Abstract

Tanulmányunkban azt vizsgáljuk, milyen hatással vannak az Európai Unió Oroszországgal szembeni szankciós intézkedései, illetve az ezekkel kapcsolatos hírek a gázpiaci árakra. Az eseményhatás-elemzés módszerének alkalmazásával elsősorban arra kerestük a választ, hogy a szankciókhoz köthető különböző "hírtípusok" (szankciós csomag lebegtetése, tartalmának ismertetése, majd elfogadása) eltérő módon okoznak-e szignifikáns hatást a gáz tőzsdei árfolyamára. A 24 kiválasztott eseményt három különböző modellvariánssal (piaci modell, GARCH, EGARCH), négy különböző ablakhossz (3, 5, 10 és 15 napos) alkalmazásával vizsgáltuk. Eredményeink igazolták feltevésünket, miszerint a szankciók hírének lebegtetése már önmagában árfelhajtó hatású, hasonlóan a másik két hírtípushoz.
