Sex, Drugs, and R&D: Missing Innovation from Regulating Female Enrollment in Clinical Trials with Valerie Michelman
Abstract: Did women’s underrepresentation as research subjects depress female-focused drug innovation in the late 20th century? From 1977-1993, U.S. regulatory guidance was that early-stage drug trials should not enroll pre-menopausal women. This guidance increased development costs and uncertainty for drugs targeting predominantly female diseases. We find that the 1993 removal of this guidance led to a large and sustained increase in female-focused drug patenting: the share of drug patents with a female focus increased 1.5-2 percentage points (38-51%). Our estimates imply 200-268 fewer female-focused drug candidates entered development during the guidance period, 17-58 of which would have been approved but for the exclusionary guidance.

Consumer-Financed Fiscal Stimulus: Evidence from Digital Coupons in China with Jing Ding, Lei Jiang & Matthew Notowidigdo
Abstract: Beginning in 2020, local governments in China issued digital coupons to stimulate spending in targeted categories such as restaurants and supermarkets. We study this new form of fiscal stimulus using detailed data from a large e-commerce platform and a bunching estimation approach, and we find that the coupons caused large increases in spending of 3.5-3.6 yuan per yuan spent by the government. We find no evidence that the large spending effects come from substantial substitution away from non-targeted spending categories or short-run intertemporal substitution. To rationalize these results, we develop a dynamic consumption model to show how the coupon’s minimum spending thresholds (i.e., “spend at least ¥X, get ¥Y off”) create temporary notches that lead to large behavioral responses. In the model, the increased spending caused by the coupons is partially “consumer-financed”, since consumers use their own money to push their spending above the coupon thresholds. Calibrating the model to match our empirical results, we find that coupons generate about half of the increase in consumer welfare as an equivalent amount of government spending distributed as cash, but that coupons are a much more cost-effective form of targeted fiscal stimulus .

Decreases In Readmissions Credited To Medicare’s Program To Reduce Hospital Readmissions Have Been Overstated with Christopher Ody, Leemore Dafny, David Grabowski & David Cutler. Health Affairs, January 2019. Vol. 38, Issue 1.
Abstract: Medicare’s Hospital Readmissions Reduction Program (HRRP) has been credited with lowering risk-adjusted readmission rates for targeted conditions at general acute care hospitals. However, these reductions appear to be illusory or overstated. This is because a concurrent change in electronic transaction standards allowed hospitals to document a larger number of diagnoses per claim, which had the effect of reducing risk-adjusted patient readmission rates. Prior studies of the HRRP relied upon control groups’ having lower baseline readmission rates, which could falsely create the appearance that readmission rates are changing more in the treatment than in the control group. Accounting for the revised standards reduced the decline in risk-adjusted readmission rates for targeted conditions by 48 percent. After further adjusting for differences in pre-HRRP readmission rates across samples, we found that declines for targeted conditions at general acute care hospitals were statistically indistinguishable from declines in two control samples. Either the HRRP had no effect on readmissions, or it led to a systemwide reduction in readmissions that was roughly half as large as prior estimates have suggested.
