On the Link between Spot and Forward Power Prices: A Comparative Analysis of German and Hungarian Power Market Efficiency
Harnych, Pavel ; Krištoufek, Ladislav (advisor) ; Doležel, Pavel (referee)
This thesis examines the impact of shocks in spot prices on long-term forward contracts in power markets. A unique comparison of efficiency of German and Hungarian power markets is provided. The risk premium on week-ahead forward contract is scrutinized by both data inspection and by unbiased forward rate hypothesis (UFRH) testing. Additionally, the ex-post market's prediction error for this product is explained by main drivers of spot electricity price, which are presented in section devoted to introduction to power markets. Expectedly, Hungarian forwards with longer time-to-delivery are found to react heavily on spot market shocks after controlling for changes in short-run marginal costs of conventional power plants. Such outcome applies both to intra-day and weekly time horizons. However, this evidence was not found for German market. These results point out to immaturity and the presence of inefficiencies in Hungarian power market. However, Hungarian risk premia on week-ahead and day-ahead forward products turn out to be considerably lower than for Germany. This was confirmed by UFRH tests on week-ahead forward contracts, where a significant risk premium was found in Germany as opposed to Hungarian risk premium. This finding is surprising since Hungarian spot prices are more prone to upward...

Credit Euroization in the New EU Member States: Causes, Consequences and Some Lessons from Hungary
Harnych, Pavel ; Holub, Tomáš (advisor) ; Hausenblas, Václav (referee)
This thesis examines issues related to the sharp surge in credit denominated in foreign currency (FX) in the New EU Member States before the advent of the recent crisis. We commence with the introduction of some stylized facts as well as decisive determinants of credit euroization, including the exchange rate regime. Subsequently, the economic performance and soaring volume of non-performing loans during the crisis are found to be adversely related to previous FX credit growth. Furthermore, we discuss some challenges, which are faced by the monetary authority of a credit euroized economy. Next, we construct a distinctive index on currency mismatch adjusted for unhedged borrowers, which appears to be significantly associated with country risk premia. The final chapter is devoted to the recent materialization of vulnerabilities connected to FX lending in Hungary. The sensitivity of this economy to exchange rate movements is illustrated by strong correlation between CDS spread and relevant exchange rates. Additionally, we scrutinize the latest version of controversial government schemes designed to mitigate the negative balance sheet effect on households indebted in FX. A unique estimation of the long-term costs of a CHF mortgage in comparison to a forint mortgage loan is provided. The impact of...
