This paper studies the dynamics of volatility transmission between Central European currencies and euro/dollar foreign exchange using model-free estimates of daily exchange rate volatility based on intraday data. We formulate a flexible yet parsimonious parametric model in which the daily realized volatility of a given exchange rate depends both on its own lags as well as on the lagged realized volatilities of the other exchange rates. We find evidence of statistically significant intra-regional volatility spillovers among the Central European foreign exchange markets. With the exception of the Czech currency, we find no significant spillovers running from euro/dollar to the Central European foreign exchange markets. To measure the overall magnitude and evolution of volatility transmission over time, we construct a dynamic version of the Diebold-Yilmaz volatility spillover index, and show that volatility spillovers tend to increase in periods characterized by market uncertainty.

In this paper, the informative value of firm capital structure is analyzed. In the first part, a theoretical background regarding capital structure theories is presented. In the second (empirical) part, the Ohlson (1995) valuation framework is used in order to analyze the informative value of firm capital structure on a sample of data for the Czech (non-financial) companies. A contextual approach is adopted and the value relevance of debt is analyzed considering the signalling and the optimal capital structure theories. According to the results and in accordance with the optimal capital structure theory, debt is more penalized in case of the companies that deviate from the target debt level. Moreover, debt proves to be a positive signal for the firms with a higher earnings growth potential. This, in turn, is consistent with the signalling theory.
