The Contribution of the Publicly Funded R&D Capital to Productivity Growth and an application to the Greek food and beverages industry

This paper follows the dual cost function methodology and develops a theoretical specification that assesses the contribution of public R&D capital to the productivity growth. The empirical application focuses on Greek food and beverages industry. For this purpose it employs a micro-aggregated annual data set over the period 1976-2002. The regression analysis shows that publicly funded R&D capital is a productive input as 8.7 percent and 7.3 percent of the total factor productivity growth in the food industry and in the beverages industry respectively is attributed to the publicly funded R&D capital. The relationship between publicly funded R&D and private purchased inputs is also examined.
