Physician-Induced Demand: Evidence from China’s Drug Price Zero-Markup Policy

Hanming Fang, Xiaoyan Lei, Julie Shi, Xuejie Yi, Aug 11, 2021

We exploit the staggered rollout of China’s drug price zero-markup policy (ZMP) to study physician-induced demand in healthcare. Our results show that the drug expenses in the treatment hospitals dropped by 63 log points (47 percent) compared with those of the control group; however, the expenses for non-drug services were 28 log points (32 percent) higher in the treatment group than in the control group. Our results provide robust evidence for physician-induced demand.

Focusing on China’s accession to the World Trade Organization, we show that Chinese cities with more exposure to trade liberalization sent more students to US universities.

Corporate Innovation and IPO Interventions

Lin William Cong, Sabrina T. Howell, May 20, 2020

The Chinese government has occasionally suspended IPOs, exogenously creating uncertainty about access to public markets for firms already approved to list. We show that suspension-induced delay reduces corporate innovation activity both during the delay and for years after listing.

The Dynamic Effects of Computerized VAT Invoices on Chinese Manufacturing Firms

Haichao Fan, Yu Liu, Nancy Qian, Jaya Wen, Aug 08, 2018

This investigation uses a balanced panel of large manufacturing firms to provide novel evidence on the dynamic effects of computerizing VAT invoices on tax revenues and firm behavior in China, 1998-2007. We find that computerization increases cumulative VAT revenues and increases the effective average tax rate. Furthermore, the evidence suggests that the effects of computerization change over time: tax revenue gains are likely to be smaller in the long run. Meanwhile, firms reduce output and input, and increase productivity monotonically over time.

Going Green in China: Firms’ Responses to Stricter Environmental Regulations

Haichao Fan, Joshua Graff Zivin, Zonglai Kou, Xueyue Liu, Huanhuan Wang, Apr 29, 2020

Evidence from China shows that firms respond to stricter enforcement of the emission reduction target by reducing their pollution. This effect is stronger for firms in industries with higher pollution intensity. Stricter environmental regulations also lead to sharp declines in firms’ profits, capital, and labor. A sequence of tests of the underlying mechanisms reveals...
