To what extent do political relations between countries affect their economic exchange? Using evidence of China’s relations with other major powers during the period of 1990 to 2013, Yingxin Du, Jiandong Ju, Carlos D. Ramirez, and Xi Yao point out the time-aggregation bias in the existing empirical research and provide insights on the relationship between political shocks and trade.
Despite reforms to the hukou household registration system and the very large rural-urban migration experienced in China, rural households are still experiencing a risk of losing their land allocation if they migrate. We argue that this risk leads to an inefficient rental market with low rents and is an impediment to migration, with consequent over-employment in agriculture and low productivity.
Using a unique Chinese data set capturing the trading behavior of particularly aggressive investors, we provide new evidence that is consistent with the presence of informational advantages. Critically, an advantage of our data is that we can also directly identify several plausible channels through which such an informational advantage could arise. Specifically, return predictability around key value-relevant events is most pronounced in the presence of aggressive traders who share the same geographic location as the firms in which they trade.
We study the effects of compliance with the value-added tax (VAT) by exploiting the reform that replaced business tax (BT) with VAT in China beginning in 2012. We find that replacing the BT with VAT significantly increases the reported sales and costs for treated firms, and the impact is much stronger for business-to-business (B2B) transactions than for business-to-consumer (B2C) transactions. Buyers in B2B transactions...
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.
