【 摘 要 】

With farms cultivating tens or hundredsof thousands of hectares, Ukraine is often used todemonstrate the existence of economies of scale in moderngrain production. Panel data analysis for all thecountry's farms with more than 200 hectares in2001-2011 suggests that higher yields and profits are due tounobserved factors at rayon (district) and farm level ratherthan economies of scale. Productivity growth was driven notby farm expansion but by exit of unproductive and entry ofmore efficient farms. Higher initial shares of area underfarms with more than 3,000 or 5,000 hectares at the rayonlevel significantly reduce subsequent exit, suggesting thatland concentration reduces productivity growth. The paperdraws implications for global evolution of farm structures.
