A salient feature of globalization in recent decades is the emergence of "global supply chains" in which different countries specialize in different stages of a sequential production process. In Arnaud Costinot, Jonathan Vogel and Su Wang (2011), CVW hereafter, we have developed a simple theory...

Recent advances in information technology (IT) have enabled firms in many industries to give middle managers new access to timely production data. Process monitoring' technologies give distant managers a window to production which can both lower their cost of monitoring subordinates and provide...

Using monthly data on temporary trade barriers (TTBs), we estimate the dynamic employment effects of protectionism through vertical production linkages. First, exploiting procedural details of TTBs and high-frequency data, we identify movements in protectionism exogenous to economic...

Although fake online customer reviews have become prevalent on platforms such as Amazon, Google, and Facebook, little is known about how these reviews influence consumer behavior. This paper provides the first experimental estimates of the effects of fake reviews on individual demand and...

Coal heating in residential homes is an important source of indoor air pollution, leading to detrimental health effects. We conduct a randomized field experiment in northern China using three types of SMS campaigns targeting three potential biases that may hinder the adoption of electric...
