Abstract

This paper aims to analyze the validity of Wagner's Law for the period 1992-2021 in 83 countries by using Gengenbach, Urbain, and Westerlund (2016) panel cointegration and Augmented Mean Group Estimator (AMG) coefficient estimator methods. The paper uses per capita income and human development index to analyze the validity of Wagner's Law. The Results of the analysis indicate that Wagner's Law is valid in 26 of 86 countries. In 9 of these countries, the Wagner Law is valid both in terms of per capita income and human development index.

Wagner Kanunu’nun Geçerliliği: 1992-2021 Dönemi İçin Dünya’dan Kanıtlar

Abstract

Bu çalışmada Wagner Kanunu’nun geçerliliği, 83 ülke ve 1992-2021 dönemi için araştırılmaktadır. Ayrıca çalışma, Wagner Kanunu’nu kişi başı milli gelirin yanı sıra onu da kapsayan bir gösterge olan insani gelişme endeksi üzerinden test etmektedir. Gengenbach, Urbain ve Westerlund (2016) ve Genişletilmiş Ortalama Grup Tahmincisi yöntemlerinin kullanıldığı çalışmanın sonuçlarına göre; Wagner Kanunu, 86 ülkesinin 26’sında geçerlidir. Bu ülkelerden 9’unda ise Wagner Kanunu hem kişi başı milli gelire hem de insani gelişme endeksine göre geçerlidir.
