Multinational Production and Innovation in Tandem (Job Market Paper)

Awarded FREIT-EIIT Best Graduate Student Paper Prize, 2023

Multinational firms colocate production and innovation by offshoring them to the same host country or region. In this paper, I examine the determinants of multinational firms’ production and innovation locations. I find complementarities between production and innovation within host countries and regions, exploiting plausibly exogenous variation in tariffs. To evaluate manufacturing reshoring policies, I develop a quantifiable multicountry offshoring location choice model. I allow for rich colocation benefits and cross-country interdependence and prove supermodularity of the model to solve this otherwise NP-hard problem. I find the effects of manufacturing reshoring policies are nonlinear, contingent upon firm heterogeneity, and they accumulate dynamically.



Stand Out from the Millions: Market Congestion and Information Friction on Global  E-Commerce Platforms

Joint with Jie Bai, Maggie Chen, Xiaosheng Mu, and Daniel Yi Xu, Under submission

We investigate how market congestion and information friction affect firm dynamics and market efficiency in global e-commerce. Observational data and self-collected quality measures from AliExpress suggest significant demand frictions and potential misallocation in the online market. A randomized experiment that offers new exporters exogenous demand and information shocks demonstrates the limited ability of existing platform mechanisms to help small sellers overcome the demand frictions. We show theoretically and quantitatively that having a large number of market participants undermines the functioning of existing online mechanisms and hinders the discovery of high-quality sellers. Policy counterfactuals highlight that blanket-wide onboarding initiatives can aggravate market congestion, slow down the resolution of the information problem, and result in market misallocation.

Patent Signaling

Joint with Deepak Hegde and Boyan Jovanovic

We develop a model of strategic disclosure in which patenting inventors possess private information about their invention’s quality. We show that under certain conditions, high quality inventors signal their private information by disclosing their patents sooner. We test the model’s predictions by analyzing inventors’ disclosure choices after the American Inventors’ Protection Act of 1999, which allowed inventors to accelerate the disclosure of their patent applications. The empirical results are consistent with the model’s predictions and suggest large industry-level variation in inventors’ disclosure strategies and competitors’ learning from disclosures.

Do Industrial Policies Lead to Excess Capacity? Empirical Evidence from China

Joint with Zonglai Kou and Xueyue Liu, Fudan Journal (Social Sciences Edition), 59(5), 2017: 148-161. 

Industrial policies on capital investment in China come in two types—those that incentivize firms to purchase more equipment, and those that discourage investment by restricting firms' equipment choices or even mandating divestment of existing equipment. The encouraging policies effectively induce more investment and lead to rising excess capacity, especially in state-owned firms. However, the restrictive policies have little effect on reducing excess capacity.
