Are we underestimating the gains from globalization for the United States?
Over the last three decades, trade has more than tripled the variety of international goods available to U.S. consumers. Although an increased choice of goods clearly enhances consumer well-being, standard national measures of welfare and prices do not assign a value to variety growth. This analysis-the first effort to measure such gains-finds that the value to consumers of global variety growth in the 1972-2001 period was roughly $260 billion.

How much do bank shocks affect investment? Evidence from matched bank-firm loan data
We show that supply-side financial shocks have a large impact on firms' investment. We do this by developing a new methodology to separate firm-borrowing shocks from bank supply shocks using a vast sample of matched bank-firm lending data. We decompose loan movements in Japan for the period 1990 to 2010 into bank, firm, industry, and common shocks. The high degree of financial institution concentration means that individual banks are large relative to the size of the economy, which creates a role for granular shocks as in Gabaix (2011). As a result, bank supply shocks?that is, movements in ...

Do Bank Shocks Affect Aggregate Investment?
Traditionally, we have thought of the fates of specific banks as perhaps symptomatic of problems in the financial market but not as causal determinants of fluctuations in aggregate investment and other real economic activity. However, the high level of bank concentration in much of the OECD (Organisation for Economic Co-operation and Development) means that large amounts of lending are channeled through a small number of institutions that are no longer small even in comparison to the largest economies. Consequently, problems in a few large institutions could potentially have a large impact on ...

Global Supply Chains and U.S. Import Price Inflation
Inflation around the world increased dramatically with the reopening of economies following COVID-19. After reaching a peak of 11 percent in the second quarter of 2021, world trade prices dropped by more than five percentage points by the middle of 2023. U.S. import prices followed a similar pattern, albeit with a lower peak and a deeper trough. In a new study, we investigate what drove these price movements by using information on the prices charged for products shipped from fifty-two exporters to fifty-two importers, comprising more than twenty-five million trade flows. We uncover several ...

Supply- and demand-side factors in global banking
What is the role of supply and demand forces in determining movements in international banking flows? Answering this question is crucial for understanding the international transmission of financial shocks and formulating policy. This paper addresses the question by using the method developed in Amiti and Weinstein (forthcoming) to exactly decompose the growth in international bank credit into common shocks, idiosyncratic supply shocks, and idiosyncratic demand shocks for the 2000-16 period. A striking feature of the global banking flows data can be characterized by what we term the ?Anna ...

Did Trade Finance Contribute to the Global Trade Collapse?
The financial crisis of 2008-09 brought about one of the largest collapses in world trade since the end of World War II. Between the first quarter of 2008 and the first quarter of 2009, the value of real global GDP fell 4.6 percent while exports plummeted 17 percent, as can be seen in the chart below. The dramatic decline in world trade—a loss of $761 billion in nominal exports—came through two channels: decreased demand for imports and supply effects, most likely arising from financial constraints. In this post, we look at evidence that supply effects, including curtailed funding for ...

New China Tariffs Increase Costs to U.S. Households
Tariffs on $200 billion of U.S. imports from China subject to earlier 10 percent levies increased to 25 percent beginning May 10, 2019, after a breakdown in trade negotiations. In this post, we consider the cost of these higher tariffs to the typical U.S. household.

The Investment Cost of the U.S.-China Trade War
Starting in early 2018, the U.S. government imposed tariffs on over $300 billion of U.S. imports from China, increasing the average tariff rate from 2.7 percent to 17.5 percent. Much of the escalation in tariffs occurred in the second and third quarters of 2019. In response, the Chinese government retaliated, increasing the average tariff applied on U.S. exports from 5.7 percent to 20.4 percent. Our new study finds that the trade war reduced U.S. investment growth by 0.3 percentage points by the end of 2019, and is expected to shave another 1.6 percentage points off of investment growth by ...

Globalization and the gains from variety
Since the seminal work of Krugman, product variety has played a central role in models of trade and growth. In spite of the general use of love-of-variety models, there has been no systematic study of how the import of new varieties has contributed to national welfare gains in the United States. In this paper, we show that the unmeasured growth in product variety from U.S. imports has been an important source of gains from trade over the last three decades (1972-2001). Using extremely disaggregated data, we show that the number of imported product varieties has increased by a factor of four. ...

What Drives International Bank Credit?
A major question facing policymakers is how to deal with slumps in bank credit. The policy prescriptions are very different depending on whether the decline is a result of global forces, domestic demand, or supply problems in a particular banking system. We present findings from new research that exactly decompose the growth in banks? aggregate foreign credit into these three factors. Using global banking data for the period 2000-16, we uncover some striking patterns in bilateral credit relationships between consolidated banking systems and borrowers in more than 200 countries. The most ...
