What Drives US Import Price Inflation?

May 2024

AEA Papers and Proceedings

Inflation has risen sharply in many countries since the COVID-19 outbreak, and economists have debated the underlying causes. In this paper, we examine the drivers of the global import price inflation, which peaked at approximately 11 percent a year. We find that a common global component closely tracks movements in aggregate US import prices until late 2022. Afterward, idiosyncratic US demand shocks started to dominate.

Review of Economic Studies

Many studies have documented that the sales concentration of U.S. producers has risen in recent decades. In this article, we show that this increase was accompanied by more entry and growth of foreign competitors. Using confidential census data covering the universe of all firm sales in the U.S. manufacturing sector, we find that rising import competition increased concentration among U.S. firms by reallocating sales from smaller to larger U.S. firms and by causing firm exit. However, this increase in production concentration was counteracted by the expansion of foreign firms, which reduced domestic firms’ share of the U.S. market inclusive of foreign firms’ sales. We find that once the sales of foreign exporters are taken into account, U.S. market concentration in manufacturing was stable between 1992 and 2012.





Dominant Currencies: How Firms Choose Currency Invoicing and Why it Matters

We analyze how firms choose the currency of invoicing and the implications of this choice for exchange rate pass-through into export prices and quantities. Using a new dataset for Belgian firms, we find currency invoicing to be an active firm-level decision, shaped by the firm’s size, exposure to imported inputs, and the currency choices of its competitors. Our results show that the firm’s currency choice, in turn, has a direct causal impact on the exchange rate pass-through into prices and quantities. Moreover, the differential price response of similar firms that invoice in different currencies is large, persists beyond a one-year horizon, and gradually wanes in the long run. This results in allocative expenditure-switching effects on export quantities, which build up over time, suggesting a role for quantity adjustment frictions in addition to price stickiness. Our findings shed light on the mechanisms that make or break a dominant currency and the consequences it has for the international transmission of shocks.

AEA Papers and Proceedings

Using another year of data including significant escalations in the trade war, we find that the costs of the US tariffs continue to be almost entirely borne by US firms and consumers. We show that the response of import values to the tariffs increases in absolute magnitude over time, consistent with the idea that it takes time for firms to reorganize supply chains. We find heterogeneity in the responses of some sectors, such as steel, where tariffs have caused foreign exporters to drop their prices substantially, enabling them to export relatively more than in sectors where tariff pass-through was complete.

... Regarding the relationship between FDI and industrial agglomeration, Amiti and Javorcik (29) believed that in case of improved freedom of trade in a country, upstream and downstream enterprises often go with the stream and swarm into this country (29). The FDI promotes the agglomeration of local industries by improving the technological innovation capacity of the host country and realizing technological spillover of such capacity among enterprises (30). ...

... Today the O & G is still one of the most lucrative industries on earth, making up 3.8% of the world's economy [8]. In the USA, the bureau of statistics revealed that 118 thousand people work for the O & G industry and generated a revenue of $333 billion, which is a per capita income of $2,822,034 [9]. Therefore, the O & G industry has a lot of capital to delay the advent of other modes of transportation that do not use their products. ...

... Hence, they cannot distinguish a sharp rise and fall in goods inflation from a more muted but more persistent variation in services inflation. Amiti et al. (2023), Comin et al. (2023), andFerrante et al. (2023) set-up a multi-sector New Keynesian model and explain the disparity between goods inflation and services inflation. In Amiti et al. (2023) and Comin et al. (2023), supply disruptions play an important role in creating a rapid increase in goods inflation while Ferrante et al. (2023) emphasizes the sectoral demand reallocation during the COVID-19 period (from services to goods) as a main factor of goods inflation. ...

... There is broad consensus that developing an open economy is a key factor to economic growth ( Acs & Virgill, 2009;Giles & Williams, 2000;Gundlach, 1997). In particular, a country's open economy facilitates innovation and productivity growth through different mechanisms, such as knowledge spillovers from other trade partners (Amiti et al., 2023;Huang & Zhang, 2020) or allowing underdeveloped countries to accelerate their innovation drive by imitating leading countries (Minniti & L evesque, 2010). Moreover, the openness or connectivity of a regional economy is an important factor that impacts the building of pipelines through which external knowledge is channelled into the region, which can aid in the development of innovation capabilities (W. ...

... This process can be done in one firm, or in different firms within or outside of a country. GVC emphasizes how export competitiveness depends on the sourcing of important inputs, and, thus participation of GVC has impact on GDP as well as on investment and productivity (Amiti and Wei 2009;Liu 2014;Kummritz 2016;Ignatenko, Raei, and Mircheva 2019). Theoretically, GVC participation could encourage domestic investment. ...

... Specifically, the discussions surrounding the choice of currency have gained prominence in international finance (Adler et al. 2020;Amiti, Itskhoki, and Konings 2022;. These studies reveal that as a few currencies, such as the US dollar, dominate international trade in terms of pricing, invoicing, and settlement, this can change the traditional trade flows responding to a country's exchange rate movements. ...

... 6 The agreement between Canada, Mexico and the United States in force since July 2020 is called the United States-Mexico-Canada Agreement (USMCA) in the USA, in Canada is officially known as the Canada-United States-Mexico Agreement (CUSMA) in English and the Accord Canada-États-Unis-Mexique (ACEUM) in French, and in Mexico is Tratado entre México, Estados Unidos y Canadá (T-MEC). 7 Estimates of the tariff below which it will not be worth claiming preferential treatment range from 4% (Francois et al., 2005) to 5% (Amiti and Romalis, 2006). Based on analysis of 94 countries from years around 2010, Hayakawa et al. (2018) found that exporters to the ASEAN countries, Australia, China, Japan, Korea, and New Zealand made very little use of preferential tariffs. ...

As in previous studies analyzing the effects of offshoring/reshoring strategies on employment (Agnese, 2012;Amiti & Wei, 2005Fuster et al., 2019;Michel & Rycx, 2012;Winkler, 2010;Wrigth, 2014 for the case of offshoring, and Fuster et al., 2020 for the case of reshoring), a log-linear labor demand function is derived from a homogeneous production function with constant returns to scale (CRS) (Hamermesh, 1993). In addition, the dependence of imported service inputs on total output is included as an explanatory variable. ...

... Moreover, despite the proven role of services in production (Arndt and Kierzkowski 2001;Fisher 1939) and growth (Baer and Samuelson 1981;Baumol 1967;Lee and McKibbin 2018;Romão 2020), there is less focus on the role of trade services in export product diversification. Yet, some theoretical and empirical evidences show the importance of commercial services in manufacturing production dynamism (Amiti and Wei 2005;Arnold et al. 2008;Beverelli et al. 2017;Chand and Sen 2002;UNCTAD 2022;Vogel 2022). The focus has been more relevant on services imports as inputs into production processes, but the main question here is to question the role of commercial services exports in the export product diversification. ...
