In this study, 5 different econometric models are constructed by determining the variables affecting food price increases in Turkey. Monthly data for the years 2005-2023 are used. The coefficients of the models are estimated by Dynamic Least Squares method. TUFE_GIDA (food and non-alcoholic beverages series), TUFE_IMG (CPI unprocessed food series)...

Since threshold autoregressive models were discovered, many unit root tests have been developed to test the unit root null hypothesis when considering regime change. On the other hand, Sollis, J Time Ser Anal 25:409–417, 2004, indicates that a threshold unit root test could be combined with some smooth transition logistic functions which are introd...

This study aims to explore the effects of election periods on the economy from the perspective of the “public choice theory”. We selected our variables from among those focused by the research that examine elections from the standpoint of political business cycles; i.e., exports, Gross Domestic Product (GDP), Wholesale Price Index(TEFE), the number...

This study examines the relationship of energy consumption per capita with growth rate, industrialisation, trade volume and urbanisation in Turkish economy throughout the 1980–2015 period using the Engle-Granger, Fully modified ordinary least squares (FMOLS), canonical cointegration regression (CCR) and dynamic ordinary least squares (DOLS) methods...

Bu çalışmanın amacı, Mehmet Caner ve Bruce Hansen tarafından 2001 yılında geliştirilen eşik birim kök testinin yapısal kırılma altında birinci tip hata olasılıklarında (BTHO) meydana gelen bozulmaları Monte Carlo çalışmaları ile ortaya koymak ve elde edilen sonuçları Cook ve Manning (2004) çalışmasında Enders ve Granger (1998) eşik birim kök testi...

Bu çalışmanın iki amacı vardır. Birincisi, Taylor kuralı ve Faiz Düzleştirme kuralından yararlanarak, kısa vadeli faiz oranı değişkeninin bağımlı; enflasyon ve çıktı açığı değişkenlerinin, bir dönem önceki kısa vadeli faiz oranı değişkeninin bağımsız değişkenler olarak yer aldığı bir ekonometrik modeli tahmin etmektir. Bu amaçla değişkenlerin 2000(...

This study aims to reveal the causality relations between the macro aggregates that affect current deficit using conditional and partial Granger causality test. Current deficit/GDP, growth rate, real effective exchange rate, direct foreign capital investment, openness, and energy import were selected as variables for this purpose. 2003.1-2014.2 qua...

This study aims to examine the relationship between the current account deficit and economic growth in Turkey. For this purpose, Granger causality and VAR analyses were performed on the variables by using their quarter data for 1999:01 - 2014:02. Granger causality test revealed a unidirectional correlation from growth rate to current account defici...

The concept of Expectations is one of the most important developments in the last 50 years of Economic Theory. On the other hand, the popularity of nonlinear modeling techniques used in econometric studies has been increasing. In this study, Adaptive and Rational Expectation models are analyzed within the framework of nonlinear Threshold Regression...

This study aims to explore the relations between bank credit risks and macroeconomic factors.
