janásek, Lukáš (referee)
The intensity and destructiveness of natural calamities has increased in recent years. This thesis examines the causal effect of natural disasters on firm's access to finance across countries. Only largest catastrophes from years from 2003 to 2020 are considered. Data from the International Disaster Database and World Bank databases are matched into two time dimensional panel data set consist- ing of firms from 21 countries. The effects of natural disasters are analyzed by difference-in-differences method and the regression is estimated by Ordinary Least Squares and Fixed effect. The model is then subjected to various robust- ness checks to assess the validity of the results obtained. The overall results suggest positive response of firm's perception of access to finance 1 to 3 years after the occurrence of natural disaster. 1

Numerical fiscal rules and fiscal institutions in an economy with a dynamic common pool problem
Janásek, Lukáš ; Gregor, Martin (advisor) ; Hejlová, Hana (referee)
1 Abstract The focus of this bachelor's thesis is fiscal policy of a fragmented government that represents symmetric socio-economic groups. For the analysis of fiscal policy, I develop the model of a dynamic common pool. In the model, the fiscal choices of interest are 1) a level of tax revenue, 2) a level of public productive spending and 3) an intertemporal choice of a level of group's consumption spending. For each of the fiscal decisions, I describe a distortion associated with the fiscal choice stemming from the decentralized decision making. Next, I examine the impact of a deficit ceiling and fiscal institutions that centralize separate fiscal choices of groups on the three distortions. Due to the symmetry of groups, the analysis abstracts from the efficiency-equity trade-off. Among the key results is that three fiscal frameworks can attain the socially desirable fiscal policy: 1) centralization of the productive spending and the tax revenue combined with a deficit ceiling, 2) centralization of the consumption spending, 3) centralization of a budget size and the productive spending.

Acquisition of Costly Information in Data-Driven Decision Making
Janásek, Lukáš ; Baruník, Jozef (advisor) ; Vácha, Lukáš (referee)
This thesis formulates and solves an economic decision problem of the acquisi- tion of costly information in data-driven decision making. The thesis assumes an agent predicting a random variable utilizing several costly explanatory vari- ables. Prior to the decision making, the agent learns about the relationship between the random variables utilizing its past realizations. During the deci- sion making, the agent decides what costly variables to acquire and predicts using the acquired variables. The agent's utility consists of the correctness of the prediction and the costs of the acquired variables. To solve the decision problem, the thesis divides the decision process into two parts: acquisition of variables and prediction using the acquired variables. For the prediction, the thesis presents a novel approach for training a single predictive model accepting any combination of acquired variables. For the acquisition, the thesis presents two novel methods using supervised machine learning models: a backward es- timation of the expected utility of each variable and a greedy acquisition of variables based on a myopic increase in the expected utility of variables. Next, the thesis formulates the decision problem as a Markov decision process which allows approximating the optimal acquisition via deep...
