The Impact of Exporting on the Stability of U.S. Manufacturing Industries v 

Executive Summary 

Exporting provides opportunities to expand the sales of U.S. manufacturing industries, 

resulting in greater revenues for U.S. companies and higher employment for U.S. workers. 

However, investors and workers are concerned about risk as well as expected return, and risk 

depends on the volatility of economic outcomes. In the case of exports, it is worth asking 

whether the added risks and unpredictability associated with exporting outweigh the increase in 

expected revenues. 

In theory, exporting could increase the volatility of the total shipments of U.S. 

manufacturers by increasing cost competition and by exposing the manufacturers to other types 

of uncertainty, including exchange rate volatility and fluctuations in shipping costs. On the other 

hand, exporting could reduce the volatility of their total shipments by diversifying shocks to 

product demand. 

In this paper, we investigate the recent link between exporting and the economic stability 

of the U.S. manufacturing sector. We compare the volatility of the domestic shipments of U.S. 

companies and industries to the volatility of their total, worldwide shipments. 

First, we analyze the 2000-2009 revenues reported in the public financial statements of 

two U.S. companies with substantial non-U.S. sales, the Xerox Corporation and the Dow 

Chemical Company. Both case studies indicate that the companies’ non-U.S. revenues reduce 

the volatility of their total, worldwide revenues. 

Second, we analyze industry-level shipments data for the U.S. manufacturing sector from 

the Annual Survey of Manufactures and the Economic Census for the period 2000-2008. The 

industry-level data indicate that exporting reduces the volatility of total shipments for a 

significant majority of the U.S. manufacturing industries. In general, industries with higher 

export shares experienced larger reductions in the volatility of their total shipments.

The Impact of Exporting on the Stability of U.S. Manufacturing Industries 1 

1. Introduction 

Exporting provides opportunities to expand the sales of U.S. manufacturing industries, 

resulting in greater revenues for U.S. companies and higher employment for U.S. workers. 

However, investors and workers are concerned about risk as well as expected return, and risk 

depends on the volatility of economic outcomes. In the case of exports, it is worth asking 

whether the added risks and unpredictability associated with exporting outweigh the increase in 

expected revenues. 

In theory, exporting could increase the volatility of the total shipments of U.S. 

manufacturers by increasing cost competition and by exposing the manufacturers to other types 

of uncertainty, including exchange rate volatility and fluctuations in shipping costs. On the other 

hand, exporting could reduce the volatility of the total shipments of U.S. manufacturers by 

diversifying shocks to product demand. If the second effect dominates, and the volatility of the 

total shipments of U.S. manufacturers are less than the volatility of their U.S. shipments, then 

exporting reduces the volatility of the manufacturers’ revenue streams. Reducing the volatility 

of revenues has clear economic benefits. It is valuable to companies and workers that prefer 

income stability. In addition, reduced volatility can encourage investment in new technologies, 

physical capital, and human capital.1

 

 In this paper, we investigate the recent empirical link between exporting and the 

economic stability of U.S. manufacturing industries. To measure the volatility of the shipments 

of U.S. manufacturers, we calculate the ratio of the standard deviation of the unpredictable 

component of shipments to the most recent value of shipments. We call this ratio the normalized 

volatility of shipments. Since the standard deviation and the most recent value of shipments are 

measured in the same units, the units cancel from the ratio. This conversion to a percentage, or 

normalization, facilitates comparison of the volatility measures among companies and industries 

that vary significantly in size. 

We compare the volatility of the domestic shipments of U.S. companies and industries to 

the volatility of their total, worldwide shipments. First, we examine the 2000-2009 revenues 

reported in the public financial statements of two U.S. companies with substantial non-U.S.

sales, the Xerox Corporation and the Dow Chemical Company.2 Then we build on these 

company case studies by analyzing industry-level shipments data for the U.S. manufacturing 

sector from the Annual Survey of Manufactures (ASM) and the Economic Census for the period 

2000-2008. 

2. Company Case Study: The Xerox Corporation 

 The Xerox Corporation (Xerox) is a global document management company that was 

founded in 1906 and is currently headquartered in Norwalk, Connecticut. 3 The company 

employs approximately 130,000 people worldwide. It serves non-U.S. markets through a 

combination of U.S. exports and foreign production, including joint ventures. The company’s 

product offerings include copiers, fax machines, and printers, as well as related services and 

supplies. The company identifies the reputation of its brands and its innovative technologies as 

the keys to its international success. 

 Xerox publicly reports its annual revenues for three geographic areas: the United States, 

Europe, and Other Areas. It is important to note that the company’s non-U.S. revenues are not 

exclusively exports from the United States. They include sales of goods and services produced 

by the company’s foreign affiliates.4

 The company’s exports from the United States are not 

separately quantified in the company’s Annual Reports. This is a limitation on the usefulness of 

publicly available company data for analyzing the link between exports and the volatility of 

revenues. (However, this limitation does not apply to the industry-level analysis that we report 

below.) 

 Table 1 reports the company’s 2000-2009 revenues by geographic area. In 2009, U.S. 

revenues accounted for 53.7% of the total revenues of Xerox.

 We analyzed these specific companies because they publicly report their revenues by geographic area, separating 

U.S. revenues from non-U.S. revenues. This report is not intended to praise or criticize these two companies. It is 

simply restating information that is published in the companies’ public annual reports in terms of our analytical 

framework.

 The following company profile is based on the 2009 Annual Report of the Xerox Corporation.

 Likewise, the reported U.S. sales are not necessarily limited to the company’s U.S. production. They may include 

U.S. imports from the company’s foreign affiliates.

Source: Annual Reports of the Xerox Corporation. 

Between 2000 and 2009, the company’s annual U.S. revenues ranged from $8.06 billion to 

$13.10 billion in constant 2008 dollars.5 Its annual total revenues ranged from $15.00 billion to 

$22.95 billion over this period. The normalized volatility of the company’s total revenues 

(7.52%) was smaller than the normalized volatility of its U.S. revenues (8.53%), so the 

company’s non-U.S. revenues reduced the normalized volatility of its total revenues.6 

3. Company Case Study: the Dow Chemical Company 

 The Dow Chemical Company (Dow) is one of the largest chemical producers in the 

world.7

 It was founded in 1897 and is headquartered in Midland, Michigan. Dow manufactures 

and sells chemicals, plastic materials, agricultural products and services, advanced materials and 

other specialized products and services. The company employs approximately 52,000 people 

worldwide. The company’s success in technological innovation is fueled by annual R&D

 Throughout this paper, we report all dollar values in 2008 constant dollars.

 To measure volatility, we removed the industry-specific mean and linear trend from the shipments data. We 

discuss this adjustment to the data in the Technical Appendix. The standard deviation is the square root of the 

average of the squared differences between the variable and its predicted value for each industry and each year. 

Since there are trends in the data, the predicted values change over time.

expenditures in excess of $1 billion. Dow identifies the geographic balance of its sales as a key 

to its success. 

 Dow reports its annual revenues for three geographic areas: the United States, Europe, 

and the Rest of World. Again, it is important to note that the company’s non-U.S. revenues are 

not exclusively exports from the United States. Table 2 reports the company’s 2000-2009 

revenues by geographic area. 

Table 2: Annual Revenues of the Dow Chemical Company by Geographic Segment 

Source: Annual Reports of the Dow Chemical Company. 

In 2009, U.S. revenues accounted for 31.5% of the total revenues of Dow. Between 2000 and 

2009, the company’s annual U.S. revenues ranged from $13.26 billion to $19.09 billion in 

constant 2008 dollars. Its annual total revenues ranged from $32.51 billion to $57.36 billion. 

The normalized volatility of the company’s total revenues (11.93%) was smaller than the 

normalized volatility of its U.S. revenues (14.55%), so the company’s non-U.S. revenues 

reduced the volatility of its total revenues.

4. Analysis of 85 Manufacturing Industries in the U.S. 

Manufacturing Sector 

 While the two company case studies provide a measure of the reduction in the normalized 

volatility of total revenues that results from adding non-U.S. sales to U.S. sales, they do not 

specifically quantify the contribution of exports from the United States. However, using 

industry-level data, we can focus the comparisons of normalized volatilities on the shipments of 

U.S. production to the United States and foreign markets. The industry-level analysis also has 

the advantage that it covers the entire U.S. manufacturing sector, and so it significantly expands 

the breadth of the analysis. 

 We analyze publicly available four-digit NAICS industry data on the value of shipments 

from the ASM for 2000-2001, 2003-2006, and 2008 and from the Economic Census for 2002 

and 2007. At this level of disaggregation, there are 85 industries in the U.S. manufacturing 

sector. The ASM is based on a subset of the population of establishments in the Economic 

Census. It includes approximately 55,000 manufacturing establishments, with 10,000 large 

establishments selected with certainty and another 45,000 other establishments selected with 

probability proportional to establishment size. To be included in the ASM, a manufacturing 

establishment must have one or more paid employees or leased employees engaged in activities 

that are classified in NAICS industries 31 through 33. 

In order to calculate the domestic shipments of the U.S. industries, we supplement the 

ASM data with statistics on the free alongside ship value of U.S. domestic exports from the U.S. 

ITC’s Trade Dataweb.8

 We calculate the U.S. shipments of each industry in each year as the 

difference between its total value of shipments and its domestic exports. Across the 85 

industries, the ratio of exports to total shipments in 2008 ranged from 0.6% to 71.7%, with a 

simple average of 19.1%. 

Using these data, we estimate the contribution of exporting to the normalized volatility of 

the total value of shipments of the U.S. manufacturing industries. Before we report the volatility

 U.S. domestic exports are produced in the United States. By definition, they include goods from U.S. Foreign 

Trade Zones that have been enhanced in value. They do not include re-exports. The U.S. International Trade 

Commission defines the free alongside ship value as “the value of exports at the U.S. port, based on the transaction 

price, including inland freight, insurance, and other charges. The value excludes the cost of loading the merchandise 

aboard the carrier and also excludes any further costs.”

comparisons for all 85 industries, we will go through a detailed example for a single industry, the 

Medical Equipment and Supplies Manufacturing industry (NAICS 3391). In 2008, this industry 

had U.S. shipments of $64.09 billion, and total shipments of $84.03 billion (Table 3).

Dataweb. 

The difference between these two numbers is the industry’s exports. Between 2000 and 

2008, the standard deviation of unpredictable component of the industry’s U.S. shipments was 

$1.78 billion, and the standard deviation of the unpredictable component of its total shipments 

was $1.84 billion. Although the standard deviation was greater for the U.S. industry’s total 

shipments than for its U.S. shipments, the percentage increase in the standard deviation from

expanding the market (3.37%, or 1.84/1.78-1) was smaller than the percentage increase in the 

2008 value of shipments (43.12%, or 69.17/48.33-1). It follows that the normalized volatility of 

the industry’s total shipments (2.1%) is less than the normalized volatility of the industry’s U.S. 

shipments (2.9%). We conclude from this comparison that exporting reduced the volatility of the 

industry’s total shipments.9

 

 The normalized volatility comparisons for the Medical Equipment and Supplies industry 

are representative of the results for the 85 manufacturing industries as a whole (The results for 

each of the industries are reported in a table in the Technical Appendix.). For 21 of the 85 

industries, both the normalized volatility and the standard deviation of the industries’ total 

shipments were smaller than their counterparts for the industries’ U.S. shipments. The smaller 

standard deviations for these industries indicate that exports were a particularly good hedge 

against fluctuations in demand in the U.S. market.10 For an additional 40 of the 85, the 

normalized volatility measure was lower for total shipments than for U.S. shipments (but the 

standard deviation was not), which indicates that exporting reduced the volatility of the 

shipments of these additional industries relative to their 2008 values. 

Among the 85 industries, the Leather & Hide Tanning & Finishing, Audio & Video 

Equipment, Apparel Accessories & Other Apparel, Communications Equipments and Engine & 

Turbine & Power Transmission Equipment industries experienced the largest percentage 

reductions in the normalized volatility of their total shipments as a result of their exports.11 In 

general, industries with higher export shares experienced larger reductions in the normalized 

volatility of their total shipments. 

As a sensitivity analysis, we recalculated the normalized volatilities using the mean value 

of shipments between 2000 and 2008 in the denominator rather than the 2008 value of 

shipments. The results are similar. For 21 of the 85 industries, both the normalized volatility 

and the standard deviation of the industries’ total shipments were smaller than their counterparts 

for the industries’ U.S. shipments. For an additional 33 of the 85, the normalized volatility 

measure was lower for total shipments than for U.S. shipments (but the standard deviation was

 In the Technical Appendix, we identify the technical assumptions that underlie this economic interpretation. 

10 Specifically, they imply that the covariances between the industries’ U.S. shipments and their exports were 

negative.

not), which indicates that exporting reduced the volatility of the shipments of these additional 

industries relative to their 2008 values. 

 Finally, we also examined whether the results are different when we focus the analysis on 

exports to OECD member countries. We defined a U.S. industry’s OECD shipments as the sum 

of its U.S. shipments and its exports to other OECD countries. Of the 85 industries, there are 55 

industries for which exports to all countries reduced the normalized volatility of their shipments 

and exports to other OECD countries also reduced the normalized volatility. There are six 

industries for which total exports reduced the normalized volatility, but exports to other OECD 

countries did not. There are two industries for which exports to other OECD countries reduced 

the normalized volatility of their shipments, but total exports did not. 

5. Conclusions 

 Both the company case studies and the industry-level analysis of the U.S. manufacturing 

sector indicate that non-U.S. sales, including exports from the United States, reduce the 

normalized volatility of the value of total shipments of U.S. manufacturers. The value of 

shipments is a measure of U.S. manufacturers’ revenues and not their profits, so the reduction in 

the volatility of shipments does not necessarily imply a reduction in the volatility of the 

companies’ profits. However, the two are closely connected as long as costs are a steady share 

of revenues.

Technical Appendix 

This appendix provides further details on some of the more technical aspects of the 

analysis in the paper. 

Adjustments to the shipments data to remove predictable trends 

In this analysis, we are measuring the unpredictable variation in the shipments series. We 

are not trying to measure all time series variation in the shipments series, which would include 

variation in shipments over time due to a deterministic linear trend in the series. For each of the 

series, we estimated industry-specific means and linear trends for the 2000-2008 sample using 

Ordinary Least Squares. These simple regression models indicate that there is a positive trend in 

each series that is statistically significant at the 1% level. On this basis, we conclude that the 

expected values of the variables are not fixed over time. We calculated the unpredictable 

component of each of the shipments series as the residuals of its linear trend model. 

Next we calculate the standard deviation, which is the square root of the variance. The 

general definition of variance is that it is the average squared difference between a variable and 

its expected value. If the expected value happens to be constant over time, then this is the 

average squared difference between the variable and its time-invariant mean. For these 

shipments series, however, the expected value is not time-invariant. It increases over time 

according to the linear trend models. In each year, the actual value of the variable differs from 

the expected value due to unpredictable variation. When we de-trend the shipment series by 

subtracting the expected value from the actual value, we are isolating the unpredictable variation, 

which has mean zero by construction over the 2000-2008 sample period. The de-trending does 

not require an economic theory about the determinants of the trends or assumptions about 

whether the trends are the same for U.S. shipments and total shipments or across industries. 

We measure the normalized volatility of the shipments data as the ratio of the standard 

deviation of the residuals to the most recent value of the shipments variable, which is the value in 

2008. As a sensitivity analysis, we re-calculate the ratio using the average value for shipments 

between 2000 and 2008 as the denominator. 
Manufacturing and Services Economics Brief No. 3 

12 The Impact of Exporting on the Stability of U.S. Manufacturing Industries

Our measure of normalized volatility is similar to the conventional coefficient of 

variation statistic. However, the coefficient of variation is based on the standard deviation of the 

original series, not the standard deviation of the unpredictable components of the series. We 

modify the coefficient of variation statistic to address the predictable trends in the shipment 

series. 

Economic Interpretation of the Comparison of Normalized Volatilities 

For industries in which the normalized volatility of total shipments was lower than the 

normalized volatility of U.S. shipments, we infer that exporting reduces the volatility of the 

industry’s total shipments. This interpretation is based on a counterfactual comparison with 

specific assumptions. We are assuming that the volatility of the industry’s U.S. shipments would 

be the same in the absence of exports (a hypothetical scenario) as it is with exports (the actual, 

observed outcome). This is implied by a more technical assumption – that the U.S. industry’s 

marginal cost of production is separable between shipments to the different geographic markets. 

As long as prices are set based on the U.S. manufacturers’ marginal costs, exporting will only 

affect the value of shipments to the U.S. market if it affects the marginal cost of supplying the 

U.S. market. If marginal costs are separable between the destination markets, then exporting will 

not affect the value of shipments to the U.S. market, even if there are fixed costs of production 

that are shared across the destination markets or fixed costs of accessing export markets. 

This technical assumption is consistent with the most common economic models of 

international trade. It holds if production costs exhibit constant returns to scale, as in the 

classical Heckscher-Ohlin and Ricardian models of international trade, and the industry is not 

large enough to have a significant impact on factor prices. It also holds for models with 

increasing returns to scale and imperfect competition, as long as there are constant marginal 

costs, as is the case in Helpman and Krugman (1985) and many related models of international 

trade.

Relation to the Economics Literature 

Most of the economics literature that relates volatility to international trade focuses on a 

single source of uncertainty, exchange rate volatility. Examples of this literature include 

Bacchetta and van Wincoop (2000), Koray and Lastrapes (2001), Bahmani-Oskooee and Hegerty 

(2009), and Ekanayake et al. (2010). In contrast, the comparison of normalized volatilities in 

this paper avoids disentangling the contributions of different sources of uncertainty that are 

associated with exporting, like fluctuations in aggregate demand in the foreign country, shipping 

costs, and exchange rates. We demonstrate in this paper that it is not necessary to quantify the 

separate contribution of each source of volatility in order to determine whether exporting 

reduced the volatility of an industry’s total shipments.
