Abstract

Two functional forms (Translog and Cobb-Douglas) were applied for estimation of grapes (vine) production function and thereby evaluation of RETURNS TO SCALE with 90 observations. Also, RETURNS TO SCALE under various conditions, namely, “using added fertilizers and labors”, “no added fertilizers and labors”, “only using added fertilizers” and “only using added labors” were studied. Results indicate that TRANSLOG PRODUCTION FUNCTION is better than COBB-DOUGLAS PRODUCTION FUNCTION to determinate RETURNS TO SCALE. Results to scale showed that farmers would have highest RETURNS TO SCALE, if they use added fertilizer. In this case, increasing RETURNS TO SCALE was observed (returns to scale was 6.39). But if farmers do not use added fertilizers and labors, would have decreasing RETURNS TO SCALE.
