OECD ÜLKELERINDE ARGE HARCAMALARI İŞGÜCÜ VERIMLILIĞI İÇIN ÖNEMLI MI? ÇÖZÜLMEMİŞ BİR SORU

Çalışmanın amacı, 22 OECD ülkesi için 1991–2003 dönemi verilerini kullanarak araştırma geliştirme harcamaları ile işgücü verimliliği arasındaki ilişkiyi panel veri yöntemleri kullanarak incelemektir. Bu amaçla, fiziki sermeye, bilgi sermayesi, beşeri sermaye ve emekten oluşan bir Cobb-Douglas tipi üretim fonksiyonu tahmin edilmiştir. Bu değişkenlere ilave olarak dış ticaret hacmi ve ARGE yayılımı kontrol değişkenlerinin eklendiği tahmin sonuçlarına göre işgücü verimliliği ile ARGE arasında pozitif bir uzun dönem esnekliği vardır. Bu sonuç, işgücü ve sermaye yoğunluğu değişkenlerinin dışarıda bırakıldığı alternatif bir model için de geçerlidir. Dışa açıklığı yansıtan dış ticaret hacmi değişkeni de bu modelde istatistiksel olarak anlamlı bulunmuştur.

Anahtar Kelimeler:

ARGE harcamaları, işgücü verimliliği, OECD, panel veri

DO R&D EXPENDITURES MATTER FOR LABOR PRODUCTIVITY IN OECD COUNTRIES? AN UNRESOLVED QUESTION

The aim of this study is to analyze the relationship between labor productivity and R&D expenditures. We have tested this relationship using a panel of 22 OECD countries that covers the period 1991-2003. ACobb-Douglas production function was estimated in growth form where physical capital, knowledge capital, human capital, and labor stock were included as the factors of production. The estimation results that also controlled for the effect of openness, and R&D spillovers implied a positive long-run R&D elasticity with respect to labor productivity growth. This result is robust to an alternative model where capital to labor ratio and labor variables are excluded. In this new model, the coefficient of the international trade variable included to account for openness was found to be positive.
