价格、利润、代理和生产
Prices, Profits, Proxies, and Production
摘要：
本文研究非参数识别和反事实界的异质性企业，可以排名的生产率。我们的方法适用于数量和价格是潜在的，使标准的方法不适用。相反，我们需要观察利润或其他优化值，如成本或收入，以及灵活选择的变量的价格或价格代理。我们扩展了经典的对偶结果，价格采取公司的设置与离散异质性，内隐，和有限的变化可能潜在的价格。最后，我们证明了非参数估计的收敛结果可以直接转化为产生集的收敛结果。
英文摘要：
This paper studies nonparametric identification and counterfactual bounds for heterogeneous firms that can be ranked in terms of productivity. Our approach works when quantities and prices are latent, rendering standard approaches inapplicable. Instead, we require observation of profits or other optimizing-values such as costs or revenues, and either prices or price proxies of flexibly chosen variables. We extend classical duality results for price-taking firms to a setup with discrete heterogeneity, endogeneity, and limited variation in possibly latent prices. Finally, we show that convergence results for nonparametric estimators may be directly converted to convergence results for production sets.
