DESCRIPTION;ENCODING=QUOTED-PRINTABLE:<p style="text-align: justify;"><strong><span style="font-family: 'Calibri'

 strong><strong><span style="font-family: 'Calibri','sans-serif';">Heterogen
 eous is Productivity?</span></strong></p><p style="text-align: justify;">Ab
 stract:</p><p style="text-align: justify;">We show that existing practices 
 for estimating production functions suffer from a fundamental non-identific
 ation problem due to flexible inputs, such as intermediate inputs. Using a 
 transformation of the firm’s first order condition, we develop a new identi
 fication strategy and propose a simple nonparametric estimator for the prod
 uction function and productivity. We show that the alternative of approxima
 ting the effects of intermediate inputs using a value-added production func
 tion does not solve the identification problem. Applying our approach to pl
 ant-level data from Colombia and Chile, we find that a gross output product
 ion function implies fundamentally different patterns of productivity heter
 ogeneity than a value-added specification.</p>
