How much has the US-China tariff war impacted economic outcomes in China? We address this question using high-frequency night lights data, together with measures of the trade exposure of fine grid locations constructed from Chinese firms' geo-coordinates. Exploiting within-grid variation over...

We survey the empirical literature in economics on the impact of media technologies on social capital. Motivated by a simple model of information and collective action, we cover a range of different outcomes related to social capital, from social and political participation to interpersonal...

We study the relationship between the spread of social media platforms and the communication and responsiveness of politicians towards voters, in the context of the expansion of Facebook in Brazil. We use self-collected data on the universe of Facebook activities by federal legislators and the...

We study how adverse economic shocks influence political outcomes in authoritarian regimes in strong states, by examining the 2013-2015 export slowdown in China. We exploit detailed customs data and the variation they reveal about Chinese prefectures' underlying exposure to the global trade...

This paper surveys the recent body of work in economics on the importance of global value chains (GVCs) in shaping international trade flows and multinational activity. On the empirical front, we begin reviewing several variants of the "macro approach" to measuring the relevance of global...

Global supply chains have come under unprecedented stress as a result of US-China trade tensions, the Covid-19 pandemic, and geopolitical shocks. We document shifts in the pattern of US participation in global value chains over the last four decades, in terms of partner countries, products, and...

We investigate the role of evidence-based information in shaping individuals' preferences for trade policies through a series of survey experiments that contain randomized information treatments. Each treatment provides a concise statement of economics research findings on how openness to trade...

In the two decades straddling China's WTO accession, the China Shock, i.e. the rapid trade integration of China in the early 2000's, has had a profound economic impact across U.S. regions. It is now both an internationally litigated issue and the casus belli for a global trade war. Were its...

Has the expansion in exports affected pollution and health outcomes across different prefectures in China in the two decades between 1990 and 2010? We exploit variation in the initial industrial composition to gauge the effect of export expansion due to the decline in tariffs faced by Chinese...

Buenos Aires and Chicago grew during the nineteenth century for remarkably similar reasons. Both cities were conduits for moving meat and grain from fertile hinterlands to eastern markets. However, despite their initial similarities, Chicago was vastly more prosperous for most of the 20th...
