摘要：This study explores the impact of technical inefficiency on agricultural supply functions inUkraine. Two models using a system of output supply and input demand equations wereevaluated in this research: one without inefficiency included in the model and another withinefficiency included. A likelihood ratio test found that the model with inefficiency includedwas the preferred model in this case. Incorporation of inefficiency into the model increasedoutput supply elasticities and did not dramatically change input demand elasticities. The own-price elasticities for grains, sugar beets, sunflowers, and potatoes showed inelastic positive signsthat were statistically significant. The own-price input demands were negative and also inelastic;however, only fertilizer and fuels were statistically significant.
