Doğal İşsizlik Oranı mı? İşsizlik Histerisi mi? Türkiye İçin Sektörel Panel Birim Kök Sınaması Analizi

Abstract

Bu çalışmada Türkiye’de sektörel işsizliğin doğal işsizlik oranı önsavıyla mı yoksa işsizlik histerisi önsavıyla mı açıklanabilir olduğu incelenmektedir. Bu amaçla Türkiye’deki 9 sektörün 1988-2008 dönemini kapsayan işsizlik oranı serilerinden oluşan panel veri seti oluşturularak, işsizlik serilerinin durağanlığı sınanmaktadır. Durağanlık, son dönemlerde geliştirilen ve her sektörde farklı tarihlerde ve farklı sayılarda kırılmaya izin veren bir panel birim kök sınamasıyla sınanmaktadır. Elde edilen sonuçlar diğer çalışma sonuçlarından farklı olarak Türkiye Ekonomisini oluşturan sektörlerin işsizlik oranlarının doğal işsizlik önsavının özel bir türü tarafından açıklanabilir olduğunu göstermektedir

Is Natural Rate of Unemployment or Hysteresis? Sector-Specific Panel Unit Root Test Analysis for Turkey

Abstract

In this study we investigate whether sector-specific unemployment in Turkey is explained by natural rate of unemployment or hysteresis hypothesis. We employ sectoral unemployment rate in nine Turkish leading sectors covering the period 1988-2008 and test the stationarity of unemployment rates. For the test we use a recently developed panel unit root test which allows for different number of structural breaks in unemployment series in different dates. Unlike the other studies, the results obtained in this study show that the sectoral unemployment can be explained by a special case of the natural rate of unemployment hypothesis

Keywords

• Natural unemployment rate, hysteresis, panel unit root test
