This dissertation comprise of four essays. The first essay studies the relationship between treasury auction maturity and auction interest rates. Using the Turkish auction data from 1988 to 2004, a reciprocal linkage between auction interest rates and maturities is observed, especially for the 1995-2000 period. This suggests that under an adverse shock, treasury decreases the auction maturity in order not to increase interest rates too much. A change in this reciprocal relationship is also reported for the post-2001 era. The second essay assesses the effect of USD-Euro parity on a small open economy for an economy where its exports are predominantly denominated in Euros and imports are denominated in USD. The empirical evidence suggests that a positive innovation in USD-Euro parity appreciates the local currency, decreases inflation and increases output. The third essay studies the relationship between on-budget and off-budget expenditures in Turkey and concludes that information content of the budget deficit statistics is not empty; however, it might be misleading in assessing fiscal stance for Turkey. The final essay investigates the connection between Turkish industrial production performance and the success of a popular Turkish football team, namely Fenerbahce. The success of Fenerbahce is interpreted as a proxy for the workers' mood or morale. Performing a transfer function analysis on my monthly data set, I reveal a positive feedback from Fenerbahce's success, which proxies workers' mood/morale, to economic performance. Evidence of the effects of games against domestic rivals on industrial performance is not statistically significant.
