Abstract: In this thesis, we study the return and volatility spillovers between forex and
stock markets in Scandinavian countries employing recently developed methodology of spillover indices. Those measures are based on forecast error variance
decomposition of generalized vector autoregressive (GVAR) model. This allows
us to estimate both total and directional spillovers. Moreover, frequency connectedness analysis is conducted by decomposing the spillover indices into frequency
bands, corresponding to short-, medium- and long-run connectedness. We used
daily data for major stock market indices and exchange rates of domestic currency towards US dollar for Norway, Sweden, Denmark and Finland. Our data
spans from February 2002 till July 2018 that covers turmoil periods of global financial crisis in 2007-2009, European sovereign debt crisis 2010-2013 and Brexit
referendum in mid 2016. Our empirical analysis reveals that Norwegian financial
markets do not contribute much to both return and volatility spillovers. On the
other hand, euro and Danish FX market perform very similarly, by exhibiting
the highest spillover contributions for both returns and volatility. Furthermore,
distinct increasing trends in spillovers are revealed during the turmoil periods for
most of the markets. From frequency connectedness analysis, we inspect high
short-run return connectedness for the whole period of time. For volatility, shortrun connectedness is prevailing over long-run in normal times, while the pattern
inverses during turmoil periods.
