GELİR DÜZLEŞTİRME HİPOTEZİ BAĞLAMINDA TÜRKİYE’DE VERGİ, ENFLASYON VE NOMİNAL FAİZ İLİŞKİSİNİN DEĞERLENDİRİLMESİ

Öz

Mankiw tarafından geliştirilen literatürde gelir düzleştirme hipotezi veya optimal senyoraj teorisi adlarıyla anılan teori, kamu finansmanı için enflasyonun kullanılması konusunda olumlu bir önerme olarak literatürde yerini almıştır. Teori, kamuya gelir yaratmak maksadıyla optimal maliye ve para politikası karması kullanıldığında enflasyon ve vergi oranlarının marjinal maliyetlerinin eşit olması gerektiğini, böylece gelir elde etmek amacıyla vergi oranlarının kullanılmasından veya enflasyondan kaynaklanan sosyal maliyetlerin en aza indirgeneceğini iddia etmektedir. Teoriye göre yüksek vergi oranları uzun dönemde yüksek enflasyon ve yüksek nominal faiz oranları ile ilişkilidir

EVALUATION TAX, INFLATION AND NOMINAL INTEREST RATES RELATION IN THE CONTEXT OF REVENUE SMOOTHING HYPOTHESIS IN TURKEY

Öz

Revenue smoothing hypothesis or optimal seigniorage theory, which was developed by Mankiw, has taken its place in the literature as a positive proposition to use inflation for public finance. The theory argues that when the optimal fiscal and monetary policy mix is used to generate revenue for the public, the marginal costs of inflation and tax rates should be equal, thereby minimizing social costs from using tax rates or inflation to generate revenue. According to the theory, high tax rates are associated with high inflation and high nominal interest rates in the long run period. The purpose of this study, in particular Turkey, to investigate the validity of the theory referred to as revenue smoothing hypothesis or optimal seigniorage theory in the literature. The validity of the revenue smoothing hypothesis for Turkey's economy, for the period 1985-2019, were tested using the tax rate, inflation rate and the nominal interest rate variables. Mankiw as claimed in revenue smoothing hypothesis, nominal interest rates, tax rates and inflation variables move in the long run period cointegrated and concluded that the hypothesis is valid for Turkey in particular the relevant period
