Üretim fonksiyonuüzerine tartışmalar iktisatçıların daima ilgisini çekmiştir. Bu çalışmanınamacı, gelişmiş ve gelişmekte olan ülkelerde, Cobb-Douglas, CES ve VES üretimfonksiyonlarından hareketle, ölçek esnekliği,çıktı esnekliği ve ikame esnekliğini tahmin etmektir. Amaçdoğrultusunda, dört girdili (emek, sermaye, doğalgaz ve petrol) olacak şekildemodel oluşturulmuştur. Çalışmada 1982-2014 dönemine ait verilerle 22 gelişmiş,12 gelişmekte olan ülke için doğrusal ve doğrusal olmayan panel veri analiz tekniklerindenyararlanılmıştır. Cobb-Douglas üretim fonksiyonu’ndan elde edilen bulgular,sermayenin çıktı esnekliğinin gelişmiş ülkelerde, emeğin çıktı esnekliğinin isegelişmekte olan ülkelerde daha düşük olduğunu göstermektedir. Ayrıca doğalgaztüketimi çıktı esnekliği, gelişmekte olan ülke grubunda istatistiksel olarakanlamsız iken, petrol tüketimi çıktı esnekliğinin gelişmiş ülkelerde dahayüksek olduğu görülmüştür. CES üretim fonksiyonundan elde edilen bulgularagöre, emek ve sermaye arasındaki ikame esnekliği gelişmiş ülkelerde birdenbüyük, gelişmekte olan ülkelerde ise birden küçük olarak tahmin edilmiştir.

Discussions on theproduction function have always attracted the attention of economists. The aimof this study is to predict scale elasticity, output elasticity and elasticityof substitution for developed and developing countries, based on Cobb-Douglas,CES and VES production functions. Model has been created for four inputs(labor, capital, natural gas and oil). In the study, linear and nonlinear paneldata analysis techniques were used for 22 developed and 12 developing countriesby data for the period 1982-2014. Findings obtained from the Cobb-Douglasproduction function show that output elasticity of capital is higher indeveloped countries and output elasticity of capital is lower in developingcountries. Moreover, while the output elasticity of natural gas consumption wasstatistically insignificant in the developing country group, the outputelasticity of oil consumption was seen to be higher in developed countries.According to the CES production function, the elasticity of substitutionbetween labor and capital was estimated to be greater than one in developedcountries. Similarly, the elasticity of substitution between labor and capitalwas estimated to be smaller than one in developing countries.
