We link U.S. job records with both firm-level business register and customs records to construct a novel set of summary statistics and descriptive regressions that highlight the central role played by the small set of multinational firms (denoted RP XM firms) who engage in both importing and exporting with related parties in translating international trade shocks to shifts in labor demand. We find that RP XM firms 1) dominate trade volumes; 2) account for very disproportionate shares of national employment and payroll; 3) employ greater shares of workers in higher pay deciles; 4) disproportionately poach other firms' high paid workers; 5) offer higher raises to their existing workers. These hiring and pay patterns generally exist even among new RP XM firms, but strengthen with RP XM tenure, and continue to hold, albeit at smaller magnitudes, after conditioning on standard proxies for firm and worker productivity. Taken together, these findings reveal that RP XM status is a reliable proxy for the kind of firm that drives the initial labor market impacts of trade shocks, and that high paid workers are likely to be most directly exposed to such shocks.

U.S. Worker Mobility Across Establishments within Firms: Scope, Prevalence, and Effects on Worker Earnings
May 2024
Working Paper Number:
CES-24-24
Multi-establishment firms account for around 60% of U.S. workers' primary employers, providing ample opportunity for workers to change their work location without changing their employer. Using U.S. matched employer-employee data, this paper analyzes workers' access to and use of such between-establishment job transitions, and estimates the effect on workers' earnings growth of greater access, as measured by proximity of employment at other within-firm establishments. While establishment transitions are not perfectly observed, we estimate that within-firm establishment transitions account for 7.8% percent of all job transitions and 18.2% of transitions originating from the largest firms. Using variation in worker's establishment locations within their firms' establishment network, we show that having a greater share of the firm's jobs in nearby establishments generates meaningful increases in workers' earnings: a worker at the 90th percentile of earnings gains from more proximate within-firm job opportunities can expect to enjoy 2% higher average earnings over the following five years than a worker at the 10th percentile with the same baseline earnings.

Pay, Productivity and Management
September 2021
Working Paper Number:
CES-21-31
Using confidential Census matched employer-employee earnings data we find that employees at more productive firms, and firms with more structured management practices, have substantially higher pay, both on average and across every percentile of the pay distribution. This pay-performance relationship is particularly strong amongst higher paid employees, with a doubling of firm productivity associated with 11% more pay for the highest-paid employee (likely the CEO) compared to 4.7% for the median worker. This pay-performance link holds in public and private firms, although it is almost twice as strong in public firms for the highest-paid employees. Top pay volatility is also strongly related to productivity and structured management, suggesting this performance-pay relationship arises from more aggressive monitoring and incentive practices for top earners.

Importers, Exporters, and Multinationals: A Portrait of Firms in the U.S. that Trade Goods
October 2005
Working Paper Number:
CES-05-20
This paper provides an integrated view of globally engaged U.S. firms by exploring a newly developed dataset that links U.S. international trade transactions to longitudinal data on U.S. enterprises. These data permit examination of a number of new dimensions of firm activity, including how many products firms trade, how many countries firms trade with, the characteristics of those countries, the concentration of trade across firms, whether firms transact at arms length or with related parties, and whether firms import as well as export. Firms that trade goods play an important role in the U.S., employing more than a third of the U.S. workforce. We find that the most globally engaged U.S. firms, i.e. those that both export to and import from related parties, dominate U.S. trade flows and employment at trading firms. We also find that firms that begin trading between 1993 and 2000 experience especially rapid employment growth and are a major force in overall job creation.

Decomposing Aggregate Trade Flows: New Evidence from U.S. Traders
September 2012
Working Paper Number:
CES-12-17
Using firm-level data on export transactions, we uncover a rich set of results about the extensive margins of exporting and exporter responses during periods of global downturns. We perform our analysis with respect to firm size, age, ownership status, and sector to emphasize the role of firm heterogeneity. We uncover a larger role for firm entry and exit in changes in annual export flows of single-unit, smaller, and younger firms. Young, small firms perform best during both periods of crises as well as non-crises periods. We also decompose the margins of U.S. imports at the U.S. importer, foreign supplier, and U.S. importer-foreign supplier pair levels. While export flows are closely correlated with global business cycles, import flows more closely approximate U.S. economic cycles. Additionally, both pair and foreign supplier flows are far more volatile than U.S. import flows, that is, U.S. importer-foreign supplier matches experience more churning on average than do either U.S. importers or foreign suppliers.

IMPORTING, EXPORTING AND FIRM-LEVEL EMPLOYMENT VOLATILITY
June 2013
Working Paper Number:
CES-13-31
In this paper, we use detailed trade and transactions data for the U.S. manufacturing sector to empirically analyze the direction and magnitude of the association between firm-level exposure to trade and the volatility of employment growth. We find that, relative to purely domestic firms, firms that only export and firms that both export and import are less volatile, whereas firms that only import are more volatile. The positive relationship between importing and volatility is driven mainly by firms that switch in and out of importing. We also document a significant degree of heterogeneity across trading firms in terms of the duration of time and intensity with which firms trade, the number and type of products they trade and the number and characteristics of their trading partners. We find these factors to play an important role in explaining the differential impact of trading on employment volatility experienced by these firms.

Import Competition from and Offshoring to Low-Income Countries: Implications for Employment and Wages at U.S. Domestic Manufacturers
January 2017
Working Paper Number:
CES-17-31
Using confidential linked firm-level trade transactions and census data between 1997 and 2012, we provide new evidence on how American firms without foreign affiliates adjust employment and wages as they adapt to import competition from low-income countries. We provide stylized facts on the input sourcing strategies of these domestic firms, contrasting them with multinationals operating in the same industry. We then investigate how changes in firm input purchases from low-income countries as well as domestic market import penetration from these sources are correlated with changes in employment and wages at surviving domestic firms. Greater offshoring by domestic firms from low-income countries correlates with larger declines in manufacturing employment and in the average production workers' wage. Given the negative association, however, the estimated magnitudes are small, even for a narrow measure of offshoring that includes only intermediate goods. Import penetration of U.S. markets from these sources is associated with relatively larger changes in employment for arm's length importing firms, but has no significant correlation with employment changes at firms that do not trade. Given differences in the degree of both offshoring and import penetration, we find substantial variation across industries in the magnitude of changes associated with low-income country imports.

Earnings Inequality and Coordination Costs: Evidence from U.S. Law Firms
September 2009
Working Paper Number:
CES-09-24
Earnings inequality has increased substantially since the 1970s. Using evidence from confidential Census data on U.S. law offices on lawyers' organization and earnings, we study the extent to which the mechanism suggested by Lucas (1978) and Rosen (1982), a scale of operations effect linking spans of control and earnings inequality, is responsible for increases in inequality. We first show that earnings inequality among lawyers increased substantially between 1977 and 1992, and that the distribution of partner-associate ratios across offices changed in ways consistent with the hypothesis that coordination costs fell during this period. We then propose a 'hierarchical production function' in which output is the product of skill and time and estimate its parameters, applying insights from the equilibrium assignment literature. We find that coordination costs fell broadly and steadily during this period, so that hiring one's first associate leveraged a partner's skill by about 30% more in 1992 than 1977. We find also that changes in lawyers' hierarchical organization account for about 2/3 of the increase in earnings inequality among lawyers in the upper tail, but a much smaller share of the increase in inequality between lawyers in the upper tail and other lawyers. These findings indicate that new organizational efficiencies potentially explain increases in inequality, especially among individuals toward the top of the earnings distribution.

A Long View of Employment Growth and Firm Dynamics in the United States: Importers vs. Exporters vs. Non-Traders
December 2021
Working Paper Number:
CES-21-38
The first experimental product from the U.S. Census Bureau's Business Dynamics Statistics (BDS) program -- BDS-Goods Traders -- provides annual, public-use measures of business dynamics by four mutually exclusive goods-trading classifications: exporter only, importer only, exporter and importer, and non-trader. The BDS-Goods Traders offers a comprehensive view of employment growth at firms associated with goods trading activities in the United States from 1992-2019. We highlight three patterns. First, employment is skewed towards goods traders in several ways. Only 6% of all U.S. firms are goods traders but they account for half of total employment. Moreover, 80% of large firms and 70% of older firms are goods traders. Second, exporter-importer firms represent 70% of manufacturing employment and over half of employment in services-producing industries (management, retail, transportation, utilities, and wholesale). Third, goods-traders exhibit higher net job creation rates than non-traders controlling for firm size, age, and sector. Goods traders contribution to total job creation grows over time, rising to more than half after 2008.

The China Shock Revisited: Job Reallocation and Industry Switching in U.S. Labor Markets
October 2024
Working Paper Number:
CES-24-65
Using confidential administrative data from the U.S. Census Bureau we revisit how the rise in Chinese import penetration has reshaped U.S. local labor markets. Local labor markets more exposed to the China shock experienced larger reallocation from manufacturing to services jobs. Most of this reallocation occurred within firms that simultaneously contracted manufacturing operations while expanding employment in services. Notably, about 40% of the manufacturing job loss effect is due to continuing establishments switching their primary activity from manufacturing to trade-related services such as research, management, and wholesale. The effects of Chinese import penetration vary by local labor market characteristics. In areas with high human capital, including much of the West Coast and large cities, job reallocation from manufacturing to services has been substantial. In areas with low human capital and a high initial manufacturing share, including much of the Midwest and the South, we find limited job reallocation. We estimate this differential response to the China shock accounts for half of the 1997-2007 job growth gap between these regions.

Pay, Employment, and Dynamics of Young Firms
July 2019
Working Paper Number:
CES-19-23
Why do young firms pay less? Using confidential microdata from the US Census Bureau, we find lower earnings among workers at young firms. However, we argue that such measurement is likely subject to worker and firm selection. Exploiting the two-sided panel nature of the data to control for relevant dimensions of worker and firm heterogeneity, we uncover a positive and significant young-firm pay premium. Furthermore, we show that worker selection at firm birth is related to future firm dynamics, including survival and growth. We tie our empirical findings to a simple model of pay, employment, and dynamics of young firms.
