Before revision: Partial identification approaches have seen a sharp increase in interest in econometrics due to improved flexibility and robustness compared to point-identification approaches . However, formidable computational requirements of existing approaches often offset these undeniable advantages---particularly in general instrumental variable models with continuous variables .
