Address: Arklių str. 18, Vilnius, Lithuania. Supervisor: Prof. dr. Valdonė Darškuvienė (ISM University of Management and Economics, Social Sciences, Economics, S 004) About Doctoral Dissertation: One of the reasons of the rising importance of the intermediate production networks – increased trade in intermediate production and international fragmentation of production chains. Network analysis helps to understand the different ways the economy is interconnected in order to capture possible spillovers and to ensure the timely and effective authorities’ reaction and support. This dissertation is developed in four papers which aim is to investigate the origins of aggregate fluctuations via the lens of intermediate production network and to assess its impact on the transmission and propagation of macro and micro shocks. The theoretical model is developed to obtain insights into the propagation of macro technology shocks through input-output linkages. Regarding micro and macro technology shocks, the empirical counterparts are developed and estimated with US industry-level data of 385 industries. Results suggest that technology shocks have a positive impact on sectors’ output growth directly and indirectly via the network downstream linkages. Regarding the network origins of aggregate fluctuations, the first evidence is provided that the Lithuanian intersectoral network is an important propagation channel for sectoral shocks (analyzing linkages between ~60 sectors). In terms of global linkages, results indicate the potential role of sectoral linkages as a transmission mechanism of shocks to the global economy (analyzing linkages between more than 2290 sectors). Defense board members Chairperson:Prof. dr.
