An analysis of the sources of import growth in Turkey: 1985-90
(1995) Celasun, Oya
The sources of import growth in Turkey during the 1985-90 period are decomposed into four casual factors domestic demand expansion, export expansion, import substitution and technological change, using the inputoutput framework. Domestic price indices for imports and gross output were constructed, and the 1990 input-output table was double deflated into constant 1985 prices. The decomposition results are analyzed within the context of the economic conditions in Turkey during the period. It is observed that the structure of the causal factors have changed compared to the previous period of 1979-85. The contribution of export expansion is observed to be negligible, and domestic demand expansion and import substitution are the most prominent sources of import growth between 1985 and 1990.

Time frequency representation and its economic applications
(2009) Akkoyun, Hüseyin Çağrı
This thesis analyzes real oil price crises and US output gap by using time frequency representation. Firstly, time frequency representation is introduced by giving some basic definitions, formulations and illustrative examples. After that, frequency characteristics of demand-side driven and supply-side driven real oil price shocks are analyzed. Also, frequency characteristic of US output gap is analyzed by dividing the output gap series in three parts.

Two essays on dynamic macroeconomics
(2001) Taşçı, Hakan
First chapter of this research assesses the stability of the money-income relationship for seven OECD countries by using the data from 1960’s to 2000’s. The short run relationships between monetary policy and output have strong evidences. When the sample was split into two sub samples: pre and post 1980, the empirical evidence presented in this research shows that even if the inferences gathered across countries are not always parallel, the inferences gathered from the VAR specification across the samples for each country are mostly parallel. In this article secondly, by using the 1990 input-output table, the inflationary effects of crude oil prices are investigated for Turkey. Under fixed nominal wages, profits, interest and rent earnings, the effect of increasing prices of oil on inflation is limited. However, when wages and the other three factors of income (profit, interest and rent) are adjusted to the general price level that includes the oil price increases, then the inflationary effect of oil prices becomes significant. Hence, indexation could have very severe effects on an economy when oil prices increase.
