Understanding Trade Fragmentation
A large empirical literature, including Gopinath et al. (2025), finds that geopolitical distance has become an increasingly important determinant of bilateral trade flows. This work has fueled debate about the consequences of fragmentation and the extent to which global value chains are being reshaped.

Effects of Supply Chain Bottlenecks on Prices using Textual Analysis
After collapsing in the second half of 2020, global demand for goods, as reflected in global trade, has been exceptionally strong and now well exceeds pre-pandemic levels. The sharp bounceback reflects several factors, including an unprecedented amount of global stimulus and the drawdown of excess savings (especially for high-income households).

Fiscal policy and excess inflation during Covid-19: a cross-country view
The recent surge in inflation in many countries around the world and the fiscal stimulus provided in the face of the COVID-19 pandemic has renewed interest in analyzing the potential role of large fiscal spending as a driver of price increases. In this note, we examine how fiscal support impacted the balance between supply and demand across countries during the COVID-19 crisis.

Real GDP and Productivity Measurement: What Do Macro Data Capture?
Since the publication of their 2021 "Blue Book", the UK's Office for National Statistics started to measure real GDP in the national accounts using double deflation. This methodological update follows the premise that "double deflation is internationally accepted as the best approach to producing volume estimates of industry Gross Value Added".

The Sectoral Evolution of China’s Trade
Since 2018, Chinese officials have been emphasizing the need for China to achieve greater self-reliance. As discussed in de Soyres and Moore (2024), China has reduced its reliance on imported inputs, while simultaneously becoming more dependent on foreign demand to absorb its manufactured goods. In this Note, we look at the evolution of the sectoral composition of China's exports and imports and investigate its similarity with the sectoral composition of the trade baskets of advanced economies (AEs). First, using a gravity model, we show that bilateral trade flows are significantly influenced ...

Demand-Supply imbalance during the Covid-19 pandemic: The role of fiscal policy
To mitigate the health and economic fallout from the COVID-19 pandemic, governments worldwide engaged in massive fiscal support programs. We show that generous fiscal support contributed to an increase in the demand for consumption goods during the pandemic, but industrial production did not adjust quickly enough to meet the sharp increase in demand. This imbalance between supply and demand across countries led to high inflation. Our findings suggest a sizable role for fiscal policy in affecting price stability.

What is Measured in National Accounts?
Most statistical agencies construct sectoral real GDP using double deflation and base period prices. When the base period price used for intermediate inputs is not equal to their marginal revenue product, such as when firms apply a markup, real GDP fluctuations become mechanically linked to variations in intermediate inputs. This is because these inputs generate profits that are incorporated into real value added. Taking this channel into account, we demonstrate that real GDP reported in national accounts substantially diverges from a theory-consistent "physical" value added. This, in turn, ...

Demand-Supply Imbalance during the COVID-19 Pandemic: The Role of Fiscal Policy
To mitigate the health and economic fallout from the COVID-19 pandemic, governments worldwide engaged in massive fiscal support programs. We show that generous fiscal support is associated with an increase in the demand for consumption goods during the pandemic, but industrial production did not adjust quickly enough to meet the sharp increase in demand. This imbalance between supply and demand across countries contributed to high inflation. Our findings suggest a sizable role for fiscal policy in affecting price stability, above and beyond what a monetary authority can do.

Partner Similarity and The Sectoral Evolution of China's Trade
We study how the sectoral composition of exports and imports shapes bilateral trade flows. Building on earlier similarity indices, we introduce the Partner Similarity Index (PSI), which measures sectoral alignment between a country’s export structure and its partner’s import demand. Embedded in a gravity framework, PSI is a strong predictor of bilateral trade flows after accounting for standard gravity determinants, trade policy variables, and high-dimensional fixed effects. Applied to China and advanced economies, the index reveals growing asymmetries: China’s export basket is ...
