Production shifting from China to Vietnam: Implications for Global Value Chains
Maderová, Karolína ; Semerák, Vilém (advisor) ; Vacek, Pavel (referee)
This thesis analyzes the importance of China within the global economy and assesses the potential of Vietnam to serve as its replacement, or at least for some industries. Using the network analysis and the hypothetical extraction method (HEM), the most influential sectors of the Chinese economy were identified and an increasing trend of reliance of the Westen countries on China's supply and demand was found. Next, using the trade decomposition method, the participation in GVC for Vietnam and China was calculated. Although Vietnam is increasing its participation and other countries are increasing their demand for inputs from Vietnam, based on the available data, it was not possible to determine whether these changes could mean that Vietnam can replace China in the future.

Measuring Air Transport Industry Linkages: Input-Output Analysis
Tax, Tomáš ; Semerák, Vilém (advisor) ; Macháček, Vít (referee)
This thesis examines linkages of the Czech air-transport sector to the rest of the Czech economy using the hypothetical extraction method (HEM) within the input-output analysis. In order to estimate air transport total linkages on the Czech economy together with linkages air transport has with its upstream and downstream industries, three different forms of hypothetical extractions using two input-output models (the Leontief and the Ghosh models) were applied on the World Input-Output Tables (WIOTs). The Leontief model enabled quantification of the total and backward (upstream) linkages, whereas the Ghosh model was used to measure forward (downstream) linkages of air transport. Moreover, upstream and downstream domestic industries, that would be hit the most by the extraction of air transport from the Czech economy, were identified using the corresponding models. The results of the research allow to estimate how the rest of the economy would be affected by the Czech air transport's shutdown (for example due to travel restrictions connected to the Covid-19 pandemic) and help to identify industries hit the most by such industry closure.
