Agricultural Trade Multipliers: Effects of Trade on the U.S. Economy

Contents
 

2008 Data Overview

Record-setting U.S. agricultural export values in 2008 generated employment, income, and purchasing power in both the farm and nonfarm sectors. ERS estimates that each dollar of agricultural exports stimulated another $1.36 in business activity in 2008. The $115.4 billion of agricultural exports in 2008 (the estimated value as of June 2009) produced an additional $157.2 billion in economic activity for a total economic output of $272.6 billion. Every $1 billion of U.S. agricultural exports in 2008 required 8,000 American jobs throughout the economy. Calendar year 2008 agricultural exports required 920,000 full-time civilian jobs, which included 608,000 jobs in the nonfarm sector.

Introduction

As the world's economies become more integrated, global trade and the links between countries grow ever deeper. Through the first three quarters of 2008, the world economy grew at the highest rate ever recorded, fueling demand for U.S. agricultural commodities.  U.S. agricultural trade is a significant contributor to the overall U.S. economy, with impacts felt in countries worldwide.  The United States is a net exporter of agricultural products, with its $35 billion surplus helping to offset some of the U.S. nonfarm trade deficit, which reached more than $960 billion in 2008.

Trade has always been important to U.S. farm and rural economies. From early colonial days, when tobacco and cotton were the dominant export commodities, to more recent times, in which grains, oilseeds, and processed foods account for the bulk of exports, agricultural trade has contributed to U.S. economic growth. Trade agreements have expanded agricultural trade with developed and developing countries and, in turn, have created growth opportunities for U.S. agriculture. Free trade agreements, such as the North America Free Trade Agreement, have lowered trade barriers and created additional consumer demand in foreign nations for U.S. agricultural commodities.  The purchasing power these nations acquire when their products are sold in the United States and elsewhere helps satisfy that demand.
 
In 2008, domestic harvests declined slightly from 2007 levels, but U.S. agricultural export value increased at a record-setting rate, generating higher farm and economywide income than the previous year. High prices for farm commodities contributed greatly to the value of 2008 agricultural exports. Foreign demand for these exports was spurred by continued economic growth in other countries and a weakened U.S. dollar. The U.S. dollar continued its slide against most major currencies in 2008, making the price of U.S. goods more competitive abroad. Except for a small turnaround against the British pound, the value of the U.S. dollar declined against the euro, yen, and Canadian dollar, making U.S. products more affordable to holders of those currencies.

Canada and Mexico are the leading U.S. trading partners, followed by Japan and, as of 2008, China. Together, these nations buy 50 percent of U.S. exports. Meanwhile, U.S. imports of agricultural goods did not slow in 2008, despite the weakened buying power of the U.S. dollar. U.S. imports from Canada rose from $13.8 billion in 2005 to $18.9 billion in 2008, a 38-percent increase and 22 percent of 2008 U.S. agricultural imports. In 2008, U.S. agricultural imports from Canada totaled $18.9 billion, a 38-percent increase over 2007. In the same period, Canada accounted for 22 percent of U.S. agricultural imports. Together, Canada, Mexico, and the European Union (EU) supplied 55 percent of all U.S. agricultural imports in 2008. Since 2005, the 27 countries that make up the EU have been either the first or second largest supplier of U.S. agricultural imports. If the EU is considered as a single supplier, then China becomes the third largest supplier—U.S. imports from China rose from $2.9 billion in 2005 to $4.9 billion in 2008. U.S. consumers in 2008 continued to demand a large variety of imported goods and were willing to pay a premium for them.

Agricultural trade is most importantly a generator of output, employment, and income in the U.S. economy. For every dollar spent on U.S. exports in 2008, another $1.36 was created in the U.S. economy to support the exporting activity. ERS Estimates of Agricultural Trade Multipliers (ATM) show that every $1 billion of U.S. agricultural exports in 2008 required 8,000 American workers engaged in either direct or indirect supporting activities. For more information on these estimates and the tools used to calculate them, see the ATM Assumptions and Methodology pages.

Impacts of Agricultural Trade in 2008

The impacts of agricultural trade on the U.S. economy change from year to year. Just as the composition of the agricultural export "basket" changes yearly, so, too, do the direct and indirect impacts on the economy. The structure of the U.S. economy also changes, which influences the impact of agricultural exports. The domestic economy is now dominated by the service sector, and the high level of supporting activity in the service industries reflects that structure.

In calendar year 2008, the $115.4 billion of U.S. agricultural exports (June 2009 estimate) produced an additional $157.2 billion in economic activity for a total of $272.6 billion of economic output (see U.S. economic activity triggered by agricultural trade, 2008ERS). (As of October 2009, the value of U.S. agricultural exports in 2008 has been revised downward to $115.2 billion.) In the same period, the value of supporting activity continued to climb, surpassing the $100 billion mark for the fourth consecutive year. Agricultural exports generated 920,000 full-time civilian jobs, including 608,000 jobs in the nonfarm sector. Farmers' purchases of fuel, fertilizer, and other inputs to produce commodities for export spurred economic activity in the manufacturing, trade, and transportation sectors. (For information on how the data are derived, see ERS Estimates.)

The production equivalent of over one-fourth of U.S. cropland moved into export channels in 2008. Of raw crops, the United States exported 40 percent of food-grain production, 15 percent of feed grains, and more than 43 percent of oilseeds. While oilseed exports as a percentage of production held steady, both food and feed grains percentages decreased significantly from 2007 levels. However, because the value of all agricultural exports increased more than imports, net agricultural exports in 2008 contributed $35.0 billion to the overall U.S. economy, an increase of $16.4 billion over 2007.

Exports Generated New Business, Added Jobs

Of the $115 billion in direct U.S. agricultural exports in 2008, the value of exported raw products accounted for $43.7 billion, compared with $44.9 billion for processed commodities and $26.9 billion for trade and transportation services. Over $157 billion of supporting, or indirect, activity was generated by agricultural exports in 2008, encompassing the value of activity required to facilitate the movement of exports to their final destination (e.g., computer and financial services, warehousing and distribution, packaging, and additional processing). The service sector accounted for $69.6 billion of the total. Nonfarm sectors of the economy accounted for about 79 percent of this additional economic activity.

Employment required to produce, transport, and service agricultural exports soared from 808,000 jobs in 2007 to 920,000 jobs in 2008. The increase was largely attributed to price changes, which affect the estimates of workers per billion dollars of exports. Changes in the export commodity mix and the volume of goods exported also contributed to the increase. Of the full-time civilian jobs related to agricultural exports in 2008, farmworkers accounted for more than 312,000. Based on a Bureau of Labor Statistics estimate of 1,818,000 full-time-equivalent agricultural workers in 2008, approximately 17 percent of the U.S. farm workforce produced for export during the period. In 2008, 608,000 jobs in the nonfarm sector were involved in assembling, processing, distributing, and servicing agricultural products for export, an increase of 71,000 over 2007 levels. About 110,000 of those jobs were in food processing, 197,000 were in trade and transportation, 65,000 were in other manufacturing sectors, and 237,000 were in other services.

In 2008, nonbulk agricultural exports generate more total business activity than bulk exportsd

Bulk exports have a smaller proportional effect on the nonfarm economy than processed, or high-value, exports.  In 2008, bulk exports of $48.4 billion generated an additional $44.3 billion of business activity, while nonbulk exports of $67.0 billion generated $112.9 billion (e.g., $0.92 additional output per dollar of bulk exports, $1.69 for nonbulk exports, and $1.36 for all agricultural exports).

Of the additional business activity attributed to bulk exports, the service sector accounted for 59 percent and food processing accounted for 0.5 percent. By contrast, the service sector and food processing accounted for 39 percent and 11 percent, respectively, of the additional business activity generated by nonbulk exports. Of the 920,000 jobs related to U.S. agricultural exports, 598,000 (65 percent) supported nonbulk exports.

Impacts of Agricultural Imports on U.S. Output

It is not possible to measure the total economic activity associated with imports because there are no end-use data on imports available. When imports enter the United States, their value is recorded. After that, they are no longer tracked as imports but instead enter the general domestic economy to be used in the same fashion as domestically produced goods.

The end-use of a product determines its multiplier effects. Imports can be put into inventory (an almost negligible multiplier) or can be used in a highly processed product (a very large multiplier). Thus, without end-use data, the indirect, or supporting, impacts of actual agricultural imports cannot be measured in terms of output, employment, value-added, or as a multiplier. Only the value of imports as measured upon entry into the United States can be discerned (direct effects).

Imports can be assigned the generally held view of an economywide domestic business multiplier of between 2.00 and 2.50 because activities associated with "absorbed" imports are the same as those associated with any other domestic commodity. After adjusting for inflation from the benchmark year (2002) to 2008, the average output-weighted domestic business multiplier in 2008 for all U.S. business can be calculated as 2.43.

To illustrate the point, consider that almost all fish products are imported. If reliable statistics on consumer demand and consumption of fish were available, the supporting activity required to deliver imported fish could be measured. But this measure would reflect only part of the contribution of fish imports to the economy because fish is also turned into meal and feeds, processed products, pet foods, and other uses not related to direct human consumption. These uses become completely intertwined with domestic production. Finally, to fully measure all fish outputs, one would also have to separate the movement of imported fish products from the small but growing amount of products from domestic farm-raised fish.

Due to these data limitations, the economic impact of imports described here is the value of imported products as if they were produced in the United States and then assigned the value of that activity as a theoretical loss of economic activity to the United States. The only actual "loss" to the U.S. economy that can be measured is the actual value of agricultural imports. After the imported product is absorbed into the U.S. economy, the supporting activity required to deliver the imported goods to final consumers can be assigned a general business multiplier, usually, between 2.00 and 2.50.

The domestic output effect of the $80.4 billion of U.S. agricultural imports in 2008 was $199.5 billion. Like exports, imports generate jobs in the data processing, financial, legal, management, administrative, marketing, and transportation sectors. Each dollar spent on agricultural imports in 2008 would have required another $1.48 in supporting goods and services if those imported items had been produced domestically, indicating an output multiplier of 2.48.

U.S. agricultural trade had a positive effect on all sectors of the economy in 2008. Even the food processing sector's theoretical loss in trade in high-value processed products (-$9.7 billion) was offset by gains from trade in bulk products and the supporting activity associated with bulk and nonbulk trade. The farm sector's $76.5 billion of output associated with agricultural exports more than offset the $40.3 billion of farm output implicitly lost because of agricultural imports. The nonfarm sectors, including food processing, gained $36.9 billion in total output via the agricultural trade balance, creating about 108,700 jobs and generating $18.0 billion in income. The U.S. economy gained a net $73.1 billion in output (after the theoretical loss to agricultural imports is considered).

Outside of farming and food processing, the United States gained a net $5.9 billion in 2008 from direct agricultural trade--that is, exports minus imports of agricultural goods that are neither farm nor processed goods (pharmaceuticals and adhesives, for example)--and $24.2 billion in total output because the direct plus indirect value of these exports was greater than that of the imports.

Total Jobs Required Per Billion Dollars of Agricultural Exports Dropped in 2008

In 2007, 9,000 workers were required to deliver each billion dollars of agricultural exports from the farm to their final destination. In calendar year 2008, that number fell to 8,000 workers. The farm sector is the largest generator of jobs related to agricultural exports. Because farm price increases continued their substantial rise begun in 2007, particularly for the commodities that are included in bulk exports, the sector generated less employment per dollar of exports than other sectors.

When farm prices are low, customers buy large amounts of bulk grains and oilseeds. This activity creates jobs on the farm and in the supporting transportation and distribution industries, but job growth bypasses the processing and manufacturing sectors. In 2006, the United States exported record setting quantities of bulk commodities. Because the volume of exports largely determines the overall supporting labor requirements, many farm and farm-related jobs were generated as a result.

According to USDA's National Agricultural Statistics Service, prices received by farmers for food grains, feed grains, and oilseeds increased between 18 and 47 percent from 2007 to 2008. Over the same period, the total value of U.S. bulk exports increased from $32.9 billion to $48.4 billion, or 47 percent.

Because the change in agricultural export value from 2007 to 2008 was mostly price driven, the actual number of jobs generated per billion dollars of exports decreased over the period. In addition, because many farm and closely related industry jobs are dependent on bulk exports, for which prices rose significantly in 2008, farm jobs generated by agricultural exports fell in 2008. By comparison, in 2006, bulk exports created more jobs than nonbulk exports because of high volume and low farm prices. In 2008, the estimates returned to the historical pattern of nonbulk exports generating more jobs per billion dollars of exports.

While the jobs per $1 billion of exports fell again in 2008, total employment supporting U.S. agricultural exports reached new heights due to increases in supporting nonfarm employment. Not since the early 1980s, when $35 billion to $45 billion of agricultural exports generated an estimated 1-1.2 million jobs, has job creation reached higher than the level in 2008 (920,000). Nonfarm job growth (608,000) increased significantly for the second straight year in 2008. ERS estimates that $38 billion of agricultural exports created 1.1 million jobs in 1983, a multiplier of 29,000 per billion dollars of exports (Foreign Agricultural Trade of the United States, 1984). In 2008, three times the value of exports created almost the same level of jobs as in 1983, but because of prices, productivity, and structural/technological changes in the intervening years, the number of jobs per billion dollars of exports declined to 8,000 workers.
