Abstract: Product-level sale is crucial for estimating product productivity when input allocation is not observed. However, sales data are often incomplete. For example,  the combination of manufacturing surveys and customs dataset always provides detailed data on firm--level inputs and outputs, and the transaction of only exported products. To address this issue, we extend Valmari (2023) and Orr (2022) and to estimate product functions of multi--product firms with flexible-elasticity demand curves. Assuming a same CRS production function across products, we obtain the firm markup by the production approach developed by De Loecker (2012). These markups and observed sales are used to estimate the input allocation share for the corresponding product.
