This thesis studies how the investor attention proxied by Google search volume affects different aspects of market behavior. My results show that a surge in online attention is associated with an increase in trading activity and stock price volatility, but no effect is detected for daily returns. Yet, if market sentiment is taken into account, the relationship comes to the surface for returns as well. The returns tend to decrease with attention hikes in negative sentiment periods and the opposite is observed for periods of positive sentiment, suggesting that Google web search captures predominately attention of sentiment investors. Moreover, I demonstrate that with the outburst of financial crisis, the interdependence between attention and trading activity was intensified. Lastly, I provide evidence that web search may shed some light on IPO-related puzzles. The initial returns seem to be higher for IPOs that receive above average attention, and are likely to be reversed in long-term. In addition, it is ascertained that web search volume may act as a proxy for market overreaction to the offerings. Powered by TCPDF (www.tcpdf.org)

The thesis deals with manifestations of lexical dynamics in the language of Internet discussion forums. The chosen communication sphere is typical for its creativity and spontaneity, respectively active exchange of lexical means and the effort for fresh expressions. For these reasons, the language of discussion forums on the Internet is a suitable material basis for the confrontational description of lexical innovations in contemporary Bulgarian and contemporary Czech. The theoretical part of the thesis defines the notion of neologism and the terms connected with it, as well as the specific features of Internet communication. In the practical part, a structural and semantic analysis of Czech and Bulgarian neologisms is carried out, and considering that a large part of the new lexicon used in the discussion forums is borrowed mainly from English, more attention is paid to the interpretation of the meaning of these loanwords and the ways of their adaptation in Czech and in Bulgarian.
