Gravity model for Czech Republic - Test of the effects of indirect trade / Gravity model for Czech Republic - Test of the effects of indirect tradeWlazel, Marek January 2014 (has links)
The aim of this thesis is to incorporate the effects of the indirect trade into the gravity model for Czech Republic. Using data from the recently released OECD-WTO TiVA database, a panel of 56 countries in 5 years between 1995 and 2009 is constructed. The traditional approach of estimating the log- linear form of the equation is questioned and in line with current academic research, the Poisson Pseudo Maximum Likelihood method is applied. The empirical analysis does not reveal any unambiguous effect of adjusting the gross exports for their foreign content; it rather confirms that Czech ex- ports are significantly driven by the demand for German exports and finds that they are the higher the greater is the share of services value added. Furthermore, it is found that the destination of Czech exports is not signif- icantly determined by target country's participation in global value chains.

The Effects of Participation in Global Value Chains : A Study of the Effects of Participation in Intermediate Trade on the Value Added Through Services and the Relative Demand for Skilled Workers in the Swedish Manufacturing IndustryHöijer, Anna Maria January 2023 (has links)
This study aims to investigate the effects of the integration in global value chains on the specialization in the production of services and the relative demand for high-skilled labor in the Swedish manufacturing industry. The empirical model and the predictions are based on theories and findings such as the phenomenon of servicification, the Hecksher-Ohlin theorem, and the Stolper-Samuelsson theorem. The study is conducted using a regression analysis of panel data and employs a fixed effects model to control for unobserved heterogeneities between the entities. An interaction variable based on the initial ICT capital stock of each sector is used in an attempt to establish causality. The results show that there is a positive and significant correlation between the growth of intermediate imports and the growth value added through total services and business services between 2000 and 2018. The results also display a positive and significant correlation between the growth of intermediate trade and the value added through total services between 1995 and 2018. The direction of causality of the relationships are not established. Furthermore, the results for growth of relative employment and relative wage are insignificant. Based on these findings it is concluded that there is a correlation between increased participation in global value chains and the growth of value added through services.
