OECD Ülkelerinde Vergi Takozu ve İşsizlik Arasındaki İlişkinin Analizi

Öz

Bu çalışma, vergi takozunun işsizlik üzerindeki etkisini OECD ülkeleri örneği üzerinden analiz etmeyi amaçlamaktadır. Vergi takozu; işverenin bir çalışanı istihdam etmek için katlandığı toplam işgücü maliyeti ile çalışanın net eline geçen ücret arasındaki farkı ifade etmektedir. Bu fark gelir vergisi, sosyal güvenlik primleri ve diğer zorunlu kesintiler gibi unsurlardan oluşmakta olup, işgücü üzerindeki mali yükü yansıtır. Yüksek vergi takozları işverenlerin istihdam maliyetini artırarak istihdam yaratma kararlarını olumsuz etkileyebilir ve işsizliğin yapısal boyutunu derinleştirebilir. Bu bağlamda çalışma, 2000–2023 dönemine ait panel veriler ışığında OECD ülkelerinde vergi takozu ile işsizlik oranları arasındaki ilişkiyi ampirik olarak incelemektedir. Westerlund ve Edgerton (2007) LM bootstrap eşbütünleşme ve Shin vd 1999 PMG modelleri kullanılarak yapılan analizler, OECD ülkelerinde vergi takozunun ve sosyal güvenlik katkı ödemelerinin işsizlik oranları üzerinde anlamlı ve pozitif bir etkisi olduğunu ortaya koymaktadır. Elde edilen sonuçlar, vergi politikalarının istihdam üzerindeki dolaylı etkilerini göz önünde bulundurarak daha dengeli ve istihdam dostu vergi reformlarının gerekliliğine işaret etmektedir.

Analysis of the Relationship Between Tax Wedge and Unemployment in OECD Countries

Öz

This study investigates the influence of the tax wedge on unemployment, focusing on the context of OECD member countries. The concept of the tax wedge encapsulates the gap between the full cost of labor borne by employers and the net earnings retained by employees after deductions for taxes and social security contributions. It serves as a critical indicator of the fiscal burden on labor and its potential distortionary effects on employment dynamics. This disparity comprises components such as income tax, social security contributions, and other compulsory deductions, collectively representing the fiscal burden placed on labor. High tax wedges may increase the cost of employment for employers, negatively affect their decisions to create jobs, and deepen the structural dimension of unemployment. Within this framework, the research conducts an empirical analysis of how the tax wedge correlates with unemployment levels across OECD member states, utilizing panel data spanning from 2000 to 2023. By integrating the LM bootstrap cointegration method developed by Westerlund and Edgerton (2007) with the Pooled Mean Group (PMG) estimator formulated by Shin et al. (1999), the study uncovers a statistically significant and positive association between unemployment rates and two key fiscal variables: the tax wedge and social security contributions. The findings suggest that increases in these labor-related costs consistently contribute to higher unemployment levels across the countries analyzed. These findings underscore the long-term distortionary effects of labor-related fiscal burdens on employment dynamics within the OECD context. These results highlight the importance of implementing more balanced, labor-market-friendly tax reforms that consider the indirect consequences of taxation on employment outcomes.
