Natural Resource Curse and Shadow Economy: Emprical Evidence
Chen, Anna ; Horváth, Roman (advisor) ; Janda, Karel (referee)
The study aims to investigate the impact of natural resource wealth on the shadow economy. The theoretical section provides the basis of understanding the nature of two phenomena and discusses the possible transmission channels through which natural resources might influence the shadow economy. Consequently, the key determinants of the shadow economy are examined by static and dynamic models. Natural resource abundance is proxied by natural resource rents. We employ a panel data set for 109 countries for the period from 1996 to 2006. The results reveal that resource wealth is associated with the decrease of the shadow economy. This result is robust for different resource types (durable and non-durable), and the effect is more profound for countries with a low income level.

Monetary Policy Transmission - Bank Lending Channel and Banking Market Structure. The Case of Georgia, Azerbaijan, and Armenia.
Jvaridze, Tinatin ; Mareš, Jan (advisor) ; Komárek, Luboš (referee)
In the thesis, we examine the bank lending channel and the effect of banking market structure on the transmission of monetary policy in Georgia, Armenia, and Azerbaijan. We employ bank-level data for the period of 2011-2017 to detect if banks with different characteristics react differently to monetary policy shocks. Banking market structure is proxied by three measures-CR5, HHI, and Lerner Index. We estimate two types of models: dynamic (with system GMM) and static (with FE) models. We also consider the effect of dollarization on bank loan supply as well as on monetary policy. We do not find consistent evidence that banks react differently to monetary policy shocks depending on bank characteristics (size, capitalization, and liquidity). Hence the existence of the lending channel is not conclusive. Nevertheless, the results show that monetary policy is less effective in more concentrated markets. This finding is robust in all specifications with both types of models. In this sense, competition is not significant. The results also suggest that dollarization weakens the effect of domestic monetary policy.
